Studio Headphone Amplifiers

Notes: Apogee Groove is the best portable USB DAC and headphone amp for listening to music on your Mac or PC. Groove takes the same high quality audio technology found in the world's most prestigious recording studios and delivers it to your laptop. Connect Groove to your computer's USB port and your headphones or powered speakers to Groove's audio output. It's that easy. Groove's output provides ample power at any impedance and Apogee's Constant Current Drive technology makes your headphones sound their best. You'll be amazed by the difference in sound quality - the precise stereo image, punchy bass and stunningly clear high-hats.

For 30 years Apogee has been an innovator and industry leader in digital audio recording. From rock to classical, hip-hop to country, and reggae to jazz, the world's most successful artists, producers and audio engineers rely on Apogee gear to capture GRAMMY winning recordings. Now, for the first time, Apogee Groove takes this same recording studio technology and makes it available in a simple take-anywhere device dedicated to delivering the ultimate listening experience.

Whether you're building your FLAC file collection or subscribing to a premium music streaming service, you are investing in a higher quality listening experience. Groove unlocks the full potential of that experience, revealing definition, clarity and details like you have never heard before.

With professional headphones, your laptop and Groove, you can mix or make music anywhere. Groove's reference quality sound insures you will hear every detail of your project as it would sound in the studio.

Groove's Constant Current Drive output stage dynamically compensates for the nonlinearities - acoustic, mechanical or electrical - of any connected headphones, resulting in lower distortion and a more linear frequency response. Whether listening through earbuds or "hi-fi" headphones, you'll discover a new level of fidelity, clarity and detail.

Groove also features a Quad Sum DAC design which employs four digital-to-analog converters per channel to achieve the highest dynamic range and lowest distortion (THD+N) of any device in its class.

ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequaled dynamic range, ultra low distortion, and unmatched audio clarity free from input jitter.

If you're a music lover and you want the best listening experience, one of the key ingredients in the quality of your sound is the digital-to-analog converter or DAC.

A DAC takes the digital information on your computer and translates it into analog sound you can hear through your headphones and speakers.

Your computer has a DAC built-in, however without a high quality DAC like Groove, you will miss out on much of the subtlety, detail and dimension of music you listen to - regardless of what headphones or speakers you use.

Notes: The ART HeadAmp4Pro could be the most fully featured ultra compact headphone amplifier in its price point on the market today.

Packing as many features as possible into the small format chassis, the HeadAmp4Pro has five stereo headphone outs, each with their own volume control. A separate footswitchable XLR input (with phantom power) allows instant talkback to any one, or all of the connected headphones. Input matrix allows the listener to audition any or all auxiliary inputs for maximum versatility.

Although designed for home and project studio, the HeadAmp4Pro may easily be the ideal solution for teaching stations and conferencing communication networks.

Notes: The HeadAmp6 is a fully featured six channel stereo headphone amplifier that includes six auxiliary inputs to allow separate "more-me" mixes on each headphone channel.

Each output channel has a dual function Balance Control which will pan between Left & Right input of the main signal bus, or vary the mix between the main stereo signal bus and the auxiliary input for that respective channel.

Each output channel includes one front and two rear panel stereo 1/4" TRS head-phone jacks for ease of installation and quick patching capability. Mono, Mute L, and Mute R select buttons and on each channel select between four operating modes; 1) Stereo, 2) Mono Left, 3) Mono Right, 4) Mono Both (Left & Right) for versatile monitoring solutions. Independent output level controls on each channel personalize monitoring levels.

Input options include XLR and 1/4" TRS balanced inputs with matching "Thru" jacks for bridging multiple units. An additional front panel stereo 1/4" TRS Direct In jack for quick patch override of the rear panel inputs is included for quick insertion of any stereo source. Master Volume control sets the main signal bus level. Eight-segment precision LED level metering on the main bus and four-segment indicators on each output channel provide visual feedback of the signal level at all key points.

Notes: Sometimes floor monitors are a problem. There isn't enough room for them onstage or someone sits in and can't hear the monitors or the drummer can't hear them well enough. Or perhaps it's a pick-up gig or a rehearsal and you didn't have enough time to set them up. In any case, sometimes it would be preferable just to put on headphones and somehow connect them to the PA. That's where a headphone tap comes in. This is a passive device with an input to connect the PA or monitor amplifier and an output to connect the headphones. A volume control regulates the headphone level and internal resistors keep the unit's impedance high enough to protect the headphones. It also protects the amplifier from encountering too low a load impedance while powering tap units, the speaker system or several tap units by themselves.

The HeadTAP will also work with a stereo headphone amplifier for use in recording situations when you want to add headphones for additional performers.

Notes: A performer needs to hear him/herself through headphones exclusively or mixed with the output of a mixer, CD player, tape deck, or other stereo line level source. Only the mic signal, however, should be going to the main mixer.

Connect the MyMONITOR between the mic and line source, and the mixer. The mic and line monitor levels can then be adjusted for mix and volume through the headphones. Only the mic signal will go to the board. And since the MyMONITOR can be AC or battery powered, the unit can be used on a large stage or wherever there is no AC outlet nearby. Dynamic or condenser mics can be used since phantom power would come through the mic thru jack from the mixer or other source.

Notes: The HeadAmp4 offers 1/8" as well as 1/4" inputs and outputs as well as lower noise, lower distortion and more output in a new custom extruded stackable metal case.

Ideal for virtually any home or project studio, the ARTcessories HeadAmp4 easily adds additional headphone outputs to any mixer, computer audio interface, workstation, iPod, media player or laptop without creating any additional load on the existing headphone source.

Individual level controls for the 4 x headphone outputs, 1/4" and now 1/8" connections allow the HeadAmp4 to connect to virtually any source, and drive any headphone configuration including studio phones, in-ear monitors or custom ear pieces or any combination of the above.

Notes: The ultra compact MicroMon MA400 is the ideal personal monitor mixer for the performer who always asks for "more me".

The MA400 features XLR thru jacks and provides superb noise free operation. Just connect your mic to the mic input and send a line from the mic thru to your main mixer. You can even use studio grade condenser mics, as the MA400 will pass +48V phantom power, if your mixer is so equipped. The phones jacks accept both 1/4" and 1/8" headphone and earbud connections, making the MA400 ideal for hardwired IEM (in ear monitor) applications, such as singing drummers and keyboardists. The MA400 comes with a dedicated 12V DC power supply and an LED to indicate when it is powered up.

Capable of stereo or mono operation, the MA400 is a powerful little mixer that allows you to control two independent sources, a microphone and the monitor feed from your main mixer. Simply adjust the mon level control to a comfortable setting and then dial in all the "me" you want with the mic level control.

Notes: The POWERPLAY P1 Personal In-Ear Monitor (IEM) Amplifier puts control where it's most useful - right at the artist's fingertips. Whether on stage or in the studio, the P1 provides performers and recording artists with a dependable and affordable personal monitoring solution.

The P1's high-power headphone output ensures that as the band gets louder, you'll still be able to hear every nuance of your performance. And the P1's simple user interface makes it easy for everyone to dial in a perfect mix every time.

Using the P1 also helps protect your hearing in two ways. First, thanks to a built-in current limiter, unexpected peaks in signal level won't get to your ears. Second, the simple act of wearing headphones or earbuds helps isolate your ears from loud stage volume of instrument amps and monitor wedges. With the P1, you can clearly hear your own performance and blend in the ideal amount of the rest of the band.

Dual XLR inputs allow 2-channel, mono or stereo operation with a convenient mix function which allows you to run two sources into the P1 and dial-in exactly what you want to hear as you perform. Two simple controls, Level and Balance, help you achieve the perfect mix in an instant. The P1 lets you take control of what you hear and allows the engineer to concentrate on providing the audience the best listening experience. Plus, setup is so fast and easy, letting you concentrate on putting on the best performance when you hit the stage.

One little 9 V battery lasts up to 12 hours, so the P1 will go as long as your next show or studio recording session! Or, use the optional PSU-SB DC power supply for the ultimate in dependable power. And the P1's metal chassis is built like a tank to handle even your most-demanding and energetic performance. Small enough to hang on your belt - or mount on a mic or drum stand, the P1 puts complete balance and volume control in your hands.

Notes: Whether you're a keyboardist, drummer, or other musician whose performance keeps them anchored in one spot, the P2 Ultra-Compact Personal In-Ear Monitor Amplifier was designed specifically for you. A convenient hard-wired personal in-ear control center, the P2's belt pack puts monitor control right at your fingertips, plus it's powerful, lightweight and ultra-easy to use.

You can use your favorite headphones, earbuds or custom-molded professional InEar Monitors (IEMs) with the P2, thanks to the top-mounted, standard 3.5 mm (1/8") stereo output jack.

Because your monitor is crucial to your performance, P2's XLR / TRS combo input connector features a locking mechanism to prevent accidental mic cable disconnects. Just press the tab next to the bottom-mounted connector to release the cable at the end of the gig. It is important to note that P2's XLR input accepts balanced line signals taken directly from your mixer, allowing you to control the volume of the onboard amplifier.

P2's internal Mono/Stereo switch lets you choose the mode that best fits your needs. When using your mixer's aux send or any other mono source, move the switch to the Mono position. For connecting to a headphone output or other stereo source, simply set the switch to Stereo and use an XLR-to-TRS or TRS-to-TRS (male to male) cable.

The P2 features an extremely high-quality level control with on/off switch for dialing in the perfect level every time. Designed for long life and super-smooth performance, this detented control stays where you put it. When you do need to move around, say to change your amp or stomp settings, P2's built-in belt clip will always keep it close at hand. Just slip the P2 onto your waistband or belt- and let the good times roll.

When it comes to wired monitor applications, you simply will not find a better or more affordable solution than the amazing P2 Ultra-Compact Personal In-Ear Monitor Amplifier. Built-like-a-tank to be "drummer proof", and featuring an impact-resistant metal chassis, the P2 was made for the road and will give you many years of dependable, highest-quality performance.

Notes: Clever little valve-based headphone amp from Korg's NuTekt DIY range. Some basic assembly required but no soldering. Fully customisable for advanced users.

Supplier's notes:
The HA-S is a Nutube-equipped DIY Headphone amp kit that will let you enjoy the highest quality audio anywhere. No soldering is required, so even if you are new to the world of DIY, you will be able to assemble the HA-S to add a warm, analog tube-driven signal boost to any sound source in no time! Build your own Headphone amplifier This DIY HA-S kit allows you to build your very own Headphone amplifier in an easy and fun way, without any soldering needed. Not only that, it provides the authentic vacuum tube sound that audiophiles know and love. Built-in Nutube Nutube is a new and revolutionary fully analog vacuum tube developed by KORG INC. and Noritake Itron Corporation. The same as a conventional vacuum tube, Nutube is constructed with an anode, grid and filament, and operates as a complete triode tube, effectively generating the response and same rich harmonic characteristics of conventional vacuum tubes in a more compact, stable and energy-efficient way. The transparent case of the HA-S delivers a glimpse into this technology; allowing the glow of the tube to be visible at all times. Energy efficiency The filament of the Nutube is powered by a DC to DC converter, which consumes less electric current and thus allows for a longer battery life than other vacuum tube equipped amplifiers. The design is so efficient that the HA-S can drive the Nutube with a line voltage of 26 V using only two A4 batteries., for a rich and authentic vacuum tube sound. Sound possibilities The HA-S has a special NFB (Negative Feedback) switch, that allows you to choose from a high fidelity clean and pristine sound, or a warmer, more harmonically rich sound as expected from a vacuum tube. When the NFB switch is OFF, the harmonics present in the Nutube (triode tube) will be amplified to create a sound rich in harmonics, warmth and textures. When the NFB switch is ON, the distortion ratio and frequency characteristics will be modified, creating a really detailed and clean sound. For further sound modification, we have included two OP amp options for the output: the premium audio oriented "MUSES01" and the industry standard NJM4580, both from JRC. These can be easily replaced so even the most purist audiophiles will be able to customize and adapt the sound of their HA-S to heir heart's content. For advanced users who want to customize their amplifier even more, the circuit diagrams are readily available, making it really easy to change discrete components and make your own and unique headphone amp matching your desired tone and performance -, the possibilities are endless!

Notes: Designed with Brian Hamilton from smallsound/bigsound for OBNE demo boards, Old Blood Noise deemed it a reasonable idea to offer every bedroom player a way to not annoy those around them. Simply plug in the output of your pedalboard to the headphone amp, plug in headphones and blast your volume. Play whatever you like, you're the only one who can hear. Or a buddy can plug into the additional Headphone output. Headphone output is mono out.

Two 1/4 Headphone Output jacks allow two users to simultaneously listen.

Notes: Ear-Pleasing sound:
Designed for musicians and performers who demand mobility without compromising audio quality, the HP2 personal headphone amplifier is a great choice for driving wired in-ear monitors (IEMs), as well as headphones. PreSonus HP-series headphone amplifiers have long been popular for their loud, clean, clear sound and roadworthy built quality. The new HP2 delivers these qualities in an easily affordable, stereo device so you'll hear every note and beat clearly wherever your music takes you.

One for the road:
Portable and compact, the HP2 gives you all you need to drive your headphones or in-ears without complicating your setup. It sports two XLR line-level inputs and one stereo 1/8-inch headphone output with volume control. Operation can be switched between stereo and mono, and a Pan knob is provided. Like all PreSonus gear, it's built to take the rigors of life on the road. And it mounts on a microphone stand or clips to your belt. Simple, easy to use, built to travel, has the right features, sounds great. That's how we roll at PreSonus.

Power all night long:
When you're playing an extra long show or two shows back-to-back, having to stop and change batteries on your headphone amp is a hassle you don't need. No worries! HP2 stands for "Has Power 2 Spare." The HP2 can be powered with an external DC power supply or a nine-volt battery that lasts more than seven hours and includes an LED battery indicator. So you can play those extra-long gigs and hear your monitor mix perfectly - all night long.

Notes: Are you and your session players and bandmates tired of straining to hear underpowered headphones? That's why Jim Odom and his jambalaya-fueled team of engineers designed 150 mW headphone amps for the HP4 headphone-distribution system.

These headphone amps are not just loud enough for session and stage use, they're loud enough to explode the oysters in a Po' Boy sandwich. Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to heariassuming they are capable of hearing. Be careful with that level control.

Simplicity is the HP4's hallmark. You get left and right line inputs, left and right line outputs with level control, and the 4 x headphone outs. You can globally mute the headphone outs, adjust the overall headphone level, sum the stereo signals to mono, and mute the rear-panel Monitor outputs.

The HP4 can sit on a tabletop or can be screw-mounted to a standard rack tray (not included), where it requires just 1/3 rackspace. And if your needs grow, you can use the line outputs to feed the inputs of a second HP4 or an HP60. Chain as many headphone systems as you need.

So listen up. Quit struggling with mediocre headphone amps. Get the HP4 and hear everything loud and clear. You owe it to your music.

Notes: "Turn my headphones up!" "More me, I can't hear myself!" "Turn down that click!" It gets old. Change that tune with the HP60 headphone distribution system. The HP60 is more than just a half-dozen headphone amps, it's a field-tested solution to a host of common headphone-monitoring problems.

Let's start with "turn my headphones up." Each of the HP60's six headphone amps has its own level control and puts out 150 mW, which is loud enough to drive the alligators out of the Louisiana swamps. If they can't hear this headphone system, they're stone deaf.

More likely they'll scream, "turn it down, you're killing me!" Problem solved.

Now let's solve "turn down that click." The HP60 features two sets of line-level, stereo inputs that are routed to all six headphones; a Mix control that sets their relative levels for each headphone output. So you can feed the main control-room mix to channel A and the click to channel B and use the Mix controls to individually raise or lower the click relative to the main mix for each musician. Problem solved.

As for "more me," in addition to the two pairs of main stereo inputs, you get an external stereo input pair with level control for each headphone channel. A Mono switch lets you sum the left and right inputs. Additionally, a mute switch is provided for each headphone output.

So you can send each person a feed of just their instrument or voice and can control the level separately for each. Problem solved.

With the HP60, when you talk, everyone listens. Hit the Talk button and use the talkback-mic input and your favorite dynamic mic to tell 'em what to do. You can even use a footswitch to control the talkback hands-free.

Each channel also has stereo line outputs that can send a copy of the line-level headphone-channel mix to additional headphone amplifiers or monitor systems. So if you have a large band and need more than six headphones, you can chain two or more HP60s.

So get the problem solver, the most flexible and advanced headphone-mixing system in its price class: the PreSonus HP60.

Notes: Channel Your Sound:
You've positioned your microphones, set your levels and everyone's ready to record. Now, you need a way for each performer to hear themselves. That's where the Samson QH4 comes in... The QH4 is a 4-channel headphone amplifier designed to distribute your audio to up to four individual headphones, each with its own volume control. Its compact design is perfect for use with any studio or desktop workstation, as well as with your laptop or smartphone when you're recording on the go.

In Side... And Out:
The QH4 features two balanced 1/4" inputs to connect with your mixer or recording interface, as well as a stereo 1/8" Aux input that's perfect for playing music via your smartphone or another line level device. In addition to the four stereo 1/4" headphone outputs, the QH4 provides a 1/8" Aux Out that can be used to daisy chain multiple QH4s together.

The four independent high-power amplifier channels deliver clean, crisp audio to up to four sets of headphones, operating between 16-600 ohms. And power does not diminish even when all four channels are being used. Engineered with an ultra-low noise floor and wide dynamic range, the QH4 is a tremendous value compared to other headphone amplifiers on the market. Also, the QH4's Master volume control and Mute switch make controlling the overall level of your headphones a breeze.

Check Your Phase:
Before bouncing your mix, you should always check to ensure that it's compatible with mono speaker systems. The QH4 features a global Mono button, which allows you to quickly check the mono compatibility of your tracks. If you notice that some of your audio is missing, you should check the phase of your recordings. This feature also allows you to take a split left and right feed from a stereo interview and send both tracks to each side of your headphones. This is great for quickly monitoring a podcast or recording with split tracks.

Whether you're tracking multiple performers in a studio, recording a podcast, watching a video with friends or just kicking back listening to some tunes, the QH4 provides great sound at an amazing value.

Notes: The S-phone is a versatile single rack space four channel headphone amplifier, loaded with advanced features that provide tremendous flexibility for monitor and cue mixing.

The Master Input features an input level and LED meter to control and display the overall stereo input. Each of S-phone's four channels includes three Headphone Outputs with an overall Volume control and individual Level meters. A convenient Stereo Auxiliary input is available on each channel so that individual line signals from direct or buss outputs can be mixed with the main stereo input.

The Balance control adjusts the ratio of the Main and Auxiliary signal or the left to right balance (based on the setting of the ST/2CH switch) so that each headphone mix can be further tailored for a particular listener's individual needs ("More Me").

For greater sonic control, S-phone also features a 2-band equalizer on each of the four channels. A master Stereo Aux input on the front panel is also supplied for inserting a second signal to all headphones.
