Back catalogue: All genres

Notes: The Allen & Heath ZED-24 has an incredibly advanced feature. It has 23 independent sources to the mix, 10 independent outputs and 4 aux sends. Configurable USB audio input/output makes it easy to capture stereo recordings, playback and effects, a unique dual stereo input capability and some very advanced monitoring facilities. In fact, the ZED-24 mixer is so packed full of great features that you'd think it would cost much, much more.

Getting audio to and from a computer easily is now a common requirement for live sound and music production. The way this has been implemented on the ZED-24 is super-flexible and super-easy. No longer do you need to fiddle around the back of your PC to get to the soundcard inputs, only to find that the levels are all wrong and noisy. Just plug in a USB lead to your ZED-24, select the USB routing on the mixer and the device on your computer and that's it.

Switches and connection through jack socket terminals provide different send/return configurations:-

Send options:
1) Main Mix Left + Right (Post-fade)
2) Main Mix Left + Right (Pre-Fade)
3) Auxes 1-2
4) Auxes 3-4

Return options:
1) To Stereo 3 channel

ZED-24 features a responsive 3-band, swept mid frequency EQ design which utilises MusiQ - with optimised slope (or Q factor) for equalising individual instruments.

Based on the proven pre-amps from the hugely successful PA series, ZED-24 has DuoPre pre-amps, which use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the XLR input, the gain range is huge - 69dB of range to be exact - and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. Line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket, which has the great advantage of less noise when using the line input and also matching to a higher input impedance.

Notes: Gorgeous analogue goodness in this all-rounder, featuring overdrive, filter, envelope, LFO and a nice retro spring reverb among others processing options. Tons of character.

Supplier's notes:
Today's digital effects and plug-ins can create almost perfect room simulations. However, when it comes to characteristic and charismatic reverb, analogue effect-processors are yet to beat. The reverberating sound of a spring is so lively and unique that its sound is almost impossible to recreate in the digital domain. In addition to this, Retroverb Lancet is not just a spring reverberation system - it is an analogue multi-effects-processor. It offers overdrive, filtering, VCA, envelope and LFO to manipulate the spring sound and create different sounds like auto-wah, tremolo, distortion, delay, gater and of course reverb.

The typical spring reverb sound is generated by a Belton/Accutronics type 4 spring tank with 3 individual springs. It can be placed pre or post the VCF/VCA section and equalized by the Tone parameter.

The Crash function generates the popular thunder effect that occurs when kicking an amplifier with spring tank. You don't have to kick Retroverb Lancet you simply can achieve this effect by pressing the Crash button. It also can be triggered by a Gate voltage.

The multimode filter works as lowpass or highpass with a slope of 24 dB per octave or as bandpass with 12 dB per octave. It is followed by a voltage controlled amplifier. The filter and amplifier can be modulated individually by different sources.

in this all-rounder, featuring overdrive, filter, envelope, LFO and a nice retro spring reverb among others processing options. Tons of character. sources:

Envelope follower: the envelope follower converts the amplitude characteristic of the audio input signal into a control voltage.
Envelope generator: the envelope generator can be triggered by the input signal itself, a second audio signal or a gate voltage. Depending on the trigger source it works as Attack-Decay or as Attack-Sustain-Release envelope.
LFO: the LFO offers saw up and saw down, square, sine as well as sample&hold. Additionally it can use the envelope generators settings as waveform. It can oscillate freely or reset by different trigger sources.

The Retroverb Lancet also offers a CV/Pedal input which can be feed by external control voltages or can be used with expression pedals.
