Allen & Heath 10 ZED-4 BUS User Guide

INTRODUCTION TO THE ZED-4 BUS MIXERS

A Technical Overview:

The Allen & Heath ZED-4 mixer has been carefully and lovingly designed in the beautiful county of Cornwall in the UK and is manufactured alongside a wide range of professional audio mixing consoles. Many of the components used in ZED are exactly the same as in the larger Allen & Heath products and the construction methods are also very similar — utilising individual vertically mounted channel circuit boards with each rotary control fixed with a metal nut to the front panel. This provides a very robust product that will resist damage and give years of reliable use. It also makes servicing much easier should it be required, with the ability to remove one particular channel from the mixer at a time, or easily change a fader.

The audio circuitry is based on years of continual development and refinement, the performance of all the elements within the mixer scrutinised and perfected to ensure the very best sound quality possible.

Mic/Line Pre-amps:

Based on the pre-amps from the PA series, the ZED series pre-amps 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. There is no “pad” switch, or pad circuit — line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket. This has the great advantage of lower noise when using the line input. (It is common to attenuate line level signals, the amplify them back up again which can give more noise or hiss).

EQ:

The ZED-4 series mixers are equipped with a 4-band equaliser circuit on each input, based closely on the acclaimed GL2400 EQ. The frequency and response of each has been carefully chosen to give the maximum performance when using the EQ on a variety of sources.

AUX system:

Six auxiliary sends are provided, two pre-fade, two post fade, and two switched pre or post fade. The Aux master level controls are grouped nicely together in the master section and have AFL (after fade listen) switches for monitoring.

Groups:

The four sub-groups can be used for easy control of groups of inputs, or for applying signal processing such as compression to groups of signals using the Group Insert connector. The groups have individual outputs and can also be sub-mixed to the main L-R and Mono mixes.

Main Mix:

In addition to the main L-R stereo bus, there is a Mono bus which can be routed to individually, ideal for feeding low frequency speaker systems, or creating a mono PA mix.

Mono and Stereo Channels:

The ZED-420, 428 and 436 models have a full complement of 16, 24 and 32 mono inputs respectively, plus two stereo channels, maximising the number of inputs you get. The Stereo channels are dual, so you can get 4 stereo inputs to mix before you need to use any mono channels.

USB:

Getting audio to and from a computer easily is now a common requirement for live sound and music production. The way we have implemented this on ZED 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, select the USB routing on the mixer and the device on your computer and that’s it! Quality audio to and from your PC or MAC.

As you can tell, we’re very proud of this product we hope you like it too!

Gain Control

6

This adjusts the gain of the input amplifier to match the signal level of the input. The gain is varied from –6dB (attenuation) to +63dB for signals plugged in to the xlr socket (Mic Input) and –10dB to +26dB for signals plugged into the Line input jack.

100Hz Hi-pass Filter

The Hi-pass filter is used for reducing pop noise and rum-

7

ble from microphone signals. It is a 2-pole (12dB per octave) filter with a corner frequency set at 100Hz. The filter affects signals from both Mic XLR and Line jack socket.

EQ IN

The EQ IN switch enables the equaliser when pushed in. The EQ is bypassed when the switch is in its up position.

Auxes 1 & 2

Each of these controls sends a signal to an auxiliary bus. The signal is sourced pre-fade which means that the level is independent of, and unaffected by the fader. Auxes 1 & 2 are primarily used for foldback monitoring purposes, as the fader does not affect the level. They can also be used as feeds for recording and are available sources to the USB interface for this purpose. These sends are affected by the Mute switch, so muting the channel will also mute the Aux sends. The control varies the signal level to the bus from off (fully attenuated) to +6dB, with unity gain at the arrow. There are master level controls for all of the Aux outputs situated in the master section of the mixer.

Auxes 3 & 4

These are switched pre or post-fade so they can be used as either monitor sends or effects sends.

The pan control adjusts how the signal from the mono input channel is shared between the left and right buses and subsequently the main stereo outputs, similarly to pairs of Groups. Set to the mid position, equal amounts of signal are fed to left and right, with pan set to L, none is sent to the Right bus.

Mute Switch

This mutes or cuts the signal to the buses and the Direct Out. A rectangular LED illuminates to show the Mute switch is pressed.

PFL Switch

The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL bus and subsequently to the headphones and the main L R meters. Used for checking the audio signal before raising the fader or un-muting the channel.

Signal & PK! LED

The Signal LED illuminates dimly at a threshold of –16dB nominal level and gets brighter with higher level signal. The source for the signal & peak LED’s is just after the EQ IN switch.

The PK! LED illuminates when the signal just after the EQ IN switch is within 5dB of clipping.

The routing switches connect the post-fade signal to the mix buses via the pan control for the main LR bus and the group buses. For minimum noise from the mix bus summing amplifier, leave the switches in their up positions if the channel signal is not required on the bus.

Fader

The 100mm fader affects the level of the channel signal to the left & right, mono and group buses and Auxes 5 & 6. Also Auxes 3 & 4 if switched to post-fade. There is 10dB of gain at the top and the unity gain position is marked by “0”.

USB Audio Interface

The ZED is equipped with a stereo bi-directional USB 1.1 compliant audio CODEC. It is fully compliant with USB 2 ports and uses standard Windows and MAC Core Audio Drivers. In other words, plug it in and your computer will find it and be able to transfer audio to and from the ZED USB device. You will need some form of audio software running on your computer to be able to record and play back what you record, but on a basic level, you can use your computers media player to play straight to the ZED device. Just a couple of points to look out for:

1. When you plug in your ZED USB interface to your computer, check the device volume in:

Control Panel\Sounds & Audio Devices\Volume

If the volume is not fully up like this…...

Then drag it fully up like this…...

Then click Apply

2.

If you want to reduce latency (delay) there are some different drivers available for your operating system. Please check the Allen & Heath website www.allen-heath.com for details and links to third party companies able to supply appropriate drivers for your operating system.

SONAR LE Installation.

Put disk into CD or DVD ROM drive and follow instructions on screen!

SONAR LE Audio Configuration with ZED.

To configure your SONAR LE software to communicate audio to and from your ZED mixing console, follow the sequence below. Ensure the ZED mixing console is powered on. Connect the USB lead from the computer to the USB port on ZED.

First check that your computer has recognised the connection of the ZED USB device by clicking Settings/Control Panel/Sounds and Audio Devices.

The device name should be USB Audio CODEC (ensure there are no other external audio devices attached to the computer). Also ensure the Device Volume is set to High. This can default to the middle during connection which means very low volume from the USB device, so it’s worth checking the first few times you connect.

The properties window should look like this:

It is also a good idea to select “No Sounds” in the Sounds window.

Allen & Heath 29 ZED-4 BUS User Guide

Next, fire up SONAR LE.

Click Options/Audio and click on the Drivers tab.

The Input drivers are the audio sources to the computer, here we have enabled the USB Audio Device which is the ZED mixing console USB device, and disabled the audio from the soundcard in the pc. So the computer is set up to receive audio from ZED.

The Output Drivers are the audio outputs from the computer. Here you can see that the pc soundcard has 4 stereo outputs (all disabled) and the software has located the USB Audio Device which is ZED. Tick to enable it.

You will now be able to select your ZED USB left & right outputs as inputs to SONAR LE and be able to send audio to your ZED from SONAR outputs.

In order to show how to select inputs to SONAR tracks, here is a basic Cakewalk project (.cwp). This is created by clicking File/New/Normal and then inserting a second audio track by clicking Insert/Audio Track from the main toolbar. Click on the I/O tab near the bottom of the window, then click the expand buttons in the audio track panes. The tracks 1 & 2 have been re-named ZED Left and ZED Right by double clicking the name field. Click the I and the O fields to select inputs and outputs for the track. Here we have selected the USB Left signal to go to Track 1 (ZED Left) and the USB Right signal to go to track 2 (ZED Right), panned them accordingly and selected the track outputs to be the Master Bus.

If audio is present, click the Input Echo buttons (lit up yellow here) to monitor the signals on the Master Bus.

The output for the Master Bus is displayed in the field marked “O” in the Master Bus pane below the input tracks. You can see here it says USB Audio Device, which is the ZED USB input. SONAR will configure this automatically if there is only one output device enabled in the Output Drivers Options window (above).

You should now be able to send audio to and from your ZED mixing console using SONAR LE.

To test this, let’s do a recording….

Allen & Heath 30 ZED-4 BUS User Guide

To record the audio on tracks 1 & 2, click the R buttons so they light up red, then the record button (circle) on the transport controls on the top icon toolbar. (Or select larger transport controls from Views). The audio wave profile will show in the track panes. Click stop (Square) when finished.

To listen to the recording, click rewind, then de-select the input echo buttons (to the right of the R buttons. Also disarm the tracks by deselecting the R buttons.

Click Play (or spacebar) and the recorded audio should play to the USB port on your ZED mixing console where you can select USB return to Playback or to the ST3 input.

You can use SONAR LE and your ZED mixer together in many ways, for example straightforward recording of a stereo mix, recording tracks individually to build up a song, or sending a postfade mix from ZED and inserting an effects plug-in from SONAR LE, returning the post-effects signal to the mix in ZED.

It is a very versatile combination and we hope you find it a creative and enjoyable product partnership.
