ALLEN & HEATH ZED-10 (01) PDF DOCUMENT

Please adhere to the following safety instructions when operating your ALLEN & HEATH ZED-10:

Read instructions: Retain the safety and operating instructions for future reference. Follow all warnings and instructions printed in the User Guide.

Do not remove cover: Operate the console with its covers correctly fitted.

Power sources: Connect the console only to a mains power unit of the type described in the User Guide and marked on the rear panel. Use the provided power cord with a sealed mains plug appropriate for your local supply.

Power cord routing: Route the power cord so that it is not likely to be walked on, stretched, or pinched by items placed upon or against it.

Grounding: Do not defeat the grounding and polarisation means of the power cord plug. Do not remove or tamper with the ground connection in the power cord.

Water and moisture: To reduce the risk of fire or electric shock, do not expose the console to rain or moisture, or use it in damp or wet conditions. Do not place containers of liquids on it.

Ventilation: Do not obstruct the ventilation slots. If the console is operated in a rack unit or flightcase, ensure it is constructed to allow for adequate ventilation.

Heat and vibration: Do not locate the console in a place subject to excessive heat or direct sunlight. Locate it away from any equipment which produces heat or causes excessive vibration.

Servicing: Switch off the equipment and unplug the power cord immediately if it is exposed to moisture, liquid, or damaged in any way. Refer servicing to qualified technical personnel only.

Installation: Install the console according to the instructions in the User Guide. Do not connect the output of power amplifiers directly to the console. Use audio connectors and plugs only for their intended purpose.

The console is supplied with a moulded mains plug fitted to the AC mains power lead. If the mains plug needs to be replaced, the wires in the mains lead are coloured according to the following code. This appliance must be earthed.

The wire which is coloured Green and Yellow must be connected to the terminal in the plug which is marked with the letter E or with the Earth symbol.

The wire which is coloured Blue must be connected to the terminal in the plug which is marked with the letter N.

The wire which is coloured Brown must be connected to the terminal in the plug which is marked with the letter L.

Damage: To prevent damage to the controls and cosmetics, avoid placing heavy objects on the control surface, scratching the surface with sharp objects, or rough handling and vibration.

Environment: Protect from excessive dirt, dust, heat, and vibration when operating and storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and moisture. If the console becomes wet, switch it off and remove mains power immediately. Allow it to dry out thoroughly before using again.

Cleaning: Avoid the use of chemicals, abrasives, or solvents. The control panel is best cleaned with a soft brush and dry lint-free cloth. Faders, switches, and potentiometers are lubricated for life and the use of electrical lubricants is not recommended. Knobs may be removed for cleaning with a warm soapy solution; rinse and allow to dry fully before refitting.

Transporting: Protect the controls from damage during transit. Use adequate packing if you need to ship the unit.

Hearing: To avoid damage to your hearing, do not operate any sound system at an excessively high volume. This applies particularly to close-to-ear monitoring such as headphones and in-ear systems. Continued exposure to high volume sound can cause frequency selective or wide range hearing loss.

When you unbox your ALLEN & HEATH ZED-10, you should have received the following items:

1. ZED-10FX Mixer

2. Mains Lead (check that the correct mains plug is fitted for your region)

3. This User Guide

Mic Input Socket: This is a standard 3-Pin XLR socket for microphones. It is wired as Pin 1=Chassis, Pin 2=hot (+), Pin 3=Cold (-).

Line Input Jack Socket: This is a standard 1/4″ (6.25mm) jack socket for balanced or unbalanced line-level signals. It is wired as Tip=Hot(+), Ring=cold (-), Sleeve=Chassis. The Line input connects through the XLR input, so be aware that signals will be added together if both inputs are used simultaneously.

Gain Control: This adjusts the input amplifier’s gain. For the XLR Mic Input, the range is +10dB to +60dB. For the Line Input jack, the range is -10dB to +40dB.

100Hz Hi-pass Filter (HPF): This switch activates a filter to reduce low-frequency pop noise and rumble from microphone signals. It is a single pole (6dB per octave) filter with a corner frequency of 100Hz. It affects signals from both the Mic XLR and Line jack inputs.

The mono channels on the ALLEN & HEATH ZED-10 feature a 3-band equaliser:

HF EQ (High Frequency): This affects the higher audible frequencies. The corner frequency is at 12kHz and provides approximately +/-15dB of cut or boost.

MF EQ (Mid Frequency): This affects the middle of the audible frequency range. It is a swept-mid EQ, allowing you to select the center frequency you want to adjust using the ‘f’ knob (from 120Hz to 4kHz). The ‘MID’ knob then cuts or boosts this selected frequency. This is useful for cutting “boomy” frequencies (around 120Hz-250Hz) or boosting frequencies for microphone intelligibility (2kHz-3kHz).

LF EQ (Low Frequency): This affects the low end of the audio range. The corner frequency is at 80Hz and provides approximately +/-15dB of cut or boost.

FX send: This controls the level of signal sent from the channel to the internal effects processor. This is a post-level send, meaning its level is affected by the main channel Level control. Turning it fully clockwise provides +6dB of gain. There is no master level control for the FX bus.

AUX send: This controls the level of signal sent to the Auxiliary output. This is a pre-Level send, so it is independent of the main channel Level control. It has +6dB of gain fully clockwise. The Aux output has its own master level control in the master section.

PAN: The pan control adjusts how the mono signal is shared between the left and right main stereo outputs. In the center position, the signal is sent equally to both left and right. Panned fully left, the signal only goes to the left output, and vice-versa.

LEVEL: This rotary fader controls the amount of signal sent to the left & right main mix buses, the Record bus, and the FX send. The unity gain position is marked by “0”. Turning it fully clockwise provides +10dB of gain.

Record Switch: This switch sends the channel’s signal to a separate stereo bus called Record. The Pan and Level controls affect the signal sent to the Record bus. The main L-R mix signal is unaffected by this switch.

Listen Switch: This switch sends the channel’s signal to the headphones or monitor output for checking. The signal is taken after the EQ but before the Level control, allowing you to check the signal before adding it to the Mix or Record bus.

Mono channels 3 & 4 on the ALLEN & HEATH ZED-10 feature special Hi Z inputs for guitars and other instruments.

Hi Z Input: This is a standard 1/4″ (6.25mm) Jack socket for unbalanced line level or instrument pickup signals. The input impedance is extremely high (10Mohms), and a Class A FET (Field Effect Transistor) circuit emulates the valve/tube input of guitar amplifiers. This circuit provides a warm, 2nd harmonic character to the sound, with soft asymmetric overdrive characteristics.

Gain Boost: A recessed switch on the rear panel allows the Hi Z input to be boosted by 26dB. This is useful for instruments with weak pickups or when more overdrive is desired. When using the XLR input or normal line-level signals (like keyboards) on these channels, ensure this switch is in the OUT position.

ST-1b Inputs (RCA Phono): Use these standard RCA Phono sockets for unbalanced line-level stereo sources like CD players, sound modules, or MP3 players.

ST-1a Inputs (1/4″ Jack): Use these standard 1/4″ jack sockets for line-level stereo signals. Plugging into these jacks will override the signals from the ST-1b RCA inputs.

ST-1 Gain: This adjusts the input level for the ST1 channel, from off (maximum attenuation) to +15dB of gain. For low-level inputs like from MP3 players, turn it fully clockwise.

Stereo EQ: This is a 2-band equaliser.
HF: High frequency EQ with a corner frequency of 12kHz.
LF: Low frequency EQ with a corner frequency of 80Hz.
Both provide a maximum cut & boost of 15dB.

The FX send, AUX send, LEVEL, Record, and Listen controls on the stereo channel function similarly to those on the mono channels, with the following difference:

Balance (BAL): Instead of a Pan control, the stereo channel has a Balance control. It adjusts the relative level between the left and right signals being sent to the main mix. In the center position, the stereo image is preserved. Turning it towards L will reduce the level of the right signal, and vice versa.

ST-2 Input: The features of the ST-2 channel are the same as ST-1. The key difference is its input source. The USB audio input is connected by default. Plugging into the 1/4″ jack sockets will override the USB input. If you want to use the ST-2 channel for the USB input signal, make sure nothing is plugged into the jack sockets.

Important Note: If the ST-2 channel is not being used for USB playback or a stereo input, it is best to keep the level control turned down to prevent unwanted noise from the inactive USB device from entering the mix.

Record OUT: These are standard RCA phono sockets for the stereo line-level Record outputs. The signal source is determined by the USB OUT selector switches. They are useful for connecting to stereo recording devices or for stereo mix feeds.

Playback Input: These 1/4″ jack sockets can be used for additional unbalanced stereo sources. Plugging into these jacks overrides the USB audio input that normally feeds this input path.

USB OUT Source Selector Switches: These two switches select the signal source for both the USB audio output and the Record OUT sockets.
– With both switches up, the Main Mix is selected.
– You can select the Record Bus or the Aux-FX bus.
– If both the Record Bus and Aux-FX switches are pressed, the Record Bus switch will take priority.

Effects Type Selection LED: 8 green LEDs show which of the 16 effects is selected. The Bank LED determines whether you are selecting from effects 1-8 or 9-16.

Bank LED: When lit, it indicates that you are selecting an effect from 9 to 16 on the list.

SEL Buttons (Up/Down): These buttons select the type of effect. When the TAP button is held down, these buttons adjust the parameter of the selected effect. The more LEDs that illuminate during parameter adjustment, the greater the value or intensity.

TAP Button: For delay-based effects (types 1-5), you can tap this button in time with the music to set the delay tempo. If you hold the TAP button down, the SEL buttons become parameter adjusters.

FX to AUX Send control: This adds some of the effect signal to the Aux bus, which is useful for adding reverb to a monitor mix.

Effects Level: This controls the volume of the wet (effects) signal sent to the main stereo Mix and the Record bus.

Record Switch: Switches the wet (effects) signal to the stereo Record bus.

Listen Switch: Switches the wet (effects) signal to the headphones or monitor output for checking.

Restore Factory Defaults: To restore the parameter settings to factory defaults, hold down both SEL buttons while switching on the power to your ZED.

Main Mix Out XLR connectors: These are standard XLR outputs for the main stereo mix. A recessed switch on the rear panel reduces the level by 30dB if you need to submix these outputs into another mixer.

Main Mix Insert jack sockets: Standard 1/4″ jacks for inserting external processors across the main mix. Wired: Tip = send, Ring = return, Sleeve = Chassis.

Effects & Aux bus Outputs: Standard 1/4″ jacks. The FX out is the Effects bus output, used for external effects processors. A latching footswitch can also be connected here to mute the on-board FX. The AUX out is taken from after the AUX MIX master level control.

48v to Microphones: This switch applies industry standard 48v phantom power to all 4 microphone inputs for use with condenser microphones.

Monitor Level: Controls the volume of the stereo monitor outputs (RCA) from off to +10dB of gain.

Monitor Source switch: Allows the stereo monitor outputs to be sourced either from the headphone monitor selection or from the main stereo mix.

Aux Mix Level control: The master volume control for the Aux mix bus. Adjusts the level from off to +6dB gain.

Main Mix Level: This is the master volume control for the main stereo mix. Range is from off to +10dB of gain.

Stereo Meters: These 12-segment LED meters display the signals selected by the Phones Select switches, or the mono Listen signal (PFL) if activated on any channel.

PFL (Pre-Fade Listen) active LED: A red LED indicates that a Listen switch has been pressed on one of the channels. This overrides the Phones select source, sending the channel’s Listen signal to the headphones and the meters.

Headphones level: Controls the volume of the signal to the headphones.

Phones Source Selector switches: These switches choose what you hear on the headphones. With all switches up, you hear the main stereo Mix. You can also choose to listen to the Playback input, the Aux bus output, or the Record bus output. Pressing any channel’s Listen switch will override these selections.

Headphones Output: Standard 1/4″ jack socket wired Tip=Left, Ring=Right, Sleeve=Ground.

The ALLEN & HEATH ZED-10 is equipped with a stereo bi-directional USB 1.1 compliant audio CODEC, which is fully compliant with USB 2 ports.

1. Use a USB lead type A to B to connect the mixer to your computer.

2. The mixer uses standard Windows and MAC Core Audio Drivers, so there is no need to install special drivers. Your computer should automatically find and recognize the ZED USB device.

3. Select the ZED as your audio input/output device in your computer’s settings and within your audio software.

4. You will need audio software (DAW) on your computer to record and play back audio. On a basic level, you can use your computer’s media player to play audio through the ZED.

Important Note: If there seems to be no audio transfer between the computer and your ZED, or the level is very low, check the volume level setting of the Audio Device in your computer’s operating system. This may need to be set to the Maximum position.
