WARNING: This equipment must be earthed.

Read instructions: Retain these safety and operating instructions for future reference. Adhere to all warnings printed here and on the console. Follow the operating instructions printed in this User Guide.

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

Power sources: Connect the console to a mains power unit only of the type described in this User Guide and marked on the rear panel. Use the power cord with a sealed mains plug appropriate for your local mains supply as provided with the console. If the provided plug does not fit into your outlet consult your service agent for assistance.

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 which might spill into any openings.

Ventilation: Do not obstruct the ventilation slots or position the console where the air flow required for ventilation is impeded. If the console is to be operated in a rack unit or flightcase ensure that it is constructed to allow adequate ventilation.

Heat and vibration: Do not locate the console in a place subject to excessive heat or direct sunlight as this could be a fire hazard. Locate the console 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, spilled liquid, objects fallen into the openings, the power cord or plug become damaged, during lightening storms, or if smoke, odour or noise is noticed. Refer servicing to qualified technical personnel only.

Installation: Install the console in accordance with the instructions printed in this 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 has to be replaced, the wires in the mains lead are coloured in accordance with the following code:

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. This appliance must be earthed.

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.

Ensure that these colour codes are followed carefully in the event of the plug being changed.

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 off and remove mains power immediately. Allow 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. The faders, switches and potentiometers are lubricated for life. The use of electrical lubricants on these parts is not recommended. The fader and potentiometer knobs may be removed for cleaning with a warm soapy solution. Rinse and allow to dry fully before refitting them.

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 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 unpack your ALLEN & HEATH ZED-10FX, check that you have received the following items:

1. ZED-10FX Mixer

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

3. This User Guide!

Mic Input Socket: Standard 3-Pin XLR socket wired as Pin 1=Chassis, Pin 2=hot (+), Pin 3=Cold (-).

Line Input Jack Socket: Standard 1/4″ (6.25mm) Jack socket for balanced or unbalanced line level signals. Wired Tip=Hot(+), Ring=cold (-), Sleeve=Chassis. The Line input connects to the XLR input through a circuit, so be aware that the two signals will add together if both inputs are plugged in simultaneously.

Gain Control: This adjusts the gain of the input amplifier to match the signal level of the source. The gain is varied from +10dB to +60dB for signals plugged in to the XLR socket (Mic Input) and -10dB to +40dB for signals plugged into the Line input jack.

100Hz Hi-pass Filter: The Hi-pass filter is used for reducing pop noise and rumble from microphone signals. It is a single pole (6dB per octave) filter with a corner frequency set at 100Hz. The filter affects signals from both Mic XLR and Line jack socket.

HF EQ: The HF (High Frequency) equaliser affects the frequency response of the higher audible frequencies. The corner frequency of 12kHz is around 3dB from the maximum cut or boost of the circuit.

MF EQ: The MF (Mid Frequency) equaliser affects the middle of the audible frequency range. The frequency graduations on the sweep control are the centre frequencies of the EQ. The range covers “boomy” frequencies around 120Hz to 250Hz, or allows a lift at 2 to 3kHz for microphone intelligibility.

LF EQ: The LF (Low Frequency) equaliser affects the response at the low end of the audio range. The corner frequency is 80Hz.

FX send: This controls the level of signal that is sent to the effects processor from the channel. The signal is post-level, meaning it is affected by the channel Level control. The send control has 6dB gain fully clockwise. There is no master level control for the FX bus.

AUX send: Controls the level of signal sent to the Auxiliary output from the channel. The signal is sourced pre-Level, so it is independent of the level being sent to the main L-R Mix. The send control has +6dB gain fully clockwise. There is a master level control for the Aux output.

PAN: The pan control adjusts how the signal from the mono input channel is shared between the left and right stereo buses. Set to the mid position, equal amounts of signal are fed to left and right.

LEVEL: The rotary Level or fader controls the amount of signal to the left & right buses, Record bus and to the FX send control. There is 10dB of gain fully clockwise and the unity gain position is marked by “0”.

Record Switch: Switches the channel signal to a separate stereo bus called Record. The Pan and Level controls affect the Record signal, while the channel Mix L-R signal remains unaffected by this switch.

Listen Switch: Switches the channel signal to the headphones or monitor output circuit for checking the channel signal. It takes the signal after the EQ but before the Level control, so you can check the signal before adding it to Mix or Record.

The main difference between mono inputs 1-2 and 3-4 is the Hi Z inputs for guitars or other instruments.

Hi Z input: This is a standard 1/4″ (6.25mm) Jack socket for unbalanced line level signals or instrument pickups. The input impedance is extremely high (10Mohms) and a FET (Field Effect Transistor) running in Class A mode emulates the type of circuits used in valve guitar combos or head amplifiers. The input circuit has soft asymmetric overdrive characteristics, giving a warm 2nd harmonic character to the sound if required.

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 where more overdrive is required. When the XLR is being used or for normal line level signals (like keyboards), make sure the switch is in the OUT position.

Note: The Hi Z input connects to the XLR input through a circuit, so the two signals will add together if both inputs are plugged in simultaneously.

Stereo Input Channel 1 (ST1):

ST-1b Inputs: Standard RCA Phono sockets for unbalanced line level stereo sources like CD or MP3 players.

ST-1a Inputs: Standard 1/4″ jack sockets for line level stereo signals. Plugging into ST1a will override the signals from ST1b.

ST-1 Gain: Adjusts the input level from off (maximum attenuation) to +15dB gain.

Stereo EQ: A 2-band equaliser with corner frequencies of 12kHz for HF and 80Hz for LF, with a maximum cut & boost of 15dB.

Stereo Input Channel 2 (ST2):

ST-2 Input: The USB audio input is connected through the break contacts of the standard 1/4″ jack sockets. Plugging into these jacks will override the USB input. If you want to use the ST-2 channel for the USB input signal, ensure nothing is plugged into the jack sockets. The rest of the features (Gain, EQ, sends, etc.) are the same as for ST-1.

Important Note: If the ST-2 channel is not being used for USB playback or stereo input it is best to keep the level controls turned down so that unwanted noise from the inactive USB device is not passed to the mix.

Controls for both ST1 and ST2 (FX, AUX, Balance, Level, Record, Listen): These controls function similarly to their mono channel counterparts but operate on a stereo signal. The ‘Balance’ control replaces the ‘Pan’ control and adjusts the relative level between the left and right stereo signals as they are sent to the stereo buses.

Effects Type Selection LED: 8 Green LEDs show one of 16 effects types available. If the Bank LED is off, the green LEDs will show one of 1 to 8. If the Bank LED is on, the green LEDs show which of effects types 9 to 16 is selected. For effects types 1 to 5, the green LED will blink in time with the tempo of the delay time. The green LEDs also display the level of the parameter adjustment when the TAP button is held down.

Bank LED: Illuminates when one of the effects types 9 to 16 is selected.

SEL Buttons: These buttons select the type of effect. They also adjust the parameter of the selected effect when the TAP button is held down.

TAP Button: If one of effects types 1 to 5 is selected, the TAP button can be used for adjusting the tempo of the delay. If the TAP button is held down, the SEL buttons become parameter adjust buttons to increase or decrease the level of the parameter assigned to the selected effect.

FX to AUX Send control: This adds some of the effect to the Aux bus, allowing a performer using a monitor to hear their voice with some reverb added, for example.

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

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

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

To restore the parameter settings to the factory defaults, hold down both SEL buttons whilst switching on the power to your ZED.

The ZED Effects Processor has 16 presets. Each preset has a parameter adjust control which is matched to the preset. In general, when adjusting the effect parameter, the more LEDs that are illuminated, the more intense the effect or higher the parameter value.

Main Mix Out XLR connectors: Standard XLR output connectors for the main stereo mix. A recessed switch on the rear panel reduces the level by 30dB if it is required to submix these outputs into the XLR inputs of another mixer.

Main Mix Insert jack sockets: Standard 1/4″ jack sockets (Tip = send, Ring = return) for inserting external processors into the main mix.

Effects & Aux bus Outputs: 1/4″ jack sockets for the Effects bus output and the Auxiliary bus output.

48v to Microphones: Switches 48v phantom power to all 4 microphone inputs for use with condenser microphones.

Monitor Level: Controls the volume of the stereo monitor outputs (RCA phonos) 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 from off to +6dB gain.

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

Stereo Meters: 12 Segment LED meters display the signals selected by the Phones Select switches, or the mono Listen signal (PFL) if activated.

PFL (Pre-Fade Listen) active LED: A red LED indicates a Listen switch has been pressed on one of the channels, overriding the Phones select source.

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

Phones Source Selector switches: Allows you to choose what you hear on the headphones: Main Mix, Playback input, Aux bus output, or Record bus output.

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

The ALLEN & HEATH ZED-10FX is equipped with a stereo bi-directional USB 1.1 compliant audio CODEC that is fully compliant with USB 2 ports and uses standard Windows and MAC Core Audio Drivers.

Simply plug a USB lead (type A to B) from the mixer to your computer. Your computer will find the ZED USB device and be able to transfer audio to and from it.

You will need audio software on your computer to store and play back recordings. On a basic level, your computer’s media player can play audio straight to the ZED device.

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

Record OUT: Standard RCA phono sockets for the stereo line level Record outputs. These are sourced from the USB out selector switches. Useful for connecting to stereo recording devices.

Playback Input: Standard 1/4″ jack sockets for unbalanced line level inputs. Can be used for additional stereo sources like CD players. The USB audio input is connected through the break contacts of these inputs, so plugging into the jack sockets overrides the USB input.

USB OUT Source selector switches: These switches select the signal source for both the USB audio output and the Record output.

With both switches up, the Main Mix is selected.

You can also select the Aux-FX bus or the Record Bus.

The Record Bus switch will override the Aux-FX switch if both are pressed.
