A&E Specifications 
The  mixer  shall  be  a  compact  and  portable  analog  mixer  with  4 
mono  and  2  stereo  input  channels  mixing  to  a  stereo  Main  Mix 
output. The mixer shall weigh no more than 2.31kg (5.1lbs). 
Each mono input channel shall have an XLR Microphone connector 
and Line level quarter-inch jack  connector and shall be equipped 
with High Pass Filter and 3-band equaliser circuit 
Stereo input channels shall use quarter-inch jack connectors, and 
shall have a fixed 2-band EQ. 
All  XLR  Microphone  inputs  shall  have  the  ability  to  power 
Condenser  Microphones  requiring  48  Volt  Phantom  Power.  This 
shall be switchable and have a red LED to indicate activation. 
There shall be two high-impedance jack inputs on mono channels, 
which can  handle a  normal line level or a low level input directly 
from  a  guitar pickup,  allowing  instruments  such  as  guitars  to  be 
plugged straight into the mixer without the need for a DI box. There 
shall be an additional two jack inputs for normal line level signals, 
activated via a pad button. 
XLR Mic input characteristics shall conform to a Gain Min/Max of 
6dB to 60dB with a maximum Input Level of 13dBu. 
Quarter-inch jack Line input characteristics shall conform to a Gain 
Min/Max of -14dB to 40dB with a maximum Input Level of 18dBu. 
The mixer shall have on-board effects which can be independently 
applied to each input channel. In addition there shall be an effects 
out on a quarter-inch jack connector. 
The  mixer  shall  have  a  4in/4out  USB  Audio  Interface  which  will 
allow  for  a  total  channel  count  of  ten.  The  audio  interface  shall 
operate at 24 bit/96kHz as standard, be class compliant for Mac and 
iOS devices and be compatible with Windows. 
The mixer surface shall include independent rotary control for each 
input  channels  gain,  level  and  mix.  Each  channel  should  have  an 
individual Pan control and a [PFL] switch to route to the headphone 
output. An LED shall indicate when a [PFL] channel is active. 
The Headphone output  should use a quarter-inch  jack connector 
with a rotary to control output level. 
The L&R outputs shall have XLR connectors and will be controlled 
via a mix output fader. Level indication shall be via a stereo eight 
segment LED display. 
There shall be a  stereo  monitor output on RCA connectors and a 
separate AUX output on quarter inch jack socket. 
It shall have a built in power supply accepting AC mains voltages of 
100~240V,  50/60  Hz,  12W  max via an  earthed  3-pin IEC C6  male 
connector mounted on the rear chassis. 
A switch shall be provided near the mains inlet to isolate the mixer 
from the incoming mains supply. 
Recommended operating temperature for the mixer shall be 0 to 
35 degrees Celsius. 
The unit shall be the Allen & Heath ZEDi-10FX.
