MX-508 Eight Input Stereo Mic/Line Mixer
Architects Specifications
MX-508
The unit shall be an eight input stereo mixer having separate
transformer-isolated balanced outputs for both left and right
channels. There shall be an electronically balanced mono-
summed output with separate front panel level control. Each
input channel shall have level and stereo-balance controls on one
concentric pot. Two aux sends on each channel must be provided
with one internally wired pre-fader /EQ and the other post fader/
EQ. The Pre/Post determination of the Aux sends shall be con-
figurable via circuit board jumper connections.
Each input channel shall have three-band equalization con-
trol with adjustable mid-band frequency sweep. The equaliza-
tion shall consist of high and low shelving points being fixed at
70Hz and 15kHz, and the mid-band peaking EQ control must be
adjustable between 140Hz and 8kHz. Each input channel shall
have 40dB of available attenuation and a switch for mic/line
selection on the front panel, as well as a 20dB mic input pad on
the rear panel. Each input channel shall have in/out insert points
on separate 1/4" phone connections, 1/4" phone connectors for
balanced line input sources, and XLR electronically-balanced con-
nectors for microphones (each input channel shall additionally
have the option of internal plug-in transformers). Phantom power
of +48VDC on each input must be available via a front panel
switch. There shall be two Master Aux Sends provided and two
panable Master Aux Returns (one stereo and one mono). There
shall be an additional stereo CD/Tape input on RCA jacks with
level control to the Mains or Aux 1. Separate stereo RCA tape
outputs must also be provided. There shall be Pre-Master Sub In/
Out patch points for left and right and Aux Sub outputs on 1/4"
phone jacks for linking other mixers. A selectable Headphone
output with level control to monitor either Left and Right or Aux
1 and 2 must be provided on the front panel. Overall gain avail-
able from Mic Input to Master Output shall be 84dB, and the
Output level shall be +24dBm into 600 ohms. The mixer unit
shall be no higher than three rack spaces and must be fully cov-
ered under a five year warranty. The mixer must be manufac-
tured in America, with a shipping weight of 20 pounds.
The mixer shall be the model MX-508, manufactured by Ashly
Audio, Inc. No other unit shall be acceptable unless data submit-
ted from an independent test laboratory verifies that the above
size/performance specifications are met.
