MX-206
The unit shall be a six input stereo micro-
phone mixer with TRS stereo outputs as
well as a transformer-isolated +24 dBm ,
600 ohm balanced XLR mono output. There
shall be +48 volts of phantom power avail-
able for condenser microphones, with gradual
power-up and down of this phantom power to
eliminate any transient spikes. Total voltage
gain measured from each microphone input
to the Master Output shall be a minimum of
84dB. Each of the six microphone channels
shall have 40dB of adjustable gain via a front
panel 3 position slide switch. Each input shall
also have a 20dB pad switch on the rear of
the unit, making a total of 60dB of possible
gain/attenuation. Each channel shall have a
continuously variable pan control. There shall
be a peak Clip LED indicator on each input
channel which shall illuminate when the input
is 3dB below true clipping, and another Clip
indicator on the output of the mixer which
shall illuminate when the output is within 3dB
of actual clipping. Two 6-segment LED meters
must be provided to monitor the mixer output,
calibrated for 0 VU to equal +4 dbu. There
shall be a separate stereo aux input with front
panel level control, having rear panel con-
nection via RCA phono jacks. There shall also
be a separate stereo aux output available on
the rear panel with access via RCA phono
jacks. Distortion shall be less than 0.02 %
Total Harmonic Distortion at +20dBu (20Hz to
20kHz) and less than 0.05% Intermodulation
Distortion (SMPTE) at +20 dBu (input switch
at -40dB). Hum and Noise shall be less than
-100dBu residual output noise when all levels
are set at minimum. Frequency Response shall
be +0/-.5dB, 20 Hz-20 kHz. Crosstalk of the
unit shall be less than -60dB when measuring
adjacent inputs or input to output at 20kHz.
Dimensions of the model shall be 19” wide
x 1.75” high x 6.6” deep. The mixer shall be
made in America, with a 10 pound shipping
weight.
The mixer shall be the model MX-206,
manufactured by Ashly Audio, Inc. of Webster,
New York. No other unit shall be acceptable
unless data submitted from an independent
test laboratory verifies that the above specifi-
cations are met.
