LX-308B
The unit shall be an eight channel stereo
line-level mixer in a one rack space metal
chassis. Each channel shall have a pair of
balanced 1/4” input jacks with level and pan
controls on the front panel. Channels 1 and
2 shall be switchable to accommodate either
microphone or line level sources. An input on/
off switch with a LED status indicator shall be
provided for independent channel muting.
The unit shall have separate Left and Right
clip indicators to monitor all internal amplifiers
for any possible overload conditions. There
shall be Left and Right outputs on 1/4” TRS
phone jacks which can be used as balanced or
unbalanced. In addition, there shall also be an
independent Mono summed output on a sepa-
rate 1/4’ TRS jack. Left/Right level control,
variable panning, and a master stereo mute
switch must be provided on the front panel, as
well as an overall adjustment for the indepen-
dent Mono summed output.
There shall be a stereo headphone jack with
separate level control located on the front
panel of the unit. Pre-Master sub inputs and
outputs for linking with other mixers must be
located on the rear panel. The unit shall have
the ability to operate as an eight input stereo
or a sixteen input mono mixer by patching
cables accordingly.
The mixer shall provide an unity gain signal
path when all level controls are set at twelve
o’clock.
Distortion shall be less than 0. 02 % Total
Harmonic Distortion at +20dBu (20Hz to
20kHz) and less than 0. 01% Intermodulation
Distortion (SMPTE) at +100dBu (20Hz to
20kHz.) Hum and Noise shall be less than -
98 dBu residual output noise when all levels
are set at minimum, and less than -90dBu
at nominal (unity) gain. Frequency Response
shall be ± 0.2dB, 20 Hz-20 kHz. Voltage gain
of the mixer shall be 25dB ± 1dB when mea-
sured from channel input to master output
when levels are set at maximum. Voltage gain
when channel one or two are in mic posi-
tion shall measure 56dB ± 1dB at the master
outputs. Crosstalk of the unit shall be less
than -80 dB when measuring adjacent inputs
or input to output at 1kHz. Dimensions of
the model shall be 19” wide x 1. 75” high x
8. 0” deep. The shipping weight shall be 13
pounds. The mixer must be made in America
and covered under a full Five Year warranty.
The mixer shall be the model LX-308B, manu-
factured by Ashly Audio, Inc. of Webster, New
York. No other unit shall be acceptable unless
data submitted from an independent test labo-
ratory verifies that the above specifications
are fully met or exceeded.
