The RX-31C is an eight input, one program output and one line output mixer,
designed especially for sound reinforcement systems in auditoriums, churches
and similar applications. Each input channel is transformer isolated and accepts
either a low impedance microphone or a high level source. A MIC/LINE selector
switch on each input channel permits selection of the type of source. A phantom
ON/OFF switch on each input channel applies 48V DC phantom power for con-
denser microphones. An input TRIM control on each input channel provides 30dB
of gain adjustment prior to the main channel fader. A channel ON/OFF slide
switch on each input channel connects or disconnects the input signal to the mix-
ing bus. The adjacent green LED illuminates when the channel is "on". An LED
bar graph peak meter with 12 sections calibrated in 3dB steps responds instant-
ly to the program output level. Also featured is a 5 band (peaking) equalizer with
rotary controls plus switchable high pass/low pass filters for reducing wind and
scratch noise. A headphone output enables the operator to audition each input
channel, AUX input, program output or line output, depending on the position of
the phones selector switch. With an optional bracket, the RX-31C is usable in a
rack-mounted configuration.
