(1) CHANNEL 1-3 COMBO XLR / 1/4' INPUT
The XLR mic inputs are an electronically balanced XLR
type designed to accept mic level signals from any
balanced or unbalanced low impedance (Low Z)
microphone. The XLR jacks are configured for: Pin1 =
ground, Pin2 = positive (+), Pin3 = negative (-). The XLR
jacks have 15VDC phantom power applied to Pin2 and 3
for powering condenser microphones.
The 1/4" mono line inputs are designed to accept
unbalanced line level signals such as those from
keyboards, drum machines, or samplers.
(2) CHANNEL 4 XLR & 1/4" STEREO/MONO INPUTS
The XLR input is balanced, designed to accept mic level
signals, and has 15VDC phantom power. The Left and
Right 1/4" line inputs are for connecting stereo line level
audio signals or only the Left/Mono jack can be used for
connecting mono signals. The XLR input is defeated when
either of the 1/4" inputs are used.
(3) CHANNEL 5 STEREO RCA INPUTS
The stereo RCA line level inputs can be used for
connecting CD players, Tape Decks, and other audio
equipment with line level outputs.
(4) MONO / STEREO MODE
When the Mono/Stereo button is out (stereo mode) the Left
RCA Aux In is sent to the Left Speaker and Right RCA Aux
In is sent to the Right Speaker. When the button is
depressed (Stereo mode), both L and R RCA input signals
are mixed and sent to both speakers.
(5) EFF SEND CONTROL
The EFF SEND control adjusts the level of signal sent by
each channel to the internal DSP (Digital Sound
Processor). The signal sent is mono, post-Treble/Bass and
will be affected by the CHANNEL FADER (8) setting.
(6) TREBLE CONTROL
Turn to the right to boost high frequencies, adding
crispness too percussion from drum machines, cymbals
and synths. Turn to the left to cut these frequencies,
reducing sibilance or hiss. The control has a shelving
response giving +/-10dB of boost or cut at 10kHz.
(7) BASS CONTROL
The bass control shelving response gives 10dB of boost or
cut at 100Hz. Add warmth to vocals or extra punch to
guitars, drums and synths by turning to the right. Turn to
the left to reduce stage rumble, hum or to improve a mushy
sound.
(8) CHANNEL FADER
The channel faders determine the output signal level to the
Master Mix bus. They offer a smooth logarithmic taper
more often associated with much more expensive consoles
for optimum control of the signal.
