Controls & Connections
1. CHANNEL SECTION
(1) MIC INPUT
This electronically balanced XLR input is designed to accept
signals from any balanced or unbalanced low impedance (Low Z)
microphone. The XLR jack is configured for: Pin1 = ground,
Pin2 = positive (+), Pin3 = negative (-).
(2) LINE INPUT
This
1
⁄4” input is designed to accept balanced or unbalanced line-
level signals such as those from keyboards, drum machines, or
samplers. If a balanced signal is to be connected to the line input,
then a
1
⁄4” TRS (stereo) phone plug should be wired for:
Tip = positive (+), Ring = negative (-), Sleeve = ground.
Unbalanced signals should use a typical ¼” TS plug.
[Note: Only the Mic or the Line input of a given channel should be
connected at one time. Do not connect both at the same time].
(3) LOW CUT FILTER
Use this Low-Cut (high-pass) filter (18 dB/octave, -3 dB at 110Hz)
for reducing floor rumble, popping, breathing noises, woolly
bottom end, and to tighten up channels in a mix, etc. It is most
effective when used carefully in conjunction with the Equalizer
Controls(6).
(4) GAIN CONTROL
The Gain control adjusts the input sensitivity of the mic and
line inputs on each channel. This control can be adjusted to
accommodate input signals from a wide variety of sources, from
the high outputs of keyboards or drum machines to the small
signal outputs of microphones. The best balance of S/N and
dynamic range will be achieved if you adjust the Gain control on
each channel separately so that the maximum level signal can
be input without distortion. While speaking, singing, or playing
an instrument at maximum performance level, increase the Gain
control until the Peak LED(5) flashes, then turn down the Gain
control until the flashing stops.
(5) PEAK LED INDICATOR
The Peak LED illuminates when a channel input is overloading.
It detects the peak level after the Equalizer Controls(6) and will
light just before clipping to warn that the signal is approaching
overload. You do not want the Peak LED to light except very
intermittently. If it lights persistently, reduce the Gain Control(4).
