Unbalanced Source to Balanced Input
For an unbalanced source device, the
drawing at right shows an alternative
wiring method. Because the grounding of
the minus input is not to the mixer ground,
this method does not provide the +6 dB
boost. Ground current and noise rejection
is good.

3.7 Fine Tuning

This section details several 8002MCB features which aid in fine tuning the audio signal.

3.7.1 Low cut switch

The low cut switch helps eliminate low frequency noise (signals of 150 Hz and below), such
as the back-ground rumble from ventilation systems, and is used primarily with mic-level
inputs. It is particularly effective when used in conjunction with handheld microphones.

3.7.2 Phantom power

The phantom power switch powers condenser (capacitor) mics through the microphone cable.
Depressing the phantom power button activates all channels set to mic-level simultaneously.
All 8002MCB models support 30VDC phantom power.

3.7.3 Ground lift jumper

The ground lift jumper (J19) is designed to help prevent ground loops. When the jumper is
present, mixer electronics are grounded to the chassis. If the mixer is installed in a non-metal
cabinet, the jumper should be left in place. The jumper should be removed when the mixer is
installed in a grounded metal rack frame, or when there is obvious ground loop noise in the
output. The jumper may be removed with a needlenose pliers.

3.7.4 Compressor/limiter

The compressor/limiter is a dynamic range controller that is used to compensate for signals
that may sound unnatural or cause audible distortion, as indicated by the bar graph output
meter occasionally exceeding +12 VU (red). The compressor/limiter is activated by pressing
the main output compressor/limiter switch.
The compressor is used to slightly reduce the dynamic range of a signal. This effect is per-
ceived to quiet loud sounds and boost quiet sounds. The compressor smooths transients.
The limiter is used to prevent a signal from exceeding a certain level. This function guards
against amplifier or recording level overloads.
