Select Bar Graph Readout; The Ground Lift Jumper; Rack The Mixer - Intelix 4001 VC User Manual

Intelix VC Series Mic/Line Mixer User Manual
If during ordinary use one or more inputs occasionally exceed the maximum input levels set
up during the set up procedure (i.e., the red (+12 dB) LED on the bar graph meter occasion-
ally lights), press the Output Limiter Switch to the on position.
If during ordinary use one or more inputs continually exceed the maximum level (i.e., the red
LED continually lights), the input volume must be reset; return to the set up procedure as
defined in Section 3.
Note: If the amplifier/speaker combination is such that the speakers can be overdriven to
failure, always operate the mixer with the Output Limit Switch in the on position.

5.2.3 Select bar graph readout

The LED Bar Graph Output Meter may be set to register either the peak or average level
of the output audio signal. To do so requires opening the chassis. The locations of the jumpers
for this are shown in section 6.0. The factory setting is to the average level; i.e., the Average
Bar Graph Jumper (J 3) is in place. To select peak level, move the jumper from J3 to the
Peak Bar Graph Jumper (J 2) instead. For the meter to operate, a jumper must be in one of
these two positions. Never place jumpers in both positions.

5.2.4 The ground lift jumper

The ground lift jumper on all VC series mixers is a feature designed to help prevent ground
loops. When jumper J4 is present, it grounds the mixer to its chassis. If the mixer is installed
in a non-metal cabinet, the jumper is left in place. When the mixer is installed in a grounded
metal rack frame, use a needle-nose pliers to remove the jumper via the ground lift jumper
access.

5.2.5 Rack the mixer

Install the mixer in the rack or other cabinet where it will be when in use. The mixer should be
located away from heat sources, including other electronic components which generate a large
amount of heat, such as amplifiers. Verify the unit is well-secured.
