6 ICON 300/700
REAR PANEL DESCRIPTION
6. Gain Controls
These two knobs and the level controls for channels
one and two respectively. Turning clockwise
will increase its gain and counter clockwise will
decrease its gain. Please always power-up with
the volume all the way down, and increase the
volume slowly to make sure that no conditions
exist which could annoy your audience or harm
your speakers.
7. CH1/CH2 Inputs (XLR Connectors)
These inputs are provided for making balanced
connection to mixers, preamps, etc. The XLR
inputs are wired as per the following convention:
8. Balanced Barrier Strip Inputs
These connection points provide the best option for
permanent or long-term installation. Connections
should be screwed down tight to exclude oxygen,
and care should be taken to avoid loose strands of
wire that may cause short circuits.
9. CH1/CH2 Parallel Pass Through XLR
Connectors
These XLR output connectors are provided
for parallel connection to another Icon or other
amplifier.
10. Stereo/Parallel/Bridge Switch
In Stereo operation, two separate signals are
treated separately by channels 1 and 2 of the
amplifiers.
In Parallel operation, one signal is treated by
bother channel 1 and 2 of the amplifier. In other
words, a signal connected to Input CH1 (6) or CH2
(7) is sent to both Output CH1 (10) and CH2 (11).
In Bridge operation, both channels are configured
to drive a single load with a single signal to CH1
(only CH1 is operative, and CH2 input must be
vacant) at twice the power.
This switch should only be used when the
Amplifier is off; otherwise the speakers'
components could be damaged.
11. Direct Output Connectors, CH1/CH2
These are barrier strips to connect low impedance
speakers. Spade lugs and bare wires should both
be screwed down tight to exclude oxygen, and care
should be taken to avoid loose strands of wire that
may cause short circuits.
12. Audio Transformer Outputs, CH1/CH2
These are barrier strips to connect distributed line
(25V, 70V, 100V, 140V and 200V). Spade lugs
and bare wires should both be screwed down tight
to exclude oxygen, and care should be taken to
avoid loose strands of wire that may cause short
circuits.
