Three-Channel Mode (Option 2)
Using the bridge mode for one pair of channels and the individual mode for the
other.*
Apply an input signal to the inputs of Channel 1 and 3.
Connect loudspeakers to the output of Channel 1 with a
SpeakON NL4FC
connector wired for bridge connection and to the outputs of Channel 3 and 4 with
SpeakON NL2FC or NL4FC connectors wired individual-channel mode. **
Set the MODE switches for Channels 1 & 2 to BRIDGE while for Channels 3 & 4 to
MONO.
Adjust the input signal level with the LEVEL attenuators for Channels 1, 3 and 4.
Set the CROSSOVER switches of Channel 1, 3 and 4 to the required position (the
crossover switch of Channel 2 may be in any position).
Generally, it is recommended to set the input HI PASS FILTER switches to 45 Hz
(in this case only switches for Channel 1, 3 and 4 are involved). However, when it is
necessary to obtain a linear frequency response to drive full-range systems used in
studios or cinema theatres, set them to OFF. See:
Input Filter .
Note.
* Any pair of channels (1 & 2 or 3 & 4) can be operated in the bridge mode or individual mode if
properly connected and set up.
** The loudspeaker rated impedance should be at least 4Ohm for individual connection and 8Ohm
for bridge connection.
