Two-Channel Mode
Both pairs of channels are bridged.
Apply an input signal to the inputs of Channels 1and 3.
Connect a loudspeaker to the output of Channels 1 and 3 with a
SpeakON
NL4FC connector wired for bridge connection.*
Set the MODE switches for Channels 1 & 2 and Channels 3 & 4 to BRIDGE.
Adjust the input signal level with the LEVEL attenuators for Channels 1 and 3.
Set the CROSSOVER switches of Channels 1 and 3 to the position required for
each pair of channels (the crossover switches of Channels 2 and 4 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 Channels 1 and 3 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.
* The loudspeaker rated impedance should be at least 8Ohm.
Never attempt to jumper or otherwise link up any pins of SpeakON output connectors.
