Outputs
Wiring connections are shown on the back of the chassis. Carefully note the polarity marks, which are arranged to make
Bridge Mode connections easier. Four-channel models are shown in the examples; two-channel models are similar.
WARNING!: Do not touch output terminals while amplifier power is on. Make all connections with
amplifier turned off. Risk of hazardous energy!
Low Impedance Outputs
Stereo and Parallel Mode: Connect each loudspeaker to its own channel of the amplifier, as shown on the chassis label.
The mode configuration switches must be set for Stereo or Parallel mode.
Bridge Mode: Bridge mode configures the channel pair to drive a single high-power loudspeaker load. The mode
configuration switches must be set for Bridge mode. Use only the first channel's input and Gain control. Set the second
channel's Gain control at minimum.
Distributed Outputs ("V" models, 70V/140V)
Stereo and Parallel Mode: Connect each 70V circuit to its own channel of the amplifier, as shown on the chassis label.
The mode configuration switches must be set for Stereo or Parallel mode.
WARNING!: 70V Output- Risk of hazardous energy! Use Class 2 wiring for 70V outputs.
Bridge Mode: Bridge mode configures the channel pair to drive a single 140V audio circuit. The mode configuration
switches must be set for Bridge mode. Use only the first channel's input and Gain control. Set the second channel's Gain
control at minimum. Connect the load as shown on the chassis label.
140V BRIDGE MODE PRECAUTIONS:
NOTE:
Class 3 Wiring shall be used for bridged mono 140V outputs.
NOTE: Connect only 140V distributed audio circuits in bridged mode. Do not use 70V loads in bridge
mode! Use Stereo or Parallel mode channels to drive 70V loads. 140V is the minimum for bridge mode
operation.
