Using PM8500/N MONO Mode (single channel) to Drive Hi-Z Loudspeaker Loads

Using PM8500/N MONO Mode (single channel) to Drive Hi-Z Loudspeaker Loads
On the PowerMatch PM8500 amplifier, Constant-Voltage (or “Hi-Z”) operation is typically accomplished by using
V-Bridge (2 channels paired) or Quad modes (4 channels paired). Within these modes the appropriate configuration
for 70V or 100V operation can be selected. Some users have expressed a desire to have more channels available for
Hi-Z operation, to drive 70V or 100V speakers with only one amplifier channel. This document describes the considerations when connecting Hi-Z loads to individual channels (Mono Mode)
