2.6.3 Parallel-Mono Mode
Parallel-Mono mode is used to drive loads with
a total impedance of less than 4 ohms.
Typical input and output wiring is shown in
Figure 2.10.
Turn off the amplifier and set the
Stereo/Mono Switch to Parallel-Mono.
Note: It is normal for the Channel 2 IOC
indicator to stay on in Parallel-Mono mode.
INPUTS: Use only the Channel 1 input
connector.
NOTE: Crown provides a reference of wiring pin
assignments for commonly used connector
types in the Crown Amplifier Application Guide
available at www.crownaudio.
OUTPUTS:
• Connect speaker positive (+) lead to
Channel 1 red (+) binding post.
• Connect speaker negative (–) lead to
Channel 2 black (–) binding post.
• Add a 14 gauge or larger jumper between the
Channel 1 and 2 red (+) binding posts.
NOTE: The Channel 2 level control MUST
be turned down (full CCW) when operat-
ing the amplifier in Parallel-Mono mode.
CAUTION: When Parallel-Mono wiring is
installed, do not attempt to operate in
Stereo or Bridge-Mono mode until the
wiring is removed (especially the jumper
wire). Failure to do so will lresult in high
distortion and excessive heating.
