2.4.3 Parallel-Mono Hookup
Parallel-Mono Mode is intended for driving loads with a total impedance of less
than 4 ohms (see Section 2.4.2 if the load is 4 ohms or greater). Installing the
amplifier in Parallel-Mono Mode is very different from the other modes and
requires special attention.
To activate Parallel-Mono Mode:
1. Turn off the amplifier
2. Wait at least 10 seconds
3. Slide the Dual/Mono switch to the left (as you face the back panel).
4. Connect the input signal to Channel 1, and do not use the Channel 2 input
Both outputs will now receive the signal from the Channel 1 input.
NOTE: The Channel 2 input and level controls are disconnected in Parallel-
Mono Mode. A signal-feeding Channel 2 will have no effect on the output.
To complete connections:
5. Install a jumper wire between the positive (+) outputs of Channel 1 and 2 that
is at least 14 gauge in size.
6. Connect the load to the output of Channel 1 as shown below.
7. Connect positive (+) lead from the load to the positive (+) Channel 1 terminal
8. Connect the negative (-) lead from the load to the negative (-) Channel 1
terminal.
NOTE: Remember to remove the jumper between the positive output
terminals before changing to Bridge-Mono or Dual Modes (improper
operation will result if you don't).
