CONNECTIONS: OUTPUTS

BRIDGE MODE PRECAUTIONS:

Do not use 2 ohm or 4 ohm loads in bridge mode! 8

ohms is the minimum impedance for bridge mode

operation. This mode puts a high demand on the

amplifier and speaker. Excessive clipping may cause

protective muting or speaker damage. Ensure the speaker has

a sufficient power rating.

Refer to the label on the rear panel of the amplifier for proper wiring connections. The output connection for STEREO and

PARALLEL modes is on the left side of the label , while the output connection for BRIDGE mode is shown to the right side of

the label. Note: Polarity changes from channel to channel and is different for bridge mode. Be certain of polarity of connec-

tions before applying power. Reversed polarity may degrade audio frequency response.

Speaker connection diagrams and “MODE” switch settings are printed on a rear panel label, as shown, above.

Outputs

Stereo and Parallel Mode

Bridge Mode

In bridge mode, each speaker is connected to a bridged-pair of

outputs. The channels must first be “bridged” by setting the

mode configuration switches to the bridge settings. Then con-

nect the speakers as shown on the right side of the connection

diagram (rear panel) or in the diagram, right.

Use 8 ohm minimum impedance in bridged mode.

Ensure the mode configuration switches are set for bridge

mode when connecting speakers to bridged output pairs .

In stereo or parallel mode, each speaker is connected to its

own individual channel of the amplifier. This connection

method is shown on the left side of the connection diagram

(rear panel) or in the diagram, right.

Use 4 ohm minimum impedance in stereo or parallel

mode. Ensure the mode configuration switches are set for

stereo or parallel mode when connecting speakers to each

channel’s output.

Bridge connection- single speaker shown connected to am-

plifier channels 5 and 6 (bridged with mode switch settings).

Ensure that all speaker connections maintain proper polar-

ity ( + to +, - to - ).

Stereo or parallel connection- single speaker shown con-

nected to amplifier channel 6 output. Ensure that all speaker

connections maintain proper polarity ( + to +, - to - ).
