LOOP OUTPUT

The amp is provided with a LOOP OUTPUT. The loop output provides at a unity gain the

same signal that is sourced to the GLOBAL INPUT. This output can be used to gang

amplifiers to obtain more zones of music or used as a source for other components.

INSTALLATION

Setup Selections

SELECTING INPUTS

Caution: Before making any changes to the Bridged or Global In switch positions insure that the Master

Power switch on the rear of the amp is OFF. Possible damage to the amp may occur due high

transient current during switching or from wiring misconfiguration.

Global In/Line In Switch

This switch allows the user to select the source for each zone from the Global In Input or a separate

source input via the Line In Input on each zone.

Bridge/Mono Switch

In certain instances the user may require addition power for some applications. 140 watts at 8 ohms

may be obtained. When in the Bridged mode you are combining two channels per Zone to

accomplish the increased power. NOTE: You will require two Zones (four channels) to get the

increased power for stereo. Pull Speaker Plug to see the Bridged wiring scheme.

Caution: make sure the Master Power switch is OFF before making changes.

Position The Bridge-Mono/Normal switch to the Bridge mode. Next remove speaker plug from the

chassis and connect the (-) speaker wire lead (normally black) to the R+ on the plug. Even though it

may appear wrong this is correct. Now connect the (+) speaker wire lead (normally red) to the L+ on

the plug. Check your work then insert the plug back into the female socket for that zone. If you

require stereo select another zone and do the same for that zone. Designate one of the combined

zones as LEFT and the other combined zone as the RIGHT channel.

Caution: DO NOT connect more than one speaker to the output in the Bridge mode. Maintain an

8 ohm minimum load when using the Bridge mode.
