Outputs

Covered barrier strips located on the rear panel allow safe, shockproof  speaker cable connec-

tions to the amplifier outputs. See the diagrams for details on connecting speakers and/or

distributed (25V, 70V, 100, 140V, and 200V) lines. Insulated connectors of  the type shown are

recommended. Always make sure the amplifier is turned off  before you change any output

connections or before lifting the safety shroud.

For driving 140V or 200V distributed lines, the amplifier must be set into bridged mono

mode. See “Bridged Mono Mode” section later in this manual for information about this

mode.

Lift safety shroud.

Loosen screw terminals.
Insert wire connectors
under screws.
Tighten screw terminals.

Lower safety shroud.
