MTC-CBT-70T is a bolt-ontransformer module to adaptCBT 70J-1 and CBT 70JE-1 (andCBT 70J-1/JE-1 arrays) for use ondistributed loudspeaker lines. It allows long cable runs and multiple speakers to be driven from a single distributed system amplifier channel.

Transformer taps include 120W,60W, and 30W for 70V and 100Vdistributed lines, plus 15W for 70Vonly.

Connections are made via customer-supplied cable to screw down terminals inside the enclosure.
Two gland nuts are provided – one for the cable into the enclosure from the amplifier and one for the cable from the enclosed terminal strip to the input terminal of the loudspeaker.

The tap selection is made via theterminal connection of the cable fromthe power amplifier to the appropriate terminals on the internalterminal strip.
