Description
The JBL MTC-CBT-70T is a bolt-on transformer module that adapts the CBT 70J-1 line array column and the CBT 70JE-1 extension, alone or as an array, for 70V and 100V distributed lines. Long cable runs and several speakers can then run from one distributed-system amplifier channel.
The module bolts to two side-by-side M6 insert points on the back of the cabinet and extends 86 mm (3.4 in.) behind it. Cable from the amplifier enters through one gland nut to a barrier strip inside, where the tap is chosen, and a second cable runs from the strip to the speaker input. Both gland nuts seal watertight on round-jacketed cable of 4.0 to 9.0 mm (0.16 to 0.36 in.) outside diameter.
