The MT–BB Accessory Panel is de-
signed to give your Micro-Tech ® ,
Power Base or CSL ™ amplifier barrier
block type inputs for permanent
installatons. Installing it requires the
access of the top side of the Main Cir-
cuit Board and should only be at-
tempted by a qualified technician.
The barrier block connector is wired
as follows:
– Negative Input
(inverting)
Signal Ground
+ Positive Input (non-
inverting)
Both balanced and unbalanced input
wiring are shown in Figures 1.2 and
1.3 opposite. Please note the jumper
between pins 1 and 3 when connect-
ing an unbalanced line to the input.
