To wire Control 40 Series loudspeakers simply connect the positive wire to the “+” pin and connect the negative wire to the “-” pin. The “IN” pins are paralled to the “LOOP THRU” pins (+ and - respectively) inside the loudspeaker. The “Loop Thru” pins allow a parallel connection to an additional loudspeaker.

To select the operating mode or desired output tap of the loudspeaker, simply rotate the tap selector switch located on the front of the baffle to the desired setting.

Note: Both 70V/(100V) connections and low impedance connections are made via the same input pins. When using the transformer tap selections, be sure that the power amplifier is set on 70V/(100V) mode and the leads feeding the system are connected to 70V/(100V) outputs on the amplifier.
