Control Contractor 40 Series in-ceiling loudspeakers
include Euroblock locking input connectors that allow the
system to be "pre-wired".
Connecting the Wiring to the Euroblock
-- Connect the wiring to the removable
locking connector that is INCLUDED with
the speaker by stripping the insulation
back about 5 mm (about 3/16 inch),
inserting the bare end of wire into the
connector and screwing down the hold-
down screw until tight using a small
flatblade screwdriver. Tighten any unused
screws to avoid vibration. Using terminal
block connectors allows the system to be pre-wired before
final installation of the product.
When wiring Control Contractor 40 Series loudspeakers,
always use proper electrical wiring practices in accordance
with your area's building codes and regulations.

Contractor 40 Series Loudspeakers -- The input terminal

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.
