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.

additional loudspeaker.
To select the operating mode or desired output tap of the
loudspeaker, simply rotate the tap selector switch located

feeding the system are connected to 70V/(100V) outputs
on the amplifier.
