Hookup Schemes for Subsequent Speakers
Using Loop-Through Terminals -- By connecting the wire pair
of a subsequent speakers to the “Loop Thru” on the Control
40 Series Loudspeakers all subsequent speakers will be
disconnected when this speaker’s connector is disconnected
during troubleshooting. This can be useful as a way to isolate
problems to a section of the distributed line while leaving the
wires attached to the connector.
Hookup Schemes for Subwoofer-Satellite
Systems Using Control 40CS/T & Control 42C
Loudspeakers
The Control 40CS/T subwoofer features a built-in crossover
network designed for use with the Control 42C Ultra-Compact
Satellite loudspeakers. Two or four Control 42C satellite
loudspeakers can be used with the Control 40CS/T to create
an extremely natural sounding and powerful subwoofer-
satellite system that is perfect for applications requiring wide
bandwidth and superior sonic performance with minimal visual
impact. Using four Control 42C satellite loudspeakers with a
Control 40CS/T will oer approximately twice the area coverage
of a system using only two Control 42C satellite loudspeakers.
The Control 40CS/T and Control 42C Sub-Sat system can
be driven either via a 70V/(100V) distributed line or in low
impedance direct mode. Like the rest of the Control 40 Series,
70V/(100V) and low impedance connections are made via the
same input connector on the Control 40CS/T. The Control 42C
Satellites are then connected to satellite output connectors
located on the Control 40CS/T. With the Transformer Tap/
Bypass switch set to the bypass/8Ω low impedance mode, the
Control 40CS/T subwoofer itself presents an 8Ω load on your
amplier, and a two satellite system also creates an 8Ω load on
your amplier, whereas a four satellite system creates a 4Ω load.
Choose whichever of the following hookup patterns best
accommodates your installation. All satellite speakers must
terminate at the Control 40CS/T subwoofer.
Connecting the Control42C Satellite to the Control
40CS/T Subwoofer
Satellite Home Run to Subwoofer -- There are four satellite
output connecdtors on the Control 40CS/T. If using only two
Control 42C satellites, connect each loudspeaker to a single
output connecdtor as shown in the diagram below; one
Control 42C in “Sat 1” and the second Control 42C to “Sat 2”
ONLY. “Sat 3” and “Sat 4” connectors should not be used.
If using four Control 42C satellites, connect each loudspeaker to
a single output connector as shown in the diagram below, one
Control 42C to “Sat 1”, the second Control 42C to “Sat 2”, the third
Control 42C to “Sat 3”, the fourth Control 42C to “Sat 4.”
Use only either two or four satellite loudspeakers as described
in the recommended congurations. Do not use one or three
satellite speakers, or it could result in uneven sound levels and /
or damage to your sound system.
