Wiring INSTRUCTIONS, CON’T

Hookup Schemes for Subsequent Speakers

Using Loop-ThroughTerminals -- 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.

Connecting the Control42C Satellite to the Control 40CS/T Subwoofer

Satellite Home Run to Subwoofer -- There are four satellite output pins on the Control 40CS/T. If using only two Control 42C satellites, connect each loudspeaker to a single output pin 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.

To 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

From Amplifier

If using four Control 42C satellites, connect each loudspeaker to a single output connector as shown in the diagram below, one Control 42C in “Sat 1”, the second Control 42C to “Sat 2”, the third Control 42C to “Sat 3”, the fourth Control 42C to “Sat 4.”

Control 42C satellite loudspeakers with a Control 40CS/ T will offer approximately twice the area coverage than 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 pins on the Control 40CS/T.

To Control 42C

The Control 42C Satellites are then connected to satellite output connectors located on the Control 40CS/T. In low impedance mode, a two satellite system creates an 8Ω load on your amplifier 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.

From Amplifier

Use only two or four satellite loudspeakers as described in the recommended configurations. Failure to do so may result in uneven sound levels and / or damage to your sound system.
