B&K CT300.3 Getting Started Manual

Step 1 

Unpacking the Unit

Warning: Do NOT plug the AC power cord into the unit until connections are completed 

Step 2 

Turn the Unit to the Back Panel

Connect all Sources

Connect the analog audio and composite video from all sources into IN 1 through IN 9 if the sources are to be shared 

throughout all zones in the CT Receiver (shown below). Dedicated inputs are labeled as In A, In B, etc. When connect-

ing a source that is only being used for a specific zone, connect the source into the dedicated input for that zone.          

IE. Dedicated source for Zone A would be connected to In A (not shown).

Step 7 

Connect all speakers

If using the internal amplifier channels, connect the speaker wires into the phoenix adapters for each zone. If using 

an external amplifier, connect the analog pre-outs for that zone to an external amplifier. A control output is also 

available to trigger the amplifier if necessary. Please see the manual for additional information.  

Step 5 

Connect all monitors

Connect all monitors using the composite Zone Line outputs.  

Observe polarity when connecting speakers

Step 6 

The CK 1.2 and CK 1.1 keypads connect with a straight through CAT-5 cable to the Zone Control I/O ports on the back of the CT. 

The wiring diagrams are located on the back panel of the CT Receiver for the CT connections and the side of the keypad for the 

keypad connections.  

Connecting Multiple CT Receivers

Second CT Receiver 

First CT Receiver 

Signal from Source piece 

To connect multiple CT Receivers, the Source In/Out (Buffered Signal) and Link In/Out would be used. The Buffered 

In/Out connections would carry audio and video signal between multiple CT Receivers. The Link In/Out connections 

would carry communication between the CT Receivers. All source pieces would connect to the first CT Receiver and 

then the signal would go from Buffered out on that receiver using a straight through CAT-5 cable to the Buffered In on 

the second receiver. The Link Out on the first CT Receiver would go into the Link In on the second receiver and all IR 

flashers would be connected to the first receiver. For more information please see the CT 600.3/600.1/300.3 manual. 

Incorrect wiring of 

keypad connections 

may cause damage to 

the keypad and/or CT 

Receiver.

CT 600.3, 600.1 and 300.3

Getting Started

IR routing can also be accomplished in the CT Receiver. There are 9 IR flasher outputs for source control and also an IR In, IR pass 

and All IR Out for additional IR routing through the CT Receiver. Please see the CT receiver manual for more information. 

Step 3 

When using the 

preouts Zones 

A,B and C have 

a fixed output 

and Zones D, E 

and F have a 

variable output. 

Note: The manual and other pertinent documentation can be located on the CD that comes with the CT Receivers.
