Keypads with other B & K Receivers and Preamps
The CK1.2 Keypad can be easily programmed with the commands for all
remote controlled B & K receivers and preamps. Because of B & K’s elegant
all discrete code architecture, the CK1.2 will automate and delight owners of
any B & K receiver or preamp. You can simply connect the keypad to any B
& K receiver or preamp directly to control just the B & K (with the addition of
an inexpensive 12VDC power supply). However, the best way to connect is
to utilize an Infared Repeater system to connect your B & K keypads to both
your B & K receiver/preamp and your other brand sources and devices.
Infrared repeater systems are available from reputable manufacturers like:
Infrared Repeaters for Any Brand of Receiver/Preamp
Infrared repeater connecting blocks enable you to use the CK1.2 with any
brand of infrared remote controlled receiver or preamp. However, infrared
repeaters do not support RS232 communications, so a change in source
made via the receiver’s original remote control will not update the screen of
the CK1.2 the way it does when connected to a B & K CT610/600 or CT310.
Thus, in systems like this, the best advice is to always use the keypad to
change sources, not the remote control to keep things “in sync”. All Infrared
repeaters incorporate three conductors that connect to the CK1.2 keypad.
These connect as follows.

Repeaters are typically shipped with a power supply of about 500ma.
Should your system require more than five keypads purchase a larger 9-
12vDC unregulated power supply.
Audioplex and Xantech infrared repeater connecting blocks incorporate an
additional feature: A jack that enables a fourth conductor to send 12VDC
status when the preamp/receiver is on. This requires that your
preamp/receiver have a the switched outlet on the rear. If it does, you sim-
ply plug a 12VDC power supply in the outlet and connect to the status input
on the repeater. You then connect a fourth conductor to each CK1.2 keypad
to the Status In connector.
