INSTALLATION INSTRUCTIONS
The Model CB2Z is a device that provides routing of infrared remote control signals. Independent
control of two audio/video systems can be obtained from two zones. One emitter port is provided
for each zone, plus one common port so that certain components can be controlled from both zones.
The CB2Z is a simplified unit, intended for use when only two zones are needed.

C A U T I O N : For Shielded Wire and Long Lead Lengths
When using lengths greater than 200 feet of inter-room shielded cable, it may be
necessary to connect a 470 Ohm 1/8 Watt resistor between I N P U T (SIG) and
G R O U N D (GND) at the IR input terminals of the CB2Z. Refer to Fig. 2, above. The
resistor discharges the cable capacitance more quickly, allowing IR codes of high bit

- Page 3 Power Supply Requirement: 1 . Most IR receivers draw 2 milliamps (mA) without signal and 10 mA with signal (check specs. on actual model). 2 . The maximum current for proper operation from the PS1 Power Supply is 200 ma. 3 .
- Page 4 Because the Z O N E and C O M M O N jacks on the CB2Z are connected in series, you must CAUTION: have an emitter(s), a connecting block (with emitters), or other Sonance IR controlled device plugged into the COMMON jack for the zone emitters to operate! This is true for the ZONE OUTPUT jack as well.
