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.

SPECIFICATIONS
• Inputs: 2 - Four screw removable
connectors to interface with all
3-wire IR receivers (see Caution
Note, Fig. 2, below)
• Outputs:Two zone emitter ports and 1
common emitter port (3.5mm
miniature phone jacks).
• Can be used with a CB1 Connecting Block or
an ACB1 Amplified Connecting Block for
COMMON emitter expansion. (See Fig. 4 & 5)
• Uses Sonance E1, VE1, E2 and VE2 Mini Emitters.
• Power requirements: 12 volts DC. Uses PS1
or PS2 Power Supplies.
• 2.1 mm coaxial power jack.
• Dimensions: 2-3/8"W x 3"D x 13/16" H.
CAUTION: 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
GROUND (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
