Sonance CB2Z User Manual
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

NOTE: For clarity,
connections to the 3conductor cables in this
illustration are shown in
"daisy chain" fashion. It is
recommended that 3conductor "home-runs" be
pulled from each room to the
CB2Z Connecting Block in the
main room. This maintains
higher power supply voltage
INSTALLATION
Fig. 3, see below, shows a typical two-zone installation with a total of four remote rooms. A variety of Sonance IR
Receivers are shown, two in each zone. When configuring a system, please keep the following items in mind:
1. More IR Receivers may be wired in parallel, in the same manner as shown, up to a maximum of 12. More than 12
is not recommended because IR noise picked up by the many IR receivers may cause erratic operation and reduce
remote control range.
2. Be sure to connect the +12VDCpower, SIGNAL output, and G N D ground of each IR Receiver or keypad to
the respective +12VDC, SIGNAL and GND of the connecting block as shown.
