INSTALLATION INSTRUCTIONS
CB2Z
TWO ZONE CONNECTING BLOCK
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 INPUT (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

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 +1 2 V D C power, 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.

N O T E : For clarity, connections to the 3- conductor cables in this illustration are shown in "daisy chain" fashion. It is recommended that 3- conductor "home-runs" be pulled from each room to the CB2Z Connecting Block in the main room. This maintains higher power supply voltage
