7. Because of this current sharing feature, you may plug in any combination of emitter models E1, VE1, E2, &
VE2 to the CB1 (up to a maximum of 8
individual emitters) to drive the desired number of devices.
NOTE 1: Be sure the PS1 Power Supply is plugged into an un-switched AC outlet. This maintains
the system in "standby" operation so that power-on commands can be sent to the controlled
equipment.
IMPORTANT NOTE: When using long lengths (more than 200 feet) of inter-room shielded cable, it
may be necessary to connect a 470 ohm 1/8 watt resistor between input (signal) and GND at the
IR input terminals of Sonance Connecting Blocks, Zone Controllers, etc. Refer to Fig. 3. The
resistor discharges the cable capacitance more quietly, allowing IR codes of high bit rates to
pass without data loss.
