Infrared Conference Equipment Multi-Channel IR Modulator

Sennheiser Pro Audio Products

Pro Audio Products

Description

Each of these one-rack-space-high modulators can handle up to five narrowband channels and has the capability of being daisy-chained with additional Sennheiser SI-29-5-NT to configure systems of up to 32 channels. Using Phase Locked Loop frequency synthesis, the five channels can be programmed to transmit on any of the 32 available frequencies. If SI295/NT systems of less than five channels are required, non-active channels can be turned off, resulting in increased transmission range from SZI 1029 or SZI 1015 emitter panels. The SI 29-5 requires an NT 29-120 AC power supply.
