Sennheiser SI 29-5/NT Five Channel Narrowband IR Modulator

Each of these 1U / 1RU rack unit modulators can handle up to five narrowband channels and has the capability of being daisy-chained with additional SI 29-5 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 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 includes an NT 29 power supply.

Features:

• Modulator with up to five narrow-band audio channels
• Each audio channel can be programmed to any of the 32 carrier frequencies
• Several units can be cascaded to make systems of up to 32 channels
