Sennheiser . SI29-5/NT

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 SI29-5s 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 may 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.
