General Description
Sennheiser offers system packages that include all components necessary to configure a complete system. Sennheiser’s Large-Area Infrared Systems provide coverage of 4,000 sq. ft. up to 12,500 sq. ft. in both single and dual channel modes.
The SI1015 modulator and SZI1015 or SZI1029 emitters are the primary components of the systems. The NT1015-120 will provide power for the SI1015 modulator and up to two SZI1015 or SZI1029 emitters. The SZA1060 terminating resistor
(50 ohm), for the last emitter in a daisy chain, is included for system designs that
incorporate daisy chaining of emitters. The GA1031-CC rack adapter allows for
easy mounting of a SI1015 modulator to a 19” rack. The WM1 wall/ceiling mount
easily mounts the SZI1015 or SZI1029 emitter panels. The RI250 stethophone
infrared receivers are for use with single channel systems operating at 2.3 MHz,
and include the BA151 rechargeable battery. Alternatively, for dual channel systems, the HDI302 stethophone infrared receiver is for use with systems operating
at 2.3/2.8 MHz, and also includes the BA151 rechargeable battery. The BA151
rechargeable batteries can be conveniently recharged with the L151-10 charging
unit(s) with the NT92-120 power supply. In addition, the NT2013-120 will power
two to five L151-10 charging units.
