IR Wideband Modulator with Integral Radiator
The SI 30 is a wideband modulator with an integral radiator. It can be switched between
operation on channel 1 (2.3 MHz), channel 2 (2.8 MHz) and stereo operation. Due to its
compact size and relatively low radiating power, the SI 30 modulator/radiator and the SZI
30 radiator are an ideal choice for smaller or medium-sized rooms, for covering recesses
or for applications which require transmission of audio information to well defined zones,
e.g. in museums.
NOTE: Power supply is not included. Please order as required.
Features—Benefits
• New, higher subcarrier frequencies to avoid interference with fluorescent lighting
• Easy to install
• Master system can be used independently for up to 750 sq. ft. of coverage
• SZI 30 slave emitters offer increased coverage
• Connects to line level audio source via 1/8" or 1/4" plug unbalanced
• 1-year warranty
