SI 20-R/SZI 30R Two Channel IR Modulator & Remote Emitter
The SI 20-R two-channel, 95/250 kHz, wideband infrared modulator is a single rack-space unit
that can drive up to eight SZI-30R emitter panels for up to 6,000 sq. ft. of coverage. This easy-to-
use, integrated system offers a cost-effective solution for ADA compliance for the hard of
hearing, simultaneous language interpretation, and other assistive listening applications. Each
SZI30-R slave emitter panel floods an area of up to 750 sq. ft. (in mono mode), and can be
remotely powered by the SI20-R. Several SZI-30R emitters can be clustered together at a single
mounting point and aimed individually, using optional clamping accessories.
