Sennheiser SI 1015 Product Sheet

SI 1015
IR Audio Transmission Technology |
General Description
The SI 1015 wideband modulator uses the extremely reliable carrier frequencies 2.3
and 2.8 MHz and can be operated in single-channel, two-channel and stereo modes.
The modulator is fitted with two balanced XLR-3 audio inputs and IR monitoring
diodes. It can be used with SZI 1015 and SZI 1029 radiators, the signals for the
ra diators are available at two RF sockets, or, alternatively, at a barrier strip. (N.B.:
The barrier strip – which also powers the connected radiators – can only be used
with SZI 1015 and SZI 1029-24 radiators.)
Features
Modulator for the carrier frequencies 2.3 and 2.8 MHz
Single-channel, two-channel or stereo operation, features
monitoring diodes and a separate barrier strip with RF and DC outputs for
connecting radiators
