Sennheiser SI 30-2250 User Manual
General Description
Sennheiser offers system packages that include all components necessary to configure a complete system. Sennheiser’s Medium-Area Infrared Systems provide
coverage of 1500 sq. ft. to 3000 sq. ft. in single channel mode. The SI 30 transmitter and SZI 30 emitter are the primary components of the system. These are
powered by the NT20-4-120 AC power adapter and KKY20-015 octopus power
cable, which connects up to four SI30 and SZI30. For easy installation, the SI30
and SZI30 may be wall or ceiling mounted with the IZK20 mounting clamp and
IZM20 mounting hardware, in combination with the WM1 wall/ceiling mount. The
RI250 stethophone single-channel infrared receiver includes the BA151 rechargeable battery, which conveniently recharges with the L151-10/NT charging unit
with power supply.
