SI 30/SZI 30

Features

Compact radiator and modulator/radiator for the carrier

frequencies 2.3 MHz and 2.8 MHz

Easy installation and precise alignment

Delivery includes:

SI 30: 1 x SI 30 modulator/radiator, 1 x AF connection cable, 3.5 mm stereo jack

plug to Texas connector, length 2 m, 1 x 3.5 mm/1/4“ stereo jack adaptor

The NT 20-1 plug-in mains unit is not included in the delivery. Please order

it separately in the version you require (European, UK or USA versions available).

General Description

The SI 30 is a wideband modulator with an integral radiator. It can be switched

be tween 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.
