ARCHITECT’S

SPECIFICATIONS

The wideband infrared modulator with

integral radiator shall be for use with

companion radiators as part of a wireless

IR transmission system. Nominal deviation

shall be +/- 50 kHz.

The modulator shall be capable of opera-

ting on the carrier frequencies of 2.3 and

2.8 MHz and shall be switchable between

single-channel, two-channel and stereo

operation.

The modulator shall feature IR diodes and

shall provide a 3-pin Texas socket as audio

input. The input voltage range shall be

45 mV - 4 V, output impedance shall be

50 ohms.

The modulator‘s maximum coverage area

shall be 80 sq m (861.11 sq ft), with a radi-

ating power of 0.5 W. The operating voltage

shall be 24-27 V DC, current consumption

shall be 180 mA. The RF output for connec-

tion of additional radiators shall be a 3.5 mm

mono jack socket.

The modulator dimensions shall be

118 x 25 x 90 mm (46.46“ x 9.84“ x 35.43“).

Weight shall be 140 grams (4.94 oz).

The modulator shall be the Sennheiser SI 30.

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.
