PRODUCT SPECIFICATION
SI 1015
Wideband Modulator
1/2
The SI 1015 wideband modulator uses the reliable carrier frequencies 2.3 and 2.8 MHz and can be operated in sing-
le-channel, two-channel and stereo modes. The modulator is fitted with two balanced XLR-3 audio inputs and IR moni-
toring diodes. It can be used with SZI 1015 and SZI 1029 radiators, the signals for the radiators 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
• Wideband modulator for the carrier frequencies 2.3 and
2.8 MHz

ARCHITECT‘S SPECIFICATION
The wideband infrared modulator shall be for use with companion radiators as part of a wireless IR assistive listening
system or IR language transmission system. The modulator shall provide coverage for up to 400 sq m (4305,56 sq ft). The
modulator shall be capable of operating on the carrier frequencies of 2.3 and 2.8 MHz and shall be switchable between
single-channel, twochannel and stereo operation. The modulator shall feature IR monitoring diodes and shall provide two
balanced XLR-3 audio inputs. Input impedance shall be 600 ohms, the input voltage range shall be 10 mV – 5 V (line). The
RF signals for the radiators shall be available at two BNC-type RF sockets or, alternatively, at a separate barrier strip with
RF and DC outputs. Nominal deviation shall be +/- 40 kHz, peak deviation shall be +/- 56 kHz. The operating voltage shall
be 24 – 30 V DC, current consumption shall be < 140 mA. The modulator shall feature a 9.5" 1U rack-mountable housing
and shall come complete with two rack-mount ears. The modulator dimensions without rackmount ears shall be 224 x 44
x 173 mm. Weight without rack-mount ears shall be 800 grams (1.8 lbs.).
The modulator shall be the Sennheiser SI 1015.
