Architects Specifications
SI1015-8000 Dual
The infrared system shall be modular and provide coverage for up to 8,000 square feet in dual channel mode.
The SI1015 modulator must utilize the higher sub-carrier frequencies of 2.3 and 2.8 MHz for single, two channel or stereo operation with an AF fre-
quency response of 50-15,000 Hz. It must be rack-mountable and have two monitoring diodes for the technician. It must accept line level audio input
via XLR connector. It must be easy to install using barrier strip with RF and DC outputs for connecting to emitters; and, alternatively, BNC connectors for
connecting the RF signal only. It must have AF level controls with LED’s indicating peak volumes. The modulator must be capable of remotely powering
one or two emitters.
The power supply NT1015-120 shall provide power for one SI1015 emitter and up to two SZI1015, and shall have an input voltage of 100-240 V (1.3
A), an output voltage of approx. 29 V and an output current of 1.7 A.
The GA 1031-CC rack adapter is capable of mounting an individual SI 1015 modulator to a 19” rack.
The SZI1015 emitters shall be wall or ceiling mountable via a mounting clamp with 5/8” external male thread, and the mounting plate shall have a
diameter of 1 5/8”.
The stethophone shall be a two channel IR receiver with the following: wideband FM, stereo modulation, 2.3 and 2.8 MHz carrier frequencies, 18-18,000
Hz AF frequency response, greater than 1% THD, typ. 65 dB Signal-to-noise ratio, approx. 110 dB max. SPL, approx. 5 hours operating time, and a weight
of approx. 1.58 oz. (including battery pack). The stethophone shall be a Sennheiser HDI302. The receivers shall contain a rechargeable Nickel Metal
Hydride battery, which can easily be recharged with the L151-10/NT charging device (with power supply) for up to ten rechargeable batteries. The
NT2013-120 power supply is capable of powering two to five of the L151-10 charging units.
The SZI1015 shall be an infrared emitter with a carrier frequency band that extends to 6 MHz RF input (50 mV to 3V) via BNC socket or barrier strip, RF
output via BNC socket or barrier strip. The unit shall offer excellent reliability due to 72 individual diodes. The unit shall offer an operating voltage of
25-30 V DC and weigh approx. 3 lbs. The unit shall be a Sennheiser SZI1015. Coverage: 2,000 sq. ft. in two channel mode (per emitter).
The SZA1060 shall weigh 1.0 oz and be a 50 ohm terminating resistor for the last emitter in a daisy chain.
