Wideband Distribution Systems
Wideband distribution systems can offer high quality audio for music or speech distribution over a large area for uses such as hearing support systems or audio commentary in auditoria. A variety of radiators and receivers are available depending on the application. Full manufacturers details and technical specifications available on request.
Dual channel wideband modulator (transmitter) which replaces the earlier SI 1013 unit. Using the new interference-free 2.3/2.8MHz modulation frequencies, this modulator is switchable Ch.1 only/Ch.2 only/dual mono/stereo. Inputs are via XLRs, outputs on BNCs and barrier strips. Powered by NT 1015 mains power supply (not included, please order 54-735), which can also power up to two SZI 1015 radiators or one SZI 1029-24 radiator.
Mains powered radiator with 144 Infra-red transmitting diodes. Suitable for both wideband and narrowband operation. BNC input connector for connection to modulator plus an additional BNC output connector for looping to additional radiators. 3/8 inch thread for easy mounting. Suitable for coverage of large areas such as auditoria. 5W radiating power. Dimensions: 250 x 180 x 80mm, weight: 2.1kg.
Medium power, 2 watt infrared radiator with half the power of the SZI 1029 unit. Two units can be DC powered via the SI 1015 modulator or directly with NT 1015 power supply. SZl 1015-T variant is also available and has built-in 2W modulator (2.3MHz only).
Small to medium power, wideband modulator, with integral 0.5 watt infrared radiator. An ideal choice for smaller to medium sized rooms, or recesses on larger applications. Switchable between single 2.3/2.8 MHz channels or two channel stereo operation. Can be linked with up to 4 SZI additional radiators. 24V DC powered - supplied without power supply, but NT20-4-UK is available for UK use. To power clusters of up to 4 SI 30/SZI 30 units, an additional KKY 20-015 4-way cable is also required. SI 30 is supplied with SZI 30 radiator/slave unit and interconnection audio cable. Carrier frequency: 2.3/2.8Mhz, Audio frequency response: 50-18000Hz, distortion: < 1%, weight: 140g.
Small to medium power, wideband radiator, capable of handling up to 0.5 watt power. Suits operation with SI 30 modulator. Can be linked with up to 3 other SZI additional radiators to an SI 30. DC powered - supplied without power supply, but NT20-4-UK is available for UK use (see SI 30 for details). Audio frequency response: depends on modulator, Audio signal to noise ratio: > 60dB(A), distortion: < 1%, weight: 135g.
