Designed & manufactured by New Jersey based Technology Company, Zaxcom are proud to introduce the TRX900 wireless microphone transceiver, a major advancement in the art of professional wireless.

TRX900

The TRX900 system is a remarkable product line. It simply it re-writes everything we have become used to in radio mic technology. Gone is any sense of compression, no noise reduction, com-panders or preemphasis/de-emphasis - and instead we have a totally open and natural sound with a dynamic range of 106dB - it is unlike anything else I have ever worked with before - put simply you can no longer hear the radio microphone at work, its as transparent as a quality cabled microphone. The TRX900 uses conventional frequency range between 518 - 870 MHz but due to its use of 100% digital modulation is very considerably less prone to intermodulation. 30 plus channels can be fitted into a single 30Mhz wide frequency range, meaning a theoretical 200 plus units can be used simultaneously in the UK. The Digital modulation also means clashes & drop outs are minimized - but even if a drop out does occur the digital receiver patches the sound so the effect is often impossible to detect.

The TRX900 uses the industry standard Lemo 3 pin connector, and is available powered by either two AA or one CR123 cells, giving up to five and a half hours battery life. But that's only the start of it. Arguably the world's best sounding radio mic can be remotely controlled using the IFB900 - IFB Remote Controller. This hand held battery powered device communicates with as many TRX900 transmitters as required and allows remote control of settings such as body pack audio gain, RF channel and high-pass filter - even while the transmitter is in use passing audio. It's an absolutely invaluable tool allowing the sound designer to fine tune transmitter settings and gain thresholds without interfering with the actors performance. Because the IFB900 works with RF data, as opposed to Infra Red data it is immune from interference from low frequency lighting and the actors receiver can be hidden under costume. IFB900 control has an effective range of 100m.

Equally unique to the industry is the matching RX4900 rack-mount receiver unit. 4 individual receivers are packed into a single 1U high enclosure with each channel sporting a full function LED display. Uniquely each receiver channel is actually compatible with stereo transmission Zaxcom products, and so sports 8 XLR3 outputs.

RX4900 receivers can be linked together to allow up to 16ch to operate from one set of aerials with out the need for external antenna distribution and have built in headphone monitoring across all channels with no additional hardware.

The Zaxcom system comes fully proven with complete systems used by the following West End and Touring shows:

"Sunday In The Park With George" - Wyndham's Theatre, Charing Cross Road
"Cabaret" - Lyric Theatre, Shaftesbury Avenue
"Little Shop of Horrors" - Duke of York's Theatre
"The Producers" - first ever UK national tour

TRX900 - Wireless Digital Transmitter with the capability to receive remote control commands

The Zaxcom TRX900 is intermodulation proof; up to 30 transmitters in the same frequency block can be used together at the same time Digital modulation wireless transmitter Superb audio quality that rivals a hard wire Dynamic range of 106 dB and uses 100% digital modulation - no noise reducers, companders or pre-emphasis/de-emphasis Digital drop-out protection Built-in IFB receiver (requires TRX910 earpiece adaptor) With the optional IFB transmitter remote control, settings such as body pack audio gain can be modified RF channel and high-pass filter are adjustable - even while the transmitter is in use Fixed 2 ms transmission delay 5 hour running time on a single battery Graphic LCD display Integrated Time Code transmission Small and lightweight measuring 58mm × 17mm × 53mm

IFB900 - IFB Remote Controller

The IFB900 is a handheld remote control used to remote control the TRX900. Features controlled include audio gain, transmitter frequency, high pass filter, and record/playback functions (TRX901) The data channel of the IFB900 can be used either stand-alone or with a PC laptop to remotely control a group of TRX900 body packs. As a standalone unit, the keypad and LCD display allows for remote control of all functions of a group of TRX900 body packs. When connected to a PC, the IFB900 functions as the RF interface to a remote control program that runs on the PC The maximum transmission range is 100m Internal Battery: 2 AA Batteries External: 12V DC Power output: 50mW Weight: 3oz
