Intended for monitoring stereo audio signals in professional applications such as stage or broadcasting, this range consists of a static transmitter and mobile diversity receiver, both built in metal enclosures.
The system has a frequency-bank system with up to 16 compatible pre-set frequencies. The bandwidth is 42MHz, offering 1680 tunable UHF frequencies. An HDX compander is used to increase dynamic range, pilot-tone squelch avoids RF interference when the transmitter is turned off. Easy set-up uses the receiver to perform an automatic frequency scan to search for available frequencies. Settings may be transferred between the receiver and transmitter in either direction using infra-red communication. The transmitter may be connected to an Ethernet network for configuration of multi-channel systems using software.
Transmitter and receiver are available separately or together as a complete system. Different models are available, in several UHF ranges; each offers 26 frequency banks with up to 16 channels. Each of the channels in the first 20 frequency banks are pre-set at the factory to fixed frequencies. The channels within each bank can be used without intermodulation. The remaining banks allow the user to select and store frequencies.

This is a stereo transmitter, which can operate in mono, fed from the left audio input socket, powered by 12V DC from an included adapter. The metal case can be rack-mounted.
The front panel has a 6.35mm headphone socket, for local monitoring, with an associated volume control. A back-lit 'sync' button is used to transfer settings to a receiver. The back-lit, graphic display shows status. A standard display is presented at switch-on, showing signal levels for the two audio channels, frequency bank and channel, current transmission frequency, the name of the transmitter, transmission status and power, the current equaliser settings, the audio input sensitivity and whether the lock-mode is active. Settings are made using a jog wheel in conjunction with a menu, including a 5-band-equaliser to tailor the audio signal. An auto-lock function avoids accidental changing of settings. The transmitter can be connected to an Ethernet network, for control by a computer using the Wireless Systems Manager software, which may be downloaded; this delivers an overview of monitoring and data management for multi-channel systems.
On the rear, a coaxial socket is provided for power, an RJ45 connector connects to a network. Two combination jack and XLR connectors provide balanced, line-level audio inputs; two 3-pole jack sockets provide loop-out connections to connect to other equipment. The antenna output is a BNC connector.
Audio input: + 22 dBu maximum. Frequency response: 25Hz - 15kHz (headphones). Distortion: Less than 0.9% THD. Noise: Better than 90dBA. Modulation: FM, MPX-stereo. RF frequency range: 516 - 865 MHz. RF output power:10/30 mW switchable. Peak deviation: +/- 48 kHz: Compliance: ETS 300422, ETS 300454, 15 mW; ETS 301 489-1 / -2; FCC Part 74.861 / CANADA RSS-123, 100 mW. Power source: 12V DC, 350mA maximum. Dimensions: 212 x 202 x 43mm. Weight: 980g.
Included accessories: GA 3 rack-mounting adapter, to mount one or two receivers in a 1U 19 inch rack, NT 2 power supply unit, 12V DC output, 100-240V, 60/60 Hz input, with country-specific adapter, antenna, operating instructions.

This bodypack receiver has adaptive diversity for reliable reception; the headphone cable is utilised as a second antenna. The upper surface has a volume control, a locking, 3.5mm, stereo jack socket, for the earpiece and a whip antenna.
The front has a backlit graphic display, offering 'intuitive menu navigation' and a 'user-friendly menu' in conjunction with an up/down rocker button and set button. A standard display is presented at switch-on, showing RF signal levels, squelch threshold, transmitter modulation levels for the two audio channels, current transmission frequency, the name of the receiver, lock-mode status, battery status, mute status and whether the pilot tone is activated. Two alternative standard displays may be chosen, showing the limiter status, channel number, equaliser settings and stereo/focus mode, and other information in different combinations. Control functions include a 'Hi Boost', a multi-level limiter, stereo/focus mode and balance. An 'auto-lock function' avoids accidental changing of settings. LEDs indicate battery status and RF signal indication. The front folds down to reveal the battery compartment for 2x AA cells or a BA 2015 accupak rechargeable battery pack and the 'set' and 'escape' buttons. On the rear there is a removeable metal belt-clip.
Sensitivity: Less than 2.5uV at 52dBAeff S/N. Adjacent channel rejection: 65dB. Intermodulation: -70dB. Noise: -90dB, 1mV, at peak deviation. Output: 2 x 100mW, at 32 ohms load. Connector: 3.5 mm. Power source: 2x AA cells, operating time 4-6 hours. Dimensions: 82 x 64 x 24mm. Weight: 160g.
Included accessories: 1x IE 4 earphones, 2x AA cells, user manual.
