Sennheiser SR IEM G4 Stereo Transmitter, GA 3 Rackmount Kit, A1: 470 - 516 MHz

Half-rack stereo transmitter in a full-metal housing with OLED display for full control delivering clarity along the whole frequency spectrum for daily use on stage with evolution wireless G4 In Ear Monitoring systems.

Architech's Specification
The wireless stereo rack-mount transmitter is for use with a companion transmitter as part of a wireless RF monitoring system.

The transmitter operates within nine UHF frequency ranges, with a switching bandwidth of up to 42 MHz: 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 566 - 608 MHz, 606 - 648 MHz; receiving frequencies are 1,680 per range and are tunable in 25 kHz steps. The transmitter features 20 fixed frequency banks with up to 16 compatible frequency presets and 6 user banks with up to 16 user programmable frequencies.

The transmitter is menu-driven with a backlit OLED display showing the current frequency, frequency bank and channel number, metering of AF level, transmission status, transmission power, equalizer setting, input sensitivity, and lock status. An auto-lock feature is provided to prevent settings from being accidentally altered.

The parameters of associated receivers are configurable in the transmitter menu and synchronized with the receivers via an integrated infrared interface.

Frequency stability is +/-10 ppm. RF output power at 50 Ohm is switchable between 10 mW (low), 30 mW (standard) and 50 mW (high).

The stereo audio input utilizes two discrete (left/right) electronically balanced 1/4" (6.3 mm) jack/XLR-3F combo sockets; the audio output utilizes a balanced 1/4" (6.3 mm) jack socket; an audio loop output is provided utilizing two balanced 1/4" (6.3 mm) jack sockets. A headphone output with headphone volume control is provided and utilizes a 1/4" (6.3 mm) stereo jack socket. The transmitter has an Ethernet port (RJ-45) for remote network-based monitoring and control using the Sennheiser Wireless System Manager software. One 50 Ohm BNC-type input socket is provided for connecting the antenna.

Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. The transmitter incorporates the Sennheiser HDX compander system and includes a 19-kHz MPX pilot tone with a +/-5 kHz deviation. The audio frequency response ranges from 25 -15,000 Hz. Maximum input level is +22 dBu. Total harmonic distortion (THD) at 1 mV and nominal deviation is < 0.9 %. Signal-to-noise ratio at nominal load and peak deviation is > 90 dB.

The transmitter operates on 12 V power supplied from the NT 2-3 mains unit (for 100 - 240 V AC, 50/60 Hz). Power consumption is 350 mA. The transmitter has a rugged metal housing; dimensions are approximately 202 x 212 x 43 mm (7.95" x 8.35" x 1.69"). Weight is approximately 980 grams (2.16 lbs). Operating temperature ranges from -10 Degree C to +55 Degree C (+14 Degree F to +131 Degree F).

The transmitter is the Sennheiser SR IEM G4.
