About Sennheiser EM 100 G4

True diversity half-rack receiver in a full-metal housing with intuitive LCD display for full control with evolution wireless G4 100 Series systems.

Architect's Specification
The stationary receiver with true diversity technology is for use with a companion transmitter as part of a wireless RF transmission system.

The receiver operates within twelve UHF frequency ranges, with a switching bandwidth of up to 42 MHz: 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 566 - 608 MHz, 606 - 648 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 806 - 810 MHz, 925 - 937.5 MHz, 1785 - 1800 MHz; receiving frequencies are 1,680 per range and are tunable in 25 kHz steps. The receiver features 20 fixed frequency banks with up to 12 compatible frequency presets and 1 user bank with up to 12 user programmable frequencies.

The receiver is menu-driven with a backlit LCD display showing the current frequency, frequency bank and channel number, metering of RF level, metering of AF level, lock status, pilot tone evaluation, muting function, and battery status of the associated transmitter. An auto-lock feature is provided to prevent settings from being accidentally altered. The receiver features an integrated guitar tuner and provides a sound check mode.

Some receiver parameters such as receiving frequency, receiver name and pilot tone setting are synchronizable with the associated transmitter via an integrated infrared interface.

The receiver features a balanced XLR-3M audio output with a maximum output of +18 dBu along with an unbalanced 1/4" (6.3 mm) audio output with a maximum output of +12 dBu. The receiver has two DATA ports (RJ 10) to set up a multichannel system. Two BNC-type input sockets are provided for connecting the antennas.

Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. Squelch threshold is adjustable to three levels: Low (5 dBmicroV), Middle (15 dBmicroV) and High (25 dBmicroV).

The receiver incorporates the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity is < 2 microV for 52 dBA eff S/N with HDX engaged at peak deviation. Adjacent channel rejection is >= 65 dB (typical). Intermodulation attenuation is >= 65 dB (typical); blocking is >= 70 dB. Four selectable equalizer presets are provided: "Flat", "Low Cut" (-3 dB at 180 Hz), "Low Cut/High Boost" (-3 dB at 180 Hz/+6 dB at 10 kHz) and "High Boost" (+6 dB at 10 kHz).

Signal-to-noise ratio at 1 mV and peak deviation is >= 110 dBA. Total harmonic distortion (THD) is <= 0.9 %. The audio output level is adjustable within a 48 dB range in steps of 3 dB.

The receiver operates on 12 V power supplied from the NT 2-3 CW mains unit (for 100 - 240 V AC, 50/60 Hz). Power consumption is 300 mA. The receiver has a rugged metal housing; dimensions are approximately 190 x 212 x 43 mm (7.48" 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 receiver is the Sennheiser EM 100 G4.
