Sennheiser EK 500 G4 Wireless Pro Camera Receiver, GW1: 558 - 608 MHz

Powerful black camera receiver with increased bandwidth and transmission power for evolution wireless G4 500P Series systems. For professional film productions, easily mounted on any kind of camera.

Architect's Specification
The compact camera receiver with adaptive diversity technology is for use with a companion transmitter as part of a wireless RF monitoring system.

The receiver operates within ten UHF frequency ranges, with a switching bandwidth of up to 88 MHz: 470 - 558 MHz, 520 - 558 MHz, 558 - 608 MHz, 558 - 626 MHz, 606 - 678 MHz, 626 - 698 MHz, 718 - 790 MHz, 790 - 865 MHz, 806 - 810 MHz, 925 - 937.5 MHz; transmission frequencies is 2,880 per range and is tunable in 25 kHz steps. The receiver features 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 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, battery status, muting function or line output level, and pilot tone evaluation. An auto-lock feature is provided to prevent settings from being accidentally altered.

The receiver parameters is either configurable in the associated transmitter's menu and synchronized with the receiver via an integrated infrared interface or is programmable in the receiver menu.

The receiver features a 3.5 mm audio output with a maximum output of +17 dBu (mono, unbalanced) and a 3.5 mm phone output.

Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. Squelch threshold is defeatable (off) or 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 < 1.6 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. Signal-to-noise ratio at 1 mV and peak deviation is >= 110 dBA (line) or approximately 90 dbA (phones). Total harmonic distortion (THD) is <= 0.9 %. The audio output level is adjustable within a 42 dB range in steps of 6 dB.

Power is supplied to the receiver by two 1.5V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack. Nominal voltage is 2.4 V, current consumption is typical 140 mA at nominal voltage; <= 25 microA when receiver is switched off. Operating time is typical 8 hours. The receiver has a rugged metal housing; dimensions are approximately 82 x 64 x 24 mm (3.23" x 2.52" x 0.94"). Weight including the batteries is approximately 130 grams (0.29 lbs). Operating temperature ranges from -10 Degree C to +55 Degree C (+14 Degree F to +131 Degree F).

The receiver is the Sennheiser EK 500 G4.
