PRODUCT SPECIFICATION 8/8 evolution wireless G4 ew 300 G4-HEADMIC1-RC | Bodypack Headmic Set The receiver shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity shall be < 2 μV for 52 dBA eff S/N with HDX engaged at peak deviation. Adjacent channel rejection shall be ≥ 75 dB (typical). Intermodulation attenuation shall be ≥ 70 dB (typical); blocking shall be ≥ 75 dB. Four selectable equalizer presets shall be provided: "Flat", "Low Cut" (−3 dB at 180 Hz), "Low Cut/High Boost" (−3 dB at 180 Hz/+5.5 dB at 10 kHz) and "High Boost" (+5.5 dB at 10 kHz). Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 115 dBA. Total harmonic distortion (THD) shall be ≤ 0.9 %. The audio output level shall be adjustable within a 48 dB range in steps of 3 dB. The receiver shall operate on 12 V power supplied from the NT 2-3 CW mains unit (for 100 - 240 V AC, 50/60 Hz). Power consumption shall be 350 mA. The receiver shall have a rugged metal housing; dimensions shall be approximately 202 x 212 x 43 mm (7.95" x 8.35" x 1.69"). Weight shall be approximately 980 grams (2.16 lbs). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The receiver shall be the Sennheiser EM 300-500 G4. The transmitter shall be menu-driven with a backlit LC display showing the current frequency, frequency bank and channel number, metering of AF level, transmission status, lock status, pilot tone transmission, muting function, and battery status. An auto-lock feature shall be provided to prevent settings from being accidentally altered. The transmitter parameters shall either be configurable in the associated receiver's menu and synchronized with the transmitter via an integrated infrared interface or shall be programmable in the transmitter menu. The transmitter shall be equipped with a mute switch, which shall be switchable between "AF on/off", "RF on/off" and "Disabled" via the receiver's user interface. A 2.5 mm jack socket shall be provided for connecting a Sennheiser RMS 1 external mute switch. The settings for the external mute switch shall be switchable between "AF on/off", "RF on/off", "Push to mute" and "Push to talk" via the user interface. Nominal/peak deviation shall be ±24 kHz/±48 kHz. Frequency stability shall be ≤ ±15 ppm. RF output power at 50 Ω shall be switchable between 10 mW (typical, low) and 30 mW (typical, standard) and 50 mW (typical, high). The transmitter shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Audio frequency response shall range from 80 - 18,000 Hz (microphone) or 25 - 18,000 Hz (line). Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 115 dBA. Total harmonic distortion (THD) shall be ≤ 0.9 %. Input sensitivity shall be adjustable within a 60 dB range in steps of 3 dB. Power shall be supplied to the transmitter by two 1.5V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack. Nominal voltage shall be 2.4 V, current consumption shall be typical 180 mA at nominal voltage; ≤ 25 μA when transmitter is switched off. Operating time shall be typical 8 hours. The transmitter shall have a rugged metal housing; dimensions shall be approximately 82 x 64 x 24 mm (3.23" x 2.52" x 0.94"). Weight including the batteries shall be approximately 160 grams (5.64 oz). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The transmitter shall be the Sennheiser SK 300 G4-RC. The headset microphone shall be designed for professional „hands free" applications. Its high-quality microphone capsule shall be a pre-polarized condenser with an omni-directional pick-up pattern and shall be optimized for speech intelligibility. The headset microphone shall have an adjustable, visually unobtrusive neckband and an extremely thin microphone boom that shall be adjustable in length. The headset microphone shall be available in black (BK variant), beige (BE variant) or silver (SB variant). The frequency response of the headset microphone shall be 20 Hz-20,000 Hz (± 3 dB) and sensitivity shall be 5 mV/Pa (± 3 dB). Nominal impedance at 1 kHz shall be 1 kΩ, with a min. terminating impedance of 4.7 kΩ. Maximum SPL shall be 143 dB, equivalent noise level shall be 27 dB(A). The current consumption shall be approximately 240 μA. Operating voltage shall range from 4.5-15 V. Diameter of the microphone capsule shall be 3.3 mm (0.13"), diameter of the boom arm shall be 1.1 mm (0.04"). The cable shall be 1.6 m long and shall provide connection via a 3.5 mm jack plug or a lockable 3-pin special connector. Weight without cable shall be approximately 7 grams (0.25 oz). Operating temperature shall range from -10 °C to +50 °C (+14 °F to +122 °F). The headset microphone shall be the Sennheiser SL Headmic 1. Sennheiser electronic GmbH & Co.
