PRODUCT SPECIFICATION 7/7 evolution wireless G4 ew 112 P G4 | Camera Lavalier ME 2 Set ew 122 P G4 | Camera Lavalier ME 4 Set ARCHITECT'S SPECIFICATION A wireless RF transmission system consisting of a camera receiver and a bodypack transmitter with a clip-on microphone. The system shall operate within eleven 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; transmission frequencies shall be 1,680 per range and shall be tunable in 25 kHz steps. The system shall feature 20 fixed frequency banks with up to 12 compatible frequency presets and 1 user bank with up to 12 user programmable frequencies. The receiver shall be menu-driven with a backlit LC 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 shall be provided to prevent settings from being accidentally altered. The receiver parameters shall be programmable in the receiver menu. The receiver shall feature a 3.5 mm audio output with a maximum output of +11 dBu (mono, unbalanced). Nominal/peak deviation shall be ±24 kHz/±48 kHz. Squelch threshold shall be adjustable to three levels: Low (5 dBμV), Middle (15 dBμV) and High (25 dBμV). The receiver shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity shall be < 1.6 μV (typical) for 52 dBA eff S/N with HDX engaged at peak deviation. Adjacent channel rejection shall be ≥ 65 dB (typical). Intermodulation attenuation shall be ≥ 65 dB (typical); blocking shall be ≥ 70 dB. Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 110 dBA. Total harmonic distortion (THD) shall be ≤ 0.9 %. The audio output level shall be adjustable within a 42 dB range in steps of 6 dB. Power shall be supplied to the receiver by two 1.5 V 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 receiver is switched off. Operating time shall be typical 8 hours. The receiver 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 beapproximately 160 grams (0.35 lbs). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The receiver shall be the Sennheiser EK 100 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 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 30 mW (typical). 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 ≥ 110 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 1.5 V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack. Nominal voltage shall be 2.4 V for a rechargeable battery or 3 V for a battery, 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 (0.35 lbs). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The transmitter shall be the Sennheiser SK 100 G4. Sennheiser electronic GmbH & Co. KG · Am Labor 1 · 30900 Wedemark · Germany · www.sennheiser.com
