PRODUCT SPECIFICATION 6/6 evolution wireless G4 ew 500 BOOM G4 Pro Camera Plug-on Transmitter set ARCHITECT'S SPECIFICATION A wireless RF transmission system consisting of a compact camera receiver, a bodypack transmitter with a condensor clip-on microphone and a plug-on transmitter The system shall operate 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; receiving frequencies shall be 3520 per range and shall be tunable in 25 kHz steps. The system shall feature 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 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 either be configurable in the associated transmitter's menu and synchronized with the receiver via an integrated infrared interface or shall be programmable in the receiver menu. The receiver shall feature a 3.5 mm audio output with a maximum output of +17 dBu (mono, balanced) and a 3.5 mm phone output. Nominal/peak deviation shall be ±24 kHz/±48 kHz. Squelch threshold shall be defeatable (off) or 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 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 (line) or approximately 90 dbA (phones). 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 1.5V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack. Nominal voltage shall be 2.4 V, current consumption shall be typical 140 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 be approximately 130 grams (0.29 lbs). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The receiver shall be the Sennheiser EK 500 G4. The plug-on transmitter shall be menu-driven with a backlit LC display showing the current frequency, frequency bank and channel number, metering of AF level, lock status, pilot tone evaluation, muting function, and battery status. An auto-lock feature shall be provided to prevent settings from being accidentally altered. Some plug-on transmitter parameters such as receiving frequency, plug-on transmitter name and pilot tone setting shall be synchronizable with the associated plug-on transmitter via an integrated infrared interface. The plug-on 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. The plug-on transmitter shall feature an Audio-XLR-3F connector. Via the "PhantomPower 48V" menu item, the 48 V phantom powering for condenser microphones shall be switchable between "Active" and "Inactive". 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 plug-on transmitter shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Audio frequency response shall range from 80 - 18,000 Hz. Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 120 dBA. Total harmonic distortion (THD) shall be ≤ 0.9 %. The plug-on transmitters max. input voltage shall be 6 Veff; the unbalanced input impedance shall be 6 kΩ; the input capacitance shall be switchable. The input sensitivity shall be adjustable within a 48 dB range in steps of 6 dB. Power shall be supplied to the plug-on 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 210 mA at nominal voltage; ≤ 25 μA when plug-on transmitter is switched off. Operating time shall be typical 8 hours. The plug-on transmitter shall have a rugged metal housing; dimensions shall be approximately 105 x 43 x 43 mm (4.13" x 1.69" x 1.69"). Weight including the batteries shall beapproximately 195 grams (0.43 lbs). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F). The plug-on transmitter shall be the Sennheiser SKP 500 G4.
