PRODUCT SPECIFICATION 4/4 evolution wireless G4 SK 300 G4-RC | Bodypack Transmitter ARCHITECT'S SPECIFICATION The compact bodypack transmitter shall be for use with a companion receiver as part of a wireless RF transmission system. The bodypack transmitter 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; transmission frequencies shall be 3520 per range and shall be tunable in 25 kHz steps. The bodypack transmitter 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 bodypack 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 bodypack transmitter parameters shall either be configurable in the associated receiver's menu and synchronized with the bodypack transmitter via an integrated infrared interface or shall be programmable in the bodypack transmitter menu. The bodypack 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 bodypack 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 bodypack 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 bodypack transmitter is switched off. Operating time shall be typical 8 hours. The bodypack 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 bodypack transmitter shall be the Sennheiser SK 300 G4-RC. Sennheiser electronic GmbH & Co. KG · Am Labor 1 · 30900 Wedemark · Germany · www.sennheiser.com
