PRODUCT SPECIFICATION 4/4 evolution wireless G4 SKP 500 G4 | Pro Plug-on Transmitter ARCHITECT'S SPECIFICATION The plug-on transmitter shall be for use to turn XLR-equipped microphones into wireless ones as part of a wireless RF transmission system. The plug-on 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; receiving frequencies shall be 3520 per range and shall be tunable in 25 kHz steps. The plug-on 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 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. Sennheiser electronic GmbH & Co. KG · Am Labor 1 · 30900 Wedemark · Germany · www.sennheiser.com
