SPECIFICATIONS
The handheld vocal radio microphone shall be for use with a companion receiver as part of a wireless RF transmission system.
The radio microphone shall operate within six UHF frequency ranges, each with a 42 MHz switching bandwidth: 516 – 558 MHz,
566 – 608 MHz, 626 – 668 MHz, 734 –776 MHz, 780 – 822 MHz, 823 – 865 MHz; transmission frequencies shall be 1,680 per range and shall
be tunable in 25 kHz steps.The radio microphone shall feature 20 fixed frequency banks with up to 32 compatible frequency presets and
6 user banks with up to 32 user programmable frequencies.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Frequency stability shall be
≤
±15 ppm. RF output power at 50
O
shall be
switchable between 10 mW (Low) and 30 mW (Standard).
The radio microphone 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
≥
115 dBA.
Total harmonic distortion (THD) shall be
≤
0.9 %. Input sensitivity shall be adjustable within a 48 dB range in steps of 6 dB.
The radio microphone 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 radio microphone parameters shall either be configurable in the associated receiver’s menu and synchronized with the radio
microphone via an integrated infrared interface or shall be programmable in the radio microphone menu.
Power shall be supplied to the radio microphone 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 (30 mW) at nominal voltage;
≤
25 µA when radio micro-
phone is switched off. Operating time shall be typical 8 hours. The radio microphone shall have a rugged metal housing; dimensions
shall be approximately 50 mm (1.97“) in diameter and 265 mm (10.43“) in length. Weight including the batteries shall be approxi-
mately 450 grams (15.87 oz). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131°F).
A range of microphone heads shall be available for the radio microphone.
The radio microphone shall be the Sennheiser SKM 300 G3.
The microphone head shall be a dynamic type designed for use with the ew G3 handheld radio microphones. It shall have a
cardioid pick-up pattern and a sensitivity of 2.5 mV/Pa. (Achtung: abweichende Angabe bei Sensitivity in den TD auf der Sennheiser
Website) Maximum sound pressure level shall be 154 dB SPL. The microphone head shall be the Sennheiser MMD 935-1.
