ARCHITECT‘S SPECIFICATION
A wireless RF transmission system shall consist of a camera receiver and a handheld transmitter with a cardioid dynamic
microphone head.
The receiver 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 receiver 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 1.5V AA size batteries or by one Sennheiser BA 2015 rechargeable ac-
cupack. 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; dimen-
sions 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 handheld transmitter shall operate within twelve 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, 1785 – 1800 MHz; transmission frequencies shall be 1,680 per
range and shall be tunable in 25 kHz steps. The handheld transmitter 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 handheld 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 handheld transmitter parameters shall either be configurable in the associated receiver’s menu and synchronized
with the handheld transmitter via an integrated infrared interface or shall be programmable in the handheld transmitter
menu. Receiver parameters such as receiving frequency, receiver name and pilot tone setting shall be synchronizable
with the handheld transmitter via an integrated infrared 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 handheld 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 ≥ 110
dBA. Total harmonic distortion (THD) shall be ≤ 0.9 %. Input sensitivity shall be adjustable within a 48 dB range in steps of
6 dB.
Power shall be supplied to the handheld transmitter by two 1.5V AA size batteries or by one Sennheiser BA 2015 rechar-
geable accupack. Nominal voltage shall be 2.4 V, current consumption shall be typical 180 mA at nominal voltage; ≤ 25
μA when handheld transmitter is switched off. Operating time shall be typical 8 hours. The handheld transmitter 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 approximately 450 grams (0.99 lbs). 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 handheld transmitter.
The handheld transmitter shall be the Sennheiser SKM 100 G4.
