ARCHITECT‘S SPECIFICATION
The compact camera receiver with adaptive diversity technology shall be for use with a companion transmitter as part of
a wireless RF monitoring system.
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.
