ARCHITECT‘S SPECIFICATION
A wireless RF transmission system consisting of a stationary receiver and a handheld transmitter includings a microphone head.
The system 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; receiving frequencies shall be 1,680 per range and
shall be tunable in 25 kHz steps. The system 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, pilot tone evaluation, muting function, and battery status
of the associated transmitter. An auto-lock feature shall be provided to prevent settings from being accidentally altered.
The receiver shall feature an integrated guitar tuner and shall provide a sound check mode.
Some receiver parameters such as receiving frequency, receiver name and pilot tone setting shall be synchronizable with
the associated transmitter via an integrated infrared interface.
The receiver shall feature a balanced XLR-3M audio output with a maximum output of +18 dBu along with an unbalanced
¼" (6.3 mm) audio output with a maximum output of +12 dBu. The receiver shall have two DATA ports (RJ 10) to set up a
multichannel system. Two BNC-type input sockets shall be provided for connecting the antennas. 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 < 2 μV 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. Four selectable equalizer presets
shall be provided: “Flat”, “Low Cut” (−3 dB at 180 Hz), “Low Cut/High Boost” (−3 dB at 180 Hz/+6 dB at 10 kHz) and “High
Boost” (+6 dB at 10 kHz). 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 48 dB range in steps of 3 dB.
The receiver shall operate on 12 V power supplied from the NT 2-3 CW mains unit (for 100 – 240 V AC, 50/60 Hz). Power
consumption shall be 300 mA. The receiver shall have a rugged metal housing; dimensions shall be approximately 190 x
212 x 43 mm (7.48" x 8.35" x 1.69"). Weight shall be approximately 980 grams (2.16 lbs). Operating temperature shall range
from −10 °C to +55 °C (+14 °F to +131 °F).
The receiver shall be the Sennheiser EM 100 G4.
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. Receiver parameters such as receiving frequency, receiver name and pilot tone setting shall be synchronizable with the radio
microphone via an integrated infrared interface.
The handheld vocal radio microphone shall be equipped with a mute switch, which shall be switchable between “AF on/
off”, “RF on/off” and “Disabled” 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 30 mW (typical).
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 ≥ 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 radio microphone by two 1.5 V 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 radio microphone 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 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 radio microphone.
The radio microphone shall be the Sennheiser SKM 100-S G4.
