A wireless RF transmission system designed for presentation use and other applications where maximum speech intelligibility is required.
The system shall consist of a stationary receiver, a handheld transmitter and a bodypack transmitter.
The system 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
system 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 receiver shall be menu-driven with a backlit OLED 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 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. A headphone output with headphone volume control shall
be provided and shall utilize a ¼“ (6.3 mm) stereo jack socket. The receiver shall have an Ethernet port (RJ-45) for remote
network-based monitoring and control using the Sennheiser Control Cockpit or the Sennheiser Wireless System Manager
software. 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 defeatable (off) or adjustable from 5 - 25
dBμV in steps of 2 dB.
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 ≥ 75 dB (typical). Intermodulation attenuation shall be ≥ 70 dB (typical); blocking shall be ≥ 75 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/+5.5 dB at 10 kHz) and

Handheld/Bodypack Combo Set
“High Boost” (+5.5 dB at 10 kHz). Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 115 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 350 mA. The receiver shall have a rugged metal housing; dimensions shall be approximately 202 x
212 x 43 mm (7.95“ 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 300-500 G4.
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 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.
The handheld transmitter shall be equipped with a mute switch, which shall be switchable between “AF on/off”, “RF on/
off”, “Push to mute”, “Push to talk” 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 switchable between 10 mW (typical, low) and 30 mW (typical, standard) and 50 mW (typical, high).
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 ≥ 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.
Power shall be supplied to the handheld 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 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 300 G4-S.
The bodypack 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 bodypack transmitter parameters shall either be configurable in the associated receiver’s menu and synchronized
with the bodypack transmitter via an integrated infrared interface or shall be programmable in the bodypack transmitter
menu.
The bodypack transmitter shall be equipped with a mute switch, which shall be switchable between “AF on/off”, “RF on/
off” and “Disabled” via the receiver’s user interface. A 2.5 mm jack socket shall be provided for connecting a Sennheiser
RMS 1 external mute switch. The settings for the external mute switch shall be switchable between “AF on/off”, “RF on/
off”, “Push to mute” and “Push to talk” 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 switchable between 10 mW (typical, low) and 30 mW (typical, standard) and 50 mW (typical, high).
The bodypack transmitter shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch.
