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 (ty-
pical). 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
“High Boost” (+5.5 dB at 10 kHz). Signal-to-noise ratio at 1 mV and peak deviation shall be ≥ 115 dBA. Total harmonic dis-
tortion (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 transmitter shall be menu-driven with a backlit LC display showing the current frequency, frequency bank and chan-
nel 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 transmitter parameters shall either be configurable in the associated receiver’s menu and synchronized with the
transmitter via an integrated infrared interface or shall be programmable in the transmitter menu.
The 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 ex-
ternal 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 transmitter shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Audio fre-
quency response shall range from 80 – 18,000 Hz (microphone) or 25 - 18,000 Hz (line). 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 60 dB range in steps of 3 dB.
Power shall be supplied to the 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
transmitter is switched off. Operating time shall be typical 8 hours. The transmitter shall have a rugged metal housing;
dimensions shall be approximately 82 x 64 x 24 mm (3.23“ x 2.52“ x 0.94“). Weight including the batteries shall be appro-
ximately 160 grams (5.64 oz). Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F).
The transmitter shall be the Sennheiser SK 300 G4-RC.
