With its improved design and new features, this rugged G3 rack receiver is ready
for the road with its proven transmission reliability and inspiring flexibility. The
sound check mode allows you to check the audio and RF signal at any time during
setup. 20 frequency banks with 12 preset frequencies each, plus a user-program-
mable bank mean you can easily run multiple channels of G3 wireless simultane-
ously.

ARCHITECT’S
SPECIFICATIONS
The stationary receiver with true diversity technology shall be for use with a companion transmitter as part of a wireless RF trans-
mission system.
The receiver shall operate within six UHF frequency ranges, each with a 42 MHz switching bandwidth: 516–558 MHz, 566– 608 MHz,
626–668 MHz, 734–776 MHz, 780– 822 MHz, 823 – 865 MHz; receiving 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 feature a balanced XLR-3M audio output with a maximum output of +18 dBu along with an unbalanced 1⁄4“ (6.3 mm)
audio output with a maximum output of +12 dBu. Two BNC-type input sockets shall be provided for connecting the antennas.
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.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Squelch threshold shall be defeatable (off) or 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 dBArms S/N with HDX engaged at peak deviation. Adjacent channel rejection shall be ≥65 dB (typical). Intermodu-
lation 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 dB. 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 2-1 mains unit (for 110 V AC or 230 V AC, 50/60 Hz) or the NT
2-3 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 G3.
