Rack-mount receiver
Sennheiser understands that the more self-reliant a device is, the more artistic
freedom there is to enjoy. With this in mind, this new receiver has a built-in Ethernet port for remote PC monitoring and setup with Sennheiser’s Wireless System
Manager software. This receiver’s wireless sync function makes it a breeze to link
up any G3 transmitter with the unit. In addition, it has a large back-lit graphic
display where receiver and transmitter information can be easily seen even on the
darkest of stages.

ARCHITECT’S
SPECIFICATIONS
The rack-mount receiver with true diversity technology shall be for use with a companion transmitter as part of a wireless RF transmission 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 24 compatible frequency presets and 6 user banks with
up to 24 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. A headphone output with headphone volume control shall be provided and shall
utilize a 1⁄4“ (6.3 mm) stereo jack socket. The receiver shall have an Ethernet port (RJ45) for remote network-based monitoring and
control using the Sennheiser Wireless System Manager software. Two 50 O 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, equalizer setting, output gain, muting function, transmitter type 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.
The parameters of associated transmitters shall be configurable in the receiver menu and synchronized with the transmitters via an
integrated infrared interface.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Squelch threshold shall be defeatable (off) or adjustable adjustable from
5 – 25 dBμV in 2 dB steps.
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 ≥ 75 dB (typical). Intermodu­
lation 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/+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 ≥ 115 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 2-3 mains unit. 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 G3.
