Mute function
Integrated 5-band graphic Equalizer
Wide range of accessories adapts the
system to any requirement
Optimized PLL synthesizer and microprocessor technology
Stereo/mono selection
Easy setup of a multi-channel system
using the Easy Setup Sync function
You can only sound better if you hear yourself better. Wireless monitoring is taken
to the next level of perfection with the Sennheiser G3 monitoring system. Added
features of this stereo transmitter include the valuable integrated 5 band equalizer for extra control of the sound. New pass-through sockets for the audio signal
enable the audio feed from a console to be routed to other devices in the chain,
simplifying setup. The enhanced audio frequency response of 25 to 15,000 Hz
means the sound the performers hear is the most realistic and life-like a wireless
monitor system has
ever had to offer.

ARCHITECT’S
SPECIFICATIONS
The wireless stereo rack-mount transmitter shall be for use with a companion receiver as part of a wireless RF monitoring system.
T
he transmitter 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; transmission frequencies shall be 1,680 per range and shall be tunable in 25 kHz steps. The transmitter shall feature 20 fixed frequency banks with up to 16 compatible frequency presets and 6 user
banks with up to 16 user programmable frequencies.
Frequency stability shall be +10 ppm at −10 °C to +55 °C (+14 °F to +131°F).
RF output power at 50 O shall be switchable between 10 mW (Low) and 30 mW (Standard).
The stereo audio input shall utilize two discrete (left/right) electronically balanced 1⁄4“ (6.3 mm) jack/XLR-3F combo sockets; the
audio output shall utilize a balanced 1⁄4“ (6.3 mm) jack socket; one audio loop output shall be provided utilizing a balanced 1⁄4“
(6.3 mm) jack socket. A headphone output with headphone volume control shall be provided and shall utilize a 1⁄4“ (6.3 mm) stereo
jack socket. The transmitter shall have an Ethernet port (RJ45) for remote network-based monitoring and control using the Sennheiser Wireless System Manager software. One 50 O BNC-type input socket shall be provided for connecting the antenna.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. The transmitter shall incorporate the Sennheiser HDX compander system and
shall include a 19-kHz MPX pilot tone with a ±5 kHz deviation. The audio frequency response shall range from 25 –15,000 Hz.
Maximum input level shall be +22 dBu. Total harmonic distortion (THD) at 1 mV and nominal deviation shall be < 0.9 %. Signal-tonoise ratio at nominal load and peak deviation shall be > 90 dB.
The 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, transmission power, equalizer setting, input sensitivity, and lock status. An auto-lock
feature shall be provided to prevent settings from being accidentally altered.
The parameters of associated receivers shall be configurable in the transmitter menu and synchronized with the receivers via an
integrated infrared interface.
