SPECIFICATIONS
The compact bodypack transmitter shall be
for use with a companion receiver as part of
a wireless RF transmission system.
The 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.

While it is ready for operation right out of the box, the
SK 300 G3 easily receives settings from the receiver via
its enhanced wireless sync function. This transmitter
also sets itself apart from others due to its unparalleled
mute options. If you want to quickly and easily interrupt
the sound signal at some point: you can simply attach
the optional external mute button to the additional
2.5 mm jack socket. This mute option is easily program-
med to provide a variety of mute options.

ARCHITECT’S
SPECIFICATIONS
The transmitter shall feature 20 fixed frequency banks with up to 24 compatible frequency presets and 6 user banks with up to 24 user
programmable frequencies.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Frequency stability shall be ≤ ±15 ppm.
RF output power at 50 Oshall be switchable between 10 mW (low) and 30 mW (standard). The transmitter shall incorporate the
Sennheiser HDX compander system and a defeatable pilot tone squelch. The microphone/line input shall utilize a lockable 3.5 mm jack
socket. A 2.5 mm jack socket shall be provided for connection of the Sennheiser RMS 1 external mute switch.
The audio frequency response shall range from 80–18,000 Hz (microphone) or 25–18,000 Hz (line). Maximum input voltage shall be
3 Vrms (microphone/line). Input impedance shall be 40 kOunbalanced (microphone) or 1 MO(line). The input sensitivity shall be adjus-
table within a 60 dB range in steps of 3 dB. Signal-to-noise ratio at 1 mV and peak deviation shall be ≥115 dBA. Total harmonic distortion
(THD) shall be ≤0.9 %. 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, 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.
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 (30 mW) at nominal voltage; ≤25µA when transmitter is switched off.
