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. The transmitter shall feature 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with
up to 32 user programmable frequencies.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Frequency stability shall be
≤
±15 ppm. RF output power at 50
O
shall 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.
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 k
O
unbalanced (microphone) or 1 M
O
(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 1.5 V 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.
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 160 grams (5.46 oz). Operating temperature shall
range from −10 °C to +55 °C (+14 °F to +131°F). The transmitter shall be the Sennheiser SK 500 G3.
