ARCHITECT'S
SPECIFICATIONS
The handheld vocal radio microphone shall
be for use with a companion receiver as
part of a wireless RF transmission system.
The radio microphone 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; transmissi-
on frequencies shall be 1,680 per range and
shall be tunable in 25 kHz steps. The radio
microphone shall feature 20 fixed frequency
banks with up to 12 compatible frequency
presets and 1 user bank with up to 12 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 30 mW (typical).
The radio microphone shall incorporate
the Sennheiser HDX compander system
and a defeatable pilot tone squelch. Audio
frequency response shall range from
80 – 18,000 Hz. Signal-to-noise ratio at 1 mV
and peak deviation shall be ≥ 110 dBA.
Total harmonic distortion (THD) shall be
≤ 0.9 %. Input sensitivity shall be adjustable
within a 48 dB range in steps of 6 dB.
The radio microphone shall be menu-driven
with a backlit LC display showing the cur-
rent frequency, frequency bank and channel
number, metering of AF level, transmission
status, lock status, pilot tone transmission,
muting function, and battery status. An au-
to-lock feature shall be provided to prevent
settings from being accidentally altered.
The radio microphone parameters shall be
programmable in the radio microphone
menu. Receiver parameters such as receiving
frequency, receiver name and pilot tone
setting shall be synchronizable with the
radio microphone via an integrated infrared
interface.
