digital wireless RF transmission system.
The receiver shall operate within ten UHF frequency
ranges, with a switching bandwidth of up to 56 MHz:
470.2 – 526 MHz, 520 – 576 MHz, 552 – 607.8 MHz, 606.2
– 662 MHz, 630 – 662 MHz, 662 – 693.8 MHz, 823.2 –
831.8 MHz, 863.2 – 846.8 MHz, 925.2 – 937.3 MHz, 1785.2 –
1799.8 MHz; selectable frequencies shall be up to 2,240.
®
The receiver shall feature Bluetooth
a frequency range between 2402 and 2480 MHz for remote
controlling the devices via a control App for iOS and Android.
The audio frequency response shall be between 20 Hz and
20 kHz (-3 dB) @ 3 dBfs. Audio total harmonic distortion
(THD) shall be ≤ -60 dB for 1 kHz @ -3 dBfs input level.
Dynamic range shall be 134 dB.
The receiver shall be menu-driven with a backlit LC display
showing the current frequency, channel number, metering of RF level, metering of AF level, lock status, muting
function, mute lock status, antenna switching diversity,
app connection, gain, audio output level, menu and battery
status of the associated transmitter. An auto-lock feature
shall be provided to prevent settings from being accidentally altered.
The receiver shall feature a balanced XLR-3M audio output
with a maximum output of +18 dBu along with an unbalanced ¼“ (6.3 mm) audio output with a maximum output of
+12 dBu. Two BNC-type input sockets shall be provided for
connecting the antennas.
The receiver shall operate on 12 V power supplied from
the power supply unit or from a Sennheiser EW-D ASA antenna splitter. Power consumption shall be ≤ 300 mA. The
receiver shall have a rugged metal housing; dimensions
shall be approximately 212 x 44 x 189 mm (8.35“ x 1.73“ x
7.44“). Weight shall be approximately 1000 grams (2.2 lbs)

– 937.3 MHz, 1785.2 – 1799.8 MHz; selectable frequencies
shall be up to 2,240.
The audio frequency response shall be between 20 Hz and
20 kHz (-3 dB) @ 3 dBfs. Audio total harmonic distortion
(THD) shall be ≤ -60 dB for 1 kHz @ -3 dBfs input level.
Dynamic range shall be 134 dB.
A programmable mute switch shall be provided to mute or
unmute the audio signal.
The bodypack transmitter’s parameters shall be configurable in the associated receiver’s menu and synchronized
with the bodypack transmitter via Bluetooth Low Energy
(BLE).
Power shall be supplied to the bodypack transmitter by
two 1.5 V AA size batteries or by one Sennheiser BA 70
rechargeable battery pack. Operating time shall be typically 12 hours with a battery pack and up to 8 hours with AA
batteries.
Occupied bandwidth shall be 200 kHz. Transmit power
(radiated) shall be 10 mW ERP (1785.2 – 1799.8 MHz Range:
