ARCHITECT‘S SPECIFICATION
A wireless RF transmission system designed for presentation use and other applications where maximum speech intelli-
gibility is required.
The system shall consist of a stationary receiver, a handheld transmitter and a bodypack transmitter.
The system shall operate within ten UHF frequency ranges, with a switching bandwidth of up to 88 MHz: 470 – 558
MHz, 520 – 558 MHz, 558 – 608 MHz, 558 – 626 MHz, 606 – 678 MHz, 626 – 698 MHz, 718 – 790 MHz, 790 – 865 MHz,
806 – 810 MHz, 925 – 937.5 MHz; receiving frequencies shall be 3520 per range and shall be tunable in 25 kHz steps. The
system shall feature 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32
user programmable frequencies.
The receiver shall be menu-driven with a backlit OLED display showing the current frequency, frequency bank and chan-
nel number, metering of RF level, metering of AF level, lock status, pilot tone evaluation, muting function, and battery
status of the associated transmitter. An auto-lock feature shall be provided to prevent settings from being accidentally
altered. The receiver shall provide a sound check mode.
Some receiver parameters such as receiving frequency, receiver name and pilot tone setting shall be synchronizable with
the associated transmitter via an integrated infrared interface.
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. A headphone output with headphone volume control shall
be provided and shall utilize a ¼“ (6.3 mm) stereo jack socket. The receiver shall have an Ethernet port (RJ-45) for remote
network-based monitoring and control using the Sennheiser Control Cockpit or the Sennheiser Wireless System Manager
software. Two BNC-type input sockets shall be provided for connecting the antennas.
Nominal/peak deviation shall be ±24 kHz/±48 kHz. Squelch threshold shall be defeatable (off) or adjustable from 5 - 25
dBμV in steps of 2 dB.
The receiver shall incorporate the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity
shall be < 2 μV for 52 dBA eff S/N with HDX engaged at peak deviation. Adjacent channel rejection shall be ≥ 75 dB (ty-
pical). Intermodulation attenuation shall be ≥ 70 dB (typical); blocking shall be ≥ 75 dB. Four selectable equalizer presets
shall be provided: “Flat”, “Low Cut” (−3 dB at 180 Hz), “Low Cut/High Boost” (−3 dB at 180 Hz/+5.5 dB at 10 kHz) and
