Architect's Specification
A wireless RF monitoring system consisting of a stereo rack-mount transmitter and a compact monitoring receiver.

The transmitter operates within nine UHF frequency ranges, with a switching bandwidth of up to 42 MHz: 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 566 - 608 MHz, 606 - 648 MHz; receiving frequencies are 1,680 per range and are tunable in 25 kHz steps. The transmitter features 20 fixed frequency banks with up to 16 compatible frequency presets and 6 user banks with up to 16 user programmable frequencies.

The transmitter is menu-driven with a backlit OLED display showing the current frequency, frequency bank and channel number, metering of AF level, transmission status, transmission power, equalizer setting, input sensitivity, and lock status. An auto-lock feature is provided to prevent settings from being accidentally altered.

The parameters of associated receivers are configurable in the transmitter menu and synchronized with the receivers via an integrated infrared interface.

Frequency stability is +/-10 ppm. RF output power at 50 Ohm is switchable between 10 mW (low), 30 mW (standard) and 50 mW (high).

The stereo audio input utilizes two discrete (left/right) electronically balanced 1/4" (6.3 mm) jack/XLR-3F combo sockets; the audio output utilizes a balanced 1/4" (6.3 mm) jack socket; an audio loop output is provided utilizing two balanced 1/4" (6.3 mm) jack sockets. A headphone output with headphone volume control is provided and utilizes a 1/4" (6.3 mm) stereo jack socket. The transmitter has an Ethernet port (RJ-45) for remote network-based monitoring and control using the Sennheiser Wireless System Manager software. One 50 Ohm BNC-type input socket is provided for connecting the antenna.

Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. The transmitter incorporates the Sennheiser HDX compander system and includes a 19-kHz MPX pilot tone with a +/-5 kHz deviation. The audio frequency response ranges from 25 -15,000 Hz. Maximum input level is +22 dBu. Total harmonic distortion (THD) at 1 mV and nominal deviation is < 0.9 %. Signal-to-noise ratio at nominal load and peak deviation is > 90 dB.

The transmitter operates on 12 V power supplied from the NT 2-3 mains unit (for 100 - 240 V AC, 50/60 Hz). Power consumption is 350 mA. The transmitter has a rugged metal housing; dimensions are approximately 202 x 212 x 43 mm (7.95" x 8.35" x 1.69"). Weight is approximately 980 grams (2.16 lbs). Operating temperature ranges from -10 Degree C to +55 Degree C (+14 Degree F to +131 Degree F).

The transmitter is the Sennheiser SR IEM G4.

The receiver operates within nine UHF frequency ranges, with a switching bandwidth of up to 42 MHz: 470 - 516 MHz, 516 - 558 MHz, 520 - 558 MHz, 626 - 668 MHz, 734 - 776 MHz, 780 - 822 MHz, 823 - 865 MHz, 566 - 608 MHz, 606 - 648 MHz; transmission frequencies are 1,680 per range and are tunable in 25 kHz steps. The receiver features 20 fixed frequency banks with up to 16 compatible frequency presets and 6 user banks with up to 16 user programmable frequencies.

The receiver is menu-driven with a backlit LCD display showing the current frequency, frequency bank and channel number, metering of RF level, metering of AF level, lock status, battery status, muting function or audio channels, and pilot tone evaluation. An auto-lock feature is provided to prevent settings from being accidentally altered.

The receiver parameters is either configurable in the associated transmitter's menu and synchronized with the receiver via an integrated infrared interface or is programmable in the receiver menu.

The earphone output utilizes a 3.5 mm stereo jack socket with an output level of 2.4 V with 5 % THD at nominal deviation and an output power of 2x 100 mW at 32 Ohm.

Nominal/peak deviation is +/-24 kHz/ +/-48 kHz. Squelch threshold is defeatable (off) or adjustable from 5 - 25 dBmicroV in steps of 2 dB.

The receiver incorporates the Sennheiser HDX compander system and a defeatable pilot tone squelch. Sensitivity is < 4 microV, 1.6 microV (typical) for 52 dBArms S/N with HDX engaged at peak deviation. Adjacent channel rejection is >= 65 dB (typical). Intermodulation attenuation is >= 70 dB (typical); blocking is >= 80 dB.

Signal-to-noise ratio at 1 mV and peak deviation is approx. 90 dB. Total harmonic distortion (THD) is <= 0.9 %. The earphone output utilizes a 3.5 mm stereo jack socket with an output level of 2.4 V with 5 % THD at nominal deviation and an output power of 2x 100 mW at 32 Ohm.

The receiver includes a switchable High Boost and a multi-level limiter. The High Boost is +8 dB at 80 kHz. The limiter is adjustable from -18 dB to -6 dB in 6 dB steps or defeatable (off). The receiver provides two audio output modes, stereo or Focus, and an adjustable balance.

Power is supplied to the receiver by two 1.5V AA size batteries or by one Sennheiser BA 2015 rechargeable accupack. Nominal voltage is 2.4 V, current consumption is typical 140 mA at nominal voltage; <= 25 microA when receiver is switched off. Operating time is approximately 4 to 6 hours (depending on volume level). The receiver has a rugged metal housing; dimensions are approximately 82 x 64 x 24 mm (3.23" x 2.52" x 0.94"). Weight including the batteries is approximately 125 grams (0.28 lbs). Operating temperature ranges from -10 Degree C to +55 Degree C (+14 Degree F to +131 Degree F).

The receiver is the Sennheiser EK IEM G4.
