ARCHITECT‘S SPECIFICATION
A wireless RF transmission system designed for presentation use and other applications where maximum speech intelligibility is required.
The system shall consist of a stationary receiver and a wireless boundary microphone.
Operating in the license-free 1.9 GHz band (frequency ranges are between 1,880 and 1,930 MHz, depending on country-specific regulations), the system shall use automatic frequency management to determine the best free available frequency and to automatically start the transmission. Additionally, the system shall incorporate automatic interference management, allowing the transmitter and receiver to move to an undisturbed, compatible frequency with no audio signal interruption, should interference occur. Furthermore, advanced 256-bit AES encryption shall be used for secure wireless transmission.
The system’s AF frequency response shall range from 20 – 20,000 Hz. The dynamic range shall be > 120 dB(A). Total harmonic distortion (THD) at 1 kHz shall be typical 0.1 %. Signal-to-noise ratio shall be > 90 dB(A). Latency shall be 19 ms. Operating temperature shall range from -10 °C to +55 °C (+14 °F to +131 °F).
The user interface of the receiver shall be operated by jog dial and OLED display. The receiver shall have dedicated pairing, escape and power buttons.
The receiver shall feature a low-cut filter as well as speech-optimized sound profiles or custom settings with a 7-band graphic equalizer. The receiver’s RF sensitivity shall be -90 dBm. RF output power of the receiver’s back channel shall be adaptive and up to 250 mW (country-specific). The receiver’s audio output shall utilize a balanced XLR-3M socket with a maximum output of +18 dBu along with two unbalanced RCA sockets with a maximum output of +6 dBu. The receiver shall feature automatic gain optimization. Two reverse SMA sockets shall be provided for connecting the antennas. The receiver shall feature RJ-45 network connectivity compatible with IPv4 and IPv6 networks. For remote control the receiver shall have media control protocol integration.
The receiver shall operate on 12 V DC power supplied from the NT 12-4C power supply unit (100-240 V AC, 50/60 Hz, for use in the USA, the UK, and Europe) or the NT 2-3 power supply unit (100-240 V AC, 50/60 Hz, for use in countries other than the USA, the UK, and Europe). Power consumption shall be 350 mA. The dimensions shall be approximately 168 x 212 x 43 mm (6.61" x 8.35" x 1.69"). Weight shall be approximately 828 grams (1.83 lb.).
The receiver shall be the Sennheiser SL Rack Receiver DW.
The wireless boundary layer microphone shall be optimized for speech transmission in conference rooms. The boundary layer microphone shall be powered by
one Sennheiser Lithium-Ion rechargeable Accupack with a typical operating time of 13 hours and shall support wireless charging as well as charging via USB. In addition, the boundary layer microphone shall be capable of being remotely controlled and monitored via the Sennheiser Control Cockpit software.
RF output power shall be adaptive and up to 250 mW
(country-specific). The AF frequency response shall range from 40 – 20,000 Hz. The maximum input level shall be 1.7 Vrms and input impedance shall be 30 k?. The boundary layer microphone shall have automatic sensitivity adjustment.
Dimensions shall be 114 x 85.3 x 30.8 mm (4.49" x 3.36" x 1.21"). Weight (without Accupack) shall be approximately 208 grams. Operating temperature shall range from 10 °C to 45 °C (50 °F to 113 °F).
The wireless boundary layer microphone shall be the Sennheiser SL Boundary 114 - S DW.
The wireless RF transmission system shall be the Sennheiser SpeechLine Boundary Set DW.
