ARCHITECT‘S SPECIFICATION
A complete professional wireless audio system designed for setting up audio conferences with up to 24 participants in any room or space available. The system shall operate in the license-free 1.9 GHz band (frequency ranges shall be as follows: EU/ANZ: 1,880 to 1,900 MHz, US: 1,920 to 1,930 MHz, Central and South America: 1,910 to 1,920 MHz, Japan: 1,893 to 1,906 MHz) and shall have an RF output power of max. 100 mW (EIRP). The system shall offer mobile device connectivity via Bluetooth (v. 4.2 supported profiles: HFP, HSP and A2DP), NFC, as well as USB and audio cable. The system shall be comprised of four conference units (so-called satellites) powered by a rechargeable battery, a charging and transport case, an external power supply unit for the charging and transport case, plus a USB cable and an audio cable (2.5 mm jack to 3.5 mm jack) to allow for wired connections. One of the four satellites shall be designed as “master satellite” and shall feature a 2.5 mm jack socket for connecting the audio cable as well as a micro-USB socket for connecting the USB cable. Each satellite shall offer a touch panel with a microphone mute button and a volume control slider. The master satellite’s touch panel shall also feature a Bluetooth button for pairing, a USB connection button for deactivating connections, an NFC status icon (lights up when NFC is used) as well as a jack plug icon (lights up when an audio jack is connected). In addition to pairing, the Bluetooth button shall allow the user to manage calls, deactivate an existing Bluetooth connection and end a conference. Alternatively, it shall also be possible to end a conference by pressing the USB button on the touch panel.

Architect's Specification continued
The speaker of a satellite shall use a dynamic driver with a neodymium magnet. The frequency response of the speaker shall range from 200 to 9,000 Hz. The satellite shall also include two MEMS microphones, one of which shall be used for diffuse noise reduction. The microphone frequency response shall range from 200 to 12,000 Hz. Each satellite shall be powered by one Sennheiser BA 100 rechargeable Lithium-Ion battery. The rechargeable battery shall provide a talk time of up to 8 hours. The charging time of the rechargeable battery shall be up to 10 hours. The charging and transport case shall operate on 12 V DC power supplied by the NT 12-10 BW power supply unit (100-240 V AC, 50-60 Hz). The operating temperature shall range from +5 °C to +45 °C (+41 °F to +113 °F). The satellites shall be 97 mm (3.82") in diameter and 76 mm in height (2.99"), the dimensions of the charging and transport case shall be 280 x 110 x 39 mm (11.02" x 4.33" x 1.54"). Approximate weights shall be as follows: satellite incl. rechargeable battery: 449 g (0.99 lbs.), charging and transport case: 2.7 kg (5.95 lbs.).
