ARCHITECT‘S SPECIFICATION

A central control unit with integrated PC, control software package and digital processor is the hub of a digital discussion
system. The central control unit shall supply 52.8 V⎓ power and control data through a proprietary ADN network bus for
controlling up to 40 discussion units. The integrated control software shall be controlled using the intuitive front panel
display using multifunction control keys. Alternatively, the software can be accessed by connecting a standard VGA mon­itor, keyboard and mouse. The integrated software shall provide support in 13 languages and allow fault monitoring and
error diagnostics and full control over all delegate stations and the audio and conference parameters including equaliza­tion, feedback suppression, microphone limiting, and conference modes. An Ethernet port shall be provided for network
connection and control through third party digital control systems (Crestron, AMX, etc.). USB recording capability shall be
provided for the conferencing program audio.

A full system diagnostics check is executed upon application of power to the unit. The remote delegate discussion units
connected to the central control unit shall be hot-swappable during a conference. Addressing of the delegate discussion
units shall be done automatically by order of cabling; alternatively the addresses shall be assignable manually in the con­ference manager software. Audio input and output ports are provided as electronically balanced XLR connections. Audio
frequency response shall be 100 to 14.000 Hz. Input voltage range shall be -18 to +18 dBu (XLR In). Maximum output level
shall be +10 dBV with a signal-to-noise ratio of greater than 80 dB A-weighted at +18 dBV.

Total harmonic distortion shall be less than 0.01% A-weighted at +6 dBV In and Out. Power consumption shall be 245 W;
operating temperature shall be +5 °C to +50 °C (+41 °F to +122 °F). The central control unit shall be housed in a stand­alone desktop housing; rack mounting shall be accomplished using optional rack mounting brackets. The housing shall
measure 417 x 100 x 345 mm (16.4" x 3.94" x 13.58"). Weight shall be 6,500 g (14.3 lbs).

The central control unit shall be manufactured by Sennheiser and shall be type ADN CU1.
