Featuring easy-to-use, plug-and-play functionality, the ATUC-50 Digital Discussion System offers reliable, clear and intelligible communication to significantly increase meeting efficiency and effectiveness. The system provides 24-bit/48kHz uncompressed digital audio for natural-sounding voice reproduction, along with a 12-band feedback suppressor that enables higher volume levels. The ATUC-50CU rack-mountable control unit can power and control a total of 50 ATUC-50DU discussion units and ATUC-50INT interpretation units (max of six INTs per CU). Up to three control units may be cascade-connected via Cat5e (or better) cable. This cascade-connection thus enables the use of up to 150 discussion/interpretation units in one system. The ATUC-50CU features four balanced outputs and one unbalanced output, plus left/right AUX RCA inputs, two mic/line inputs, and two interpretation return inputs to provide simultaneous interpretation feeds in addition to the floor language feed. The ATUC-50CU is equipped with an audio recorder that can record MP3 or WAV files of 2 GB or less onto a connected USB mass storage device (2 TB max. storage capacity). When the 2 GB limit is reached, a new file can be created to continue recording. Up to four channels are available for recording WAV files; up to two channels are available for recording MP3s. The front panel of the ATUC-50CU offers several indicator LEDs to display status of USB access, recording, discussion unit power, discussion unit chain, control unit link, remote control, and audio signal level. The OLED Display shows system settings that can be adjusted by using the jog dial and back button. Among the settings are multiple modes that allow the system to adapt to any discussion situation, including Free Talk mode, Request to Talk mode, Full Remote mode, and various override settings. Automated gain control (AGC), mic gain and mic EQ settings are available for each individual discussion unit. Settings can be saved as presets and easily recalled before the start of each meeting. The control unit can also be programmed to work via Web Remote Control, which enables the user to configure and operate the system from a computer or mobile device. IP Control allows full parameter access from most third-party control systems. Each ATUC-50DU discussion unit and ATUC-50INT interpretation unit is equipped with a 3-pin XLRF-type input for use with compatible gooseneck microphones, including the ATUC-M43H or ATUC-M58H microphones specifically designed for the system. The units also feature a display for monitoring volume and channel selection, buttons for selecting channel, a built-in speaker, a headphone jack with volume control, two independently programmable LED indicators, and a talk button to turn the connected microphone on/off (button on ATUC-50DU can also be programmed to function as a request-to-talk button). On units designated by the control unit as priority discussion units, the talk button can be used to mute and override a non-priority discussion unit. Up to 50 discussion/interpretation units (max of six INTs) may be connected to a control unit, using Cat5e (or better) cable employed in either daisy chain or ring topology. Ring topology offers an additional layer of stability to the system since the system actually regards the start and end of the ring (terminated at the discussion unit chain A/B inputs on the control unit) as the start of two daisy chains. Thus, even if there is a connection failure somewhere in the ring, the control unit will still recognize each discussion unit as part of one of the two daisy chains, allowing the system to function without interruption. The discussion units are designed for tabletop or recessed mounting, and are outfitted with a paintable front plate. The ATUC-50INT interpretation unit has the same body as the ATUC-50DU, but is programmed with firmware that makes it a powerful yet easy-to-use tool for interpreters in bi- or trilingual discussion applications. The unit's selection buttons allow interpreters to monitor either the floor language or an alternate language and to output their interpretation to one of up to three different language channels that can be monitored on the ATUC-50DU units. Two ATUC-50INT units may be linked to provide hardware redundancy for a particular language feed. The ATUC-M43H and ATUC-M58H gooseneck microphones each feature a hypercardioid condenser element with double-layer pop filter, a remote-controlled LED ring, 3-pin XLRM-type connector with rubber cap to prevent mechanical vibration, and RFI-shielding technology. Designed to mount quickly and discreetly on the underside of a table or elsewhere, the ATUC-50IU integration unit gives installers the flexibility to choose the inputs and outputs best suited for a particular installation. It is equipped with two RJ45 ports for connection to other discussion system components, seven Euroblock connectors for audio and control options, and six Euroblock connectors for LED power and general-purpose input/output (GPIO). Its flexible feature set includes a mic input, speaker output, headphone output, control input (Talk On, Vol. Up, Vol. Down, Channel Select), LED status output, and GPIO. The ATLK-EXT165 link extender allows users to extend the cable runs in a system. The extender is equipped with two RJ45 ports through which it supplies DC +48V power to connected devices. It can be set to power on/off automatically in tandem with a connected control unit or to operate locally, powering on/off with the press of its Mode switch.
