T H E X - M I X E R D I G I T A L C O N S O L E Specifications Test Conditions: Specifications are per channel. 0 dBu corresponds to 0.775 volts RMS regardless of circuit impedance. This equals 0 dBm into a 600 ohm circuit for convenient level measurements using meters calibrated for 600 ohm circuits. Noise specs based on 20 kHz bandwidth. Noise increases about 1.7 dB if a meter with a 30 kHz bandwidth is used.
T H E X - M I X E R D I G I T A L C O N S O L E Installation The X-mixer console sits on top of the studio furniture countertop. A minimum of 13 inches of vertical clearance above the countertop is required to open the operator control surface to its service position. The X-mixer console consists of: ...

T H E CABLING AND WIRING To simplify console connection, draw up a facility wiring plan listing the console‘s audio and logic connections with peripheral devices. Identify and create tags for each cable and then list each connection in a master facility wiring logbook. This facilitates initial wiring installation and future system wiring changes, equipment updates or system troubleshooting.
T H E X - M I X E R D I G I T A L C O N S O L E ANALOG AUDIO CONNECTIONS There are no analog interstage patch points within the X-mixer channels or outputs. To use a patchbay, connect the line level outputs from the peripheral devices directly to the patch bay and then normal these to the appropriate Input channels. Likewise, Xmixer‘s outputs may also be routed through a patchbay normalled to standard peripherals such as On-Air processing gear, recorders, telephone hybrids, etc.
T H E DIGITAL AUDIO CONNECTIONS All digital inputs use nine-pin AMP MR connectors. These connections input AES-3 (AES/EBU) compatible signals. All digital outputs use six-pin AMP MR connectors. These connections output AES3 (AES/EBU) compatible signals. DESCRIPTION To connect a S/PDIF digital device to an X-mixer digital input, use a 249 ohm resistor to properly terminate the S/PDIF cable. Install the resistor onto the connector per the following illustration.
T H E PERIPHERAL DEVICE LOGIC CONNECTIONS X - M I X E R D I G I T A L Peripheral Device Logic Interface (example: starting or stopping a source) Starting and Stopping Peripherals All logic outputs for the console are high current open collector logic sinks to ground. The open collector logic in the console can sink up to 50 milliamps and 12 VDC into ground. This type of open collector logic output can directly connect to many peripheral devices without an interface.

T H E X - M I X E R D I G I T A L C O N S O L E Operation The X-mixer console is designed for extreme ease of use. INPUT SOURCES The X-MIX-14-14 console has 14 source inputs :2 mic, 10 analog stereo line, 2 digital AES3. The X-MIX-14-22 console has 22 source inputs :2 mic, 10 analog stereo line, 10 digital AES3. INPUT CHANNELS The X-mixer-14 has fourteen fader chanels Through the PC setup software, any fader channel can be assigned any of the input sources.
T H E X - M I X E R D I G I T A L C O N S O L E TELCO OPERATION The X-mixer has an easy to use and yet powerful Telco system. It supports a single mix minus bus for a single phone hybrid. Any of the 10 line level source inputs can be assigned in the PC setup software utility as a Telco channel. The caller can be assigned to any ONE of the 3 main buses (Pgm, Aud, or Mono). More than one bus can not be selected because the caller’s mix minus bus must follow that bus assign ment.
T H E X - M I X E R D I G I T A L C O N S O L E CONTROL ROOM MONITOR & TIMER The console has a full featured broadcast monitoring system. It includes a control room monitor, headphones, cue, talkback, & uptimer system. The control room monitor can select between an external (usually off air) input, Program bus, Audition bus, and Mono bus. The monitor output has an individual level control. The headphones follow the monitor select switch and have an individual level control.
T H E X - M I X E R D I G I T A L C O N S O L E REMOTE LINE SELECTORS (RLS) The remote selector has two 6 position banks of switches. X-mixer-14 model For remarkable flexibility, each switch may be assigned to any of the 14 (or 22) source inputs in the console: mic, analog line, AES digital. The only limitation is that a Telco input may not be assigned to a remote selector. One powerful feature of the remote selectors is that source logic is supported if a source is assigned to the remote switch.
