23 – Output Channel Function Indicators Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the DC-One, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. - Page 15 28 – Balanced XLR Outputs Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output channel can output different frequency ranges depending on its assignment and cross-over settings. Care must be taken to assure that each output is connected to an appropriate amplifier and loudspeaker to avoid damage or unexpected results.

Page 16: Installation
Installation For proper operation, all directions regarding installation and connection must be followed. Mounting The DC-One should be mounted in a rack-mount enclosure or rack rails. The unit is 1RU tall by 14” (353mm) deep. Proper clearance for air circulation around the unit must be provided. -
Page 17: Un-Balanced Input / Output Connections
Un-balanced Input / Output Connections Un-balanced connections can be made to the DC-One, although induced noise from cabling may be increased. Cables should also be less than 15” (5m) in length. Unbalanced connections can be 6dB lower in level as well. To match the audio level obtained with a balanced connection, it is necessary to tie pin 3 to ground at the XLR connector. -
Page 18: Usb
Connecting the DC-One to a PC for operation via the DC-One Graphic User Interface application is accomplished via the front panel USB port. The port conforms to the USB 1.0. Type B specification.
