18-in, 14-out audio interface complete with ADAT Lightpipe

The FireWire 18/14 is an 18-in, 14-out audio interface complete with ADAT Lightpipe for multi-channel communication with other digital devices. It features 8 x 4 analog I/O at up to 24-bit/96kHz, and boasts 192kHz on the first two inputs and all four outputs. Channels 1 and 2 also include high-quality microphone/instrument preamps. S/PDIF optical digital I/O provides 2-channel PCM, as well as pass-through of surround-encoded AC-3 and DTS material. Flexible internal mixing allows input and output routing, including an aux bus for effects send or monitor mix. A front-panel momentary switch allows allows DJ-style headphone auditioning between two assignable sources. Other features include two headphone amplifiers, assignable level controller, S/PDIF coaxial/optical digital I/O, 1 x 1 MIDI I/O, and BNC word clock connectors for synchronization to other digital devices.
