RME Digiface USB 66-Channel ADAT to USB Optical Audio Interface

The Digiface USB offers four optical ADAT / S/PDIF I/Os and a high-quality analog line/phone stereo output via a 1/4 TRS jack, for a total of 32 inputs and 34 outputs when using ADAT optical. It also comes with the real-time mixer software TotalMix which allows you to mix and route all inputs and playback channels simultaneously, to any hardware outputs. The software features a dedicated Control Room section with Talkback, Main/Phones, fader groups, mute groups, complete remote controllability via Mackie or OSC protocol, and more.

The included DIGICheck utility software provides a suite of tools to test, measure, and analyze digital audio streams with a high-precision peak/RMS level meter, a spectral analyzer, a vector audio scope, and more.

• Interface: USB 2.0, bus-powered, no external power supply required
• Sample rates: 28 kHz to 200 kHz
• 66 channels: 32 in / 34 out
• 4 x ADAT / S/PDIF optical input ports
• 4 x ADAT / S/PDIF optical output ports
• Standard speed: 32 channels, 24-bit/up to 48 kHz, record/playback via ADAT optical
• Double speed: 16 channels, 24-bit/96 kHz, record/playback via ADAT optical (S/MUX)
• Quad speed: 8 channels, 24-bit/192 kHz, record/playback via ADAT optical (S/MUX4)
• Each single optical port can use either ADAT (up to 8 channels) or S/PDIF (stereo)
• ADAT and S/PDIF I/Os can be used simultaneously
• One analog line/headphone stereo output, provides separate output for independent submix
• All settings can be changed in real-time
• TotalMix allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any hardware outputs, with 46-bit internal resolution
• TotalMix for latency-free submixes and ASIO Direct Monitoring
• Compact, portable, and lightweight audio interface
• Slave and master clock modes - Internal, ADAT input, S/PDIF input
• Buffer sizes/latencies 32 to 8192 samples, selectable
• Automatic and intelligent master/slave clock control
• SteadyClock: Jitter-immune, super-stable digital clock
• SyncAlign guarantees sample-aligned and never-swapping channels
• SyncCheck tests and reports the synchronization status of input signals
• DIGICheck DSP: Level meter in hardware with peak and RMS calculation
• High-resolution Bitclock PLL (audio synchronization) in ADAT mode, even in vari-speed operation
• Near-zero effective clock jitter influence on A/D and D/A conversion
• PLL ensures zero dropout, even at more than 100 ns jitter
• Low-Jitter Design: < 1 ns in PLL mode, all inputs
• Driver CD contains drivers for Windows Vista / 7 / 8 / 10 and Mac OS X (x86 Intel)
