Prism Sound Orpheus

Orpheus is a FireWire multi-track audio interface for personal recording and sound production, for professional musicians, songwriters, engineers and producers as well as recording studios, post production facilities and scoring stages. Orpheus is ideal for music and sound recording, multitracking, overdubbing, stem-based mastering, analogue summing and critical listening applications.

Orpheus provides Prism Sound’s renowned performance, sound quality and state-of-the-art clock technology in a dedicated FireWire unit compatible with both Windows (XP & Vista, ASIO & WDM) as well as MAC OS X 10.4x (Intel & PPC). Once configured with a computer, Orpheus can also operate stand-alone using its ADAT and S/PDIF or AES3 I/O. Orpheus provides Prism Sound’s renowned performance, sound quality and state-of-the-art clock technology in a dedicated FireWire unit compatible with both Windows (XP & Vista, ASIO & WDM) as well as MAC OS X 10.5 (Intel & PPC). Once configured with a computer, Orpheus can also operate stand-alone using its ADAT and S/PDIF or AES3 I/O.

Orpheus has line, microphone and instrument inputs, selectable RIAA Equalization for turntables, a built-in premium-quality monitoring mixer for each output providing for performer foldback and surround monitoring, concurrent ADAT and switchable S/PDIF or AES3 digital I/O plus support for outboard MIDI devices. Microphone inputs include MS matrix processing. High-performance digital sampling-rate conversion (SRC) is available for digital inputs or outputs. Dual headphone outputs are provided each with its own volume control, both monitoring the same headphone feed.

Orpheus signal path
Eight analogue input channels and up to 10 digital input channels are available as inputs for your audio workstation software through the host computer’s audio driver. Similarly, eight analogue output channels, up to 10 digital output channels and stereo headphone outputs can play 20 different channels. For low-latency foldback or monitoring to headphones or main outputs, each output pair (1-2, 3-4 etc or the headphone output) can optionally be driven from the built-in DSP mixer with an individual local mix of any selection of inputs through the controller applet. All analogue inputs are electronically balanced with automatic unbalanced operation. Analogue outputs are electronically balanced with ‘bootstrapping’, i.e. level is maintained if one leg is grounded.
