The Orpheus installer for Windows always included 64-bit versions which could be used with XP 64-bit edition. Following extensive tests by Prism Sound's research and development team, the company can confirm that Orpheus fully supports Vista64, allowing seamless integration with the latest 64-bit Digital Audio Workstations.
Graham Boswell, Prism Sound's sales director, says: "The main advantage of using 64-bit processing is that users can access more RAM; Vista64 allows up to 128GB RAM. This means ou can run more plug-ins and applications than as possible before. In addition, applications that are specifically optimised for 64-bit processors show a significant increase in performance. Orpheus users can now take full advantage of these benefits."
Launched in 2007, Orpheus is a 1U, 19-inch rackmount 192kHz-capable unit that is designed to appeal to both recording professionals and serious project studio owners. With Orpheus, Prism Sound has succeeded in creating a computer-based Firewire interface that retails at an attractive price point without sacrificing many of the features and the quality of its top-of-the-range products, like the ADA-8XR.
Orpheus offers eight simultaneous balanced analogue inputs, four line-level jack inputs and four auto-sensing mic/line Neutrik combi jacks that will accept either jack or XLR connectors. The high-quality mic preamps allow the signal at the mic-level inputs to be boosted by up to 60dB (in 1dB increments), and each analogue input has its own adjustable patented Prism Sound Overkiller built in, to prevent signal overloads before the A-D conversion stage. There are also a switchable SPDIF/AES-EBU stereo digital input and an eight-channel ADAT optical input, allowing the Orpheus to handle a maximum of 18 simultaneous inputs to a computer-based recording system hooked up to the unit's main Firewire connector. A built-in mixer is included, driving eight analogue outputs, allowing users to monitor input signals with zero latency, insert analogue summing mixers, or control multiple stereo or multi-channel monitoring systems directly from Orpheus. Prism Sound's respected high-quality, low-jitter digital clock source is also built in, along with synchronous sample-rate conversion and SNS noise-shaping, permitting accurate real-time reclocking or sample-rate conversion, or high-quality dithering of 24-bit material down to 16-bit for CD mastering.
Orpheus is fully software-controllable via a cross-platform control application (available for PCs running Windows XP, Vista or Macs running OS X). This makes it ideally suited to computer-based musicians who want to work with modern computer-based DAWs but wish to maintain the quality of signals from analogue recording sources or processors in the digital production environment.
"As 64-bit processing is taken up across the industry, DAWs will be able to record and playback more channels simultaneously â€“ the perfect complement to a rack of daisy-chained Orpheus units," Boswell adds.
