Prism Sound Orpheus ADC/DAC【税込定価 850,5000円】Prism Sound 社は 妥協のないサウンドクオリティー基準をもつ数少ないトップブランドメーカーで、世界最高水準の高音質アナログ <=> デジタルオーディオインターフェースメーカ として有名です。 弊店では更なる高音質を求めて Mackie Onyx 1200F Studio Recording Preamp から この最高級 Orpheus ADC/DAC 【税込定価 850,500円】 にグレードアップしました。 2010年4月現在、これほど高額高音質な ADC/DAC オーディオインターフェース を使用している同業他店はなく 音質における追随を許しておりません。
レコードからCDに変換する場合は、アナログの音源取り込み時に細心の注意と十二分の機材を投入する必要がありますが、この万全の注意を払って得たアナログ信号をデジタル化する際に要となるのが この ADC/DAC オーディオインターフェースです。Prism Sound Orpheus はプロダクション、パーソナルスタジオ、作曲・編曲家、エンジニアやプロデューサーは勿論、レコーディングスタジオやポストプロダクション等にも対応しており、あらゆる音楽製作工程に必要な機能を装備しています。
| 8chアナログ入力（4mic/Line + 4Line）と10chデジタル入力（ADAT +S/PDIF）がホストコンピューターのDAWソフトウェアにオーディオ入力として使用可能なだけではく、出力は、8chアナログ（8Line）と10chデジタル（ADAT
+ S/PDIF）、及び2つのステレオヘッドフォン出力で合計22chの同時出力が可能です。 音質ですが、従来メイン機材として使用してきた Mackie Onyx 1200F Studio Recording Preamp も十分高音質ですが、それにに加えて 更に磨きがかかった音で、低域から高域までそのフラットな特性には感嘆するしかありません。 まさに 「音がそこにある」 という臨場感を経験するともはや後戻りはできなくなります。 |

Overview 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 10.4.11 and later (Intel & PPC). Once configured with a computer, Orpheus can also operate stand-alone using its 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. |

No-compromise, full Prism Sound audio quality Orpheus makes no compromises on audio quality. It is the result of years of research and development into digital audio conversion and extensive dialogue with Prism Sound's customers.  The
Orpheus design brief was: Get Prism Sound quality conversion and mic preamps
into a 1U box at a more accessible price point. Sound quality just wasn't
negotiable. Orpheus has the same no-compromise analogue front and back ends,
with the same fully-balanced-throughout architecture, the same isolation
barriers protecting the analogue from digital and computer interference.
Orpheus draws on Prism Sound's years of experience in developing digital audio products, including its range of audio test equipment, adopted by a wide variety of clients across the audio industry from pro-audio to consumer electronics. This experience means that Orpheus is well-behaved both as a computer peripheral and an audio processor. Reliability is vitally important in professional recording. Prism Sound has always made extensive use of precise software calibration techniques in its converters - pots and tweaks are always unreliable, so there are none. The design team has gone to great lengths to minimise noise and interference, in particular hum. All of the analogue circuits have galvanic isolation, while the unit's electronically balanced I/O allows it to handle common mode interference sources as well as enabling trouble-free connection to unbalanced equipment. It is often said that THD+N figures do not always correlate well with the perception of sound quality and this is true - partly because the traditional measures of THD+N or SINAD expressed as RMS figures are rather a broad measure. With this in mind, we have taken great care to make sure that not only is the Orpheus noise and distortion spectrum beyond reproach, but the RMS distortion result measures up to the state of the art. |
