Apogee Symphony I/O Mk II 8x8+8MP Thunderbolt Audio Interface

Loaded with a Connect 8x8 Mic Pre module, this Symphony I/O MkII offers 8 preamps with Apogee's Advanced Step Gain Architecture for 72 dB of pristine gain.

The Apogee Symphony I/O Mk II 8x8+8MP Thunderbolt audio interface delivers Symphony-quality sound with robust, high-performance AD/DA converters and Apogee's Advanced Step Gain Architecture mic preamps at an unprecedented price. Using cutting edge components and a simplified, optimized analog circuit design, Apogee engineers are able to place more AD/DA converters and mic preamps on a single module board. The result is a single Symphony I/O Mk II with 8 mic preamps (expandable to 16) at an unprecedented price for Symphony Quality and an extremely competitive price for the market. With industry leading sound quality and scalable Thunderbolt I/O, the Symphony Connect series is the ideal choice for broadcast, live sound, education, post, house of worship and recording studio facilities.

Symphony I/O Mk II is a multi-channel audio interface featuring Apogee's flagship AD/DA conversion, modular I/O, intuitive touchscreen display and optional world-class microphone preamps. Designed to deliver professional sound quality for audio recording, mixing and mastering, Symphony I/O Mk II is the ultimate music production centerpiece for any modern studio.

This version of the Symphony I/O Mk II includes Thunderbolt I/O. With its option card flexibility, Symphony I/O Mk II can provide direct connectivity to one of 4 different platforms - Thunderbolt(TM), Pro Tools(R) HD, Dante(TM)+ Pro Tools(R) HD, or Waves SoundGrid network.

Apogee engineers have made it their passion to improve every flagship read more product by using the latest in electrical components and designing optimized circuitry that often exceeds the expectations of the component manufacturer. The Apogee Symphony I/O Mk II is the culmination of this 30 year commitment and raises the bar on all Apogee products before it with even better audio clarity and sonic transparency. In fact, when equipped with either the 8 or 16 modules, Symphony I/O Mk II outperforms all other multi-channel audio interfaces available for Pro Tools HD, network or Thunderbolt based systems, making it the flagship audio interface for the entire professional audio industry and the obvious choice for countless GRAMMY winning artists, producers, songwriters and engineers.
