The Apogee Electronics Symphony I/O Mk II Pro Tools Chassis is an audio interface chassis designed to provide direct connectivity to Pro Tools HD systems for recording and mixing engineers in broadcast, postproduction, studio, and live stage applications. It features a Mini-DigiLink port in the pre-installed HD option card, BNC loop sync I/O, and BNC word clock I/O. A stereo 1/4" headphone jack enables quick and effective monitoring with a variety of headphone impedances.
 
Emulating an Avid HD I/O interface, it ensures seamless integration and sample-accurate delay compensation while delivering ultralow latency for proper timing in signal conversion. Configure and control the chassis via the color touchscreen display and large rotary control on the front panel. Install multiple I/O cards (available separately) for up to 32 channels of analog inputs and outputs.
 
The Symphony I/O MkII is made in the USA and ships with a power cable.
