The Apogee Electronics Symphony I/O Mk II Pro Tools Audio Interface with Special Edition 2x6 Analog I/O and 8x8 Digital I/O is an audio interface designed to deliver high-performance A/D and D/A conversion at up to 192 kHz for mixing and mastering engineers using Pro Tools HD systems in personal, project, and commercial studios.
 
The included 2x6 SE I/O card features stunning dynamic range with low distortion and noise for mastering-grade sonic quality.Its analog I/O includes two inputs on XLR 3-pin jacks and six outputs on a DB25 connector. Additional XLR, TOSLINK optical, and RCA coaxial jacks provide connectivity for AES/EBU, ADAT, and S/PDIF digital inputs and outputs. The chassis utilizes Mini-DigiLink connectivity for high-speed data transfer rates and compatibility with your Pro Tools HD hardware. Its front panel presents a TFT touchscreen display, multi-function control knob, and convenient 1/4" stereo headphone output.
 
Apogee Electronics Symphony I/O MkII Pro Tools HD Chassis (No I/O Modules)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, post-production, 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 ultra-low 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 thirty-two channels of analog inputs and outputs.
