Apogee Symphony I/O Mk II Thunderbolt (8X8)

The Apogee Electronics Symphony I/O Mk II SoundGrid Chassis with 8x8 Analog I/O and 8x8 Digital I/O is a SoundGrid-compatible audio interface designed to deliver flexible inputs and outputs and Ethernet connectivity to computers and SoundGrid devices for recording and mixing engineers in broadcast, post-production, studio, and live stage applications. The included I/O card provides eight channels of analog inputs and outputs via DB25 connectors, eight channels of AES/EBU and optical digital I/O, and stereo S/PDIF.

Its RJ45 port and BNC word clock I/O ensure simple hook-up of SoundGrid compatible devices, and the stereo 1/4" headphone jack enables efficient and consistent monitoring with headphones of varied impedances. Ultra-low latency operation allows for A/D and D/A conversion without distracting delay. Connect a SoundGrid server (available separately) to record and mix with your SoundGrid-compatible plug-ins without taxing your computer's CPU. Configure and control the Symphony via the free SoundGrid Studio app or utilize the color touchscreen display and large rotary control on the front panel.
