I/O Modules

The Symphony I/O Mk II has a configurable chassis allowing it the flexibility for use in any environment. Two module

slots can be filled by any combination of several I/O modules providing a solution for everyone.

Mk II I/O Modules

Mk II I/O modules benefit from our most refined converter technology and engineering techniques which results in the

lowest distortion and greatest dynamic range of any A/D converter we’ve ever designed, and a more powerful &

robust D/A that maintains fidelity and punch.
