About the Symphony IO
The ADD-POWR Symphony I/O is a passive harmonic-resonance conditioner for digital audio and network connections, not an AD/DA converter or modular audio interface. It provides pass-through connections for USB and Ethernet signals and applies selectable low, medium, or high harmonic-resonance treatment to the signal path. The unit uses an external power supply and is intended for audio/video systems and professional or consumer environments.
