Important Notes
Passive speakers, powered subwoofer, speaker cables, and additional source components are sold separately. A turntable requires a built-in or external phono preamplifier before connecting to the analog input. Dolby decoding supports playback through the M1’s stereo speaker system; additional surround-speaker amplification is not provided.
Dirac Live requires a separately purchased license and appropriate measurement equipment. Keep firmware updated for supported features. Streaming services may require subscriptions, and availability varies by region.
