M12

The M12 builds on the design of the M1 SE D/A converter, handling and converting digital sources through a pure dual mono analogue signal path. It uses high-resolution analogue gain and level control to control the D/A converter’s output stage in the analogue domain, with no loss of resolution. Analogue inputs are passed through for analogue sources. Like the M1, the M12 is a dual mono design with 3 power supplies, separate left and right analogue
power supplies, and separate digital and analogue processing.

The M12 adds a network interface and media renderer. This allows it to appear as a DLNA device on an audio network and serve as an audio device for playback or streaming through a wired network connection. Wired data can be run over longer distances without loss in quality, allowing the network server to be positioned as required.

Analogue gain control supports DSD playback with a pure analogue DSD converter. Filtering and level control are performed in the analogue domain, with no digital signal processing. In most DACs, DSD is converted to a multi-bit sigma delta or PCM signal for filter processing. The M12 provides a pure DSD path, with post-processing for noise filtering and level control carried out entirely in the analogue domain.

The M12 provides precise, silent analogue control with 90db of range in 1db steps. It is fully remote controlled and programmable. The digital-controlled, fully balanced dual mono resistor ladder is positioned at the source, at the output of the DAC’s I-V stage. This provides digital playback with analogue control from the M12’s balanced or unbalanced inputs.
