ML12-2ch

Soft dB ML12-2ch Sound Masking System Controller

The Soft dB ML12-2ch is a compact, networked sound masking controller designed for small-scale AV installations such as private offices, meeting rooms, quiet zones, or focused workspaces. It features 2 independent output channels, each supporting up to 6 speakers – for a total of 12 speakers per controller.

Each channel includes a dedicated equalizer with 340 narrow bands and 23 1/3 octave bands, allowing both automatic and manual tuning. The built-in high-power amplifier delivers up to 92 dBA at 1 meter, ensuring effective sound masking even in acoustically sensitive environments.

The ML12-2ch supports 2 inputs for active volume control sensors and 4 music/paging inputs with independent 1/3 octave EQ per channel. It also includes 2 inputs for wall-mounted volume control knobs.
