(DC to 500 kHz) amplifier such as the M10 is used. To overcome this issue, the bandwidth of the M10 can be limited to 120 kHz thanks to a low pass filter that can be activated independently for any of its input. This low-pass filter is not recommended with analog sources nor with CH Precision DACs. -

Allows users to select between the different operating modes (stereo, active/passive bi-amp, monaural or bridged). With a single M10, you can only use the amplifier in stereo mode. However, with a pair of M10s there is a range of possible options, generally dictated by the matching speakers. -

It should only be used if noise floor is an audible problem. Low-pass filter The default bandwidth of the M10 is DC to 500 kHz. As some delta-sigma DACs with little output filtering can generate high frequency content that may damage loudspeaker tweeters when amplified by a wide bandwidth system, we provide the facility to add a low pass filter with a cutoff frequency of 120 kHz in the amplifier’s signal path. -
