SETTING BASS PEAK LIMITERS

SETUP SPEAKERS MANUAL LEVELS CALIBRATION BASS PEAK LIMITERS

Selecting the LEVELS CALIBRATION menu BASS PEAK LIMITERS option opens the BASS PEAK LIMITERS menu shown below, which can be used to set amplitude limits for low-frequency signals sent to the Main Zone audio output connectors labeled Subwoofer L/R and LFE as well as low-frequency signals redirected to other Main Zone audio output connectors. The MC-12 is equipped with an internal limiter that prevents low-frequency signals from exceeding a designated output level, which is essential for Dolby Digital and dts(-ES) sources that produce low- frequency signals peaks at much higher output levels than 2-channel sources. In home theaters, the subwoofers and their associated amplifiers might not be able to reproduce these signals without overloading.
