SETTING BASS PEAK LIMITERS
The BASS PEAK LIMITERS option displays the BASS PEAK LIMITERS menu to set amplitude limits on low frequency signals sent to the Main Zone
audio output Subwoofer L/R and LFE connectors. This menu also sets amplitude limits on low frequency signals redirected to other Main Zone
audio output connectors. The MC-12HD is equipped with an internal limiter to prevent low frequency signals from exceeding a designated
output level. This is essential for Dolby Digital and DTS(-ES) sources that produce low frequency signal peaks at much higher output levels than
2-channel sources. In home theaters, there is a danger of the subwoofers and their associated amplifiers overloading when attempting to
reproduce low frequency signals.
Note:
You should configure BASS PEAK LIMITERS menu parameter settings
whether output levels are automatically or manually calibrated.
