14.2 FULLY CUSTOMIZABLE BASS MANAGEMENT
The SDP-75 allows you to specify how the lower frequencies of each channel will be reproduced by one or more
subwoofers. For every speaker you can:
• Specify a High Pass Frequency;
• Activate one or more subwoofers that will reproduce the lower frequencies from that channel;
• Setup the gain for each subwoofer;
• Invert the polarity for each subwoofer.
This is different from the majority of the currently available AV surround preamplifiers which offer relatively simple bass
management features. They usually allow you to choose from only two types of speakers: “large” or “small”, and have
predefined parameters for the bass management filters.
