The Bass management is divided into 3 different sections represented as 3 tabs which will be detailed in the follow-
ing chapter:
• Quick Setup : The Quick Setup is the default section of the Bass Management. It allows a global configuration
by applying values on several speakers and subwoofers simultaneously (It is not enable if Bass-Management is
Off);
• Individual Setup : The Individual Setup provides the ability to adjust the settings on each speaker and sub indi-
vidually (It is not enabled if Bass-Management is Off);
• LFE & Misc : This allows adjustment of the LFE gain, polarity, Low-pass filter type, Low-pass frequency, slope,
as well as enabling the st10dB LFE input and stacked sub correction.
The Bass Management page is also accessible through the Top Menu of the Altitude

User Interface
The Altitude

allows you to specify how the lower frequencies of each channel will be reproduced by one or more
subwoofers or speakers. For each speaker you can:
• Specify High Pass and Low Pass filters for respectively the speaker and the bass-managed signal redirected to
the subwoffer(s) or speaker(s) (including frequency, filter type and slope);
• Activate one or more subwoofers or speakers that will reproduce de lower frequencies from that channel;
• Setup the gain and polarity for each bass-managed signal redirected to one or more subwoofer(s) or speaker(s);
• Setup the gain for each subwoofer;
• Invert the polarity for each subwoofer;
• Route the LFE channel to one or more suboofer(s) or speaker(s).
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.

• Off: No bass management (default)
• On: Standard bass management mode + intermediate bass-management mode
• On + LFE to LR (legacy): Distributes the LFE signal only to the Left and Right speakers. Can be used when there
