Bass Management - Emotiva XMC-1 User Manual

Operating the XMC-1
Note: When the Video on standby feature is enabled, pressing the standby button (from on)
places the XMC-1 in a special standby mode. The XMC-o/s remains loaded in this mode, and so
doesn't have to be re-loaded when you turn the XMC-1 back on. leaving the Video on standby
Mode enabled allows the XMC-1 to switch from standby Mode to on very quickly. for this
reason, you may prefer to have Video on standby Mode enabled even if you don't watch video
while the XMC-1 is in standby Mode.

Bass Management

The XMC-1 is a full 7.2 channel surround sound processor, which means that it supports two
independent stereo subwoofers.
If you have two subwoofers, and configure the XMC-1 for Stereo subs, then both subs will be
configured separately, and will operate in full stereo mode. Both subs will receive content from
the LFE (low frequency effects) channel and, in modes where bass management is active, the Left
Subwoofer will receive audio content at frequencies below the configured crossover points for
the Left Front, Left Surround, and Left Back Surround Speakers; the Right Subwoofer will receive
audio content at frequencies below the configured crossover point for the Right Front, Right
Surround, and Right Back Surround Speakers; both subwoofers will receive audio content below
the crossover frequency for the Center Channel.
If you have two subwoofers, and configure the XMC-1 for Dual Mono subs, then both subs will
be configured separately, but both will receive the same summed mono signal. Both will recieve
content from the LFE (low frequency effects) channel and, in modes where bass management is
active, will also receive audio content at frequencies below the configured crossover points for
your Front, Surround, Back Surround, and Center Speakers.
If you have one subwoofer, and configure the XMC-1 for a Mono sub, then that sub will receive
content from the LFE channel and, in modes where bass management is active, it will also receive
audio content at frequencies below the configured crossover points for all your other channels. In
this configuration, your one sub should be connected to the XMC-1's Left Subwoofer output.
Note: Because some "localization" of subwoofer content may occur in some situations, stereo
subs should ideally be identical, and should be positioned symmetrically in the listening room.
If you have two very dissimilar subwoofers, or plan to place two or more subs in positions
that are NoT symmetrical - perhaps for purposes of evening out response variations caused
by major room modes, you may get better performance by configuring the XMC-1 to use Dual
Mono subs. Using asymmetrically placed stereo subwoofers, or dissimilar stereo subs, may
result in imperfect imaging and a sound stage that is less than optimal. This will depend on the
specifics of your subwoofers, your listening room, and your configuration.
