approximate response of the system. Maximum
level of the capture can be set by adjusting
Mic Ref Level. Graph vertical scale can be
changed from Logrithmic (default) to Linear.

See "Dirac Live" on page 23 for use of optional
Dirac Live Calibration Tool.
8. Volume Reference
It is good practice when calibrating systems
to always work at a reference level such as
85dB C-weighted. Before activating the noise
generator, make sure the master volume is at
a low level. Set and recall a reference master
volume value. Click SET once you have dialed
the value you'd like to store. Click RECALL to
quickly return to that value.
Individual Channel Adjustments
Once your theater is defined, each channel can
be individually fine tuned. The theater can also be
renamed, and a child theater can be created which
enables stereo left, right, or mono audio to be
routed to existing channel assignments.
9. Channel Status
Each channel is enabled by default. If for some
reason this channel needs to be disabled, click
the ON button. It will turn to OFF and audio will
no longer be routed to that channel. Note that
audio will not be re-routed to other channels.
Channel status is set per Theater / Zone and is
not stored as part of a profile.
10.
EQ
Each channel can have up to 10 channels of
parametric EQ configured. See "Channel EQ" on
page 20 for detailed EQ options. EQ settings
are stored as part of profiles.

Signal
Indicates which signal is routed to this output.
Should you desire to remap signal routing, you
can do so with Output Mapping. See "Output
Mapping" on page 19 for details.
12.
Channel Name
Customizable name to easily identify each
channel. By default, these are named for the
signal sent to each channel. You may decide
to change these to speaker model or another
unique identifier. Maximum allowable character
count is 25.
13.
Size / Filter
Identify each channel as either Large, Small,
or Large and Sub. When a channel is set to
Large, no bass is redirected from this channel
to the subwoofer. Use this setting when the
loudspeaker has sufficient bandwidth and
output capability to reproduce sufficient
bass. When a channel is set to Small, bass in
this channel is redirected to the subwoofers
according to the Frequency and Slope for that
channel. Large and Sub is a special case that
not only allows that channel to reproduce full
bandwidth audio, but also duplicates bass in
that channel to the subwoofer(s) according to
the Frequency and Slope for that channel.
Subwoofer channels have specific settings. By
definition, subwoofers have limited bandwidth
and some are more limited than others.
Low Pass LFE: When this is set to ON, the subwoofer
•
channel has a low pass filter applied according to
that channel's Frequency and Slope. This is designed
to limit the channel's ability to reproduce the upper
portion of the bass spectrum. This is usually done to
prevent the subwoofer from contributing midrange
distortion.
Subsonic SUB: When this is set to ON, a high pass
•
filter is applied to the channel which restricts the
subwoofer's ability to reproduce very deep bass
according to the frequency and slope defined for
that channel. Many subwoofers, especially smaller
models do not have the amplifier power or driver
