mute or solo. In the mute mode, individual
channels can be muted as required. In
the solo mode, a single channel can be
monitored while the others are automati-
cally muted. Depending on a configuration
setting, the mute/solo activity will impact
audio either pre (before) or post (after)
the downmix functions. In either solo mode
multiple channels can be simultaneously
selected for “soloing.” The flexibility of hav-
ing both mute and solo available allows an
operator to quickly select the most com-
fortable and productive operating mode.
A special solo mode is also provided,
called channel pop solo, which offers a
unique aid in monitoring audio material.
Channel pop solo allows the level of a sin-
gle channel to be raised while the level of
the other channels is reduced. This helps
to emphasize the content on one channel
without fully muting the others. Broadcast
applications can benefit from this solo
mode, allowing, for example, the center
channel to be highlighted while still main-
taining some level on the other channels.
The amount of level increase—the “pop”—
as well as the amount of attenuation can
be configured to meet the needs of specific
applications. Note that channel pop solo is
only available when the mute/solo function
is configured for post downmix.
Two functions allow the format of the
monitored sources to be checked for level
or phase inconsistencies. The surround to
stereo downmix function is used to create
a stereo signal from the selected surround
(5.1) source. The stereo to mono downmix
function allows audio on the left and right
channels to be added (summed) and moni-
tored on the center output channel. The
two downmix functions can be simultane-
ously enabled, allowing a surround source
to be checked for mono compatibility. A
small speaker simulator feature is associ-
ated with the stereo to mono downmix
function. It is included to assist an opera-
tor in determining compatibility with “real-
world” playback environments. It functions
by placing an audio bandpass filter into
the path of the mono signal, simulating the
