Figure 74. Digital Audio Output Panel
The digital output section displays the detected audio format sent to the HDMI or twisted
pair output (see
Audio format on page 103).
NOTE:
If the detected format is
Multi-Ch
audio, the
Left
and
Right
faders and
meters are not applicable.
Limiters
The output limiters restrict the input signal level by compressing its dynamic range when
exceeding a specified threshold. They are most commonly used to prevent clipping,
protecting a system against component or speaker damage. They are enabled by default,
which is the recommended setting for most configurations.
When a limiter is enabled, the following are set:
• Threshold — Activates or deactivates the limiter (subject to attack or release time) after
the signal level exceeds or drops below -0.1 dBFS.
• Attack time — Activates the limiter after the signal level reaches or exceeds the
threshold level for 2.0 ms.
• Release time — Restores the output signal level to normal (unprocessed) levels when
the signal level remains below the threshold level for 100 ms.
•
Ratio — Reduces the signal level at a 100:1 ratio when the limiter is activated.
• Soft knee — Smooths and softens the transition from unprocessed to processed
output levels.
To enable or disable a limiter on an output:
1. Click the
Output
tab (see figure 65 ,
4
, on page 102).
2. For the desired output, click the
Limiter
button (see figures 70 through 74,
1
, above
and on the previous page) in the appropriate output section.
Mix options
Output mix options determine what audio is output. Options vary depending on device
model and output connector.
For amplified outputs:
1. Click the
Output
tab (see figure 65 ,
4
).
2. If desired, deselect the
Mic/Line
checkbox in the
Mix
Options panel (see figures 71
and 72 ,
2
, on the previous page) to not include the mic/line inputs in the amplified
output (this is selected by default).
