3.6 – Zone Outputs
Each of the local outputs has their own output controls. Figure 11 shows the controls for the local analog audio
outputs.
Figure 11 - Zone Output Controls
3.6.1 – Parametric EQ
Each output has two fully adjustable parametric EQs. Each EQ has a gain, a Q and a frequency control.
3.6.2 – Limiter
A limiter is provided on each output with individual controls for threshold, attack and release. The limiter can also be
bypassed entirely which is the default setting. To activate the limiter, click the bypass LED to turn the bypass off.
3.6.3 – Output Gain
This gain control is used to adjust the final level for a particular output. Up to +12dB gain can be added and up to -
100dB attenuation. A level of -100dB is considered muted.
3.6.4 – Pre-ducker/Output Volume
The pre-ducker volume and output volume show the current volume level of that particular logic input control. The
volumes themselves range fro 0dB down to -40dB. This cannot be changed by the interface and is purely for reference.
3.6.5 – Ducker
The Ducker allows audio from other sources to be used to override the default output zone audio. The Ducker has two
stages called primary and secondary and each can be fed with a different source. The output of the ducker is
determined by the sources selected for each stage and their audio levels. The options for configuration are shown in
the table below.
Source Setup Action
None Default audio will pass though regardless.
Primary source only
If the primary source level is above the threshold, the output will be the primary
source audio otherwise the default zone audio will play.
Primary and Secondary source
If the primary source is above the threshold, the output will be the primary source
audio. If the secondary source level is above the threshold and the primary is below
the threshold, the output will be the secondary source audio. If both sources are
below the threshold, the default zone audio will pass through.
3.6.6 – Source Select - Secondary Audio
This control is used in conjunction with the source select logic input and defines the secondary audio stream that will
be used when the appropriate source select input is active. The value has no affect if a source select logic input isn’t
configured for that zone.
