Output Channel − Sources
A primary purpose of the MP-M is to route audio signals
from the inputs (Sources) to the outputs (Zones). The
Sources screen is where the available sources are
assigned to an output and given their roles.
The MP-M uses Priority Sources to designate which inputs
are able to override the signal from other inputs. Each
output zone includes two duckers that are triggered by the
Priority inputs. (A ducker is a dynamic processor that uses
one audio signal to reduce the level of another signal.)
Assignments to sources are made from MP Install and
cannot be changed from the MP Manage app or the
MFC controllers.
• A signal arriving at the Primary input will reduce the
level of the Secondary Source and the Selectable
Sources audio.
• A signal arriving at the Secondary input will reduce the
level of the Selectable Sources audio but will not affect
the Primary Source input.

switch – Selects either the Primary source selection and setup, or the Secondary source selection and setup.
4.
Source select
button – Touch the drop-down menu to display and select from a list of available sources for the priority input.
5.
Source Level
– Sets volume level for the Primary or Secondary signals relative to the other zone inputs.
6.
Override Zone Level
(Primary Source only) – When the switch is set to the Yes position, the Primary Source level will not be affected by the
output’s master level control. This allows, for example, a page message to be heard at a pre-set volume no matter what the zone’s level setting
may be.
7.
Threshold
– Sets the level that the priority source must reach to trigger ducking.
8.
Depth
– Sets the amount of attenuation applied to the Selectable Source when ducking is triggered.
9.
Hold
– Determines how long attenuation is applied after the Priority input signal drops below Threshold.
Selectable Sources
A single output (Zone) may have up to 8 Selectable Sources assigned to it.
10.
On
– Selects the associated source as the active source for the output.
11.
Selectable Source
buttons – Touch one of the selection buttons to display and select from a list of available sources. Available sources are:
• Any input channel
• The output from the internal mixer section of the MP-M.
• Any other output zone or “Zone-Follows-Zone”. This function is used, for example, if a single area of a facility has different kinds of
loudspeakers (full-range / subwoofer) that require differing processing but it’s desirable for the entire area to operate as a single zone.
It can also be used for room combining in facilities with movable air walls.
• Silence – Silence may be selected as a means of muting an output. If silence is selected, the Priority sources will still function normally.
• None – None is the default selection. If None is the source for any of the 8 available source selection ‘slots’, that slot will not appear on
MP Install or on the MFC controllers.
12.
Level
– Adjusts the level of each source relative to the other sources.
