Using the MBOX as a Music
Pass-Through Device
The MBOX may be configured as a
Music Pass-through device or Message
Repeater. Music Pass-through will
enable external music sources to pass
through the MBOX, and at a specified
time, duck the external music to play an
advertisement from the MBOX. There
are two options for music pass-through:
Using an external music source
This option will enable an external music
source to play through the MBOX and,
at a specified time, fade the music down
to a set volume (ducker depth) and play
the advertisement or message.
Using the MBOX as a music source
This option will enable the MBOX to
feed its own music output back into the
MBOX, fade the music at a specified
time to a set volume (ducker depth) and
play the advertisement or message.
Using an External Music Source
Any source can be used for the External
Music Source of a Pass-Through setup.
For example, you could use a looping
CD, satellite stream, or other audio
source.
Connect an RCA cable from the external
music source to the orange Audio
Input
on the MBOX
(See “Figure
2: Back Panel Audio Connections”
on page 12).
Run the green Zone 1 Output
to the
on-premises amplifier
.
When an advertisement plays, the
external music source will fade down to
the ducker depth. After the
advertisement has finished, the MBOX
will fade the external music source back
up to its normal volume.
Using the MBOX as a Music
Source
The MBOX can feed its own music
source from the green Zone 1 Output
into the orange Audio Input
, and
at any specified time the advertisement
or message will play on the pink Zone 2
Output
, fading the music to the
ducker depth.
Plug one end of an RCA cable into
green Zone 1 Output
, and the
other end into the orange Audio
Input
.
(See “Figure 2: Back Panel
Audio Connections
”
on page 12).
Plug another RCA cable into pink Zone
2 Output
and connect it to the on
premises amplifier.
The music from Zone 1 will play through
Zone 2, and at a given time, Zone 2 will
fade to the ducker depth. After the
advertisement is finished, the MBOX will
fade the music back to its normal
volume.
Adjusting Volumes for Music
Pass-Through
In order for Music Pass-Through to
function correctly, adjustments must be
made to the Ducker Depth, Fade, and
Input Volumes.
A Ducker Depth of 0 will result in a
music level of 0 when an advertisement
plays. Should you wish to have light
music in the background while an
advertisement plays, the Ducker Depth
should be set to any value other than 0.
A Fade time of 0 will result in a 0 second
fade at the end of the song and the
beginning of an advertisement. Mood
Media recommends a fade of 100 for a
1 second fade between the song and
advertisement.
Input Volume controls the volume of
music input from Zone 1. Mood Media
recommends a default value of 70.
