Volume control port — To provide volume control for some Extron audio amplifiers,
connect this port (see figure 18,
D
on page18) to the volume remote control port
on the amplifier as shown below. Configure the maximum and minimum voltage limits.
Set Soft Start mode off or on (default). Soft Start mode allows volume to gradually
increase from mute to the previous level after muting or power-on to prevent loud audio
bursts (see Soft Start mode on page34).

Control voltage output:
0 - 10 VDC
Reference
voltage: ≤10 VDC
NOTE:
Use shielded cable and
place the MLC Plus 84 as close
as possible to the amplier to
avoid picking up background
noise via the cable. Ideal cable
length is six feet or less.
NOTE: When audio
mute is active, the
MLC Plus 84 sets
control voltage
output to
0 VDC,
even if the voltage
range (minimum
and maximum
voltage limits) have
been set to levels
above zero, such
as 2 V to 8 V.
Volume Control
This port can be used to control the volume and mute or unmute the audio for some
Extron audio ampliers with remote volume capability.
• Connect to an Extron audio ampier to
permit volume control via the MLC
Plus 84,
including via
macros, or schedules.
• Do not exceed 10 VDC input voltage.
Settings to configure via software:
• Maximum and minimum voltage
limits
• Soft Start mode: off or on (default) − to allow
volume to gradually increase from mute to
the previous level after muting or power-on
to prevent loud audio bursts
