Volume control port — To provide volume control for some Extron half rack audio
amplifiers (such as the XPA and MPA models listed in figure 19), connect this port (see
figure 14 and figure 15 on page18 and page19) 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.

Reference voltage input (from amplier) – This allows the IPCP Pro to detect when the amp is present.
Control voltage (variable output to amp from IPCP Pro) – This signal controls the amp volume.
Control voltage output:

Volume Control
This port can be used to control the volume and mute or
unmute the audio for Extron half rack width audio ampliers.
• Connect to an Extron audio amplier to permit volume
control via touchpanel controls, macros, or schedules.
• Do not exceed 10 VDC input voltage.
Congure 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.

NOTE: Use shielded
cable and place the
control processor as
close as possible to
the amplier to avoid
picking up background
noise via the cable.
Ideal cable length is
six feet (1.8 m) or less.
NOTE: When audio mute is active,
the control processor sets output
voltage to 0 VDC, even if the
voltage range (minimum and
maximum voltage limits) has been
set to levels above zero, such as
2 V to 8 V.
