Remote Volume Control Connections to Ampliers
The following examples show how to wire the resistance control terminals of the
MLA VC10 Plus to an Extron MPA or XPA Series amplifier, or some common third-party
amplifiers.
Other amplifiers not shown here require similar connections but you must read the
appropriate user guides to ensure the wiring is correct.
Extron MPA or XPA Series Amplier
1. Connect the reference voltage
wire (V) of the MLA VC10 Plus
to the reference terminal of the
amplifier (10V on the MPA; V on
the XPA).
2. Connect the ground wire (G) of
the MLA VC10 Plus to the ground
terminal on the amplifier (
on
the MPA; G on the XPA).
3. Connect the control signal wire
(C) of the MLA VC10 Plus to the
control signal terminal of the
amplifier (Vol/Mute on the MPA;
C on the XPA).
Third-party Amplier (Three-pin Connection)
This example shows the MLA VC10 Plus
connected to an Ashly NE Series amplifier.
1. Connect the reference voltage wire (V) from
the MLA VC10 Plus to the reference voltage
terminal (+5V) on the amplifier.
2. Connect the ground wire (G) from the
MLA VC10 Plus to the ground terminal (Gnd)
on the amplifier.
3. Connect the control signal wire (C) from the
MLA VC10 Plus to the control signal terminal
(Ch 1) on the amplifier.
Third-party Amplier (Two-pin Connection)
This example shows the MLA VC10 Plus connected to
a TOA 900 Series amplifier.
1. Connect the ground wire (G) from the
MLA VC10 Plus to the left Remt Vol terminal on
the amplifier.
2. Connect both the reference wire (V) and the
control signal wire (C) from the MLA VC10 Plus
to the right Remt Vol terminal on the amplifier.
