7. SYSTEM CONFIGURATION EXAMPLE
7.1. Control by the External Control Device
The following 2 methods are used to control the DP-SP3 from the external control device.
Functions to be controlled differ depending on each method.
7.1.1. Method of direct control
This example shows a method to control the DP-SP3 by directly connecting the external device’s contact
outputs to the DP-SP3 unit’s contact inputs.
Controllable functions: Preset memory recall, Volume control, and Mute ON/OFF

[Controlling multiple DP-SP3 units (up to 4 units)]
In this event, control becomes active only to the DP-SP3 to which the contact output is connected. But the
Preset memory recall function is interlocked among the DP-SP3 units.
7.1.2. Method of control via LAN
This example shows a method to control the DP-SP3 by the external control devices via LAN.
External control DP-SP3: Preset memory recall, Volume control, Matrix settings, and Mute ON/OFF
DP-SP3 External control: Preset memory number, Volume control, Matrix, and Channel mute notification
[Controlling a single DP-SP3]
[Controlling multiple DP-SP3 units (up to 4 units)]
In this event, control becomes active only to the control target DP-SP3. But the Preset memory recall function
is interlocked among the DP-SP3 units.
Other controllable functions are the same as described above.
