V. Accessing the DPA via the Internet Outside the Local Network
Follow these instruction in order to access a particular DPA amplifier from outside of the Network the DPA is connected to. Example:
An amplifier is in a school in Los Angeles and the volume in the classroom is not loud enough. The installer has the maximum level
set via the limiter. Instead of the installer having to drive to the school which is 3 hours away, he can access the amplifier from his
desk or phone. During the installation of the amp, the DPA was configured with a static IP address and a specific port assigned by the
school’s IT manager. This enables the installer access only to the specific DPA amplifier that needs the level adjusted. Below is a safe
convenient way to allow limited access to a specific product via a protected network. Setting up an external IP address eliminates the
requirement to VPN into a network to gain access to the LAN. This allows the person needing to maintain the device a single point of
entry and keeps the LAN secure.
1. Plug DPA amp into local network, determine the IP address assigned to the amp, and change it to a static IP address.
2. Create a NAT (Network Address Translation) on the WAN router or firewall using port 80. An external static IP address will be
needed for this process to work.
3. Once the external IP address is translated to the internal IP address, go to another Internet connection outside the Local Network
where the DPA amp is present and try connecting to the external IP address. Verify correct NAT has been established.
This link is an example of a DPA-102PM amplifier connected to a Network that allows access from the Internet. Type this link into a

tab and enter the USER NAME (admin) and PASSWORD (admin) to gain full access of the amplifier.
Amplifier Configuration & DSP Settings
1. When the DPA GUI is accessed for the first time, the DPA Amplifier is configured as a 2-channel amplifier with the front panel
level controls active and the USER level control on the GUI page deactivated.
Note: The DPA amp Output Level can be controlled by either the front panel Level or by the GUI, but not both at the same
time. To use the GUI User Level Control, the amp needs to be configured for that operation.
2. If the DPA amp GUI is open and looks like Figure 5, the front panel level controls are active.
Notice the fader controls are invisible.
