- Page 17 Connections and operating elements 8 Preset button This button has two functions: If it's kept pressed while turning the device on, the ID assignment is made. The internal digital signal processor (DSP) assigns a new ID to the device for the remote control within the Pronet network. Each element must have a unique ID so that it can be represented in the Pronet network.
- Page 18 Connections and operating elements This LED lights up when the user setting is loaded. This setting corresponds to the user preset no. 1 of the DSP. In delivered condition, the user setting is identical to the setting STANDARD. If you want to change it, you must connect the element to a PC, edit the parameters using the Pronet software, and save the setting to user memory preset no.

Page 19: Starting Up
Starting up Starting up Switching on After you have made all the required connections, turn on the audio system. It is recommended to provide one switch for turning on the entire audio system and to always leave the powerCon plugs connected to the sockets of the individual elements. With this simple trick you can extend the life of the powerCON connectors. - Page 20 Starting up Application example for stacked The units can be combined vertically or horizontally to subwoofer stacks. Of each three subwoofers devices, the middle one should aim to the stage working with the DSP preset CARDIOID . The other two devices point toward the audience and work with the DSP preset STANDARD. By this configuration, the bass level for the artists on stage is reduced, but maximized for the audience.
