If 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. If you assign a new ID, all elements with already
assigned IDs must be turned on and connected to the Pronet network.
n
If the elements is already on, pressing the button selects the DSP preset. The selected preset is indicated by the
corresponding LED.

[STANDARD]
This setting is suitable for all applications where the frequency range up to 90 Hz is to be transmitted and ampli‐
fied. The setting is suitable for most environments and for combinations with vertically flown Line Arrays.
n
[INFRA]
This setting can be used when a deeper ‘response’ in the bass range is required. This will slightly reduce the
sound pressure of the system. Note that the settings
[STANDARD]
and
[INFRA]
should not be used by two adja‐
cent devices at a time.
n
[CARDIOID]
This setting is useful for a device that is set-up between two other subwoofers of the same type and emitting
horizontally in the opposite direction. The bass level is reduced towards the stage.
