broadcast.
2 x mono, balanced, line level (0dbU / 0.775Vrms), 15kΩ input impedance.

AMP LINK
The AMP LINK (RED vertical cat5 cable) is the secured bus connecting the Impact
Controller to up to 16 x DCA2.500 amplifiers. Based on RS485, this internal system
bus provides:
-
2 balanced audio channels across the entire AMP LINK chain, monitored;
-
Control and diagnostics data interface.
In order to work properly, the AMP LINK must be set up in the configuration settings
(“Amplifier” tab).
Amplifiers connected to the AMP-LINK are addressed and initiated by the Controller
at each system reboot.
NOTE: Reboot the system (Controller front panel RESET) after each modification
applied to any amplifier on the AMP-LINK, including:
-
replacing / adding / removing a DCA2.500 amplifier (along with new configuration settings);
-
changing DIP-switch settings on DCA2.500 back panel;
-
replacing the battery;
