Features
The AT 3130 can be used in sound systems at 70 or 100 V constant voltage to regulate the power of one or more speakers equipped with line transformer.
It can supply loads with maximum total power of 30W, and makes it possible to select the output power from 5 different values in order to create sound systems with different ambients acoustic levels.
