DC fault protection
If DC or excessive subsonic energy appears at a channel output, an instantaneous protection circuit
will inhibit the power supply for all channels. Power supply shutdown is used in lie of speaker relays,
thereby improving the damping factor and reliability of the DIGAM amplifiers.
Input/output protection
An ultrasonic network decouples RF from the outputs and keeps the amplifier stable with reactive
loads.
User maintenance
Cleaning:
Disconnect the amplifier from the AC main source first; use a soft cloth and mild non-
abrasive solution to clean the faceplate and chassis.
Dust removal:
Especially in a dusty environment, the heat sink may clog with dust after prolonged
use, which will interfere with cooling. You may use compressed air to remove the dust; severe cases,
though, should be referred to qualified service personnel for a thorough cleaning with the top cover
removed.
There are no user-serviceable parts in your DIGAM amplifier. Refer servicing to qualified technical
personnel.
In addition to having an in-house service department, Powersoft supports a network of authorized
service centers. If your DIGAM amplifier needs repair, contact your Powersoft dealer or distributor, or
contact the Powersoft Technical Service department, to obtain the location of the nearest authorized
service center.
