Lexicon 070-14876 manual Dc Protection, Basic Operation, LX Power Amplifiers

LX Power Amplifiers

DC PROTECTION

Each channel includes DC protection to prevent DC and frequencies below 10Hz from reaching the speakers. If this protection activates, the output relay will open and the corresponding front panel channel status LED will no longer be lit. After approximately 4-seconds, DC protection will be automatically deactivated. The relay will close and the corresponding channel status LED will light blue. If DC or frequencies below 10Hz are still present, DC protection will be automatically reactivated. The amplifier will continue to engage this protection until the problem is no longer present.
