Diagnostic and Protection

The DB751 is equipped with a self-diagnostic and status/protection circuit. Upon power-

up, the unit's blue status LED will blink for approximately 45 seconds. During this time

several circuit parameters are verified, or allowed to become self calibrated.

1. The high B+ voltage to the preamp tubes is slowly ramped up, allowing the tube

heaters to warm up before full current is drawn by the valves.

2. DC offset at the amp's output is monitored. Only if none is present (normal condition),

will the unit proceed with the self-check protocol.

3. Temperature on the MOSFET heat sink is checked, and again only if normal

temperature is detected, will the status check continue.

4. If all the voltages, offsets, and temperature are in accordance with factory

specifications, then the amp's input, and output relays will be energized. This will then

cause the operate LED to illuminate and the status LED to stop blinking. The amp is now

ready for normal operation.

5. The circuit continues monitoring the above parameters to protect both the DB 751 and

the speakers connected to the amp in the event of unit or user error. This will be indicated

by the status LED's blinking.
