PROTECTION
The
Initial Power Up - For approximately five seconds after initial
Thermal Protection - Abnormally high heat sink temperatures will engage the Protection circuitry for the overheating channel only. An output relay disconnects the speakers until normal temperature range is restored. During this time, the Protect LED will light.
To guard against this problem, make sure the
Short Circuit - If output is shorted due to faulty wiring, the thermal circuitry will automatically protect the amplifier. If this occurs, the load will be disconnected by the thermal protection circuitry (also, the output relay opens).
DC Voltage Protection - If an amplifier channel detects DC voltage at the speaker output, the output relay immediately opens to prevent speaker damage.
Subsonic Frequency Protection -
Current Limiting Protection - At the amplifier’s full power limit, (or clipping point) the limiter circuitry will be activated. This is indicated by illumination of the Clip LED. The channel gain is automatically reduced, protecting the speakers from damage. This circuitry may be activated by uncontrolled feedback, oscillations,or improper equipment gain settings. This circuitry is virtually transparent in operation, and full signal bandwidth is maintained.
Any time the Protection LED lights up (except for approximately 5 seconds during initial
