6.3Output Meters

Output meters display peak output voltage in dB, referenced to full output. For example, if full output in a given configuration was 400 watts, then “0” would mean the amp is delivering the full 400 watts to the load, “-6” would mean the output voltage is 6dB lower, or 100W.

6.4Clipping Indicator

Clipping occurs when the signal peak levels ex- tend beyond the available power supply rails, essentially “cutting off” the crest portion of the waveform. This pro- duces signal distortion and can potentially damage driv- ers, as the signal begins to look like a square wave. The red CLIP LED illuminates at the onset of clipping.

6.5Protect Indicator

Protect mode in ASHLY amplifiers is automati- cally activated during extreme fault conditions, as well as during power-up and power-down. When in protect mode, as indicated by the red LED, the speaker output terminals are internally disconnected. Conditions caus- ing the amplifier to switch into protect mode include the following:

Turn-on delay/Instant turn off

DC voltage at the output (signals below 8 hertz will be interpreted as DC voltage, and may trig- ger the protect circuit)

Output short circuit

Ultrasonic signals at high amplitude

After the abnormal condition ceases, the ampli- fier will automatically recover from protect mode.
