Output 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.

6.4

Clipping 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.

6.5

Protect 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:

FTX SERIES III

Stereo MOSFET Power Amplifier

FTX-2001

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.
