5. Clip/Limit Indicator
This indicator signals when the amplifier output is clipping or limiting. There are two different indication
states depending on whether the rear panel clip limiter is engaged (see Sections 4.2, 8.1):
•
If the clip limiter is engaged, the Clip/Limit Indicator has a short time constant and illuminates
briefly.
•
If the clip limiter is not engaged, the Clip/Limit Indicator has an increased time constant and
illuminates for a longer period.
6. Fan Grill Filters
Two grilles with foam filters are located on the front panel in order to prevent dust from entering the
amplifier. The grilles are removed by simply pulling them off, allowing for convenient cleaning of the
filters. Foam filters should be used at all times.
7. Power Switch
Turns the mains power on or off.
8. AC Indicator
Indicates if AC voltage is present. Note: this indicator is located electrically in front of the power switch.
9. AFS Indicator
Indicates if the AFS™ (Automatic Fuse Saver) current limiter is activated.
