CLIP indicators light up when the signal level feeding the loudspeakers is just below the
actual clipping. This CLIP system takes into account possible variations in the supply
voltage, always giving a real indication. CLIP indicators light up to the beat of low
frequencies when working at high power levels; it's normal as low frequencies are those
with higher energy content. You must take care that these indicators do not remain
continuously lit.
SP Signal Presence indicators indicate the presence of a valid signal at the amplifier inputs.
7. CLEANING
The front panel should not be cleaned with dissolvent or abrasive substances because silk-
printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral
liquid soap; dry it with a clean cloth. Be careful that water never gets into the amplifier
through the holes of the front panel.
