CLIP/PROT indicators functioning as CLIP indicator.
These illuminate when the signal given to the loudspeakers is 1.5dB before the real clip. This CLIP system
takes into account the possible variations in the mains voltage always giving a real indication even if the electric
mains varies. It is normal that working at high power levels, the CLIP indicators illuminate at the rhythm of the low
frequencies which are the ones that passes major energetic contents. Make sure these indicators are not
permanently illuminated.
THERMAL protection indicator (3)
Alerts of the tunnel cooling temperature when it has risen above 90 centigrade degrees. The amplifier will
then start up automatically when the temperature descends to 75 centigrade degrees.
The DPA power amplifiers feature separate thermal protection systems per channel. They operate
independently, meaning that if one channel triggers its protection system, the other one can perfectly continue its
normal operation.
SP Signal Presence indicator (4)
It points to the existence of signal at the amplifier input. These indicators light up when the input signal
surpasses -40dB.
5. 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.
