6.3 Indicators
eHSA amplifiers include a simple yet effective indication system.
PROT indicators show the absence of loudspeaker output signal. These indicators
may light up for following reasons:

During start-up, until the boot time time has passed. This time period is
needed for the internal operating voltages to settle.

A short circuit is detected at the loudspeaker terminals (PROTECT function).
If these indicators remain lit in red, there's a malfunction that should be investigated
to find the cause of this lighting.
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.
