This LED lights up if a signal is present at the power amplifier output The indicator goes off when the speaker line has shorted or a protective circuit has been activated thus indicating that there is no signal at the speaker output terminals 5 LIMIT This LED lights up if the limiter has been activated and the power amplifier is being operated at the clip level If the LED flashes briefly this is not a cause for concern If this LED is lit permanently the volume should be reduced to avoid overload damages to the connected loudspeaker systems 6 PROTECT When this LED lights up during operation one of the protection circuits against over temperature overload shorted outputs radio frequency interference or DC faults has been triggered The cause of the error e g a shorted loudspeaker line must be remedied In case of overheating wait a little until the amplifier switches back to operating mode itself 7 POWER Switch The unit is switched on via the power switch The loudspeaker outputs are switched on via delayed relays so that no startup transients are audible A current limiter prevents startup peaks on the mains line and prevents the mains fuse from blowing REAR PANEL CAUTION FOR CONTINUED PROTECTION e m f 73 AGAINST RISK OF FIRE REPLACE WITH u 5 p E B PARTS MAD E
