POWER ON INDICATOR - This LED light up when the mains switch is pressed .If it does not light
up ,the unit is not connected to the mains or the mains fuse has blown .
2
-15dB - This LED light up when the output reach -15dB .
3
Protect
LED
- 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. shorted loudspeaker line must be remedied .In case of
overheating ,wait a little until the amplifier switches back to operating mode itself .

limit indicator This indicator signals if the amplifier output is clipping or limiting. It has two
-
different indication states:
a:If the clip limiter is engaged, it has a short time constant, and it illuminates briefly.
b:If the clip limiter is not engaged, it has an increased time constant, and it illuminates for a
longer period.
5
Level control - Calibrated detente potentiometers to alter the total gain of the power amplifier.
In order to avoid distortions in mixing consoles upstream , these controls should normally be
positioned between 0dB and-6dB . The calibrated markings show the additional attenuation
directly.
6
Fan outlet gills - The amplifier uses forced air cooling. The cooling fan from the back of the intake
air, and then exclude from the back. Never obstruct the intake and exhaust ports.
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 .
