10. PROTECTION LED
When this indicator lights, that means the power amplifier is in the protection mode. Switch off the device and
find out the problem.
This power amplifier is protected against over heat, over load, short circuit, DC, softstart
11. VUMETER
These LED display shows the level of what ever is present on general output. If the led 2 to 10 light, the operating
and level are OK. If the peak led lights, that means the level is too high and the output is in distortion. So you
must to decrease level of all input levels.
12. POWER LED
This indicator lights when the power amplifier is switching on

13. SPEAKER OUTPUTS
These outputs are used to connect speakers ( Sono ( 4-16 Ohms ) or P.A. ( 70V or 100V ) )
14. MIC 2 INPUT
Connect on this input an microphone or the output of the wireless receiver ( Note : Micro level ).
15. LINE 1 INPUT
The level of this input is LINE so you can connect on this input only items with LINE level ( CD player, Tape player,
minidisc, mixer,... ). You cannot connect turntable ( phono level ) or microphone ( mic level ).
16. LINE 2 INPUT
The level of this input is LINE so you can connect on this input only items with LINE level ( CD player, Tape player,
minidisc, mixer,... ). You cannot connect turntable ( phono level ) or microphone ( mic level ).
17. AC CORD
Plug the AC power cord into any standard AC outlet. Before plugging this cord in, be sure the voltage of AC
outlet is correct. ( 220V )
18. FUSE
The fuse is used to protect your power amplifier from different kinds of ac problems. If the power amplifier is
“on” and nothing lights, please verify the fuse compartment. If fuse is broken, please read it and change with
a new one of same size and value.
CONNECTION TO A SOUND SYSTEM ( 4-16 OHMS OUTPUT ) (figure 1) :
On the 4-16 Ohms output, you can connect several speakers.
Note : The total impedance of the speakers must to be from 4 to 16 Ohms. ( Two speakers in parallel = impedance
divided by 2 ), Two speakers in series = impedance x2 )
Connect the 4-16 Ohms output of the power amp socket of the speaker
Connect the COM socket of the power amplifier on the – socket of the speaker
