3. BASS TONE CONTROL
This control is used to adjust bass tone of the main signal
4. TREBLE TONE CONTROL
This control is used to adjust treble tone of the main signal
5. AUX LEVEL CONTROL
This control is used to adjust the level of the AUX input
Attention : 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 )
6. TEL LEVEL CONTROL
This control is used to adjust the level of the phone connected on the TEL input
7. MIC 1 LEVEL CONTROL
This control is used to adjust the level of the MIC inputs.
Note : The MIC 1input have a priority. That's mean when somebody talks on the microphone plugged on the mic 1 input, the level of the rest
of inputs ( except TEL input ) automatically decrease ( the level of decrease depends to mute level setup ). When the user stop to talk on
the mic 1 ( more than 3 seconds ), the level of inputs recover their normal level.
8. MASTER LEVEL CONTROL
This control adjust the level of the main signal ( MIC 1 and 2, AUX et TEL signals mixed )
9. MIC 1 INPUT
Connect on this input an microphone or the output of the wireless receiver ( Note : Micro level ).
This input have a priority. That's mean when somebody talks on the microphone plugged on the mic 1 input, the level of the rest of inputs (
Except TEL input ) automatically decrease ( the level of decrease depends to mute level setup ). When the user stop to talk on the mic 1 (
more than 3 seconds ), the level of inputs recover their normal level
Connector : Jack 6.35mm
10. VUMETER
These LED display shows the level of what ever is present on general output. If the led 2 to 8 light, the operating and level are OK. If the led
10 lights, that means the level is too high and the output is in distortion. So you must to decrease level of all input levels.
11. 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
12. MUTE CONTROL
This control is used to adjust the level of decrease for priority function. This function operates on all input ( except mic 1 and TEL input ).
On the min control, the function is disable.
Inputs recover their normal level if the user stops to talk on the mic 1 input more than 3s.
13. MIC 1 INPUT WITH PHANTO MPOWER
Connect on this input an microphone or the output of the wireless receiver ( Note : Micro level )
Phantom power, in the context of professional audio equipment, is a method for transmitting DC electric power through microphone cables
to operate microphones that contain active electronic circuitry.It is best known as a convenient power source for condenser microphones,
though many active direct boxes also use it. If the mic connected on the mic 3 input is a condenser microphone, please push this button to
activate phantom power
Note: If the microphone connected on the mic input is a dynamic mic, disable phantom power or you will destruct the mic.
Connector : combo ( XLR + Jack 6.35mm )
14. ENTRÉE MICRO 2
Connect on this input an microphone or the output of the wireless receiver ( Note : Micro level )
Connector Jack 6.35mm
15. AUX 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 OUTPUT
The signal of this output is the same of the main signal so you you can use this output to connect a secondary power amplifier
17. TEL INPUT
Use to connect a phone. You can listen on speaker the person who talk in the phone
This input have priority on all the rest of input.
18. SPEAKER OUTPUT
These output are used to connect low impedance speaker, 70V speaker or 100V speaker
19. POWER SUPPLY SOCKET + FUSE
Plug the AC power cord on this socket. Before plugging this cord in, be sure the voltage of AC outlet is correct. ( 220V )
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.
