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 2 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..

Note : don't adjust the gain to high or the sound must be saturated
19. MIC 3 PHANTOM POWER BUTTON
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.. Sortie line out
Le signal sur cette sortie est le même que celui de la sortie HP. Vous pouvez donc vous en servir pour brancher un autre amplificateur.
20. LINE OUT
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.
21. AUX 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 ).
22. AUX 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 ).
23. MIC 3 INPUT(LINE LEVEL )
Connect on this input the receiver of a wireless microphone ( LINE level ). As the level of this input is LINE, 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 ).
24. MIC 2 INPUT(LINE LEVEL )
Connect on this input the receiver of a wireless microphone ( LINE level ). As the level of this input is LINE, 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 ).
25. MUTE CONTROL
This control is used to adjust the level of decrease for priority function. This function operates on all input ( except mic 1 ).
