23. MAIN SIGNAL DEVIATION (LOOP SEND)

It allows to obtain a sample identical to the signal coming from the master stage and that is directed towards 
the internal amplifier. It can be sent first to signal equalization processes to return loopback for additional 
power amplifier power through the use of a ¼ "monaural type phone plug.

24. MAIN SIGNAL RETURN (LOOP RETURN)

It allows to interrupt the passage of the main signal just between the master stage and the power amplifier to 
replace it with that obtained from any external processing such as an equalization. It can also be used to 
inject a completely different signal from the master stage (such as that of a monitors system) to the power 
amplifier included in the mixer while the main signal is drawn from the loop output send. The master-amplifier 
circuit is switched off automatically when a ¼ "monaural type phone plug is inserted.

25. SPEAKER OUTPUTS (OUTPUT)

For connection, a ¼ "monaural phone plug is used. It is advisable to use the correct caliber on the connecting 

 

cable to your speakers (do not use instrument cable). The internal connection of the output connectors is in 
parallel and the combined minimum impedance in the two output connectors must not be less than 2Ω.

26. OUTPUT FUSE (OUTPUT FUSE)

It has an electronic overload protection system in the output stage of the power amplifier. The system will 
disconnect the speakers whenever there is an improper condition caused by a short circuit or an impedance 
of less than 2Ω in the power output. In addition, its console uses a fuse in series between the power output 
and its speaker system. If necessary replace with an equal one.

27. AC POWER SWITCH (POWER)

Allows you to control the on / off status of the complete unit which will be shown by the ON indicator located 
on the front of the console. When the console is turned on, the transient protection system is automatically 
activated at the output, momentarily disconnecting the speakers to avoid any damage and then resetting 
seconds. Also the system will be activated just after the switch is brought to the off position thus avoiding the 
noises produced by the discharge of the source on the horns.

28. INPUT FUSE (A.C. FUSE)

For greater protection in the power supply the console uses an American fuse of slow fusion. If necessary 
replace it with another of the same type.

29. AC POWER INPUT

IEC AC Power inlet connector, plug this cable in to a standard 220V wall outlet. Be sure that supplied voltage 
matches that of the required voltage of this unit. Never plug this unit in to a wall outlet that does not match the 
required voltage, serious damage may occur to the unit.
