CONNECTION
Make the connections with the amplifier and all the audio system components switched off and disconnected
from the power supply.
Connect the USB storage device and/or CD to the corresponding inputs on the front panel. If you want,
connect the microphones in the connectors intended for them on the front panel.
Connect the audio source to the AUX/PHONO input, selecting the input type with the corresponding selector
on the back panel of the device.
Connect the speakers to the speaker output. Use any of the low impedance outputs (4, 8 or 16 Ω) or the 100
V high impedance line output depending on the type of speakers that you are going to connect. Do not use
both types of output at the same time.
If you use the low impedance output, you must connect the speakers in a series/parallel circuit so that the
speaker load impedance is the same as the amplifier output impedance and the power supplied by the
amplifier does not exceed what is withstood by the speakers.
If you use the high impedance 100 V line output, the speakers must all be connected in parallel and the sum
of the power of all the speakers must not exceed the power supplied by the amplifier.
In the case of connecting the amplifier to a 12 V DC battery, respect polarity.
Once the connections have been made according to your needs, connect the equipment to the mains and
switch them on. After use, do not forget to switch them off and disconnect them from the mains.
