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 SD memory card in the corresponding inputs on the front panel.
- If you wish, connect the microphones to the connectors for them on the back panel.
- Firstly, connect the audio sources to the inputs. Connect the loudspeakers to the loudspeaker output. Use
the low impedance 4 Ω output or the high impedance 100, 70 or 25 V line output, depending on the type
of loudspeakers that you are going to connect. Do not use the two 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, 70 or 25 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.
- 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.
