16.- DC POWER INPUT:
supply, batteries, emergency power supply systems, etc. Make the connection with 2.5 mm² section
cable to the – negative and the + positive terminals.
NOTE: when the amplifier is used with 24 V DC, the power is reduced by approximately 20%.
CONNECTION
Make the connections with the amplifier and all the components of the audio system switched off and
disconnected from the power supply.
Firstly, connect the audio sources to the inputs. Connect the loudspeakers to the loudspeaker outputs.
Use the 4 Ω low impedance output or the 100, 70 or 25 V high impedance lines, depending on the type of
loudspeakers you are going to connect. Do not use both types of output at the same time.
If using the low impedance output, the speakers must be connected in a series/parallel circuit so that load
impedance of the loudspeakers is the same as the amplifier output impedance and that the power supplied
by the amplifier does not exceed that withstood by the loudspeakers.
If using a 100, 70, or 25 V high impedance line output, all the loudspeakers must 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 are made according to your needs, connect the system to the mains and turn it on.
After use, do not forget to switch it off and disconnect it from the mains.
