5.6 Output connections
The output section on the rear panel features Euroblock connectors.
Connection to high impedance lines: The loudspeakers line has to be connected to the
amplifier’s 0V and 70V terminals (70V line) or 0V and 100V terminals (100V line).
Connection on low impedance lines: The connection of the speaker line to the amplifier
should be made using the Lo-Z ("+" and "-") terminals.
Each output channel is independent, so you can use your high or low impedance
connection regardless of how the other outputs are connected.
If you want to combine, in the same channel, high and low impedance, using the 2
connectors of the same channel, you have to consider the load you are connecting to the
terminals, never exceeding the 60W that the amplifier can deliver. Thus, if a load of 4
Ω is
connected to the low impedance connectors, it will not be possible to connect any
additional load to the 70/100V terminals (the amplifier will be protected), as the maximum
power transfer occurs to 4
Ω and the amplifier delivers the available 60W to it. However, if
a load of 8 Ω is connected to the low impedance connectors, a line of up to 30W can be
connected to the 70/100V terminals, as at 8 Ω half of the available power is delivered. The
rest of the available power can be delivered in lines connected to the same channel, never
between different channels.
Note:
the ground of the output connections are independent, never connect the "-" terminal
of the Lo-Z output together with the 0V terminal of the 70 / 100V line output.
The connection cable that joins the amplifiers outputs and the loudspeakers must be of
good quality, sufficient section and as short as possible. This is most important when the
distances to cover are long ones.
