UNBALANCED
23. LINE WITH CONSTANT IMPEDANCE
To have a line with constant impedante (8Ω) connect 2 terminales
respectively to terminal COM and 8Ω (fig.2 ref. 10).
• To ensure the maximum output, the total impedance of the speakers
connected to the line must be equal the amplifier output impedance.
• The total power of the speakers cannot be below the output amplifier
power .
• Advice: reduce to the minimum and as far as possible the connections
length . The cable section should be defined and increased
considering these distances.
24. LINE WITH CONSTANT VOLTAGE
To have a line at constant voltage (50 / 70 / 100 V) connect 2 terminals
respectively to COM and to the tension value of your choice (fig.2 ref10).
• The speakers must be with transformer with a input voltage equal to
the one supplied by the amplifier .
• Total power of the amplifier should not exceed the output power
amplifier.
