• AUX INPUT CONNECTIONS (CD player , AM/FM TUNER etc..)
I use shielded cable for long distance).
Revert to (fig.2 ref.5)
Set amongst the two AUX inputs available the one to be activated, PIN1 on position ON, AUX2 is activated
–PIN1 on position OFF AUX1 is activated.
Set the sensibility accordingly to input signal level through PIN4. PIN4 on position ON, input sensibility is set
at -10dbV- PIN4 on position OFF input sensibility is set at 0dbu
Setting PIN4 on position OFF Phantom power is disabled .
Advice : For speech purposes use, set PIN3 on position ON .
If the input level is too low, disabled the attenuation purposes setting PIN2 on position ON.
Balanced connections on EUROBLOC terminal
Unbalanced connections on EUROBLOC terminal
RCA connections
2. Output connnections
Attention
To prevent against electrical shock, Do never touch the amplifier outputs when powered .
To access to loudspeakers terminal connections (fig.2 ref.13) unscrew to remove the unit cover.
LINE AT CONSTANT IMPEDANCE
In order to have a line at constant impedance, connet respectively the two terminal to COM and the one with
the impedance line value selected (4, 8, 16Ω) (fig.2 ref.13).
• To grant maximum performance, the total loudspeakers impedance must be equal the output amplifier
impedance.
• Total loudspeakers power must be lower than the amplifier output power .
• Advice: the connections length should be reduced as far as possible .If necessary the cable section
should be increased in accordance with the connections distance.
LINE AT CONSTANT VOLTAGE
In order to have a line at constant voltage (70 / 100 V), connect respectively the two terminals to COM and the
terminal with the indication of the selected voltage (fig.2 ref.13).
• The loudspeakers must be transformer equipped and the transformer power input must be equal to the
power supplied by the amplifier.
• The total loudspeakers power must not exceed the maximum amplifier output power.
