8. CONNECTION OF TELEPHONE AUDIO SIGNAL
Connect telephone output terminal to screw terminal TEL INPUT(
fig.2
ref.10). Use the most suitable connection accordingly to the audio
telephone signal characteristics. ( make reference to the telephone manual
user).
Balanced connection
Unbalanced connection
In order to access to the speakers terminal screws i (
fig.2
ref. 10) remove
the protection cover :unscrew the fixing screws.
9. CONSTANT IMPEDANCE LINE
In order to have a constant impedance line (8/4
Ω
) connect the two
terminals respectively to COM e 8 o 4
Ω
(
fig.2
ref. 8).
•
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.
