.
To access to speaker connection terminals remove the protection cover unscrewing the correspondent
screws (
fig.2 ref. 5, ref. 6
).
This amplifier may be used both with constant impedance speakers (4 Ω ) and with constant voltage speakers
(25V, 70, and 100V). Make proper connections applying following instructions.
Constant impedance line
To use this amplifier with a constant impedance line (4 Ω ), please connect the COM terminal to the negative
post of your speaker and connect the proper impedance terminal to the positive post.
−
To obtain the best performances, total speakers impedance connected to the line, should be equal to the
amplifier output impedance.
−
The speakers power sum should not be lower than amplifier output power.
−
We suggest you don’t use long cables. Anyhow, for longer distances application use a thicker cable.
Constant voltage line
If you’re using a constant voltage line, connect either the 70, or 100V to the “+” side of speaker system, and
connect COM to “-“ side of the speaker (
fig.2 rif.10
).
