2. Output connnections
Attention
To prevent the risk of electric shock, never touch amplifier outputs when the amplifier is turned on.
• Speakers connections.
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 (4Ω) 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 (4Ω), 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).
