Loudspeaker Connection - RCF AM2160 Manuel De L'utilisateur

LOUDSPEAKER CONNECTION

Use 1 output only, DO NOT MIX 100 / 70 V and 4 Ω CONNECTIONS!
70 / 100 V CONSTANT VOLTAGE OUTPUTS
•
Each loudspeaker shall have a
line transformer with the input
voltage equal to the line voltage
(70 / 100 V).
•
The loudspeaker total power
shall not be higher than the
amplifier maximum power.
LOW IMPEDANCE OUTPUT (4 Ω)
•
The loudspeaker total impedance shall not be lower than
4 Ω. Note: a total impedance equal to 4 Ω allows the
amplifier maximum power delivery. A higher impedance
leads to a reduction of the power delivered by the amplifier
(e.g. 8 Ω: approx. ½ power, 16 Ω: approx. ¼ power). An
impedance lower than 4 Ω overloads the amplifier.
•
Loudspeaker models shall be chosen by considering the
max. power (AM 2160: 160 W on a 4 Ω load; AM 2320:
320 W on a 4 Ω load) that the amplifier can deliver.
•
Loudspeaker line should be as short as possible; long
cables may need large wire cross-sections.
•
Do not use, at the same time, both the low impedance
output (4 Ω) and the constant voltage output (70V or
100V), as this overloads the amplifier.
