PROTECTIONS
4PRO Series active speakers are equipped with a complete system of protection circuits. Two led on the amplifier
back panel indicate the working status of the amplifier: the green led indicate that the speaker is ON and the red
led is on when the protection circuit is active. The circuit is acting very gently on audio signal, controlling level and
maintaining distortion at acceptable level. If this led is ON for a long period is better to reduce immediately the
signal level from the mixer or from the speaker volume control.
