PROTECTIVE CIRCUITS Your new Warwick LWA 1000 amplifier is equipped with a multitude of protective circuits to prevent it from malfunction under inappropriate operating conditions. Over current protection: All amplifier channels are over current protected on outputs. Current clipping is engaged when the amplifier channels exceed its specified peak current output. This can be seen as the output voltage of the amplifier being clipped.

TROUBLESHOOTING We apologize if your new amplifier doesn’t work as intended. We recommend this simple DIY troubleshooting because often the solution to the problem is most likely simpler than it seems. • Amp does not power up. - Check whether the correct fuse is inserted in the fuse compartment and that it is intact. • There is no sound from the amp and LEDs don’t light up - Check your AC mains outlet. - Check power cord and power switch position.
