The ALC4 Amplifier Loudspeaker Controller is a combination of a loudspeaker controller and a high efficiency power amplifier. The ALC4 is designed to guarantee the best loudspeaker drive, with maximum sound- and operating reliability. The amplifier stage consists of a 2x 2 kW amplifier in Class-G design, supplied from a conventional power supply with a torodial transformer and a massive 400 Joule capacitor bank with a large dynamic reserve for sustained high power output even in two ohm loads. In order to maintain strict quality standards, all Alcons products are burned-in and thoroughly tested before shipping. The proven combination of advanced design, quality construction and active protection circuits is your guarantee of fail-safe reliability and many years of trouble-free operation, while enjoying the excellent specifications. You can depend on consistent, stable performance, even in the most demanding fixed or mobile sound reinforcement applications.
The ALC4 is equipped with separate power supplies for both channels.
Balanced XLR inputs make the amplifier less susceptible to noise and AC hum pickup, especially when using long cable runs.
The XLR link output connectors are internally hardwired to the input connectors and can be used to daisy chain the input signals to another amplifier.
Each channel of the ALC4 is equipped with two four pole Speakon® outputs for easy installation.
