ALC-1809

At the nucleus of every Theory surround sound system is the ALC-1809, 9-channel Amplified Loudspeaker Controller.

With 1800W and 96kHz/32-bit digital signal processing, the ALC-1809 is the AV version of an integrator’s swiss army knife, combining the functionality of five products in one: a multi-channel DSP processor, high power multichannel home theater and distributed audio amplifier, multichannel mixing amplifier, multichannel bass manager, and high-resolution loudspeaker processor, all in a stylish, 1U package.

Automator

Theory's Automator™ software runs on the ALC-1809 and the intuitive interface walks installers through a simple five-step system configuration. Installers can deploy and configure spectacular sounding surround sound systems with up to 18 loudspeakers with minimal effort.

With a single ALC, a 7.2 or 5.2.2 system can be configured from start to finish in just 15 minutes. Or, use two ALC-1809s to configure systems up to 9.4.4 or 7.4.6 just as easily. Automator™ also provides printable wiring graphics and tabular wiring diagrams to simplify system hook-up.
