THEORY AMPLIFIED LOUDSPEAKER CONTROLLER

 

At the heart of every Theory system lies an Amplified Loudspeaker Controller (ALC). The ALC-1809 when used as the core of a 2.0, 2.1, 2.2, 3.1, 3.2, 3.3, 5.1, 5.2, 5.3, 7.1, 7.2 or 5.2.2 ATMOS surround sound system automatically configures itself for high-resolution Digital Signal Processing of the loudspeakers purchased, and sets audio levels, delays, bass management and signal routing within the system. All that is required from the installer is input of the listening distances and formatting of the decoding mode of surround sound processor.

The Theory Music and Surround Automator™ software handles the rest.

For advanced applications, the ALC-1809 is a virtual audio swiss-army knife: including 9-high power amplifier channels, 8 balanced analog audio inputs, 1 mic/line level input (software selectable), 96kHz/32-bit DSP processing including full signal routing, gain adjustment, 8x8 matrix bass-management, 8x8 matrix mixing, 160 parametric EQ’s (20 per channel), automatic audio signal ducking for intercom and paging (perfect to allow Amazon Alexa and other voice assistants to page any or all of the distributed audio system channels), Internal band-limited and full band pink noise and sine sources, and up 75msec of delay per channel.

All in a fan-less, stylish, 1U chassis.
