ALC-1809 LOUDSPEAKER CONTROLLER
18
PROGRAMMING OVERVIEW
During the programming process, you will communicate with the DSP Engine inside the Theory ALC (using suppled
Theory SurroundWizard™ software) to install loudspeaker programs and auxiliary filters that will be used during
operation to process the audio for the connected loudspeakers within the system.
This process is accomplished with the ALC connected to a Microsoft Windows computer via the supplied mini USB
cable. On one end there will be a standard USB connector, to be plugged into the PC, and on the other end there
will be a mini USB connector, to be plugged into the Theory ALC.
LOUDSPEAKER CONTROLLER CONCEPTS TO KNOW
Your Theory Loudspeaker Controller is not just a multichannel amplifier, or even a multichannel amplifier with DSP.
The Loudspeaker Controller, as its name implies, provides all signal conditioning, power limiting, signal filtering,
signal mixing and routing required for your state-of-the-art Theory surround system to function optimally. As such,
never connect any Theory loudspeakers or subwoofers to third party amplifiers as poor performance and potentially
loudspeaker damage could result.
Even though the Theory SurroundWizard™ quick start interface was designed to be bulletproof and will largely
automate configuring your Theory surround system for you, there are certain concepts that will be good know as you
interact with and use your new sophisticated Loudspeaker Controller.
CONCEPT TO KNOW #1:
There are three places where the Theory ALC DSP program settings can exist: within ALC memory, within the
ALC DSP chip itself, and within an (optional) backup file on your hard disk.
CONCEPT TO KNOW #2:
Theory SurroundWizard™ software allows control of settings currently running the DSP chip and facilitates the
writing of the settings to the ALC memory and computer backup.
The software does not have any role during the running of the settings themselves inside the DSP nor does it
“store” any information within the software itself.
CONCEPT TO KNOW #3:
Each time a Theory ALC is powered-up, the DSP chip is initially “empty” - it does not remember any of the filter
settings or programs.
At power-up, an on-board micro processor loads the DSP parameter settings
from on-board ALC memory
.
