ALFA helps you maintain a target level.
It can be used at the input or output point to maintain a constant program level. It compensates for miscalibrated incoming signals or hot CDs, and allows you to deliver level-controlled signals to other parties who may be operating at different plant levels.
Signal processing takes place in the digital domain; no conversion artifacts are introduced. It’s a card-based system so it’s small and can be outfitted as you need it; the box can handle up to eight AES channels of control in a 1RU frame and 20 channels of control in a 2RU frame.
Control can be automatic, or adjusted via a control panel. Unlike a compressor/expander, ALFA responds slowly in order to minimize the potential to change the dynamics of the signal; instead it acts to adjust the long-term average level of the signal.
Retail price ranges from $2,000 for two AES channels to $8,600 for 20 AES channels; larger systems are priced individually.
