Stereo Equalizer
The BETTERMAKER STEREO PASSIVE EQUALIZER (SPE) is for those seeking exceptional EQ quality with the convenience of fast and precise recall and automation. The BETTERMAKER STEREO PASSIVE EQUALIZER offers 100% of the signal path of legendary passive filters. All this with mastering-grade sound and patented recall with the speed of a native plugin.
The sound of the BETTERMAKER STEREO PASSIVE EQUALIZER is, of course, based on the quality of its analog filters, perfectly matched capacitors, and inductors. But all control and user interactions are performed in the digital domain. This allows for the incorporation of options and possibilities not found in any standard analog equalizer.
The digital section of the BETTERMAKER STEREO PASSIVE EQUALIZER is based on a high-speed 32-bit microcontroller, with dedicated firmware programmed into its memory (with the possibility of firmware updates via USB connection) that controls the analog filter parameters, user interface, preset management, audio metering, USB connectivity, and other functions.
