APL1012
After 15 years of offering detailed EQ for complete loudspeaker systems, it is time to go to the next level of accuracy and use detailed EQ on each of ways/bands to make an ideal crossover. Please meet APL1012 – 10 channel ultimate FIR filter based loudspeaker system processor.
High Resolution FIR based loudspeaker system processor.
It brings detailed EQ of loudspeakers, known from APL1, to new level of accuracy by allowing to use the power of FIR detailed EQ for each of system’s ways. Thanks to APL Workshop, APL TDA EQ, APL TDA and APL C5 programs in set with APL1012 to make tuning process predictable and straight forward. Analog Device, Xilinx, Cirrus Logic chips are on board.
