Audio Precision APx521

APx525 has two balanced and two unbalanced analog inputs and outputs plus 192K digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. APx520 is an analog-only version of the 525. APx521 and APx526 are the four channel versions of the 520 and 525 developed for the 4 channel head units typical of the automotive audio industry.

Developed for power amp designers, the AG52 analog generator option generates exceptionally clean square waves with a rise time better than 2 microseconds and has an improved THD+N of -110 dB (typical). The AG52 generates DIM 100, 30, and B square + sine waveforms and maximum output level is increased from 21.21Vrms to 26.66 Vrms (balanced).
