Audio Precision APx525 Family Audio amplifier and preamplifier

The APx525 is a two channel audio analyzer for R&D engineers and production technicians who want fast and easy audio test,but who may not need the ultra-high performance of AP’s 2700 Series nor require the multichannel capability of the APx585.","APx525 has two balanced and two unbalanced analog inputs and outputs plus 192K digital inputs and outputs via AES\/EBU,TOSLINK and SPDIF. APx526 is the four channel version of the APx525,developed for the 4 channel head units typical of the automotive audio industry.","Additionally,I\/O may be expanded with optional Digital Serial (APx525 and APx526),HDMI with ARC (APx525),and Bluetooth (APx525) modules.","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).","The BW52 ultra-high bandwidth option offers unprecedented FFT performance: One million points,DC to 1 MHz bandwidth and full 24-bit resolution. Ideal for Class D amplifier design and unmatched by any other test instrument.
