The ideal balance of analog performance and breadth of digital I/O.
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 APx555 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.
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: 1.248 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.
The APx52x Series offers unbeatable performance and value.
Wide range and low noise
New breakthroughs allow APx to generate signals all the way down to 0.1 Hz. Maximum input voltage is rated at 300 Vrms (160 Vrms for unbalanced) and typical THD+N is −108 dB (at 1 kHz, 2.5 V). No other analyzer in the mid-range class offers this level of performance.
Made to measure for power amp designers
Measure continuous maximum output and peak maximum output automatically, DIM measurements, view power spectrum graphs with a regulated frequency sweep and take other measurements as specified by the CEA-2006 and CEA-490A standards. In addition to conventional balanced common mode rejection measurements, APx525 is also capable of performing CMRR measurements in accordance with IEC60268 section 14.15.1.
All settings for a test are saved in a single project file that’s small enough to email, making it easy to replicate test setups between R&D and production facilities anywhere in the world. Project files are compatible with all APx instruments and each project is self-contained, so there’s never any worry about dependencies or broken links.
For customers, contract manufacturers or management, APx automatically generates rich graphic reports, with highlighted pass / fail limits and options to export as PDF, HTML, Excel or text.
“[With the APx525] Audio Precision has produced an instrument that will be hard to beat for the price.”
-- Graham Langley | Audio Media
The APx52x Series is an excellent choice for most analog and digital audio applications (unless you need the ultra-high performance of the APx555).
