APX-525 回收音頻分析儀 APX-525 AP APX-525 美國APX-525

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. 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).

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.

There is no need to compromise

The APx525 family offers unbeatable performance starting under $10K in the US.

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 the only audio analyzer in the world to enable CMRR measurements in accordance with IEC60268 section 14.15.1.

Sharing projects
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.
