Hello addressee_placeholder
Last month we were at NAB introducing HDMI; today we're reporting live from AES Amsterdam and we're introducing two new analyzers: APx520 and APx525.
It's been a great show. Strong interest in the new instruments (and HDMI), nice coverage in the show daily, and lots of enjoyable conversation with old friends and new faces.
Of course, our big news is APx520 and APx525. We're very confident that these new two-channel analyzers will meet a demand in the mid-range of the market by delivering the speed and ease-of-use of APx with higher performance and lower cost.
We look forward to your feedback as Partners get out into the field demonstrating how these analyzers will help you get your job done faster.
APx520/525 is a two-channel audio analyzer that combines the award-winning APx user interface with AP’s legendary commitment to performance.
APx520/525 is for both R&D engineers and production technicians who want fast and easy audio test, but who may not require the ultra-high performance of AP’s 2700 Series or the simultaneous multiple channel capability of APx585 and APx586.

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 with the same performance and analog connectors, but no digital I/O. Both use the same APx500 software as the other APx analyzers.
New breakthroughs allow APx520/525 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.
In addition to conventional balanced common mode rejection measurements, APx520/525 is also the only audio analyzer in the world to enable CMRR measurements in accordance with IEC60268 section 14.15.1.
All settings for a test are saved in a single project file that’s readable by any APx analyzer and small enough to email, making it easy to replicate test setups between R&D and production facilities anywhere in the world.
TYPICAL APPLICATIONS
APx520/525 is an excellent choice for most analog and digital audio applications (unless you need the ultra-high performance of the 2700 Series)
