Created on 2008-05-17 16:27:00

AES, Amsterdam – May 17, 2008 –  Audio Precision, the recognized standard in audio test, today unveiled two-channel models of its award-winning APx500 Series audio analyzer.

The APx520 and APx525 are two-channel audio analyzers that combine an award-winning user interface with AP’s legendary commitment to performance. APx525 has two balanced and two unbalanced analog inputs and outputs plus 192K digital inputs and outputs. The APx520 has the same performance and analog connectors, but no digital I/O. 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).  APx520/525 is also the only audio analyzer in the world to enable common mode rejection ratio (CMRR) measurements in accordance with IEC60268 section 14.15.1.

Both instruments are for 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.

“Our customers expect AP to provide the right tools for the job,” said Bruce Hofer, co-founder and Chairman of Audio Precision. “The 520 and the 525 have better performance than any analyzer in the mid-range class and I’m happy to report that the lower channel count allows us to offer both instruments at a very competitive price.”

APx is high speed, high performance, and user friendly. Innovations include one-click measurements, the automated measurement sequencer and continuous sweep technology that can derive 14 measurements in as few as 7 seconds. No other analyzer is faster or easier to use.

Price and Availability

Pricing for the  APx520/525 starts at $9900 in the US. Price may vary in other countries. All AP Sales Partners are now accepting orders, and the first units will ship in mid-summer 2008. Please contact your local AP Sales Partner for demos or more information.
