Summary: APx521 and APx526 round out APx family with 2, 4, 8 or 16 channel models now available

AES, San Francisco – Oct 3, 2008 – Audio Precision, the recognized standard in audio test, today unveiled two new four-channel models of its award-winning APx500 Series audio analyzer. The APx521 and APx526 offer the same performance, high speed and one-click measurements as the APx520 and 525, but with four analog input channels instead of two. The APx526 includes a digital I/O.

APx521 and APx526 are ideal for testing automotive audio systems, which typically have two analog inputs and four outputs, often with digital inputs. Analog performance of both models is second only to AP’s 2700 Series, with a typical THD+N of -108 dB (at 1 kHz, 2.5V). For systems with higher channel counts, the APx585 or APx586 are recommended.  

With the addition of these new models, AP now offers audio engineers and production testers a choice of 2, 4, 8, or 16 channels so they can configure the ideal analyzer for their requirements without compromising features or performance.

“When we introduced the two-channel APx models in May, our automotive customers were impressed, but they immediately came back and said they needed four channels,” said Bruce Hofer, Co-founder and Chairman of Audio Precision. “AP has always been very responsive to our customers’ requests, so I’m happy to declare that, true to form, we have provided what was asked for.”
