A few reasons why our products are the first choice among demanding audio professionals.
CHIP-LEVEL CONNECTIVITY The PSIA supports more digital serial interfaces than any other interface in the world. The APx Digital Serial I/O supports 8 channels of simultaneous audio data on TDM or multiple data lines.
MULTICHANNEL OPTIONS The APx family has native 2, 4, 8, or 16 channel options for super fast test of multichannel power amps, etc. Supported by 2700 Series, ATS-2, and APx instruments.
AUTOMATION SUPPORT AP instruments are designed with automation in mind. Various models can be connected with LabVIEW, AP Basic, .NET, or GPIB.
HDMI CONNECTIVITY The APx585 with HDMI is the ONLY audio analyzer in the world with HDMI support.3 Year Warranty & Support Audio Precision offers a full line of audio analyzer equipment, filters and accessories for R&D and production line audio test and measurement. Every instrument is backed by a 3 year warranty and free tech support for the life of the instrument. All instruments also have an optional Extended Warranty available which adds two additional years to the standard three years (US customers only).
The 2700 Series is designed for audio engineers who need the highest performance, lowest distortion and greatest flexibility possible in their audio analyzer. The typical THD+N of the 2700 Series is ≤115 dB at 2.0 Vrms. However, even with AP's conservatively specified THD+N of -112 dB, the 2700 Series is the industry's undisputed performance leader.

The APx525 Family is the next generation of high performance audio analyzers
for R&D engineers and production technicians.
With typical THD+N at –108 dB
( –110 dB with AG52 option),
analog performance is second only to the 2700 Series in the world.

Portable One audio analyzers bring bench-quality, high-precision test and
measurement to maintenance, engineering and production facilities. Whether
in broadcast, communications, bench or production use, Portable One offers a
complete, easy-to-use audio test set housed in a rugged clamshell case that’s ready
for almost anything. ATS-1 offers the same functionality, but is housed in a metal
case for rack mounting.

The next-generation APx interface allows 1 click measurements from a list of common audio measurements for the fastest and easiest audio test in the world.
MULTITONE, CONTINUOUS SWEEP, BIT STREAM ANALYSIS, MLS AP's multitone is optimized for very fast production test. And continuous sweep technology lets you take 14 measurements in 7 seconds.
USER-DEFINED SWEEPS User defined sweeps in 2700 Series and ATS-2 allow every conceivable measurement to be made.
FFTS UP TO 1 MILLION POINTS APx has the highest resolution FFTs in audio, allowing detailed visual analysis of signals.
LOWEST THD+N & CROSSTALK At -112 dB, 2700 Series analyzer has the lowest THD+N in the world. The analyzer with second lowest THD+N in the world is the APx525. Crosstalk in both is so low it cannot be measured.
FLATTEST RESPONSE At ±0.0008 db, no analyzer in the world has flatter response than APx. 
WIDEST BANDWIDTH & DYNAMIC RANGE The APx525 measures down to .01 Hz and can handle inputs up to 240 V, allowing nearly every amplifier in the world to be tested at full scale with total confidence. No other analyzer in the world can do this.
ACCREDITED CALIBRATION AP is accredited by A2LA under ISO/IEC 17025:2005, the most stringent standard. Calibration provides documented and traceable verification that instruments meet or exceed all of their published specifications.
