The 2700 Series is designed for audio engineers who need the highest performance, lowest distortion and greatest flexibility possible in their audio analyzer. With the Programmable Serial Interface Adapter (PSIA), it is the best solution for high end converter and other chip designers.

The 2722’s true dual domain architecture enables uncompromised measurement of both analog and digital signals: the analog generator and analyzer performance surpasses that of any digital converter-based design, while digital analysis techniques offer a wide array of precise, high-speed measurement techniques for either domain. Cross-domain work can be accomplished using the best of both worlds.

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.

• Dedicated analog circuitry for vanishingly low residual noise and THD+N
• 192 kHz digital input and output capabilities
• Generates and analyzes a broad palette of stimulus signals such as MLS, white and pink noise and other special purpose waveforms
• Extensive API automation with AP Basic scripting and “learn mode”, LabVIEW driver and an IEEE.488 GPIB interface
• User-defined sweeps, switcher support up to 192 channels

The APx515 is a high performance audio analyzer optimized for production test. APx515 has a typical THD+N of –106 dB, a one million point FFT with 24-bit resolution, and 192K digital I/O. It is a best-in-class instrument for its speed, performance, automation, and ease-of-use.

APx515 is a significant product because it delivers the performance and reliability of Audio Precision at a production-level price.

APx is the fastest audio analyzer in the world, returning 21 audio measurements in as fast as 1.2 seconds. It is also the easiest to use, with one-click measurements, custom reporting and sophisticated automation without any programming. A full API and LabVIEW driver is also provided.

This speed and ease-of-use means test will never be a bottleneck, and production line managers can achieve reliable, consistent results compared to the current low-cost alternatives like a distortion analyzer.

For companies outsourcing their production, requiring APx515 on the production line gives tighter control over production, ensuring manufacturers are meeting their contractual requirements.

AUDIO PRECISION QUALITY FOR HEARING INSTRUMENTS

The audio analyzer designed specifically for the needs of hearing instrument manufacturers.

The APx511 Hearing Instrument Audio Analyzer is designed to meet the needs of hearing instrument manufacturers, providing the specific measurements and I/O required for hearing instrument production test, delivered with Audio Precision’s reputation for high performance and reliability.

All APx models use the same software, so with the R&D department using an APx525 or APx585 and APx511 deployed on production lines, product design is faster, interaction between Engineering and Production is easy and the AP report generated by Quality Control is trusted around the world.
IEC60118-7 / ANSI S3.22 function library

APx511 supports a .NET library of functions that automate the tests described in IEC60118- 7 and ANSI S3.22. For the production environment, these functions can be called from any .NET capable language or LabVIEW to control the APx511’s output and measurement settings.

For troubleshooting or test setup, the APx511 can be controlled by the standard APx500 software providing a rich graphical user interface and access to automated reporting, real-time signal monitors, high resolution FFTs and controls for limits & other settings.

In addition to standard audio tests such as level, distortion, frequency response, and attack & release, APx511 can measure battery current using its built-in battery simulator circuit.

Built-in support for test chamber speaker, telecoil & microphone

The APx511 generator includes an in-line 2 watt loudspeaker amplifier (8 ohms) and a telecoil amplifier, allowing >110 dB SPL and up to 400 mA/m field strength from 100 Hz to 10 kHz in a test chamber such as the Interacoustics TBS25. On the input side, APx511 supplies 24 V DC of constant current through a single BNC for a pre-polarized measurement microphone.

The APx585 is a true multichannel audio analyzer, with 8 simultaneous analog outputs and inputs. It is ideal for designing and testing consumer devices such as home theatre receivers or pro devices such as mixing consoles. The APx586 adds a second input module for 16 simulaneous analog channels in. Both models have 192K digital inputs and outputs via AES/EBU, TOSLINK and SPDIF.

Additionally, I/O may be expanded with optional Digital Serial (APx585 and APx586), HDMI with ARC (APx585), and Bluetooth (APx585) modules.

No other audio analyzer is faster or easier to use for multichannel audio.

• Super fast testing of a wide range of multichannel devices
• Measure one-to-many or many-to-one crosstalk & phase across all channels
• Measure maximum power across all channels over time
• Supports switchers for 192 maximum channel capacity

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. APx526 is the four channel version of the APx525, developed for the 4 channel head units typical of the automotive audio industry.

Additionally, I/O may be expanded with optional Digital Serial (APx525 and APx526), HDMI with ARC (APx525), and Bluetooth (APx525) modules.

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.
