2700系列是专为音频工程师谁需要最高的性能，最低的失真和最大的灵活性，在他们的音频分析仪。借助可编程串行接口适配器（PSIA），它是高端转换器和其他芯片设计人员的最佳解决方案。，2722’真正的双域结构使模拟和数字信号的测量实现了完美：模拟发生器和分析仪的性能优于任何基于数字转换器的设计，而数字分析技术为这两个领域提供了一系列精确、高速的测量技术。跨域工作可以使用两个世界的最好的来完成。，2700系列的典型THD+N是♁15 dB，2.0 Vrms。然而，即使AP’保守地规定THD+N为-112 dB，2700系列仍然是业界无可争议的性能领导者。

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.

APx515是为生产测试优化的高性能音频分析仪。APx515具有典型的THD+N为–106 dB、具有24位分辨率的100万点FFT和192K数字I/O。它以其速度、性能、自动化和易用性是一流的仪器。APx515是一款重要的产品，因为它以生产级的价格提供音频精度的性能和可靠性。，APx是世界上速度最快的音频分析仪，在1.2秒内返回21个音频测量值。它也是最容易使用的，具有一键式测量、自定义报告和复杂的自动化，无需任何编程。还提供了完整的API和LabVIEW驱动程序。，这种速度和易用性意味着测试永远不会成为瓶颈，生产线经理可以获得可靠、一致的结果，与当前的低成本替代品（如失真分析仪）相比。，对于外包生产的公司，要求APx515进入生产线，可以更严格地控制生产，确保制造商满足合同要求。

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.

APx585是一个真正的多声道音频分析仪，有8个同时模拟输出和输入。它是设计和测试消费类设备（如家庭影院接收器）或专业设备（如混音控制台）的理想选择。APx586在中为16个同时模拟信道添加了第二个输入模块。两种型号都有192K数字输入和输出通过AES\/EBU，TOSLINK和SPDIF。，此外，I\/O可以通过可选的数字串行（APx585和APx586）、带ARC的HDMI（APx585）和Bluetooth（APx585）模块进行扩展。，没有其他音频分析仪可以更快或更容易地用于多声道音频。
