APPLICATION

A2 is a cost-effective analog 2-channel audio analyzer developed by Eptec, its system performance and functions are between A5 and A1DD, supporting a variety of electroacoustic test options and digital interface (BT/HDMI/I2S) expansion, is a cost-effective solution for primary development and production line testing of consumer audio products.

8-channel passive low-pass filter, mainly used for audio measurement of Class-D amplifier. It can provide audio out of band attenuation and reduce the steepness of fast conversion edges, providing signal preprocessing for testing accuracy. It has a passband of 20-20kHz and is designed specifically for use with the A8 series audio analyzers.

A10 is currently the most high-performance and fully functional analog 2-channel audio analyzer, fully benchmarking with AP company APx555. It has a high-performance sine signal generator and analyzer, which can generate sine signals up to 204kHz and residual THD+N of less than -120 dB in the system. It has a testing bandwidth of over 1MHz and supports all digital interfaces (ADIO/BT/I2S/HDMI/PDM) and advanced master clock (AMC) modules. It is an ideal testing equipment for the development stage of audio products.

A9 is a 16 channel audio analyzer with analog 8 channel output/16 channel input, fully aligned with AP's APx586, and its interface type and channel range meet a wide range of audio product testing requirements. In addition, it supports digital interfaces (AES/EBU/TOSLINK/SPDIF) with a sampling rate of up to 216K, as well as extensions such as BT/I2S/HDMI/PDM, making it an ideal testing device for multi-channel (8-channel or above) audio products.

A8 is a true multi-channel audio analyzer, which supports analog 8-channel simultaneous input/output and digital interface (BT, I2S, HDMI, PDM, etc.) expansion. It is an ideal test equipment for consumer equipment such as home theater receiver/professional Mixing console, etc.

A7 is an audio analyzer with flexible input and output interfaces, supporting analog 2-channel output, 8-channel input, and various digital interface (BT, I2S, HDMI, PDM) extensions. It is a testing equipment for multi-channel audio products. The analog 2-channel output characteristics enable it to have higher performance and output amplitude, meeting the high input requirements of the tested product.

A6 is a 4-channel audio analyzer with 2 channels of analog output/4 channels of analog input, as well as a digital interface (AES/EBU/TOSLINK/SPDIF) with a sampling rate of up to 216K, designed specifically for typical 4-channel power amplifiers in the automotive audio industry. In addition, the input output interface can be extended through optional digital modules such as DSIO/PDM/BT/HDMI.

A5 is a high-performance analog 2-channel audio analyzer developed by Aptec, fully benchmarking with AP company APx525. In addition to having ultra-high system performance, it also provides a series of testing plugins to expand testing capabilities, and supports multiple digital interfaces (BT, I2S, HDMI, PDM, etc.). It is a testing equipment for the development stage of consumer audio and automotive electronics and other audio and video products.
