AB-ADIO Option
The advanced digital interface module AB-ADIO provides AES3 and AES/EBU balanced digital input/output interfaces on the XLR port, unbalanced SPDIF digital input/output interfaces on the BNC port, and fiber optic digital input/output interfaces on TOSLINK. In addition, the ADIO module can generate advanced interface damage signals and perform complex testing on devices through AES/SPDIF/TOSLINK. It also includes an advanced master clock module AMC, which is used to process input and output clock signals and synchronize with external devices. It can also generate and test jitter signals for interface modules that support jitter (ADIO, DSIO, HDMI, etc.).

Filter 20K
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.

AB-AG52 Option
The high-performance analog signal source option AB-AG52 is developed specifically for amplifier designers, capable of generating extremely pure square wave signals with a rise time of less than 2 microseconds and increasing the system THD+N to -110dB (typical value). AG52 can generate square wave and sine wave signals specified by DIM 100, DIM 30, and DIM B, and increase the maximum output level of the balanced interface from 21.21 Vrms to 26.66 Vrms. This option is suitable for instruments equipped with analog 2-channel output (A5/A6 are options, A7/A10 are standard)
MORE
AB-BW52 Option
The high-performance analog analyzer option AB-BW52 has an ultra-high bandwidth option, providing advanced FFT performance and high-resolution analog input bandwidth up to 1MHz. This option is suitable for instruments equipped with analog 2-channel inputs (A5/A6 options, A10 standard)

Audio analyzer A9 series
The A9 is a true multi-channel audio analyzer with 8-channel analog output and 16-channel analog input. Its interface types and channel count meet a wide range of audio testing requirements, and it supports interface expansions such as BT, I2S, HDMI, PDM, ADIO, AMC, and A2B, making it an ideal testing device for multi-channel audio products.
In addition, by recombining the analog and digital interface modules of the A9, more model config-urations can be obtained, such as A9-01/02/03/04, etc. Different models support different numbers of analog input channels, with a maximum of 32 channels, meeting the testing requirements of current high-channel-count products such as car power amplifiers and professional audio power amplifiers.
