The APx is a dedicated multichannel audio analyzer that combines an application-oriented user interface with multi-channel audio test. It's the perfect audio analyzer for production test users who need speed and ease-of-use.

Available in an 8 or 16 channel configuration, the APx is capable of taking 14 measurements in 7 seconds, automatically generating a report of results and saving all test settings in a single, sharable project file.

• One click measurements and saveable sequences
• Analog I/O: 8 or 16 channels in / 8 channels out, balanced & unbalanced
• Digital I/O: 2 channels in/out via SPDIF and Optical TOSLink
• Real-time signal monitors including residual THD+N in oscilloscope view and one million point FFT
• New high and low pass and weighting filters, automated reference levels, and playback-only test capability
• Documented API support for .NET languages

It has the best performance of any audio analyzer in the world.
