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
