The APx585 is a dedicated eight-channel 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 two input channel configurations, the 8 input channel APx585 or 16 input channel APx586, these analyzers can make 14 measurements in 7 seconds on up to 16 simultaneous channels, automatically generating a measurement report and saving all test settings in a single, shareable project file.

• One click measurements and saveable sequences
• Analog I/O >90 kHz BW: 8 or 16 channels in / 8 channels out, balanced & unbalanced
• Digital I/O up to 192 kHz sample rate: 2 channels in/out via Balanced AES/EBU, Unbalanced SPDIF, and Optical TOSLink
• Digital Serial I/O Option - 8 channel digital serial I/O for I2S / I8S interfaces
• HDMI Option - 8 channel I/O with metadata monitoring and recording
• Real-time signal monitors including residual THD+N in oscilloscope or spectrum view
• New high and low pass and weighting filters, automated reference levels, and playback-only test capability
• Documented API library support for .NET languages
• USB computer interface
