APx517B Acoustic Analyzer
The Audio Precision APx517B Series acoustic audio analyzer is specifically designed, configured and priced to meet production-line needs. It is ideal for testing speakers, microphones, headphones, headsets and the wide range of consumer electronics incorporating speakers and microphones.
As an integrated system combining audio analyzer (signal generation and acquisition), power amplifier, headphone amplifier and microphone power supply, along with any required digital interface such as Bluetooth, the APx517B drastically reduces setup and reconfiguration time by eliminating multiple individual components and their cabling. A module slot accepts a single APx digital interface module such as Bluetooth, PDM or HDMI.
Key Features
- Integrated 35 W mono power amplifier and stereo headphone amplifier
