For electro-acoustic test applications, the APx1701 Transducer Test Interface combines instrument-grade amplifiers and microphone power supplies for designers and production test engineers seeking clear insight into the behavior of loudspeakers, headphones and microphones. An acoustic test accessory, it is directly integrated with APx500 audio measurement software and requires an APx B Series analyzer.

APx500 Flex Audio Analyzer & 3rd-Party Audio InterfacesAPx500 Flex Audio Analyzer

Any ASIO-enabled audio interface should suffice with APx500 Flex. However, AP has thus far verified the compatibility of the audio interfaces listed below and configuration templates for these devices are included in APx500 software (v5.0.2 or later). Guides for setting up Flex with one of these audio interfaces are also available (see the Downloads tab on the APx500 Flex product page). Each of these verified compatible interfaces offer quality analog I/O (<90 dB THD+N, 192 kHz SR) and stable drivers with consistent delay. Please contact the manufacturers, or their authorized resellers, for more information.
