AECM206 Headphone Test Fixture

AECM206 Headphone Test Fixture

IEC 60318-4-compliant accessory simplifies earbud and headphone measurement in lab and production environments

The AECM206 Headphone Test Fixture is a dense, robust fixture mounted on a resilient base to isolate ambient noise, which can adversely affect measurement integrity. Equally capable in both R&D and production test applications, it is well-suited for testing circum-aural, supra-aural and intra-concha headphones and earbuds. The AECM206’s high level of acoustic isolation also enables the measurement of noise-reduction performance of ANC (active noise canceling) headphones, as well as the evaluation of hearing protection ear muffs.

The AECM206, in conjunction with APx Series analyzers, accessories and software, provides the user with a complete system enabling precise and repeatable electro-acoustic testing of headphones and insert earphones (earbuds).

The Headphone Test Fixture is shipped fully-assembled and ready to use upon arrival, with occluded ear simulators (microphones with acoustic couplers) and preamplifiers installed and connected to BNC-terminated coaxial cables. The microphone/preamplifier pairs are TEDS-compliant, CCP-powered and calibrated. TEDS—Transducer Electronic Data Sheet—programming allows microphone identification and calibration information to be read by a connected instrument, such as the Audio Precision APx1701 Transducer Test Interface.

APx Bluetooth Duo Module

Audio Precision - APx555 Audio Analyzer with Bluetooth Duo

The Audio Precision Bluetooth Duo option is a completely revised, upgraded Bluetooth® hardware module, with dedicated source and sink radios, new Bluetooth chips and the latest firmware, higher RF power, and improved RF shielding. Supported by Audio Precision’s APx500 measurement software (NOTE: version 4.5 or later required), Bluetooth Duo offers a range of new audio codecs, new operational features in the supported profiles, and faster connection times. The option can be installed into any APx modular analyzer manufactured later than mid-2012. (AP’s legacy Bluetooth module is available for earlier generations APx analyzers or cases where APx500 software v4.4.2 or earlier is required.)

As an APx module, Bluetooth Duo is part of an all-in-one solution, integrated into the analyzer and leveraging the power and flexibility of the APx system. Bluetooth Duo can share the analog, digital, chip-level I2S and TDM protocols, PDM, or HDMI input/output capabilities installed in the analyzer. Intuitive and powerful, the APx500 software provides access to a long list of audio measurements and Bluetooth settings and parameters. APx creates logs of sent and received commands and interactions, and can easily automate Bluetooth I/O, connection, pairing, and settings commands in a stepped sequence for production work. When new Bluetooth features and improvements are made available, Bluetooth firmware upgrades can be distributed and installed in the field.

APx555 Audio Analyzer

Audio Precision - APx555
High-Performance, Modular 2-Channel Audio Analyzer

The APx555 is Audio Precision flagship product and the new standard for audio analyzers. Built without compromise, it is developed for R&D engineers and production technicians who need the highest possible performance with a broad range of I/O options.
The APx555 unprecedented electrical & acoustic signal analysis performance can be see from its typical residual THD+N of -120 dB and over 1 MHz bandwidth. It is coupled with a FFTs of 1.2 million points and full 24-bit resolution making it superior to any other Audio Analyzer.
APx555 comes standard with two balanced and two unbalanced analog inputs and outputs and 216k digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. It is customizable with additional Digital Serial, HDMI with ARC, PDM and Bluetooth I/O can be added on via various modules for the customers testing needs.
Similar to all APx series, the APx555 comes with an Advanced Master Clock (AMC) module to handle input and output clock signals to synchronize the APx555 with external equipment (or vice versa) and allows the APx555 to do jitter generation and analysis.
