Description
Audio Precision APx515B
The B Series APx515 is a performance audio analyzer optimized for production test. It is a best-in-class instrument, offering a powerful combination of speed, performance, automation, reliability and ease-of-use.The B Series APx515 can make all key audio measurements in less than three seconds. Despite its low cost, APx515B still has excellent performance, with a typical THD+N of –106 dB, 1.2M point FFTs and up to 216k digital I/O, as well as the one-click automation and ease-of-use of all APx B Series audio analyzers. Like all AP instruments, APx515B comes with an ISO:17025 Accredited Calibration and three-year warranty, so its results are trusted everywhere.
The B Series APx515 operates either as a stand-alone test unit with its own user interface, or it can be controlled by a master .NET or LabVIEW application. In either case, an operator can control the APx515 with a keyboard, foot switch or barcode scanner, or the system can be totally automated. Switchers and external devices such as pass/fail lights are also supported.

Options
Audio Precision APx515B
AES/SPDIF (APx515 standard) Provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O.
ASIO (APx515 option) Direct connection to ASIO-enabled devices. Supports up to 16 channels of ASIO at one time (with v4.0 software or later; two channels only when using earlier APx software versions). Requires either APX-SW-ASIO or APX-SWB-2 software options.
SOFTWARE
Electro-Acoustic Production Test (SW-SPK-PT) The SW-SPK-PT option enables high-speed production test of electro-acoustic devices, providing key loudspeaker measurements in a single one-second sweep. Results include Rub & Buzz detection, essential Thiele-Small parameters, and impedance magnitude and phase. A proprietary modulated noise measurement is also provided to aid in detecting enclosure air leaks.
Electro-Acoustic R&D (SW-SPK-RD) The SW-SPK-RD option delivers a complete suite of measurements and results tailored to the needs of designers and engineers developing electro-acoustic audio products. It includes key measurements and results such as complete Thiele-Small characterization; time-gated, quasi-anechoic Acoustic Response; Impedance analysis; plus the Loudspeaker Production Test measurements.
High-Speed Test (SW-HST) SW-HST adds high-speed multitone and continuous sweep measurements to the APx515.
Advanced Measurement Library (SW-AML) SW-AML is a library of 17 measurements to increase your APx515’s capabilities, including the addition of IMD, Maximum Output Level, dynamic range, and FFTs.
Acoustic Response (SW-ACR) This option adds five measurements for acoustic response testing with the APx515.
ASIO Interface (SW-ASIO) SW-ASIO adds software connectivity for PC audio interfaces to the APx515. Supports up to 16 channels of ASIO at one time (with v4.0 software or later; two channels only when using earlier APx software versions).
Bench Mode (SW-BEN) SW-BEN adds Bench Mode capability to the APx515 (requires APx515 Software Bundle (APX-SWB-2))
POLQA Perceptual Audio Test (SW-POLQA-2) Perceptual audio measurement returns a subjective assessment of speech quality using the next-generation POLQA algorithm for wide-band speech devices or devices with acoustic coupling. (Successor to PESQ with support for HD Voice, 3G, 4G/LTE and VoIP technologies)
PESQ Perceptual Audio Test (SW-PESQ) Widely-used, enhanced perceptual measurement for subjective assessment of speech quality on low-bandwidth devices. (PESQ algorithm)
APx515 Software Bundle (APX-SWB-2) Combines the ACR, AML, ASIO and HST software options for APx515 into a single, cost-effective bundle. ASIO option supports up to 16 channels at one time (with v4.0 software or later; two channels only when using earlier APx software versions).
Speech Transmission Index (SW-STI) SW-STI is a plug-in for conducting Speech Transmission Index (STI) measurements using the STIPA method.
