Audio Precision will publicly debut the new APx555 audio analyzer at the upcoming 137th AES Convention in Los Angeles, at booth 1212.
Introduced in September, the APx555 offers engineers involved in audio R&D and production test a combination of high performance, modular architecture with a broad range of digital I/O, and flexible, intuitive measurement software.
Additionally, Audio Precision will be demonstrating loudspeaker test and acoustic measurements for R&D and production applications. Demonstrations will utilize the APx515 and APx500 software, and will include key measurements and capabilities such as impedance and Thiele-Small, quasi-anechoic reflection gating, rub & buzz, and air leak detection.
With a typical residual THD+N of -120 dB and up to 1 MHz bandwidth, the APx555 surpasses the analog performance of all other audio analyzers, including a 5 dB improvement compared to the company’ SYS-2722 analyzer. This performance is supported by 1.2 million point FFT resolution.
APx500 v4.0 measurement software allows the APx555–and all other APx analyzers–to adapt to the needs and preferences of audio designers, engineers and technicians.
Sequence Mode provides complete, code-free automation of pre-defined measurement sequences to enable fast and reliable results. Bench Mode provides the real-time interface approach of the SYS-2722, allowing rapid understanding of relationships between stimulus and results. Waveforms, FFTs and meters for virtually any parameter can identify important interactions, ideal for experienced users.
The APx555 supports the complete range of APx digital I/O options, ensuring compatibility with a wide array of audio formats and devices. Options include Digital Serial (I2S, TDM, multi-line support), Bluetooth (mSBC, A2DP, SBC, CVSD, aptX, HFP 1.6, AVRCP), HDMI+ARC (source, sink and monitor, including metadata), PDM (1-bit audio generation and analysis (including PSRR), and advanced digital (AES/SPDIF/Optical).
Key features:
• Residual THD+N: -120 dB (typical)
• Up to 1 MHz bandwidth @ 24 bits
• Signal generation up to 204 kHz and 26 Vrms
