The APx555 is a two-channel audio analyzer which is recognized as the standard of the audio industry. With a typical residual THD+N of -120 dB and over 1 MHz bandwidth, the APx555 surpasses the analog performance of all other audio analyzers, including a 5 dB improvement compared to the 2700 Series analyzer. Add to this FFTs of 1.2 million points and full 24-bit resolution, and you have performance unmatched by any other instrument.
APx555 has two balanced and two unbalanced analog inputs and outputs plus 216k digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. Additionally, I/O may be expanded with optional Digital Serial, HDMI with ARC, PDM and Bluetooth modules.
SYSTEM REQUIREMENTS:
Microsoft Windows 10 (64-bit) operating system.
USB 2.0 or USB 3.0. Two are required for optional switcher or DCX-127 use.
Intel i5 or better processor running at a clock speed of at least 2.5 GHz. AMD processors with similar specifications are also supported.
At least 8 GB RAM. 16 GB is highly recommended internet connection or CD-ROM drive (to access APx500 software for installation).
At least 1.5 GB of free hard disk space. An SSD for the operating system drive is recommended.
A color monitor and video card with at least SXGA (1280 X 1024) video graphics support. Video resolution of 1900 x 1080 or greater is recommended.
