With a typical residual THD+N of −120 dB and over 1 MHz bandwidth, the APx555B surpasses the analog performance of all other audio analyzers, including a 5 dB improvement compared to the legacy 2700 Series analyzer.\u003c\/p\u003e\n\u003cp\u003eAPx555B has two balanced and two unbalanced analog inputs and outputs plus digital inputs and outputs via AES\/EBU, TOSLINK and S\/PDIF. I\/O may be expanded with optional Programmable Serial, HDMI2 + eARC, PDM and Bluetooth modules. The Advanced Master Clock (AMC) module comes standard, synchronizing the analyzer with external equipment and enabling jitter generation and analysis.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 class=\"h4\"\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTypical residual THD+N \u0026lt;
