Dynamic Audio Amplification
Backed by 70 years of experience building high-grade audio components, the TX-NR555 amplifies accurate, noise-free signal processing with high-current power for dynamic speaker control. The result is pure, rich and authentic sound.
Onkyo's dynamic audio amplification delivers massive power at 140 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven)/ 80 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven).
Smooth Analog Signal
Onkyo developed Vector Linear Shaping Circuitry (VLSC) to reassemble the audio signal to its original form following processing. Unlike conventional filters, VLSC removes pulse noise generated in D/A conversion, allowing the sound wave to be reproduced with extremely high fidelity for a smooth analog signal.
The TX-NR555 Powered Zone 2 brings audio to speakers connected to the receiver into a second room. With the dedicated Zone 2 DAC, you can send internet audio sources to your second listening zone.
Supports Dolby Atmos Up to 5.1.2 Channels
Dolby Atmos moves sound around you in three-dimensional space, so you feel like you're inside the action. The TX-NR555's Dolby Atmos decoding transports you from the ordinary into the extraordinary.
Sound designers and artists mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.
Additionally, the Dolby surround up-mixer processes content not mixed for Dolby Atmos to fill the flexible speaker layouts of a Dolby Atmos system.
