These terminals support the BT.2020 4K video standard, 4K/60 Hz playback, and HDCP 2.2.

AccuEQ sets speaker distance, SP level, and crossover. In addition, AccuEQ Advance employs multi-point measurement to remove standing waves from your listening space, which compromise audio quality and bass response. The technology also detects and compensates for background noise, such as the hum from an HVAC, to ensure accurate equalization. 

AccuReflex technology aligns the phase of up-firing "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object-based soundtracks.

With a 5.2-ch theater layout in Zone 1 (Main), the remaining four channels can drive speakers in Zone 2 and Zone 3. As well as analog distribution, dedicated DACs enable digital sources* to be synced across rooms simultaneously, or a unique source to be played in every zone at once. Zone 2 and Zone 3 line-level outputs are ideal for sharing sources to existing hi-fi systems. 

* Audio via HDMI inputs and S/PDIF audio not supported in Zone 3.

The DAA philosophy places less emphasis on lab measurements and more on how the sound actually feels in real life. High-current drive and expert tuning deliver natural transient response, the key to involving sound. A deep power reserve arrives instantly when action explodes on screen, adding adrenaline to the film experience. Accuracy and control is maintained with custom transformer and custom block capacitors, aluminum heat sink, non-phase-shift amp circuitry, and discrete output transistors. With VLSC™ noise filtering (Front L/R) for improved fidelity, DAA is built for compelling sound.

Onkyo's dynamic audio amplification delivers massive power at 225 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)/ 100 W/Ch (8 Ohms, 20 Hz-20 kHz, 0.08% THD, 2 Channels Driven).

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 Onkyo RZ Series was designed for home theater integration and performance above and beyond your expectations. From multi-zone audio and video options to dedicated RZ Series phone support and a three-year product warranty, the Onkyo RZ Series delivers superior audio performance in the configurations you want with the support you should expect from the leader in home audio.
