Dynamic Audio Amplification with RZ Series Build

DAA stabilizes power delivery for accurate speaker control and spectacular dynamics. High-Current Low-Noise Power and spectacular dynamics. High-Current Low-Noise Power Transformer and 10,000 uF custom high-current smoothing capacitors deliver power instantly while non-phase-shift amps reproduce a wide 5 Hz-100 kHz spectrum. An extruded aluminum heat-sink controls the pitch of resonance frequencies, limiting mechanical noise. Behind the front panel are hand-selected or custom fabricated parts with digital boards separate from analog circuitry. The result is visceral musicality that makes every note an emotionally moving experience.

New upgrades reduce noise and boost power

TX-NR797 HDMI board

Additional refinements control noise, boost power, and improve S/N performance. A new HDMI® board has shorter signal-paths and large, well-finished grounds for A/V signal integrity. SoC is isolated to reduce interference noise. The power-supply line is reinforced in pursuit of smooth power delivery. These contribute to punchier bass and improved localization on an expanded soundstage.

AccuEQ Advance with AccuReflex

AccuEQ Advance room acoustic calibration uses nine-point mic measurement to calibrate and EQ speakers and subwoofers and remove standing waves that arise when sound from the speakers resonates with sound reflecting off the walls, compromising its proper expression. During the process, background noise is ignored to ensure accurate equalization. AccuReflex optimizes 3D sound through height speakers by resolving phase-shift, resulting in a cohesive sound-field.
