SPECIFICATIONS
Dynamic Audio Amplification
Refined over 70 years to deliver emotion in high fidelity,
DAA features a custom High-Current Low-Noise Power
Transformer, customized capacitors, and discrete amp output
stages. Unique topology prevents phase-shift while high current
improves speaker control for true dynamic speed. Driving
4-ohm loads through all channels, DAA has power to move.
New upgrades reduce noise and boost power
The TX-NR797 adds new refinements that control noise,
boost power, and improve S/N performance. A new
HDMI® board has shorter signal-paths and large, carefully
finished grounds for clean A/V signals. SoC is isolated to
reduce interference noise.
The power-supply line is
strengthened in pursuit of
power and the results are
evident in improved speed,
force, and localization across
an expanded soundstage.
Whole Home Audio, just add speakers
Orchestrate playback of different audio sources in up to three
rooms at once from your smartphone. The TX-NR797 has
nine amplifier channels and two zone audio DACs supporting
D/A audio distribution via Zone 2 and Zone 3 outputs,
including HDMI®/SPDIF/NET/Bluetooth®, and supports a
variety of speaker layouts including 5.2.2-ch Main + Zone 2, or
5.2-ch + Zone 2 + Zone 3.
Note: HDMI and SPDIF support PCM audio only. Zone 2 HDMI audio available on
inputs 1–3. Zone 3 supports analog/NET/Bluetooth.
Quad-core SoC supports 802.11ac Wi-Fi®
A powerful SoC (System on a Chip)
processes multiple tasks at once. It evolves
network functions and supports the
latest high-speed 802.11ac (2x2 MIMO)
specification while compatible with
802.11 b/g/n dual-band routers.
Note: Some countries or regions have regulations that affect wireless signal strength
and the use of Wi-Fi channels.
Versatile Zone 2/Zone B line-out
Connect an audio system via analog RCA input to the AVR’s
Zone 2/Zone B line-out. In Zone 2 mode, you can play the
same or different D/A sources (including SPDIF and HDMI)
in either or both rooms at the same time. Zone B mode is
an ideal match for a supported wireless transmitter. Listen to
any source—including the TV—through wireless headphones.
Perfect for midnight movies and TV.
Clarify voice dialog in-program instantly
Vocal Enhancer solves inaudible dialog in TV programs and
movies. DSP technology identifies voice frequencies so you
can adjust them using remote-control keys or controls on the
front panel.
AccuEQ Advance with AccuReflex™
AccuEQ Advance room acoustic calibration uses nine-point
measurement to remove standing waves that occur when
sound from the speakers resonates with sound reflecting off
the walls, altering its natural expression. During the process,
