An 11.2 channel AVENTAGE AV receiver from Yamaha. Yamaha rates it at 150 W per channel into 8 ohms (20 Hz-20 kHz, 0.06% THD, 2 channels driven) and lists SURROUND:AI, Dolby Atmos, DTS:X, Auro-3D, 7 HDMI inputs and 3 outputs with 8K/60Hz and 4K/120Hz, dual ESS SABRE ES9026PRO DACs, XLR inputs, AirPlay 2 and MusicCast.
THIS IS A REFURBISHED MODEL. 30 MONTH WARRANTY APPLIES, ITEM MAY NOT COME IN ORIGINAL BOX/PACKAGING
Yamaha describes the RX-A8A as its most innovative model yet. It says the receiver uses the concept, architecture and materials of the CX/MX-A5200, with a double bottom plate and thick copper foil on the circuit board for lower impedance.

Why you will love it
Construction from the CX/MX-A5200 concept
Yamaha says the A8A uses the concept, architecture and materials of the CX/MX-A5200. It lists a double bottom plate to stabilise against unnecessary vibration, thick copper foil on the circuit board for lower impedance, a customised capacitor and 11 channel capability.
Yamaha also lists a High Slew Rate amplifier and the A.R.T. Wedge.
SURROUND:AI, Dolby Atmos, DTS:X and Auro-3D
Yamaha says SURROUND:AI analyses the scene and optimises the surround effect for sound elements such as background music, dialogue and sound effects. It runs on 64-bit processing with a Qualcomm QCS407.
The RX-A8A supports Dolby Atmos with Height Virtualizer, DTS:X and Auro-3D, plus CINEMA DSP HD3 with 24 DSP programs.
Dual ESS SABRE ES9026PRO DACs and amplifier
Yamaha lists two ESS SABRE ES9026PRO DACs (384 kHz / 32-bit). It says they help minimise noise and give a high signal-to-noise ratio and dynamic range.
Yamaha rates the amplifier at 150 W (8 ohms, 20 Hz-20 kHz, 0.06% THD, 2 channels driven) and 185 W (8 ohms, 1 kHz, 0.9% THD, 1 channel driven).
8K, 4K/120Hz and gaming
The receiver has 7 HDMI inputs and 3 outputs (HDCP 2.3), with eARC. Yamaha lists HDMI pass-through of 8K60AB and 4K120AB (40 Gbps), up-scaling to 8K, Dolby Vision, HDR10+, ALLM and VRR.
Yamaha says QMS (Quick Media Switching) cannot be added to these receivers by firmware.
YPAO room correction
Yamaha says YPAO-R.S.C. (Reflected Sound Control) calibrates the sound to your room by analysing room acoustics and measuring speaker characteristics. Yamaha lists 3D, multi-point measurement, 64-bit high precision EQ calculation and angle measurement.
Yamaha says it also optimises sound parameters for SURROUND:AI, Dolby Atmos and DTS:X.
Zones, pre-out and XLR inputs
Yamaha lists Zone 2, Zone 3 and Zone 4 (Zone 4 through HDMI), with Zone 2 and Zone 3 powered. An 11.2 channel pre-out is fitted, and XLR balanced audio inputs are listed.
Dedicated phono input terminals let you connect a turntable.
MusicCast, AirPlay 2 and wireless rear speakers
The RX-A8A has Wi-Fi (2.4 / 5 GHz), Ethernet, Bluetooth (SBC / AAC) and AirPlay 2. Yamaha lists Spotify Connect and MusicCast multi-room audio, controlled with the MusicCast app.
Yamaha says it is compatible with MusicCast 20 or MusicCast 50 wireless speakers as rear speakers.
Is it right for you?
A great fit if you…
- Want 11 amplified channels with Dolby Atmos, DTS:X and Auro-3D
- Want XLR inputs and analogue video inputs alongside HDMI
- Plan to add an external power amplifier through the 11.2 channel pre-out
- Want to feed several rooms with Zone 2, 3 and 4
Worth knowing
- It is a large receiver. It weighs 21.4 kg and is 435 mm wide and 477 mm deep (271 mm high with the antenna up), so check your shelf
- Yamaha says QMS (Quick Media Switching) cannot be added to these receivers by firmware
- Zone 4 is an HDMI zone. Powered zones are Zone 2 and Zone 3
Build your system
The RX-A8A needs speakers. Rear and height speakers can be wired or wireless.
