With a breakdown power of 100 watts (at 8 ohms), the RX-A870 is powerful enough for large rooms and all types of speakers. Dolby Atmos uses speakers to create multidimensional, immersive sound that's right for the best movie theaters. Also provides amazing power, compatibility with high definition audio. This gives a sound that is much more natural than standard. The receiver supports DSD 2.8 MHz / 5.6 MHz, FLAC / WAV / AIFF 192 kHz / 24 bit and Apple Lossless 96 kHz / 24 bit for wide file playback.

Design and build

7.2-channel AV receiver Aventage is of exceptional design quality. Anti-resonance technology (ART) makes this AVR extremely resistant to mechanical and electrical noise. ART includes a frame with transverse H-shaped elements and a rigid chassis with additional lower frames, anti-vibration radiators, which gives the RX-A870 excellent detail and resolution.
