the receiver also features an FM/DAB+ tuner, internet radio, and inputs for turntable and CD. Peek under the hood and 
you’ll find a fully customized EI transformer powering Onkyo-original Switching Amplifier technology. High-grade audio 
circuit boards are packed with proper top-quality audio components including two huge capacitors that deliver loads of 
oomph and deep, powerful bass. Housed in a super-rigid full-flat metal chassis reinforced by a solid aluminum faceplate, this 
amp is built heavy for seriously good full-scale sound.

R-N855
 Network Stereo Receiver
Hi-Fi Performance from a Compact Body
Onkyo’s in-house-developed Switching Amplier technology 
delivers high power with vanishingly low distortion from a 
physically small receiver. Powered by a custom transformer 
and huge audio capacitors, the discrete modulation stage 
delivers exceptionally clear and musical sound, even with 
difcult-to-drive or sensitive speakers.
Super-Rigid Construction Reects a Premium Build
The amp system and audio circuit boards are housed in a 
rigid, 1.6 mm-thick full-at metal chassis further stiffened by a 
solid aluminum faceplate. Together with anti-resonant insulator 
feet, vibrations that cause interference on audio signals are 
virtually eliminated, improving clarity.
Cast Music from Mobile and PC 
Google Cast™* and AirPlay® included on the receiver let you 
cast audio from a variety of suppor ted applications for iPhone, 
iPad, and Android 
Chromebook computers) in seconds. Bluetooth 
technology is also included.
* Service enabled via rmware update TBA.

Select, Play, and Update Music Stored on a 
Connected HDD
Load your entire digital library onto an HDD*, connect it to 
one of the receiver’s USB inputs, and use our smartphone 
app to browse and play anything in your collection complete 
with album art and song information.  
A future rmware update will enable full 
music server capability with audio les 
writable to HDD via personal computer.
* HDD must be formatted to FAT32. Onkyo cannot 
guarantee, nor has tested for, correct operation with all HDD 
device types and brands.
Hi-Res Audio via Network or USB
The R-N855 receiver features a premium AK4490 768 kHz/ 
32-bit DAC to conver t digital signals into a smooth analog 
waveform. This DAC module is renowned for high 
bandwidth and low noise, and decodes 11.2 MHz 
DSD and 192/24 PCM Hi-Res Audio formats over 
network or USB. 
VLSC™ Reduces Noise and 
Reveals Detail
Pulse noise arises when converting 
digital signals to analog. The R-N855 
features VLSC (Vector Linear Shaping 
Circuitry), a unique technology that 
analyzes input and output signals and 
erases noise, clarifying details otherwise 
hidden in subtle distortion.
VLSC reshapes the signal by 
generating an original signal 
line (vector). 
Supports FireConnect™* Multi-room Audio
Place optionally available wireless speakers in other rooms of 
your home to enjoy any source connected to your R-N855 
Stereo Receiver (even your LPs) and have music wherever 
you go thanks to FireConnect
* Multi-room audio is realized by FireConnect™, a wireless technology by Blackre 
Research Corp., USA. We do not guarantee this product will work with all FireConnect™compatible speakers. Optional speakers are scheduled for release. Available sources 
are model-dependent.
