Features
 
5.1-Channel Powerful and Dynamic Surround System
The AV receiver ensures that action movies with loud, dynamic soundtracks will be heard in spectacularly realistic surround sound. The front, surround and center speakers are high quality models capable of reproducing high definition audio, and the subwoofer delivers clean, crisply powerful bass. traditional design speakers enhance any room.
 
4K Ultra HD Full Support with 4K / 60p, HDCP2.2, HDR Video and BT.2020 pass-through
This AV receiver completely supports with latest HDMI® standards. Thanks to transmission of 4K video at 60 frames per second pass-through, you can fully enjoy the high definition video quality of 4K without degradation. It also adheres to the HDCP2.2 copyright protection standard for 4K video transmission. It also supports HDR (High Dynamic Range) Video which provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. Furthermore it supports the wider colour gamut of BT.2020 pass-through. This AV receiver is also compatible with 3D, Audio Return Channel and CEC for easy operation.
 
Discrete Amp Configuration for High Sound Quality
This AV receiver was designed with a strong focus on achieving exceptionally high sound clarity. It employs a discrete amp configuration and a low jitter PLL circuit, which contribute to its excellent audio performance.
 
Compressed Music Enhancer
When music is encoded into a digitally compressed format like MP3, the frequency response suffers. Yamaha’s Compressed Music Enhancer employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should.
 
SCENE for One-Touch Start
Pressing a SCENE button powers on the AV receiver and selects the input source and DSP mode. You can re-set the buttons for different sources by selecting a source and DSP mode, then pressing a SCENE button for more than three seconds.
 
HD Audio with CINEMA DSP
Yamaha’s exclusive CINEMA DSP technology supports playback of HD Audio, providing natural and expansive sound imaging.
 
Virtual CINEMA FRONT Provides Virtual 5-channel Surround Sound with High Quality and Resolution
Even when it is impossible to install surround speakers behind the listening position, Virtual CINEMA DSP reproduces virtual 5-channel surround sound filled with realism, with only two front speakers. With Virtual CINEMA FRONT, you will enjoy virtual 5-channel surround sound with higher quality and resolution by installing surround speakers at the front. You get more flexibility to arrange your speakers inside the room, along with easy enjoyment of high quality surround sound.
 
Extra Bass Provides Rich Bass Reproduction, Even with Small Speakers
Yamaha’ s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localisation and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers, but also enhancing the bass from the subwoofer. You'll enjoy video and music with sound that has exceptional power and presence.
 
Subwoofer Trim for Improved Sound Imaging
The Subwoofer Trim control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilising the front stage while providing a well-balanced enhanced bass sound.
 
OSD with Colour Icons
The YHT-1840 features Yamaha’s latest on-screen display, which provides colour icons for quick identification. Menus can be viewed in English, German, French, Spanish, Russian Italian, Japanese or Chinese. In addition, menus can be overlaid over the image.
 
Traditional Design Enhances Any Room
The surround and center models have the traditional look of Yamaha speakers. Their clean design matches their high sound quality, and they can be placed in any convenient location.
 
ECO mode Lowers Power Consumption by 20%*
Yamaha’s new ECO mode reduces power consumption by about 20%. It can be set from the top of the GUI menu.
*Compared to power consumption when ECO mode is off (Yamaha measurement).
 
Selectable Auto Power Standby
Auto Power Standby lets you save energy by selecting to turn off the power after 20 minutes, 2, 4, 8 or 12 hours.
