Wireless Sound Speakers

With modern portable technology where every gizmo is going wireless, brands like Yamaha have to adapt faster or risk being left behind.

No wonder in the RX product range, they have installed technology in both music systems with the capability of wireless connection.

You can just connect your wireless speakers to the music system via Bluetooth, which is a colossal step up from what we know from the previous times, whereby everything had to be connected with a cable.

Directions to connect speakers to the music system

According to Yamaha, when you combine the AV receiver with any of either the MusicCast 50 or MusicCast 20 wireless streaming speakers, you can bet that enjoying the convenience of creating a home theater with wireless rear speakers in a 5.1-channel system is pretty much guaranteed!. 

What’s more, you get a stunningly realistic sound with a clean, clutter-free setup. Quickly turn your current living room into an entertainment environment where you can fully enjoy movies, music, and games.

HDMI Support 4k Ultra HD

As times change, so does technology, and recently, the HDMI standards have also advanced, but Yamaha has made sure to advance with the time as both music systems are compatible with modern HDMI standards.

The AV receivers deliver transmission of 4k video at 60 frames /second pass through.

It also supports high dynamic range (HDR)Video, including Dolby Vision and Hybrid Log-Gamma, which provides incredible contrast, smooth tone, and vibrant, bright colors.

All these features give you full, high-definition enjoyment with an exceptionally realistic and natural picture quality.

Wifi and Bluetooth and Airplay 2 are all compatible.

Music lovers will love this; the built-in wifi allows you to connect to a wireless router, totally making system connections very simple to connect so you can stream music as you wish. 

If Bluetooth connectivity doesn’t excite you, you will be glad to know that with Bluetooth connectivity enabled, you will effortlessly stream into your receiver or out from the receiver to another Bluetooth device such as a pair of headphones. Also, Use AirPlay 2 to stream music from iOS devices.


YPAO – R.S.C. (Reflected Sound Control) Sound Optimization

Do not let the jargon overwhelm you! As room setting differs from one house to another, you need technology that is able to analyze the room’s acoustics and measures various speaker characteristics. This way, you can then calibrates your audio listening parameters so you and your audience can achieve optimum sound. 

While Yamaha RX V685 uses YPAO -RSC technology which employs Reflected Sound Control, there are also other varying technologies widely used to correct early reflections for those who need quality studio sound. 

It also provides DSP Effect Normalization, which varies the Cinema DSP parameters according to the reflected sounds.

Two HDMI Outputs

Since the RX-V685 has two HDMI outputs,this allows for a simultaneous connection to a TV and video projector. Or if you wish, you can add TV in a common area like a dining room, kitchen, bedroom, or patio to watch the same content in two different places in the house. HDMI Out 2 will carry an HDMI audio signal to the second TV to provide sound.

Zone 2

This feature, also known as Intelligent Amp Assign, allows users to enjoy stereo sound in a second room. When Zone 2 is turned on, the two surround back channels in a 7.1-channel system will be redirected to the two speakers in Zone 2, while giving the Main Zone 5.1 channels of power. 

Thanks to this feature, there’s no need to switch the speaker cables on the rear of the AV receiver.
