A hero of home cinema and multi-room flexibility, the Onkyo TXRZ730 makes powerful heart to your whole AV system.

Meets the highest standards in cinema sound - THX Certification Select

THX Certification Select means that the TX-RZ730 meets the tough standards set by THX for high-volume, low-distortion sound. Only given to the finest AV receivers, the TXRZ730’s cinema sound won’t disappoint.

Dynamic and detailed sound
Featuring DAA (Dynamic Audio Amplification), the TX-RZ730 delivers a stunning frequency response all the way from 5 – 100,000 Hz. Combined with the High Current power supply and extra-large, customised capacitors, it means the TX-RZ730 produces a thrilling sound that keeps you pinned to your seat when the action gets intense. With high quality, low noise components and a discrete output, subtle details are also clearly presented.

Top quality DAC for Hi-Res Audio
At the heart of the Onkyo's digital processing is a top quality AK4458 32 bit/384kHz DAC (Digital to Analogue Convertor). This not only provides a transparent and lifelike sound but also facilitates the playback of High Resolution audio formats. The TXRZ730 is compatible with a wide range of HD audio formats, including DSD 5.6 MHz and FLAC 192kHz-24-bit for exceptional sound quality.

Dolby Atmos and DTS:X for three-dimensional sound
Dolby Atmos uses ceiling or upwards firing speakers to produce a multi-dimensional, immersive sound that's a match for the finest cinemas. DTS:X literally pushes the boundaries of what you can expect from home cinema. It renders images in three dimensions that conventional processing can't match. It also easily adapts with your existing speaker configuration.

Supports HDR10, Dolby Vision, HLG and BT.2020 standards – perfect for UHD entertainment
The Onkyo TXRZ730 is the perfect partner for your HDR-equipped TV and video source. It supports HDR10, Dolby Vision, BT.2020 and HDCP 2.2, which means you can play UHD Blu-ray discs and stream UltraHD video in the highest quality. The HDMI sockets allow 4K pass-through, for hassle free switching and viewing without the receiver needing to be powered up.

Powered sound in up to three zones
With a 5.2 channel cinema system in play, you can use the spare channels to add two additional powered zones. Zone 2 and Zone 3 can either be synced with the main signal for ‘party’ sound or play from separate sources – giving the TXRZ730 true multi-room appeal. Passive outputs for Zone 2 and 3 are also available should you already have amplification or active speakers.

Equipped to play the music streaming services you love
Compatible with Amazon Music, Spotify (Premium account required for full features), Deezer and Tidal, the TX-RZ730 covers all the major players. For Internet radio, the TuneIn service gives you access to thousands of radio stations from around the world. You also get a wide range of systems to stream your music. Choose from Wi-Fi over the network, Apple AirPlay or Bluetooth for the widest range of wireless music streaming options.

Chromecast with Google Assistant
Chromecast lets you stream music, podcasts and audio apps, including Google Play, at the touch of a button. Alternatively, use Google Assistant and this Onkyo AV receiver becomes part of your voice controlled smart home.

DTS Play-Fi
DTS Play-Fi is a premium, wireless control system that brings everything under one 'roof'. Download the free app and you'll not only have access to Internet radio but also popular music apps such as Spotify, Tidal, Deezer and Napster. As well as bringing all your streaming sources together, Play-Fi offers the potential for full multi-room music. Simply add other PlayFi compatible sources and you'll quickly be able to build up a comprehensive music system around your home - all under the control of a single app.

Or try new FlareConnect
For seamless multi-room compatibility, the TXRZ730 also features FlareConnect. FlareConnect works with compatible Onkyo and Pioneer controller apps and lets you access your music from stored devices (such as NAS drives) or streaming services such as Spotify, Tidal, Deezer and TuneIn. From here you can send the music to all FlareConnect compatible Onkyo and Pioneer products, giving you effortless multi-room music around your home.

All this, plus it will still play your vinyl
It’s not just the latest wireless sources that the Onkyo has covered, it can handle hi-fi sources, too. Six analogue line inputs, a front-mounted 3.5mm input and three digital connections are ample for the most home entertainment systems. You can even plug in your turntable, thanks to the dedicated phono (MM) input.

Take your home cinema to a higher level, with the THX Certified Onkyo TXRZ730.

Rated 5 out of 5 by from Very open sound If you are looking for a open sound I can recommend this model. It has a much more forward sound Certainly in the mid area. I’ve had a few a/vs in my time and this a/v highlights more of the recording.

Rated 5 out of 5 by from Sounds much better than the last amp that we had Purchased this from James at the Edinburgh store installed it before Christmas. fantastic

Rated 5 out of 5 by from An excellent upgrade with great sound quality I’ve had the onkyo amp a couple of weeks now and have had the time to make comparisons to the out going amp. Firstly the sound quality over my old amp (which was no slouch!) is considerable, it lights up my speakers rather than just dribbling sound. The bass is fed in at all the times with a much more controlled punch and the Atmos speakers I added sound fantastic! Overall a great buy at a good price, Sam from Newcastle pulled it of again.

Rated 5 out of 5 by from Great sound I bought an Onkyo amplifier to boost my tv sound and enjoying every minute.

Rated 5 out of 5 by from Quality amp Purchased this amp over Xmas to upgrade another Onkyo amp I had for 8 years , straight out of the box connected everything to it , switched it on and boom just pure quality , it does everything one could ask for , having a projector on the 2nd hdmi is a breeze to use , simple to switch over when needed and all 4K ...more than enough punch from the original keff “eggs” , tweak the crossover and just pure quality sound , I added the extra 4 speakers into the ceiling and now Dolby Atmos ... it just gets better .

Rated 5 out of 5 by from Great Sound True Cinema sound in your own Home. I bought this to upgrade from My Denon AVR-X2300W To a Four Speaker Atmos System well worth the Money as the sound is Great even in a 5.1 System with Atmos Speakers. Thanks to the Guys in Belfast for the help with early issue with the sound nothing to do with the AV.

Rated 5 out of 5 by from User friendly settings, great sounds I recently bought this to replace my Pioneer Sclx59. Great sounds, THX certified gives more options on cinema sound experience! Highly recommended.

Rated 5 out of 5 by from Jam packed with features totally future proof Got the TXRZ730 Lets look at what this behemoth can do visually it is compatible with Supports HDR10 ( High Dynamic Range in all of its beauty) a must have , Dolby Vision (which is like HDR but it is frame by frame encoded picture for the perfect cinema experience), I cant hype this up enough, at first I was underwhelmed with what seemed like subtle differences to the already beautiful HDR, Then I watched a full encoded Dolby vision presentation and I was blown away with the attention to detail, things like clouds and shots with sunrays had a whole new lease of life with respect to detail an colour palate along with just small details you never even knew existed and wouldn't be apparent in HDR , HLG which is reserved for very few 4K TV broadcast The good news is that with live 4K broadcasts now gaining momentum, it's becoming imperative new TV sets support the technology and BT.2020 standards – perfect for UHDTV entertainment and HDCP 2.2 for playing ultra 4k Blu ray disk. As you can see this beast has everything you could possibly need at more. The most amazing thing about this AVR in my opinion if the freedom to choose your speaker set up and the inclusion of Dolby Atmos speakers which for full immersion, What they do allow you to hear sounds that are above you, rain or helicopters for example, it really makes you feel like you are in the action and are a must for any audio/ videophile, must have experiance. On the sound front it has more ways to configure your your speakers than I even knew existed, I have mine set to 5.2.1 Which takes advantage of the Atmos upfiring speakers for full immersion although you can also upgrade to also 5.4.1 and even 7.4.1 if you have the space., to most these will just be numbers they mean 5 traditional surround speakers followed by either 2 or 4 up firing atmos speakers with the 1 meaning your subwoofer, It may sound confusing but trust me setting it up is a breeze. there are other configurations available but these are the ones that I know about, as far as the onkyo manual states you One of the best audio features is the fact that you can add two extra sounds zones for other rooms which is a very handy feature The same source can be played back in the main room and ZONE 2 or 3 simultaneously. Also, different sources can be played back in all rooms. the system supports Sonos and chrome cast, my only gripe being that chromecast us music only, no video :( features FlareConnect. FlareConnect works with compatible Onkyo controller apps and lets you access your music from stored devices or streaming services such as Spotify, Tidal, Deezer and TuneIn. From here you can send the music to all FlareConnect compatible Onkyo products, giving you effortless multi-room music around your home, fantastic if youve got the lads round for a party and have a difference in musical taste, All in all this receiver has it all and it is VERY easy to set up as long as you follow the instructions Acureflex isn't perfect although I recommend running it, then manually changing the frequency of your speakers to manufacturers guidelines also check the distances and correct them after that you should be ready to go. As I mentioned in the title it has became future proof, as of the last firmware update Onkyo have added to the unit added support for eARC suppport and DTS NEURAL X , which is massive news ( explanation condensed The main benefit of eARC is a big boost in bandwidth and speed. This allows you to send higher-quality audio from your TV to a soundbar or AV receiver.There’s scope for eARC to deliver up to 32 channels of audio, including eight-channel, 24bit/192kHz uncompressed data streams at speeds of up to 38Mbps what that means for you is higher quality audio when fullly available. with compatible TV. I have owned it for over 2 weeks and it is the joy of my life I couldn't recommend it enough. I have tried to cover all of the features I have so far used, i'm sure there is still a plethora secrets I haven't uncovered yet. Really though stop reading and just buy it already. you wont be sorry. Shaun. ONE HAPPY TECH HEAD
