The Sound Technicals


Before we get into the juicy stuff for this Denon X4500H review, let’s go over the sound hardware capability:

  • 11.2 Capable (with a 2-channel amplifier added, 9.2 without)
  • 125 watts per channel
  • 8 ohms
  • THD 0.05%
  • 20 Hz ~ 20 kHz

11.2 capable means it can be used for just about any speaker configuration. You can use it to power anything from 2.0 to 7.2.4.

In this case, out of the box, it is possible to use up to 9.2, 7.2.2 or 5.2.4.

To learn why they went from 7.1 to 7.2, click here.

For more information on 7.2.2 and 7.2.4, click here.

Watts is the measurement of power used by an electrical component. When it comes to speakers, watts translate to the ability to handle higher volumes.

In this case, each passive speaker channel (powered by the receiver, not a built-in amplifier, like a subwoofer) can receive up to 125 watts to a maximum of 9 passive speakers.

This gives you a total power of 1,125 watts plus the power of your subwoofer. (If using a separate 2-channel amplifier to allow for 11.2, 9.2.2 or 7.2.4, also at 125 watts per channel, total power increases to 1,375 watts plus subwoofer)

Ohms are the measurement value for the resistance of a speaker. It isn’t incredibly important in this case, as most home speakers are 8 ohms. Basically, higher ohms of resistance, more required power for the same sound volume. Fewer ohms means you can play your content louder for the power you have.

THD stands for Total Harmonic Distortion, which exists in all electrical representations of sound. The lower the THD value, the clearer the sound is, and the closer it gets to being exactly as recorded. 0.05% is a very negligible and acceptable amount of distortion for a home AV receiver.

The human hearing range is 20 Hz to 20 kHz, so, as you can see, this receiver allows for every frequency you will be able to hear.

The Fun Stuff – Compatible Technology


3D Sound

This includes Dolby Atmos, DTS:X, DTS Virtual:X, and Auro-3D.

For information on Dolby Atmos, click here.

DTS:X is Digital Theater Systems’ response to Dolby Atmos. It uses “height” or “elevation” channels to add vertical sound to your already existing lateral surround sound. DTS Virtual:X imitates this technology without having physical height speakers, much like virtual surround on television or soundbar.

Auro-3D is a lesser-known alternative, but it never hurts to have compatibility for everything.

The Latest Video Technology

You can send video signals over HDMI that include:

  • 3D
  • 4K upscaling
  • HDR
  • Dolby Vision
  • HLG
  • IMAX Enhanced

While 3D has been phased out with the advent of 4K televisions, and subsequently curved displays, this receiver still allows for it, in case you still have a 3D TV.

The X4500H includes 4K upscaling, which means all of your 1080p DVDs will look better on that new 4K TV. It doesn’t give you true 4K clarity, but it is much better than 1080p alone.

If you don’t have a 4K TV yet, read our review of our favourite three mid-class 4K TVs by clicking here.

HDR is short for High Dynamic Range, which incredibly enhances the contrast of images on the screen, and works seamlessly with WCG or wide colour gamut, giving much more vivid, life-like colours. For more information on HDR and how it works, click here.

Dolby Vision takes HDR and adds even more to it, in true Dolby style. Where HDR gives great contrast in 10-bit colour depth, Dolby Vision gives you a minimum of 12-bit, for incredible colour and contrast handling.

HLG, or Hybrid Log Gamma, is the product of broadcasters BBC in the UK, working alongside Japanese NHK. It simplifies how television stations broadcast. It takes SD and HD signals and combine them, and makes it so your TV can play it, whether you have an HDTV or not.

Lastly, we reach IMAX Enhanced. What do you think when you hear the word IMAX?


IMAX was completely different because the film is recorded and played horizontally, not vertically. This gives the ability to have an image wider than the physical film that it is recorded on. IMAX Enhanced gives you the absolute best quality possible (combining IMAX quality images with DTS sound) when playing IMAX content.

What Can I Connect?


Now that you know what your new X4500H will do for you, you need to know what you can connect to it.


The X4500H has an amazing 8 HDMI inputs and 3 HDMI outputs for connecting all of your devices (Blu-Ray player, cable box, PlayStation, Xbox, etc) and up to three TVs or monitors.


Included in these 8 inputs is eARC, or Enhanced Audio Return Channel, which, to enjoy the full benefit will require HDMI 2.1 or higher, which includes an Ethernet connection in the same cable.

The very first benefit of eARC (or ARC beforehand), is that you no longer need to plug in an expensive optical cable to enjoy the digital sound from your devices. The digital sound signals are carried over the HDMI cable, along with UHD video signals. eARC is capable of passing the information required to take advantage of the incredible capabilities of this receiver.

eARC can be used to send Dolby Atmos, DTS:X and Aero-3D signals from your devices to your X4500H receiver.

For our favourite HDMI cable, click here. This cable will remain relevant well through 8K and works well for eARC and Dolby Vision.

Simply plug your HDMI 2.1 cable into the ARC or eARC HDMI in on your TV, and plug the other end into the eARC out on your receiver. Then, just make sure that if your connected device has eARC, that you are using that output to connect to the receiver. Done!

There are cases where you may need to activate eARC in the TV settings, which may include turning off the built-in TV speakers.


After all of your wired devices and TVs are connected, it’s time to go wireless with WiFi and Bluetooth connectivity. Update your receiver with ease, and connect to your phone to play music.

This receiver is compatible with Amazon Alexa and Apple AirPlay 2, which makes it possible to connect to any wireless device in your home.

There is also included ihiji Invision and Domotz Pro capability available over WiFi. These are both remote management companies, meaning you can turn music on at different times of day while you are on vacation in another country.

Setting it Up – The Apps



Denon now has their own line of products compatible with an app that they named HEOS. They are Alexa compatible. For our HEOS speaker choice, click here.

The HEOS app can control your compatible wireless speakers and receivers in your entire home. You can play classical in the master bedroom, and metal in the living room if you want.

As an added bonus, it works seamlessly with popular music services like:

  • Spotify Connect
  • Pandora
  • SiriusXM
  • Tidal
  • Deezer
  • Napster
  • and more!

Audyssey Audio Optimization

After everything is hooked up and connected, Denon has one more bonus wrapped up in this wonderful receiver.

Audyssey MultEQ XT32 system built in will measure your room, and adjust all the settings automatically. Then, you can go into the app, and if something isn’t to your liking in one of your rooms, you can change all the settings manually.

Now that you have seen all the glorious benefits of this receiver, and the simplicity of using it, it’s time to buy it!
