This is how I have configured and calibrated the home audio system to optimize its sound quality

When we usually get a last batch television, those that we have come to call smart TV, we hope to find a high image quality and above all have access to all kinds of applications that turn the television into the multimedia center of the home. UHD, HDR, operating system … but there is one factor that we always overlook.

We refer to sound, perhaps the aspect in which current televisions tend to falter the most. The reduced dimensions, more and more stylized, make having quality and powerful speakers a chimera. We have options how to get a sound bar, but can it be improved? Yes, and the “trick” is to buy a home theater system. That is what in my case I did to improve the sound at home and these are the steps I took to configure it.

Choosing the components

Delimited by space problems, in my case I have opted for a Marantz NR1608 and a 5.1 DX 2 Wharfedale set with these steps to follow, both for the speakers and to configure the A / V receiver. For the first few little to tell, well I have taken advantage of the installation I had at home with the wiring behind the walls.

The only difference is that I got hold of four adjustable and adjustable supports to be able to search for better acoustics. It is the limit that I had and at the same time the advantage of having the installation done. I could not opt ​​for a 7.1 although I did not need it either.


To connect with the A / V receiver I have used red and white RCA connections, but instead of terminating in a plug, it made use of the copper wires themselves to connect both the speakers and the A / V receiver.

I have connected the TV through the connector HDMI ARC so that with a single HDMI connection we can send the sound from our television to the Home Cinema, audio equipment, sound bar or how in this case, to the A / V receiver. And although it offers the option to perform pairing by optical digital connection or TOSLINK, I have chosen to use this connectivity to get the sound from the Xbox One X.

Placing the speakers

The time has come to position the speakers correctly and it is that we must not forget that a large part of the quality of a home theater system is motivated by a correct placement of the components that make it up. In my case I already had the predefined location, but if it is not your case, these steps can help you determine the best place for each speaker:

First we place the center speaker, which is preferable to place it directly above or below the device of the television or monitor. I only had one possible location and that’s the one I had to take advantage of.

The next step is to place the front left and right speakers. These must have a separation between them that equates to the same distance that exists between the center speaker and the viewing position that we are usually going to have. Ideally, you should direct the front speakers so that they are at ear level in the listening position.

In third place we will place the surround sound speakers, which should be placed on the side walls of the room slightly behind the listening position and always facing the listener. In my case, it was not possible, so I have them placed on the back wall, behind the listening position.

To finish touch find the place of the _subwoofer_ and in my case, due to the generous size it offers, I have decided to place it near a corner of the cabinet that the television occupies.

Once all the speakers were positioned correctly, the next step was to connect them to the A / V receiver and perform the calibration process. It’s not just about setting your speakers to the correct channel.

A / V receiver calibration


In the case of the Marantz 1608 the calibration process has been quite curious and to carry it out I have had to perform various steps, the first making use of an accessory that shaped like a microphone and a cardboard tower, came with the device itself.

Copy Settings

By means of different pieces, I assembled the tower (it reminded me of the Eiffel Tower) and at the top the microphone that went connected to the front input of the A / V receiver (it’s the SETUP MIC jack). The corresponding menu will then appear on the TV screen, the steps of which I followed step by step.

Configuration is based on system usage Audyssey, an acoustic correction method designed to make equipment calibration and integration into the room as easy as possible. It is responsible for detecting and minimizing acoustic problems to achieve optimum sound quality. If you want more information to configure the equipment, you can download at iOS Y Android the app Audyssey MultEQ, but yes, it has a price of 21.99 euros in the App Store and 19.99 euros in Google Play.

In the process, the system asks how many speakers we are going to configure and we mark one or the other according to our preferences. In the successive steps, the team will ask us to place the microphone in different positions, depending on the speaker that emits sound at all times.

Configuration 2 Copy

For the five speakers, we are changing the position of the microphone in a silent environment so that it captures the sound emitted by the speakers and adapts it to the environment. The objective of all these tests is that depending on the audio characteristics of the room and the hearing capacity of the people, achieve that the sound can be heard even at low volume.

Once the process is finished, It only remains to find the right content to check if we have placed them correctly. In fact, we have seen in some articles Five movie scenes to put your rear speakers to the test or even movies that squeeze your home theater system. As a general rule, we must ignore the content broadcast on television networks.
