When it comes to heavy conversation material the Denon AVR-S540BT excels at it.

Setting Up

The device’s setup is straightforward. If you run into any problems, the on-screen setup tutorial will quickly assist you, and the color-coded speaker connection will help you solve any speaker connecting issues.

The onboard calibration process improves sound and output, which we don’t see in other entry-level AV receivers.

The Denon AVR-S540BT also has a microphone that will automatically calibrate and assign the appropriate settings once it is placed.

Auto Setup

Step 1

Install the Sound calibration microphone on a tripod in the primary listening location.

Point the microphone’s tip toward the ceiling and adjust the height to match the height of a listener’s ears in a sitting posture while installing the Sound calibration microphone.

Step 2

Set up the subwoofer as stated below if it is capable of the following modifications. When employing a direct mode subwoofer, disable the volume adjustment and crossover frequency setting and turn on direct mode.

When a subwoofer is used without a direct mode, set the following parameters:

  • Volume : 12 o’clock position
  • Crossover frequency: Maximum/Highest Frequency
  • Low pass filter: Off
  • Standby mode: Off

Step 3

Connect this unit’s SETUP MIC jack to the sound calibration microphone. When the sound calibration microphone is attached, the following should appear on the screen:

“Your AVR can automatically measure the acoustics of your room and optimize your speakers.”

Step 4

Select “Start” with the arrows on your remote, then press ENTER.

Step 5

Select “Next” with the arrows on your remote, then press ENTER.

Step 6

Select “Begin Test” with the arrows on your remote, then press ENTER.

Step 7

Remove the setup and measurement microphones from the SETUP MIC jack on the device. After “Auto Setup,” do not adjust the speaker connection or subwoofer volume. If these are altered, restart “Auto Setup” to determine the best equalization settings.

Manual Setup

Speaker Config.

You may choose whether or not speakers are present and the playback capability for low bass frequencies and speaker size from the speaker configuration menu.

And under this menu, you can tweak the following:

  • Front speaker
  • Center speaker
  • Subwoofer
  • Surround speakers


This setting is where you may adjust the distance between your listening location and the speakers. It’s critical to estimate the distance between the listening location and each speaker ahead of time.

Here, you can modify the following:

  • Unit of distance (Default: 1 ft)
  • Set the distance (0.0 ft – 60.0 ft)
  • Set Defaults (Reset tweaks to default)


In the Levels menu, you can set the loudness at the listening location to be the same when each speaker’s test tone is broadcast.

And under this menu, you can tweak these settings:

  • Test-Tone Start (output adjustment)
  • Set Defaults (Reset tweaks to default)


The lower frequency of the bass frequencies, which you can change, can be played back through each speaker under the Crossovers menu. Here, you can set the crossover frequency, which ranges from 40Hz to 250 Hz (Default: 80 Hz). 


Under the Bass setting, you can adjust the subwoofer and LFE signal range playback.

Under this menu, you can tweak the following:

  • Subwoofer Mode
  • LPF for LFE

The overall setup of the Denon AVR S540BT is actually made really easy with the Auto Setup option. For those who want to play with the settings a bit more or are a bit more experienced than the average user, you can enjoy the manual option. Either way will set you up nicely for an excellent listening experience.

Pros and Cons


  • Excellent functionality is available.
  • Customization options abound.
  • The build is sleek and attractive.
  • 4K output.
  • Great clarity in dialogue-heavy content.
  • Good Sound Quality for this Price Range
  • Wireless connectivity (Bluetooth)


  • Speaker Connection Spring Clips
  • In large rooms, they may struggle.


Finally, the gadget is a wonderful addition to your home entertainment system for the price. However, it fails to fill sound in big areas, although it is appropriate for mid-sized to smaller rooms.

This receiver doesn’t have much to say about it. The Denon AVR-S540BT offers a lot of features for the price. It’s amazing for movies and incredibly good for music in terms of audio. 

My one caution is that if you put this receiver in a large area, it will struggle to fill it with sound; nevertheless, it will shine in a small or mid-sized room.
