Dell S3225QC 3D Spatial Audio User Self-Test Instructions

Affected Products:

• Dell 32 Plus 4K QD-OLED Monitor S3225QC

There are three self-tests on the Dell S3225QC 3D Spatial Audio:

• Stereo Audio Content Test
• Multichannel Audio Content Test
• End-to-End Adaptive (Audio) Test

Note: To perform the below audio tests, the audio test file needs be download from Drivers & Downloads on the S3225QC product page on Dell Support. Click Download next to Dell S3225QC 3D Spatial Audio Test Files.

Stereo Audio Content Test:

Users must download the audio test file (Left-Center-Right.wav) from the support page to test. This test file is a 2 channel, 48 kHz, 24-bit wav file for maximum operating system compatibility.

Instructions to perform Stereo Audio Content Test:

1. Sit in the center over arms-length from the screen.
2. Configure S3225QC in Windows as a Stereo device.
    
   Note: For Mac User, reference the Apple support site to configure the speakers (https://support.apple.com/guide/audio-midi-setup/set-up-audio-devices-ams59f301fda/mac ).
3. Play the Left-Center-Right.wav to begin the test.
4. Test track contains a notification tone first in the left channel, then in both left and right channels, then in the right channel only.
5. The audible effect should be a source positioned on the left, in the middle, then on the right.
   
6. When 3D spatial audio is ON, the sounds should appear from beyond the edge of the monitor, sounding in symmetrical horizontal positions at all the same volume.
7. When 3D Spatial Audio is OFF:
   • The left sound should play from the left two speakers.
   • The center sound should play from all speakers except the middle.
   • The right sound should play from the right two speakers.

Multichannel Audio Content Test

1. Users must download the audio test file (multi-channel-announce-v2.wav) from the support page to test. This test file is an 8 channel, 48 kHz, 24-bit wav file for maximum Operating System compatibility
2. Sit in the center, over arms-length from the screen.
3. Configure S3225QC in Windows as a 7.1 Surround device.
    
   Note: For Mac User, reference the Apple support site to configure the speakers (https://support.apple.com/guide/audio-midi-setup/set-up-audio-devices-ams59f301fda/mac ).
4. User to play multi-channel-announce-v2.wav to begin the test.

   • Center (C)
   • Right (R)
   • Side Surround Left (SL)
   • Side Surround Right (SR)

End-to-End Adaptive (Audio) Test

This is a complete test of both the user-position sensor and the position-adaptive part of the 3D spatial audio algorithm. This test is to find if the adaptive audio is working.

Users can download the audio test file (drum-loop-mono-v2.wav) from the support page to test. Users must select 3D spatial audio mode in the On-Screen Display (OSD) and play the mono drum loop audio file to begin the test.

Test Procedure for End-to-End Adaptive (Audio) Test:

1. Move 20 cm (7.8 inches) to the left. The drums should move so that they are playing from straight in front of you.
2. Cover the sensor with your hand.
3. Keep the sensor covered and move so you are 20 cm (7.8 inches) to the right side.
4. Uncover the sensor. The computer should react within one second so that the sound appears from in front of you again.
