MP7xxx – Sound quality is bad

You audio setup is generally put together by;

• Audio source (music player, laptop, MP3 player, phone, etc
• Audio cables (between audio source and amplifier)
• Amplifier
• Speaker cables
• Speakers

Bad audio quality can be caused by each of the parts mentioned above. The key to finding out which part is causing it, is to systematically check all of them. Please follow the next steps to try and resolve the issue with having bad sound quality with a MP7xxx music device:

1. Perform an Audio test with your player (to check the player)

To do an audio test on your player (you can only do this when it is powered on) please press the left arrow from the menu. The display should now show: ‘ctrl out 1’ and Music should now start playing from the player itself. If the audio that is coming out of the player is OK (good quality), then the problem is likely with the audio cables or with your amplifier. If the quality of the audio that comes from the player is not okay, please contact our Customer Support Helpdesk. To close the audiotest please press OK twice.

2. Power cycle of both the player and the amplifier

Turn off both the music player and the amplifier. Take out the power cable of both devices for at least 30 seconds. Connect the cables back. Power both devices back on and see if the sound quality has changed.

3. Check if the (audio) cables are damaged

The cables should not show any signs of damage or wear and tear. If the cables/ connections are damaged in any way, they need to be replaced. Please contact our Customer Support Helpdesk if this is the case.

4. Check if the audio cables are connected correctly on the player

They need to be plugged in the correct audio ports (AUDIO OUT 1 and AUDIO OUT 2 ports). If the player has one zone, it only needs one audio cable connected at the back, on one of the AUDIO OUT ports (normally it should be AUDIO OUT 1). If the player has 2 zones, it should have 2 audio cables plugged into ports AUDIO OUT 1 and AUDIO OUT 2.

Try and gentle wiggle the audiocables to see if they are plugged in all the way. It sometimes needs a ‘click’ at the end to make sure they are connected well.

5. If you only have 1 zone on the player, try to move the audio cable into another audio out port (on the player)

If the player only has 1 audio zone, all the 3 AUDIO OUT ports in the back will play the same music.

Attention! Please be aware that changing the AUDIO OUT port may affect the messages playback if they are set only for the first zone. Plugging into a different AUDIO OUT PORT, in this case, must be done only for testing purposes. If you notice that the sound is better on a different out port, please contact our Customer Support Helpdesk. This might indicate that the out port is damaged.

6. Check if the audio cables are connected correctly on the amplifier

Before handling or unplugging any cables from the amplifier, make sure you first turn it off. When handling the amplifier and its cables there is a risk of electrical shock
Make sure they are plugged in correctly (try to unplug and plug them back in or wiggle them a bit). Make sure they are plugged in the correct output and that the port that they are plugged in matches the source that is chosen on the amplifier. You can try a different input on the amplifier together with also changing the audio source.

7. Check the speaker cables

Before handling or unplugging any cables from the amplifier, make sure you first turn it off. When handling the amplifier and its cables there is a risk of electrical shock
Check the speaker cables on the amplifier. See if they are connected well and / or if they are damaged.

8. Verify speakers

If the bad sound comes from only 1 speaker (and the rest of them are okay) it probably means that the speaker or cable to that speaker has a problem. If this is the case you need an audio technician to check your installation.
