 (Entry last updated on January 19th, 2005)

It might not have anything to do with your player. Maybe it's your MP3s.

Most MP3 encoders will roll off very high frequencies with a lowpass filter as part of the encoding process. This feature allows them to devote more "encoding bits" to the frequencies that can be heard and reproduced clearly. Most people can't hear frequencies that high, or don't own playback equipment that will reproduce those frequencies.

Some encoders have option settings that will let you encode the high frequencies. Please see the MP3 creation section of the FAQ for more information.

If you're noticing a difference in frequency response between a CD player and the car player, keep in mind that the CD player is going through different DAC and playback circuitry. Most consumer CD players have their output curve "tweaked" a little bit to make them sound better out-of-the-box. The car player doesn't have a tweaked EQ curve, it's ruler-flat by default. So to make the car player sound like a CD player, you will need to alter its default EQ.

Also, make sure that you've got playback equipment that is up to the task of playing very high frequencies. Most consumer speakers start rolling off around 16-18k. Just because a manufacturer lists a frequency response up to 22k, it doesn't mean it's flat response to 22k. Usually there is a significant amount of rolloff at the ends of the spectrum.

Now, with all of that said, some early models of Mk2 (not 2a) players were fitted with EMC capacitors that tended to reduce the extreme high frequencies of the front car outputs and the home outputs (but not the rear car outputs). These capacitors were meant to reduce noise, but it was later discovered that they were not needed, and they were removed from subsequent board revisions.

There is also a report that some owners have experienced a reduction in car installation noise after removing these capacitors. This is a bit strange, since the original purpose of the capacitors was for noise filtering. But if you've got installation noise that you can't seem to get rid of, it might be worth the effort to remove these and see if it helps. It just so happens that the reports came from BMW owners, but that may or may not mean anything significant.

To check to see whether your player is affected, first make sure it is a Mk2 player, not a Mk2a. The 2a's have the correct value of capacitor already installed, so this problem will only occur on Mk2 units.

Then, following the instructions in the Drive Upgrade Guide, carefully remove the disk drive tray assembly.

Viewing from the front of the player, unplug the left-hand wiring loom in the rear of the player which hides the home output plugs. With this wiring loom unplugged, you should be able to see the capacitors as illustrated here:

(Note that on later model Mk2 units, the capacitors will be missing from these locations, there will just be empty pads there. If that's the case, you don't need to do anything because your player is not affected.)

If desired, you may remove the main motherboard, carefully following these instructions, and de-solder these capacitors. Do not bridge them, remove them completely so that there is no longer a connection at those locations. Use caution not to interfere with the resistor that's near one of the capacitors (not shown, it's behind the wiring connector).

Do not attempt to do any soldering on the player unless you have experience with soldering delicate surface-mount devices. There is a real possibility that you could permanently ruin the unit if you are clumsy, if you use too much heat, or any number of other mistakes. You're better off contacting support and having them do it for you.

Don't do this procedure "just because". Before you do this, please make sure that you're definitely experiencing a problem with noise or with the player's high frequency output, and not just running into the limitations of your MP3s, your hearing range, or your amps and speakers. If you're not extremely careful, you could cause damage to the player during this procedure, and it's not worth the risk unless you're pretty sure you're going to be able to hear a difference when you're done with it.
