Question about Pioneer DEH-P3100 CD Player

1 Answer

Volume boosts to 30 and all buttons become useless.

Hi,

My Pioneer DEH-P3100 is malfunctioning. The volume started randomly boosting to max (30) and then all the button on the console would become useless. Now it seems permanently stuck this way and I can't do anything but connect it and have the music explode my eardrums. Can you help me?

    Same problem, however, when I pull the head unit from the car and hook ip up to a battery on my workbench, no **** problem occurs. Ground loop or surge knocking out the faceplate IC perhaps?

How do you set the clock on the Pioneer DEH-P3100 CD Player


For most older Pioneer single CD players, you can set the clock using the following steps:
  1. Press and hold the SOURCE button until the unit shuts off.
  2. Press and hold SOURCE again until the clock appears.
    *With some models you will press and hold the FUNCTION or AUDIO button instead of the SOURCE button.
  3. Press the left or right arrow to select the segment of time you wish to adjust.
  4. Press the up or down arrows to increase or decrease the numbers in the blinking segment.
  5. Once the clock is set correctly, press the SOURCE button to exit.
If you continue to have problems, contact our Product Support at 1-800-421-1404.



First push the source button until the stereo is off. Then hold the Program Function(PRG F) key(upper right corner of CD Player) down for ~2 seconds. This will take you to the Initial settings mode keep pressing the PRG F key until you get to the time setting mode. Then select the hour or minute with the left/right arrows located on the right side of the player and the up/down arrows will change the setting.

Tip

Adjusting your gain for your amplifier, or amplifiers


I contacted JBL, and Pioneer about the RCA outputs of the DEH-P5800MP. I got a question answered by JBL that you should gain your amplifier, or amplifiers at half of the Head Units volume, in which case the 5800 model has a max volume of 62. I would assume that this goes for any unit since I didn't give JBL the model or brand, which indicates that they are giving a tip on every, or most units unless specified. You can e-mail the manufacture on what unit you have just in case yours is different. I found after a good conversation with the technical support guy at Pioneer that you should turn your volume up to 25-30 (25 for your loudest CD, and gain it from there. I told him that I was an audiophile and he suggested that I could gain it at 45 for my lowest recorded CD. I have been installing and gaining systems at 3/4 volume, or if the max volume was 62 then I would gain my lowest recorded digital CD at that volume. I was amazed that JBL had an answer for probably 90% of the head units, and I have learned something new. I was under the assumption that the higher the volume the more voltage the RCA's put out allowing you to be able to have your amp gain at a lower level. From my experience of 12 years, hearing both companies say roughly the same thing it is apparent that Pioneer units with a 2 volt output should be gained at the 25-30 volume range(probably for your lowest recorded CD. I have CD's that are pure digital and bass CD's and CD's that are recorded louder (like techno music, or alternative music) If you know what you are doing, and can hear distortion, like I can, the tech said that I could gain it at 45 for the lowest recorded CD. This allows your lowest recorded CD to be played at max volume at 30-45, and your loudest CD's would be at peak volume before 30, or 45 if you choose that route. Keep in mind that less power blows speakers before more power does. That is the best advice I can give, and I will adjust my system accordingly to there recommendations. Thank you

With the vehicle on, turn OFF the radio. Next, Press the Volume and hold the VOLUME knob. You should see LANGUAGE on the display. Scroll the VOLUME knob until you see CLOCK SET.

Audio settings for pioneer DEH-P3100UB


The q1w and all that- is a way to fine tune your eq settings: the q means "frequency" the w means wide and the n means narrow. if you choose to boost your lows at 125 hz which is a low midbass the q selection you choose will focus more on the frequencies very close(narow) to that frequency. if you choose a w setting it will spread the boost to frequencies further away(wider) from the center frequency(125hz) Dink around with it and you will notice the way it contours the sound a little. The different numbers associated with the lows mids or highs are the frequencies that you want to boost when you're adjusting your sound-example if you turn up the bass and it starts distorting your speakers = go into settings 2 and change the "lows" Q to a higher frequency(change 80 hz to 125hz) and that way it wont muddy up your sound quite as bad if at all

AUX input on Pioneer DEH P31000


There is a plug on the back called an IP-BUS. You should be able to hook the ipod directly up to that with a simple homemade adapter. I built one for mine and it works fine.

Malfunction


Check none of the buttons are stuck in. Try pressing the reset button. I think it is bottom right and recessed in a hole. The unit should be on and you'll need something pointy like a pen or toothpick. If you cant find the reset button, disconnect the car battery for a minute or two. If that doen't work, then it will probably need repair.
