Question about Crown CE1000 2-Channel Amplifier

1 Answer

Channel 1 static and lack of performance

Channel 1 is low on volume and when i turn the gain up and down its gets staticky(sp) and inconsistant. It gets the quietest at about half way up. I know its just channel 1 because i switched the speakers and it changed with the switch. It seems that sometimes it works fine and other times it does this. It is a little dirty from and outdoor event but it had been working fine since til just recently. I also tried pushing the reset button but it didn't seem to do anything at all.

The potentiometer (volume control) is probably dirty. Open the amp and find the "pot" connected to that volume control. You should be able to see small opennings where you can spray electrical contact cleaner inside. Give the knob a few turns and try it out. If it gets better but not perfect, repeat. If several attempts don't eleminate the problem, the pot will most likely need to be replaced. Contact cleaner can be found at any electrical supply store such as Radio Shack. Be sure to use one that says no or zero residue. I use a product called Electrosolve.

When setting up xr8600 is it best to start mains and monitors master at 0DB?


1. Turn the main and monitor volumes all the way down (off). Plug a cd player into channel 9/10 and play a track of music of your liking. With the main/monitor volumes still off, adjust the gain on 9/10 until the clip light turns on, then back it down until the clip light just turns off. Put the channel volume at 12 o' clock.
2. With the music still playing, turn up the mains to the desired listening level first, and then adjust the graphic eq until the music sounds good in the room. Remember or mark the position of the volume control. Do not use the channel eq on 9/10 for music that has been mastered properly, leave the eq flat. Once this step is completed then you have now set the main eq.
3. Repeat the same for monitors. Turn off the main volume and then bring up the monitor main volume to the desired level first, then set eq. Now your monitor eq is set properly. Remember or mark the position of the monitor volume.
4. Set up microphone - plug a mic into channel 1 with volume all the way down. Speak or sing into the microphone and adjust the GAIN until you see the clip light, then back down a litttle on the gain. Put the monitor and main volumes back up to the mark from step 2. Now adjust the volume and monitor send on the mic channel to the desired loudness first before adjusting the mic channel eq. Use subtractive eq method to minimize distortion and feedback. ...i.e. if the mic is bassy then turn down the lows, do not ADD highs. If the mic needs bass, turn down the highs.

My clean sound is very dirty. it sounds like the crunch channel is on and turned down.


I'm not sure which amp you're playing thru. but generally the settings you want for a clean sound. check your drive (or Gain ) knob. You want it about half way.and your Channel volume, half way. those are good starts. then let your master volume do the rest. Also, make sure, if you have active pick-ups on your guitar. check the batteries. if they're low, it can cause distortion. if this doesn't resolve, then its internal. could be anything at that point.

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest


1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

How do I turn down the volume of the ringer? LCD 12B phone system.


hi, with the handset down dial Transfer 114 then either use the volume key to scroll up and down the range or you can use the number buttons from 1 to 8 ( 1 being the quietest, 8 being the loudest). I've posted a video for you off http://www.abbeytelecom.com refering to handset volume.

Sound output is heavily distorted.


Check following things:

1. The master volume control on the SR16 is at least half way up. Turn down the amp as needed. Running very low output of the SR16 and high amp gain is sure to get distortion.

2. Check power adapter is the original and is producing correct voltage.

3. Check that audio cable is high quality instrument cable and not consumer or speaker cable.

Low ohms light flashes and bass distorts at high volume


Sounds like you need to invest in a capacitor. Those are used when subs receive a bass spike. You just a need a 1 Farat Capacitor (1,000 watts) ran between the head unit and the amplfiier to fix your issue. Also, try reducing the volume gain to half gain and low pass frequency to half gain; this will increase your clarity and make your amp less hot. This may fix it without a capacitor. Also find out what amprage your alternator is. Your alternator may not be designed to run the amplifier. Most alternators are 200 amps now if they are gold plated.

Hope this helps

Ive got no power to the amp trough the rem wire unless i connect.


You need a bigger amp and make sure its a two channel. Four and five channel amps are for mids and highs. If you want real bass get a two channel. If you dont want to buy a bigger amp, Go get a capacitor. It acts like a battery charge storage for when your sub needs to hit those real low notes. It takes a lot of power. Also if you get a capacitor your altinater that charges your battery will not have to work so hard keeping your battery charged, Thus not wearing out your altinater and not having to replace it so soon because it will happen.

Another quick fix is turning your gain down. I turn my gain up half way, maybe a little past half way. You might not get the bass hitting as hard but at least it wont shut off on you.

Low record level for guitar


first of all you want to have your guitar amp at a decent volume but too loud, just enough to be able to get a good signal. when you have done this turn up the gain on your mic channel so that your VU meter (level meter) on the recording software shows a reading of about half way up the meter. If you can not achieve this with the soundcard alone increase the gain on your channel in the software.

This sound guarantee a good signal but as with most recordings you will still have to boost the signal without it peaking. to do this use a compressor or a limiter and turn the gain up. if you use these dynamic effects correctly you will achieve the guitar level you want.
