Doe you get sound in from the headphones? If so, then the issue might be the volume fader for that specific channel.

If not, then the issue might be the input connections or input pc board the connections are soldered on to.

The fader can be self replaced, although complete disassembly of your unit is required. Not a hard task, but there are alot of jumper cables, and you have to be careful when putting her back together.

If it's the latter, then I would suggest taking it to a service center for repair.

My Technic 1200's are only playing out of one speaker at a time.


Clearly there IS a setup issue. Take serrato out of the loop for the moment and the mixer. Plug each deck (one at a time) into a hifi with a MM Phono input. Are you getting stereo? If yes, you know the decks are ok. Now reset the mixer completey. All eqs and pans including volumes to 12 o clock position and volumes to 0.
Make sure you connect deck one to a red and white of one phono input channel. Do not use 1 channel from phono and 1 from line. Use both left and right of the phono chanels.
Ok, now hook up the mixer to the amp. Keep the x-fader on channel 1 and concentrate getting a good stereo signal from this one chanel. Now do the same for the other cahnnel.

This should hae helped you to get up an running, if not narrow down the problem.

One of my DJ turntables = only left side stereo sound


need to narrow it down, using 1 turn table ONLY with the mixer on channel 1 (the chanel that is working) to test reciever is working properly and sound working on both side of the speakers, this eliminate the first turn table. Next, disconnect the working turn table (1) and connect your second turn table to the same chanel and see if you getting the sound coming chanel 1 just as your first turn table did. If you getting sound coming out from turn table on ch1 than is not the turn table issue. It will be you mixer having problems. You cant solve the problems having everything connected. Testing one turn table at a time using working chanel on the mixer to see if both turn table working properly. If you use the same chanel testing both turn table and the second one does not work than it will be one of your turn table is faulty. Note: if you find and test both of your turn table is working properly than it will be your mixer. good luck and hope that help..

Problem If you swapped the two TT's would the problem stay with the connection on your mixer? At least then you/we would know wherein lies the problem. I'm betting thge low volume is because you have the phono jacked into a line level input like AUX instead of PHONO.

Typically, what you're describing is a phone source plugged into a NON-phono connection. (Tinny, low volume - classic lack of a phono preamplifier with RIAA equaliztion). A standard old-school tuntable requires a phono preamp that is labeled "PHONO". Nothing else will give it the boost and freq response correction LP's and phono cartridges produce.

Your problem #2 alludes to a channel problem with a turntable running through your mixer. This isn't rocket science. Swapping the two turntable channels around would probably change the apparent failing channel, right? Yes - Problem out at the turntable. No - problem in the mixer. You've already hinted at the source by monkeying with the tonearm wiring. You're on the right track. The tiny multi-colored wires in the cartridge shell are very thin and delicate. Their brass fittings sometimes oxidize and reseating them as you have done usually gives some relief. Kinks in the wires could cause your intermittent symptom. At the RCA end of the tonearm cables, make sure they're seated on with a twist to wipe off oxide.

Problem #3. Is it just bothering you or is there a functional problem, too?

Gemini cdt-05 hybrid grounding noise


Well, number #1 - it's a Gemini. So, you can rest assured that the craftsmanship is not the greatest. It's hit or miss with this company.

#2, if the issue you are having is a ground issue, then perhaps the internal ground wire might have come loose, or there is some sort of interference somewhere. Do you have your turntables next to anything that draws alot of power? Such as air conditioner, or a microwave, fridge, etc? Also, connecting to the same power outlet with something that draws alot of electricity might have the same effect. Try a different power outlet. One that is not being used if possible. If you use a power strip or extension cord, try a new one.

There could be many issues which cause feedback.. the main thing is to determine what is NOT causing the problem. So, you know it's NOT your mixer. Great. Now, move on to the next step. Check your cartridges also. Try swapping them out, see if the problem follows. Many times the tonearms aren't grounded properly. There are 5 wires coming out from the tonearm - L+, L-, R+, R- and GROUND. If the ground came off during transport, or movement, this might be your problem.

Good luck!

Vestax PMC 05 PRO MIXER master output is not working


More than likely the output PCB might be faulty, or the signal amp might be damaged. In either case, not an easy fix. As for service in the UK, try HARD TO FIND RECORDS - they have a pretty good service dept.

Disc Jumping


I used to have the same problem: the rubber feet of the players are too stiff. It is indeed vibration that causes the problem. Btw: after a couple hours in a club, you are usually playing much louder than at home, with more low-end punch.

I haven't had a single problem AFTER systematically setting the players on foam. This is similar to the tennis balls trick for regular turntables, except that here you need something a softer suspension as the players are very light. Shipping foam is good; camping foam mattress works also.

Low volume on both sides


Make sure you connected the turntable to the PHONO INPUT of your Vestax Mixer. If so, then the problem might be with your mixer output, or your sound system. You will need to test each unit individually to determine what the issue might be.

Pitch control center moved


Hello, Mr. Dixon.
I had the same problem and i decided it whit this procedure:

1. Restoring Factory Default Settings



2. Set the PITCH Slider to the center ( 0 ) position.

3. With the CDX-05 in the start mode displaying “no Disk” hold down EJECT and TIME/ENTER and press FILTER. The TEMP display in the LCD reads 0.0 and the procedure is complete.

Good luck!
