I bought an Infinium X1 crossfader (serial number S200900032954) as a replacement for my DDM4000 mixer (serial number S1500259167, date code 1503).

The installation instructions look straight forward, though getting the three-cable plug into the spare socket the DDM4000 has for a replacement crossfader is a bit fiddly.
However, once installed it does not work: It lights up, but moving the crossfader has no influence on the audio signal between the selected channels of the mixer.
There is one post here from about a year ago which desribes the same problem but it unfortunately received no answer.

I submitted a support ticket to Behringer three days ago but have not heard back from them.

There are many post on various online forums describing this exact problem (and also reporting that the non-functioning crossfader is getting very hot when connected "as is"). People claim that you need to cut the two outside wires of the three-wire cable and switch them around before connecting the Infinium X1 with the DDM4000.
Surely, I do not have to do a DIY soldering job to connect a genuine Behringer spare part with a Behringer mixer?!?!?!
What is the problem here? Has the socket on the DDM4000 been soldered on the wrong way around in the factory or is the plug at the end of the wire of the X1 soldered on the wrong way around?

What is the solution, please?

PS: The marketing blurb for the X1 says "Complete installation instructions and a dedicated toolkit are provided for your convenience."
The installation instruction contain a picture (see attached) which says "Possible only with DDM4000" which is difficult to interpret. I think it's meant to show that the DDM4000 has a spare socket to connect the cable, but I am open to hear other interpretations.
Also, the "dedicated toolkit" is a flathead screwdriver, when in fact all screws you need to losen and tighten for the job on the Behringer equipment are Phillips. The documentation even shows all screws and the screwdriver to be Phillips, not a single flathead as the included screwdriver.... Bizarre.
Is this whole product a bit of a cock-up?

Hallo zusammen.
Ich möchte gerne Schallplatten live während meiner Radiosendung abspielen. Angeschlossen habe ich meinen Dual DTJ301 USB an Port 11/12 am Mischpult.
Gibt es eine Möglichkeit die Schallplatten auf den Stream zu bringen, ohne das Mikrofon auf "on" zu lassen? Ich sende mit dem Streamingprogramm Sam Broadcaster Pro Version 2021.2 und Windows 7

Danke für eure Antworten

Hello all.
I would like to play records live during my radio show. I have my Dual DTJ301 USB connected to port 11/12 on the mixer.
Is there any way to get the records to stream without leaving the mic on "on"? I am streaming with the streaming program Sam Broadcaster Pro version 2021.2 and Windows 7.

Thanks for your answers

I'm trying to find info before purchase. I've been tasked with doing the music for a party, & decided to get a DJ TT with phono out to play popular music spanning 60 years from my record collection. I was going to leave it at that, but decided CD's would be good too, but don't want to invest in a DJ CD unit, and all my CD's (as well 78 rpm & audiohile LP's) are recorded to 16x44.1 or 24x48 flac files. I can only really access them through a Sony VAIO laptop running Linux Mint or a Raspberry Pi (with a DAC). It looks like the process of playback would be simplified by routing both through a mixer, and this looks like it might do the job. I can justify the purchase as part of a setup for making videos about recording & reprocessing pre-loved vinyl & shellac from prior to 1970.

So, can anybody tell me if the DJX900USB will work with a flac files &/or a laptop running linux?

I can hook the linux laptop up to a Native Instruments Audio Unit OK, and it appears to work fine for recording and replay (but the NI has no phono stage, and I'm trying to eliminate the need for a separate preamp, & make transitions smoother.

I assume the phono input on the Behringer mixer implements the RIAA equalisation curve?

I'm assuming the mixer coverts the analog signal into digital via a DAC, then outputs the digital signal to analog for line out? If so, I'd rather take the flac output direct via USB rather than using an external DAC to convert the files to analog line out on linus, then feed that into the line in on the mixer, avoiding two steps in the conversion process.

What are the specs of the internal DACs & ADCs on the Mixer?

If this unit isn't going to provide the functionality I need, is there an alternative?

Morning my name is Lebo and recently I was playing music went outside for a bit and when I came I noticed my mixer was off I tried using different power sources but it wouldn't turn back on. One thing I had noticed was it a bit hot but there was no smell of anything that might have burned. So my question is what could be the reason for this

Ive recently got a djx750 mixer I went to use for the forth time and during my set the audio in and out  has gone I get nothing out of it it still switches on but dead I can't find my recipe for it plus I got on line brand new less then 9 months old and also it gets so hot u can fry an egg on it ive never had a mixer get as hot as that dose any way I can get replaced or repaired...?
