I have Technics SL-1200 running into Pioneer DJM-450 mixer, and I am trying to set up control vinyl.
I have the turntables running into the phono inputs, and the channel switches on the mixer set to computer.
When I play a song, the sound comes out, so I know the signal routing is correct BUT...
When I go the the DVS tab in Rekordbox settings
Channel 1 (Deck 1)
a) Doesn't show the circular waveform, it only shows a flat line.
b) When I try to auto calibrate the L/R P/A Balance, an error message appears next to the start button.
c) The playback is all pitchy - moving between correct playback speed, and super slow
d) Some attempts cause the playback to be at half speed
e) Manual calibration doesn't fix any of this
Channel 2 (Deck 2) - the waveform shows correctly, but I still get the calibration error
Any ideas what is going on??

A flat line indicates that one of the inputs is not working. If you reverse the L/R and the line goes from horizontal to vertical, you know the issue is not the mixer. Things you may want to check include:
- the RCA cable
- the headshell wiring
- the cartridge
- the stylus
You'll need to fix that before addressing any other issues with the DVS as some are related.
Thanks very much for the reply.
It was the RCA cable which I replaced. There was an easy instructional video on youtube, and it basically was 4 solder points that needed to be removed and re-soldered.
Info for anyone with similar issues:
I worked out that one of the RCA cables was faulty, when I removed them one at a time from the mixer inputs while playing a record. Just the white was fine, but when I left only the red one in, there was no audio, just a buzzing noise.
Once the RCA cables were replaced, the DVS signal worked perfectly, and the calibration worked on both decks perfectly as well.
Thanks again.
