Pro Tip: DVS Calibration and Setup for Serato DJ
These practices may be familiar to those who have moved to Serato DJ from using Scratch Live and are steps that we recommend each time you set up in a new environment. When using a control signal (Vinyl or CD) we are tracking two things, the playback direction and the position on the Noisemap™. With this in mind, we are aiming to achieve the tightest response and the least signal interference by tuning our rig to the surroundings.
WHY / WHEN ?
Stomping crowds and subwoofer stacks can be the catalyst for a great gig, but to get good tracking with all this, you will need to calibrate your setup. Do this at the start of each set for the tightest response and best tracking. The same story goes once you get home to your regular spot - your cats will not be as loud as the club, your speakers are probably not as big (even if they are they will impact a needle in a different way!) and the vibrations through the floor will not be as prevalent, depending on your situation ;)
As rule of thumb – calibrate EVERY time.
The devices that you do not need to calibrate are controllers, HID connections with CDJs or if you are mixing in Internal (INT) mode using MIDI.
NOISE SENSITIVITY THRESHOLD. WAT?
The noise sensitivity threshold is the limit below which the input signal will not be interpreted as a control signal. Sounds complex right? Quite simply any audio below this threshold setting it is considered background noise and is ignored by the software. This setting is necessary because a turntable stylus is very sensitive to the noise around it and will inevitably pick up background noises, mistaking them as control signal, leading to bad tracking and less control.
Setting the Noise Threshold
1) Turn the sound system up to the level that you will be playing during your performance.
2) Play a track from an audio CD or from the other deck in internal mode.
3) Place the needle on the record but keep the turntable stopped.
4) Click and hold down the Estimate button for a few seconds – Serato DJ will estimate the optimal threshold setting for the current environment. Alternatively you can try manually moving the estimate slider to the right until you notice the number in the upper-right corner of the scope view stops fluctuating (see below).
NOTE:The process for calibrating a CD player is almost exactly the same and although it does not vary as much as a turntables needle it is still important to calibrate! The only difference when calibrating a CDJ is that you need to press pause on the cd deck with the control cd in the player before hitting the estimate button.
The scope views on the setup screen in Serato DJ display the input signal as a phase diagram for each input. This green scope view gives a visual indication of the control signals input quality and how well it is tracking within Serato DJ.
Once you have set the threshold you will need to start both turntables and place the needles on the control vinyl. You want this green scope readout to cover a 2x2 grid with nice clean lines and a round shape at the minimum zoom level. Use the scope L/R balance and P/A balance controls to adjust the shape of the inner ring, you want this to be a nice clean circle. The number in the top left corner of the scope view gives the current absolute position within the control record or CD. The number in the top right corner is the current speed in RPM.
You can also view the tracking percentage in the bottom left corner, you want this to be as close to 100% as possible but obviously the quality of your turntable and needle factor into this figure so aim high!
With this knowledge in your pocket you are armed to rock a DVS set in any situation- no matter how crazy. Once you get into the habit, this practice only take a few moments while setting up and provides a good stable starting point for you to flex your skills and put on a good show.

There's also a great support guide to calibration and how to troubleshoot any issues in our support centre.
You don't need the DVS Expansion Pack for the DDJ-SZ as it is a DVS ready controller and reads control signal automatically.
Feel free to hit up firstname.lastname@example.org if you think you might have purchased it by mistake.
It's not technically possible for the DDJ-SX to run the DVS Expansion Pack. If you've only recently purchased, I would recommend talking to the retailer about a possible trade-in for the DDJ-SX2.
You can also run those CDJs to your laptop and use them in HID mode with the SXmkII :)
Nope, your Expansion Packs are linked to your account which you can access from any laptop. You do need to de-activate them on one computer before activating on the next though.
If you are having trouble with this, hit up the support team at support.serato.com and they'll be able to help you out.
What mixer are you using? The RP8000 is supported as an accessory, but won't bring Serato DJ online by itself. You need to have a supported mixer, interface, or controller to get it going.
Whether you need the DVS expansion pack or not will depend on what hardware you are using.
i'm wanting to use timecode vinyl but getting really low readings on the calibrate side
only get a slight reading of 36% when i'm fully zoomed in and noise sensitivity are full ( more )
oh and the both pa circles are on full
i know its meant to be a clean round circle with a read out of 100%
but mine is like a diagonal line with little movement
i have try'd swapping needles even got new ones and still no joy
any ideas at all
Does your scope view look similar to the 6th example in the link below?
Link > support.serato.com
If so, the left and right channels have been summed to mono. Ensure your cables are properly connected and try swapping headshells. If this fails you my need to have your turntables serviced.
I would bookmark the above link, as it can come in handy for diagnosing scope views and trying to get an understanding for what the views mean.
Let me know how you get on.
I purchased a pair of Audio Technica LP120s and a SX2 + DVS license about 2 months ago. I owned a SX for about 2 years before that but wanted to move back into using vinyl again going forwards. I had everything set up/calibrated as per your site guides and it was all performing OK - barring some flutter in the bpm readings, but that wasn't a problem, just a bit annoying.
Then about 3 weeks ago my SX2 developed a fault. It has just been repaired and I got it back earlier this week. At the same time I grabbed a single Shure M44-7 stylus to try out and see if it helped the DVS performance as I do some basic scratching when I play.
I set everything back up again today and followed the same processes as before, but I immediately noticed a marked difference in the calibration outcomes. The scope circles for each deck were much smaller (previously they were about 2x2 squares before zooming in) and the noise sensitivity changed to -72db on both decks (was around -48db before).
On deck 1 (AT stylus) if I manually adjust the sensitivity to the midpoint I get a very bad distortion, and on deck 2 (M44-7 stylus) it just cuts out the audio if I move it to the midpoint or further right.
Here's some pics of each scope view - both are fully zoomed. Without zooming the circles are really just blobs of green!
Overall the output for both decks sounded OK to my ear, so maybe none of this is a big issue - but I'd be interested to get your thoughts or advice on the changes, and if you think I'm missing something obvious in the set up or calibration?
I'd recommend you get in touch with our support team for help. They can look into what's wrong - support.serato.com
Do you have the AT-LP240 connected by USB at the time? It should be all good to use if you don't have it connected by USB.
If not connected is what you are doing and you still get this issue, I'd hit up the support team at support.serato.com so they can try figure out what's going on for you.
- Second thing:
I'm afraid to play in clubs with Serato dvs because of calibration, we are sure that if I used the instructions nothing happens bad ?, I can not experience during the evening there is' a sure way to make sure this does not happen ?
- Other question can i send back the ddjsx2 to buy the new controler? ...pioneer of course
No problem with your English, you're doing well :) You can always write in Italian if you prefer and we'll see what Google can do for us!
For your questions:
1) Sorry man, you'll have to ask Native Instruments about behaviour with Traktor
2) If you use the calibration instructions we have here support.serato.com, you should be good to go. It's important to do this in the performance environment.
3) You will need to talk to the retailer you bought the DDJ-SX2 from to see if you can return it.
I've just installed Serato Dj 1.7.8 with the Club Kit Expansion Pack. I've followed the calibration instructions and everything seems to be as it should as per the instructions above. My issue is when moving the time code record in slow increments the tracking hesitates or jumps making it hard to set accurate cue points. For example moving the record say a half inch forward slowly to set a cue point the DVS loses traction and jumps positions. This happens with the turntable platter off as well as when its on and spinning.
I am currently in Relative Mode.

I have a vci 400 is there any way to use DVS
Yes indeed. The DDJ-SX2 can run two DVS decks and two controller decks simultaneously. This is one of the cool features of expanding your setup in this way as with just the controller, you have to switch deck layers to control 4 channels.
One thing to note is that phono inputs are only available on channels 1 and 2 channels. All 4 channels support line input.
Thats awesome, i'll have 2 tracks in the mix, scratch some accapela's over it on 3th deck and have the next track ready on deck 4 :)
Correct me if i'm wrong, i'm planning on running 2x Reloop RP-8000straight with timecode vinyl next to the DDJ-SX2. Those turntables have a line/phono switch, 8drumpads, midi, USB-port and USB-link.
1. If i use line-out on the turntables and on the ddj-sx2 have CH3+CH4 set to CD-input, i can map them to deck 3+4 in serato(DVS)?
2. Whats the difference between PC, CD and Line inputs on the DDJ-SX2 channels? (phono i understand, low outpout>needs pre-amp)
3. The turntables have 8-midi pads each, same with ddj-sx2 decks. So all 4 decks can have its own set of 8 cuepoints?
4. There is also a browse/rotatry-knob on the turntables, can i re-map them to FX in serato? (1browser knob on sx is enough)
For your questions:
1. As the RP-8000s are accessories and not fully supported devices, I'm afraid they can't be re-mapped at this stage. This is something we hope to offer in the future.
2. PC means the input is from your computer via USB; some devices say USB in this instance. Line and CD are actually both just 'Line'. Pioneer has put Line on channels 1 and 2 to signify that these are the DVS capable channels (whereas 3 and 4 do not support DVS, but can take a straight audio signal - from an audio CD for example).
3. No again sorry - cue points are universal. If you have cues mapped in more than one place, all locations will trigger the same points.
4. Same as for 1. sorry, the RP-8000s can't be re-mapped at this stage.
Great ideas! When these things are possible, you will have an awesome configuration :)
As for question 1, maybe mapping was the wrong choice in words.
Is DVS-functionalty limited to (hardware) channels 1 and 2 on the DDJ-SX2?
Or can you use a CDJ (or turntable that puts out line-signal)with DVS on all 4 channels?
I dont mind which channel corresponds to what deck in serato, but like to have the outer left turntable (or cdj with dvs) on the outer left fader on the ddj-sx2.
So in your case, you can absolutely have CDJs or your RP-8000s on whichever channel you like.
Nice setup :)
sold the rp8000's and sx2, bought technics 1200's.. some habbits die hard
Hit up the support team by opening a help request (button next to comment box) if you are having issues.
Every single club ever. If Serato being unable to track with lots of bass resonance from the booth/subs/stage. I get this all the time. Mostly end up using CDJ because of it :(
Isonoe feet really help I think, as well as a good constructed booth (good luck finding that).
The worst thing about Serato is how picky it is for turntables - a poor cartridge connection on the tone arm or stylus cartridge might play fine for 'real' vinyl but running through say an SL3 or something, it will not only change things like 'ground hum' issues into what sound like 'RF' noise, but also potentially *NOT* run properly at all. Sometimes I get infinity symbols from bad tonearm connections.. but similar poor tonearm connection works fine for 'real' vinyl (or 'fine enough' to at least get two channels coming to the audience). Drives me nuts really.
when that happens are you getting pitch waiver?
when that happens are you getting pitch waiver?
By the time the vinyl is worn a bit, yeah you can get a little glitch here and there from bad tracking :( but it means to change my vinyl.. but I just feel I'm not getting as long as I should with some pressings. I'm thinking the picture discs are crappy.. another -1 for my DJ Premier pressing.
Ninjagaijin do your control records play okay on other turntables? Do you experience drift with vinyl?
Kimosabby this drift is quite small but do you find that it is constant? Does it only happen after the needle has been on the control vinyl for some time or right away?
The control vinyl play fine on mine or at the club, I kind of expect wear and tear since I'm doing backspins and a lot of cueing, playing the same side over and over for hours on end hehe.
I am thinking drift 'changing rpm' you are either talking about turntable setup (the rings on the platter and drifting from stable position meaning you are not calibrated right) or the decimal place going up and down by 0.3-0.4 % bpm. Agree that that normal wow & flutter. Perhaps it is just with poor sensitivity or worn control vinyls or worn needles or bad booth or combination of all takes that wow & flutter and makes glitches out of it?
By beeping do you mean the constant tone that comes when you have the control vinyl playing? If so, I'm afraid the answer is no, you can't eliminate it.
That tone is what allows Serato DJ to match your music files to the movement of the vinyl and needs to be quite loud in order to have good tracking. When I first started I used to find it a bit off-putting as well, but you do get used to it.
Thanks for the quick reply. I hope you are right and my wife doesn't kill me before she gets used to the tone :-)
The other option is to use INT mode when noise is an issue... Not a fantastic option as you then don't have deck control, but at least it's quiet :)
hello! I also encountered the same situation as you, could you tell me whether you solved? How to solve?
The actual RPM of the turntable is a physical hardware parameter and can't be resolved in the software. Or are you referring to the BPM of the track fluctuating within Serato DJ?
If it's the BPM within Serato DJ and you think there is a technical issue that needs resolving, best to open a help request at support.serato.com so one of the team can work with you to see what might be happening.
No current plans to support the MP2014 sorry.
Sorry to hear you had a bad experience with this ninjagaijin, what model CDJs were you playing on?
