Hi!
I recently both Prime GO and I’m noticing audio distortion/clipping in case Channel feeder is on approx. 2/3 and master on 2/3 or higher. Same issue is happening if Chanell feeder is on half & Master is on 3/4 or over. On lower volumes everything is normal.
This behavior seems to me not normal. As my device in under Warranty before starting claim, I would appreciate if someone can confirm me that this is not normal.
Thx in advanced!
Hi, can you create a video and share the link so people can see it happening.
Also details of what you are connecting it to, the volume level of the connected devices etc etc. And photos of their settings if possible. There are many factors that might be causing this in the signal chain from music file to speaker output.
Hi,
Blow is link to video which shows what is happening (on beginning sound is normal, and after incising Volume clipping starting to happen, further increase of master make it even worse). It can be reproduced with any track doesn’t matter on bitrate or any other parameter. In video I’m using home audio system with Marantz amp (flet EQ) connected with RCA and B&W speakers + 600W active sub . Volume in amplifier was on less then 1/2 and overall volume was significantly lower what speakers and amp can deliver.
Same issue is happening on PA setup.
So first thing I noticed was your level meter peaking out, have the files been normalised to a level that is too high? You should have a steady flashing of LEDs in time with the beat.
As far as your levels go, I don’t think I’ve ever turned the master up to anywhere near that at home or a gig, mine rarely goes past 12 o clock.
The channel trim sits between 11 and 1 usually for most of my tracks, again I’d never have it all the way round to 3oclock… even my quiet vinyls rarely get that far on the trim.
The first part of the video sounded fine and it was also at a point where I think the levels should be for normal use, I’d then turn the speakers or amp up to get more volume.
Hejsan! 
I couldn’t see the channel LEDs clearly in the video (the ones above the crossfader), but turning up the channel gain (labeled “Level” here) too high on a mixer will definitely cause distortion. Check the channel meters: if they are hitting blue, it is a sign the level is too much …
There isn’t a single gain/level setting that works for all tracks. We need to adjust the gain for each track and monitor the channel meters, especially when mixing two tracks, because the combined levels can push the signal into distortion.
If you turn up the master level too high, you could also overload the next amplifier in the chain. This can cause distortion and even damage the amp. 
Send a well-balanced signal to the amplifier and let the amp do the hard work. On Pioneer gear, the gain/level/trim pots are often set to 12’o clock. I have met several DJs who think that this is the standard or default position - but that’s not necessarily right … and many DJs redline which is when the audio signal is too strong and clips. With our Denon DJ gear, it would actually be bluelining … it is still bad.
If the signal from the Prime Go is already clipped, the PA won’t output a clean signal. Check how your system is set up. If the Prime Go were just a mixer, you would first set all gain/level knobs and all faders to zero, then increase the level until the loud parts are somewhere between green and white. There is usually a sweet spot where the signal-to-noise ratio is optimal (check the Prime Go manual if there is some info). With the faders up, adjust the main output level so that the next element in the chain gets a clear signal that sounds good during the soundcheck. You should not get distortion with faders at 2/3. Let the PA handle amplification. If you’re at a larger venue, your equipment might be connected to a Front-of-House mixer or something similar. If you need more volume, it should be set there …
I hope that this helps you to find the cause of the clipping/distortion. Channel clipping is a frequent problem. And sometimes a quieter signal is what the next part of the chain needs.
I’ve just noticed too, the overview waveform on the track being played is massive, way higher than most of mine.
Thx for the tips guys! I appreciate your help.
I understand what you are telling me and that is way how I’m doing…I’m also aiming to have gains on 12’o and adjusting channel pot depending on the track (to get white flashing with the rhythm).
Clipping is definitely happening on mixer output (amp or speakers are away of overload).
But…I’m wondering is it normal to get clipping on properly adjusted output of the mixer (led on level meter don’t hit blue led) and I go with the master level on 3’o or over? On my previous device this was not the case.
On the video, maybe channel level gain was bit to high (white was not fleshing but blue wasn’t hit at any time).
I’m not pro DJ, but I’m in this hobby for more then 30 years 
, so I have “some” experience.
I play a lot of genres and nearly always the level meter is steadily rising and lowering in time with the beat, for it to be solid like that I’d say it’s over gained, try having your trim at about 10 o’clock.
The waveform looks saturated on screen so it might just be an extremely loud track, or it’s been mastered too high.
Yeah. This doesn’t sound right.
The sweet spot for your master output has a bigger dot on it (about 2pm). Even going to 3pm like you did, I wouldn’t usually hear distortion like that.
Ensure that your channel gains are hitting 0dB (or just under) and double check all connections to the amp and that the cable is a decent one. If you have another amp then maybe try that. It could be that the amp is sensitive and just doesn’t like a strong signal.
Looking at the waveforms, I can’t see any clipped peaks which I would have expected to see if the source was distorted.
With the Prime Go there was an update recently that added channel gain metering. Now you can switch to this in the mixer settings so you can see your input gain visually. The way it’s been implemented is a bit of a pain due to it being a menu dive when you want to switch. Just having it display the master output levels on the meter when no headphone cue button is pressed and then the channel gain displayed when the headphone cue is active would have been sweet. Instead it is this menu dive each time.
There is also the possibility the unit is defective but I’d say that’s much less likely. There’s some great advice above but looking at it you just need to check your channel input gains with that display setting.
Do you not think the waveform looks quite large though? the overview looks a lot fuller than most of my tracks, id say the peaks on mine are usually no more than 2/3 of the way up from the bottom, usually more 1/2.
That level meter with 4 solid lights and no drop also looks strange, i know its not clipping (and not owning a go i cant tell how accurate they are) but to not move seems weird.
Yes, it is possible. Even if your sound file is nice and the channel gain/level is set ok, increasing the output may pass a point from which on the next part of the signal chain cannot handle the loud signal.
For example, I can connect a synth, which has a main volume output, to a rat distortion pedal. Here I want nice distortion, but if I crank up the output of the synth too high, the rat cannot handle it and the signal degrades or even becomes very quiet. So the right way is to keep the output level of the synth low, let the rat do its trick, and send the signal to the next element in the signal chain. And with your amp it may be a similar situation … I do not know the details of your setup, but what happens if you keep the output of the Prime Go low and increase the volume of the amplifier?
Blockquote I do not know the details of your setup, but what happens if you keep the output of the Prime Go low and increase the volume of the amplifier?
If prime Go levels are low everything is right even I go to max volume with amp
Is it a line level input on the Amp
Check that your are not going to phono
It is line (aux)
I still think that there may be a problem with the gain structure: matching the output voltage of your Prime Go to the input sensitivity of your amplifier. Increasing the output level of the Go increases the actual voltage. Every amplifier is different. Also check if your amp has an input sensitivity switch. If you have found a setting, where the output of the Go sounds fine, this may be the right setting.
There is no general always-correct setting for channel gain knobs and master output. If you play a lot of music in a certain style, there are values that usually work. But generally, the gain should be set and monitored for each track. And the master output can be determined and set during the sound check. Of course you can start at a lower level and increase up to the determined maximum during a set.
If you think that there is something wrong with the Go, try out a different amp or active speakers. You could take your Go to a music/speaker shop and try out some other system, the thing is portable, right? 
I would say the same thing but it seems the issue does not depend on the speaker setup.
I have now watched the video again. This image is from around time 00:03, at the beginning. The white channel led is not flashing on the beat, it is already solid white. Channel gain/level is at 12 o’clock and the main volume too.
Now comes an image from the end, at around 00:48. The channel leds are peaking, solid blue. The channel gain/level is at 3 o’clock, the main volume appears to be set even slightly higher:
The video does not focus on the settings and the channel meter, it is hard to see what is actually going on. But I think that the signal is clipped due to the rather high channel gain. Increasing the main volume makes it even worse …
it seems the issue does not depend on the speaker setup.
Looking a the the waveforms it is consistent with what I’d see with a live track. It’s a strong source signal. I can’t see any squared ends or oversized fat bass transients with clipped peaks and as the distortion happens when turned up I’d say it points to the gain going to 3pm.
@Kre_Ka I’m not too sure on what the metering is set to (channel gain or master out) but it’s definitely turning the gain up to 3pm that causes it. The track is already a louder track as-is and then to turn it up to 3pm on the gain and then have the master out turned up to 3pm to 4 pm on top of that has just introduced that distortion. It’s overdriving the signal into the amp.
My advice would be to keep the “master out” set at that little dot at 2pm and keep gains around the 12pm. Set the gain metering in the mixer setup to channel and make sure you don’t peak over the white VU light too often. You will have to adjust the gains a little bit and even more so for live tracks but you’ll get a feel for the right levels on the Go in no time.
So to put simply, turn the channel gain down until the level lights are moving up and down and not hitting the blue peak, then work from there.
Otherwise known as standard DJ practise.
It’s amazing how the mind can play tricks on you.
I watched that video and that blue seemed OFF because it’s so dim next to the super white white one
