click in sound from main output

hello i have a problem when i recording sound from my mpc (main output) on my hard disc recorder hear sometimes click in signal problem is not in hard disc input because when i record other signal on hard disc i not hear artefacts

check your cords....

check your levels....

the levels and cords are OK

how often are the clicks coming? Is it dependent on the tempo of the song or pattern you are sending out?

it's not dependent on the tempo song and pattern i hear this click in every song and pattern

I forgot ask if the click gets louder or lower if you adust your volume levels? And for want of just totally trouble shooting try turning off the metronome

i turning off the metronome and the click is not depend on the volume level
the click is similar like when is problem with latency

What about your MASTER volume, not the knob or the mixer... did you try turning the MASTER down?
