    Just recorded a new mix to find that when I listen back to it there seems be a constant hum in the background which kills off the mids and trebs and leaves the mix overly bassy and flat. Tried re-recording through the Booth and Master outputs but its still there, brand new ortofon needles too so my only guess is that its the mixer itself.

    Any idea what it could be? Im pretty shit at electronics unfortunately, could probably have a go at soldering something, but anything other than that and id be pretty out of my league.

    A couple possible scenarios:

    • There could be an issue with your turntable's grounding cable. Check the tip to make sure there is no rust or issue with the grounding "hook."
    • There could be some oxidation (rust) on the contact points where you input your ortonfon's into the tone arm. This can disrupt the current.
    • Could be a grounding issue with your audio cables. Are you using RCAs or a 2 to 1 (RCAs to 1/8" jack) to record the mix? These can often cause a hum, as they're not grounded and are prone to pickup electrical interference and computer noise. If possible, use 1/4" cables (balanced) or XLRs to record as these types of connections are grounded.

    Cheers.

    Where are your speakers compared to your decks? How loud were they when you recorded? Could be feedback.

    Humm = Ground issue

    Before anything is the laptop plugged in? try unplugging it and rec.
