patman Posted December 26, 2019 Share Posted December 26, 2019 (edited) Hi, ive just got a Markbass Big Bang 500 Head. Sounds great until I plug my headphones in. I’ve got a good quality set of headphones but there is a hissing noise on the right speaker. The headphones are quiet on my iPad and I’ve tried different cables but still the hiss on the right side which is annoying. The left side is quiet. Has anyone here had the same problem? Can you fix it? Help. Thanks Edited December 26, 2019 by patman Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted December 26, 2019 Share Posted December 26, 2019 Do the phones have a plug with tip and 3 rings as most Earbuds have these days? I've had unpredictable results without this type as the ground connection isn't always made correctly. Often just sounds thin, lacking in bass, in both ears though.

patman Posted December 26, 2019 Author Share Posted December 26, 2019 I’ve also tried with a brand new identical cable and the problem is still there Quote Link to comment Share on other sites More sharing options...
caitlin Posted December 26, 2019 Share Posted December 26, 2019 what does the tip of the headphone wire look like? you've posted the cable from the ipad to the amp, right? Quote Link to comment Share on other sites More sharing options...
patman Posted December 26, 2019 Author Share Posted December 26, 2019 This is the cable from the headphones to the headphones socket which has noise on the right speaker of the headphones. Using the same cable from my iPad to aux is noiseless. Quote Link to comment Share on other sites More sharing options...
caitlin Posted December 26, 2019 Share Posted December 26, 2019 so if you have the head plugged into a cab, you plug your ipad into the head using that red cable, and it plays fine, audio from the ipad and the signal from your bass, but if you unplug that red cable from the ipad and instead use it to connect your headphones then it sounds wonky in one of the headphone speakers? That cable looks really short for headphones Quote Link to comment Share on other sites More sharing options...
patman Posted December 26, 2019 Author Share Posted December 26, 2019 Yes that’s about it. I don’t have the amp plugged into a cab late at night. I sit right next to the head and yes the cable is quite short but I still get hiss in the right ear when I use a different brand new cable Quote Link to comment Share on other sites More sharing options...
caitlin Posted December 26, 2019 Share Posted December 26, 2019 I'm out of ideas, thanks for the clarification, it doesn't look like you have a TRRS issue anyway. If this thing is new you should get warrantee support, right? Quote Link to comment Share on other sites More sharing options...
patman Posted December 26, 2019 Author Share Posted December 26, 2019 Thanks Caitlin, yes I don’t think it’s anything to do with the cables as I’ve tried different combinations and still get the same problem. What does “TRRS” mean? Quote Link to comment Share on other sites More sharing options...
caitlin Posted December 26, 2019 Share Posted December 26, 2019 (edited) See how the connectors on the cables have metal bits and black bands? The metal is the contact for one of the channels or earth or microphone or whatever. The very end that you can poke yourself with is the Tip (T) then there's a Ring (R) and then there's metal all the way down to the base of the plug, which is the Sleeve (S) (TRS) If you find some headphones that came with a mobile phone or something that has a microphone you'll see there's another metal band, so there's the Tip, a Ring, another Ring and then the Sleeve (TRRS) Sometimes the contacts inside a socket aren't set up to understand TRRS and fail to ground out properly if the wrong connector is used. Your headphones don't have a microphone attached do they? Because a TRS cable might confuse the headphone end if it WANTS a TRRS.

patman Posted December 26, 2019 Author Share Posted December 26, 2019 The headphones are noisy without anything else plugged in and with all the volumes down Quote Link to comment Share on other sites More sharing options...
caitlin Posted December 26, 2019 Share Posted December 26, 2019 What kind of headphones are these? brand? model, picture? Quote Link to comment Share on other sites More sharing options...
franzbassist Posted December 26, 2019 Share Posted December 26, 2019 Try squirting a bit of contact cleaner on the jack and then putting in into the socket a few times. Quote Link to comment Share on other sites More sharing options...

patman Posted December 26, 2019 Author Share Posted December 26, 2019 (edited) I don’t think it’s the headphones, I’ve also tried putting jacks into the effects loop but it still hisses at a level that surely can’t be right? Anyone got a Big Bang that they can tell me what their headphones signal is like? Edited December 26, 2019 by patman Quote Link to comment Share on other sites More sharing options...

Oopsdabassist Posted December 26, 2019 Share Posted December 26, 2019 (edited) I think you need a TRS adaptor, as the output from the amp will be mono not stereo ie Tip (+) and ring (-) Both those cables you have pictured are stereo cables, something like tip (left channel) ring (right Channel) ring (earth/return) Although your headphones may be stereo I'm pretty certain the output from the amp wont be. https://smile.amazon.co.uk/C2G-3-5mm-Stereo-Female-Adapter-Silver/dp/B002DWAXKU/ref=sr_1_19?keywords=stereo+mono+adapter+3.5mm&qid=1577384784&sr=8-19 Something like this in your amp, the plug one of your pictured cables into that, and other stereo end into headphones, should sort it!

Not sure about that. Yes the amp is inherently mono, but the headphone socket will be wired for stereo headphones i.e. with the mono signal duplicated to L and R.
