Hi everyone, I’m new to synths and recently bought a Sub Phatty. I’ve plugged it into an amp but can’t seem to get any sound out of it. I tried plugging a jack into the KB gate and only got a drone hum sound that I couldn’t control with any of the knobs. The only buttons that are lighting up are the LFO rate and the top path preset. Pressing any of the others doesn’t seem to do anything.
Any help would be much appreciated, thanks in advance. 
Your amplifier should be plugged into the jack labeled AUDIO OUT. There is also a jack on the front for headphones. If you don’t have an owner’s manual you can download one here:

Thanks for your reply, it seems the issue is that I need a power converter as I am in the UK and the synth came from America.
I understand the internal power supply is able to make the conversion internally. That shouldn’t be an issue
It seem to me like an unproperly installed firmware
Oh right, in that case how would I rectify this?
