We are not all made equal and normally size doesn't matter, but in this case... it does.
Some patch cables are slightly smaller spec than what the audio jacks expect.
It's a very tiny discrepancy but it will cause some movement within the jack which results in unpleasant noises.
You can do a very easy mod that will eliminate this issue
Just add a jumper from the ring to the sleeve.
- we didn't think we would need this but it has now been updated on all new Echosystems.
This will not void your warranty.
There ya go! Happy little Echosystem :)
