Mixer Diode

DC polarity mistake. should i start to worry?
I recently bought a Dj Mixer (omni control from Numark). It says that it can accept a 6V 1A DC power adaptor. There was no indictation of poloarity no were. I tried to contact support but with no success.
I decided to give it a shot and try (silly me but anyways). I first got it wrong and left it connected for just about a second or less. Then i switched polarity and everything seems to work well.I didn’t hear any sparks or fuzz or smell anything. But I am still worried if i damaged some things which i dont know about.Since i read a lot about fried diodes and stuff.This is mixer with a soundcard in-built and can powered by usb instead. Could something go wrong with it? Can 6volts damage the equipment?
Can sound quality from the soundcard be effected?
It is cheap, easy and cost effective for electronics manufacturers to include diode protection of their equipment. If they didn’t, the number of returns would be unbearable, the arguments interminable and their reputation irrepairable.
Some even place a bridge rectifier configuration at the power input, so polarity becomes unimportant.
These are both “1D10T” protection devices.
