Mackie CR4: balance makes no difference when adjusted, CR3 won´t power
I wonder if someone here can please help me.
I purchased a set of Mackie CR4BT studio monitors and a pair of Mackie CR3 studio monitors. The CR4BT active monitor works but the passive one won´t. And adjusting the balance on my computer seems to make no difference. i.e, left/right or center the active speaker stays on (and plays music)
And the Mackie CR3 monitors just won´t power on at all.
I´ve tried the plug fuse, checked the cable, made sure the power switch is on but still no joy out of them.
The warranty is over so I have no problem opening them up, I just don´t know what I should be looking for
Please can someone offer me advice on these?
