I've just bought the PreSonus R65, I believe when I first used it the both speaker were working fine - for the first use.
Now I only hear sound from the left speaker. When I pan audio all the way to the right I can hear very faint sound, like it's passing through a high pass filter. I've tried switching power outlets, changing cables, swapping audio interfaces, changing programs and yet nothing seems to fix this issue. When I use a tone generator in Ableton sound only comes from the left speaker.
Why does this happen? Is this a problem with the hardware or have I done something wrong in the setup that's easily fixable??
