Thanks a lot for this video! I'm going to use on of these tomorrow at a gig and felt very unsure of how it works, so much clearer now!

Doing a show with one of these soon, very helpful! thanks

Hey I have this board and cant get any audio out through a mic to my PA what could be wrong?

Question: I picked up a used O1V but am getting nothing out of the master stereo XLR outputs. Master fader is on and channels are routed to master. Also everything comes out of the monitor outs. There is a light ground hum coming out of the outputs though. Ever have this problem? Any idea what's going on? Master output blown??

when you are editing the eq use the d pad to scroll down to the q section on the eq and then use the large wheel to change the q setting

does it have true bypass, straight thru without any digital processing ?

i need it for a church

I want program for contron O1V you have ?

hey my name is Avery do you have the yamaha o1v

not have return no?¿
