HELP, I have gotten to where I can't stand lugging my KN6000 when I am playing somewhere. I found a used Yamaha PSR 740 today. It's about 12 pounds lighter and seems to have lot's of great features. I've heard good comments here on it. I brought it home and hooked it up. I have one big problem. I have 2 Yamaha speakers hooked to it. I seem to have no control over the volume to those speakers. I can change the master volume all I want and the volume level to those speakers never changes. The speakers are Yamaha KA10's. They originally were sold as companion speakers to a Yamaha modular organ. (The HX series.) I have used them with Yamaha keyboards, Roland keyboards, and my Technic keyboards and they work great......so I don't think the problem is the speaker. Is there a setting somewhere I haven't found to make them work with the PSR740......or is the darn keyboard broke????

I hope someone has an answer since I have till Monday morning to return or pay for the keyboard. It's not much good to me if speakers don't work right with it. It looks like a great keyboard so I hope someone has an answer!!!!
