I have a meixing MC84-A amp and i want to connect it to my yamaha RX-V677 receiver. is it possible?
the back of my amp only has speaker cable out and my receiver only has RCA cable input

there is online instruction to convert speaker cable to RCA cable, but not sure if that will work for me.

any suggestion?

You need to tap into the Yamaha's preamp section and take an audio feed from there. This would be a point either before or after the volume control, depending on whether you want the volume control in the Yamaha to be your main control or not.

Using the Yamaha's speaker output to feed into another power amp is a very poor method.

Best solution would be a separate preamp to use with your valve amp, a preamp that allows all your sources to be connected.

I see, thank you for your speedy reply 🙂
the reason i want to do that is my sub is currently connect to my receiver and the speakers connect to my valve amp has really weak bass. is there another way for my to use the sub on my valve amp?

sorry for the newbie question, i am really new to this field.

Looking at those and I would say best option is going to be a separate preamp.

If you really want to use the Yamaha then you are going to have to take a feed from before the volume control for best results with MC84.

That leaves the problem of the sub and whether you want the sub volume to be controlled by the main single volume control in the system. If you do want the sub and MC84 to work from the Yamaha volume control then you need to take a feed for both from after the volume control.

Another option would be to add line out sockets to the MC84 and feed the sub from there, using the MC84 volume control.

All these solutions are a compromise in some way. The real answer for best sound is a dedicated preamp.

So what is the problem? Yamaha preout -> sub, tape out -> MC84 (use the volume control to set the level) -> speakers. Or use a Y-splitter to drive both the sub and the MC84, so you can use the Yamaha to control the levels of both.
