I have some Bi-Wired Q1 Series Kef Speakers. And my old Amp for them seems to have broken. Luckily a friend of mine has lent me his Amplifier, so I am able to re-power them.

My old Denon amp had 8 outputs, 4x +- pairs. And for the Q1's it meant i needed to run two cables for each speaker and it worked mint.

This new Amp I have been lent is a Yamaha RV563 i think. And it is a 7.1 output type amp.

It has a lot of outputs on the back. But I have not figured out how to wire up the KEF's to it. I tried it and got a LOT of treble and no bass at all. I assume I have done something wrong here. Any help would be appreciated.

See if you can configure it for bi amping with the secondary zone outputs, and then plug the other cables in there, Otherwise jam them both into the main speaker outs if you are able to, Sometimes you can stick one banana plug thru the hole in the post, and put the other in the back of the binding post where you pull out the little plastic stopper that keeps stupid europeans from electrocuting themselves.

Or you might be able to unscrew the connection plate from the back of the speakers, unscrew the lugs on the posts and put both connections on one set of posts.  Then you only need one cable and don't risk damaging the amp.

huh? it means you haven't bi-wired it. if you bi-wire it, it will work. hence, bi-wiring is the solution. (as well as using the metal plate, or bi-amping)

My Q300s have a knob that you can turn to bridge the high and low frequency terminals if you're not able to bi-wire. Do yours not have this?

Yeh I dont have those little plates. I thought about doing that, but even if i tried to bridge all that together, would i connect them to Front A or Front B?

It did say in the manual somewhere that there was a setting you could change in the advanced menu to say you were using bi-wired speakers. I couldn't get into the menu without the remote, so will have to find some batteries for it. 

Basically in the 7.1 I got a sub out, front A (2 front speaker outs), Front B (2 more front speaker outs) a center and 2 more surround outs.

I assume i use Front A?

You need to find a setting that gives stereo output through 4 speakers, you will probably find it called extended stereo or something to that effect

Edit: it will be a "surround" mode type of setting i.e. Dolby/Dolby PL/Stereo/etc

As I said earlier, you can bridge them internally by combining the spade connectors on the back of the posts.

And you want Front A.

connect: Front A Left Red <-> WIRE <-> either + terminal on your speaker <-> WIRE <-> the other + terminal on your speaker
Front A Left Black <-> WIRE <-> either - terminal on your speaker <-> WIRE <-> the other - terminal on your speaker

do the same with Right out and Right speaker

As it is second hand you don't know what the speaker settings have previously been set to. You can set up the A and B speakers frequency curves to utilise your bi-wired speakers. You'll need those remote batteries.

Finally got a break from the kiddies and managed to dud this out. I got into the advanced menu and turned on the bi amp then found a page in the manual on how to wire them in where the LF was out of front a and the HF is put out of surround.

Thanks four your help. It is sounding really neat!
