Help? Bi-Amping With A Pair of Roksan KA-1 Amplifiers

One amp is doing mids and highs, and one is doing bass duty.

Don’t pull anything leave the jumper bars intact, on the Integrated.

Remove the jumpers on the speakers

Hook the one with no trim to the left and right speaker bass sections.

Hook the one with trim control to the mids and highs, left and right speaker terminals.

Kinda different, but will work as good as you’re gonna get it. Just two volume controls. One for the bass one for the mids and highs, with trim
(balance, treble, and bass (hopefully)), on the mids and highs.

It's pretty straight forward, You might want to use a little heavier speaker cable on the bass (copper is the best) and better quality for the mids and highs, No need to get crazy just smaller, better cable. Be careful with clad wires they can be on the bright side. Silver over copper, that kind of stuff.  pure copper, pure silver, some clads if they are thought out, properly...

And don’t be sorry, I never have been, apologised a time or two but NEVER sorry... :-)

See if this link takes you to an article about bi-wiring and bi-amping, and scroll down to the last diagram pic near their conclusion that illustrates the difference between vertical and horizontal bi-amping...might help you visualize.

Here's another link that has some pics - http://av2day.com/2014/05/bi-amping-vertical-vs-horizontal/

Either Vertical or horizontal bi-amping could work for you, but it’s important to pick one and not confuse them. There are pros and cons with each. Regardless which, you will be doing "passive" bi-amping using your speaker’s internal crossover ("active" bi-amping is another option for some situations, but it doesn’t sound like it’s feasible for you at this time).

The "vertical" method dedicates one amplifier solely to the left channel, and the other amp solely to the right channel. The markings for "Left" and "Right" on the output of your amps become irrelevant....one is going to become the woofer channel, and the the other the mid/tweeter channel. Split your music source signals between the two amps....left output from CD to input of the amp going to the left speaker, and left output phono to the phono input of the amp going to left speaker.... then right output from CD to right speaker amp, right output phono to right speaker amp. Left and right sides are completely isolated from each other, and will have separate volume controls in this configuration....the stereo effect will occur at the music source. Make sense?

p.s. It just occurred to me that you will need a y-adapters for your CD and phono cables.

Thanks so much for the advice guys. I will start experimenting with this.

BTW, I picked up a KORG DS-DAC-10R AD/DA converter (new) to rip some vinyl. It also appears to function as a pre-amp. I am using a Luxman TT with an Ortofon Blue MM cartridge. Would using the KORG be better than the Roksan on-board phono section? If so, where do I clamp this, to the Tape In or one of the Line Inputs?

Thanks again.

You have to listen and see, which sounds better. CLAMP? Your gonna hook it up, LOL The tape loop will get the signal from the Korg, to both amps with one cable by using the "TAPE LOOP". Horizontal bi amping is what you're doing...Not vertical. Different amps work better horizontal.
