Let me start by saying what you are about to read could be full of ignorance on my part so please be patient.
Here are my two questions:
Using the equipment below, can I Bi-amp (not BI wire) my speakers using the equipment mentioned below? And if the answer is yes, then would it be recommended to wire to the AVR specified suggestions of using the surround rears via a pre-out (i am guessing) or to use an RCA splitter for the fronts?
I am attempting to vertically Bi-amp my speakers using an external amplifier.
I have provided links to the Marantz owners manual covering the my two areas of instructions.
in case this forum prohibiting me from posting direct links so add Marantz . Com to the front of these
/CINEMA60/NA/EN/DRDZSYcqhsmjdu.php (bi-amping speakers)
/CINEMA60/NA/EN/DRDZSYqibytsvl.php (connecting an external amp).
The instruction indicate using the surround rears to wire for bi-amping using the internal amplification of the Cinema 60. (not my goal) As far as I have been able to find it does not indicate the same procedure for using external amps using the pre-outs. I can only assume the procedure would be the same using the pre-out fronts and rear surround would be the same.
Now here comes the fun part and where my ignorance will really shine through. I correctly used the term external amplifier in the singular not multiple. The amplifier is a "Legacy Audio IV4 Ultra". it is a class D amplifier with four independent modules with each module having its own transformer providing separate amplification to each of the four channels. As I understand in layman's terms, it is 4 mono blocks in one chassis. While I am absolutely in love with the Legacy Products and how they sound when it comes to online manuals they are way sub par.
In their image gallery you can see the internal components.

As you can see there are four separate modules internally
The difference between the IV4 and the IV4 Ultra is the number of independent internal amplification boards. The IV4 has two modules driving 4 channels and the Ultra has four modules driving four channels.
next is their lack luster owners manual that includes all of the ultra amplifiers in one manual. (I can only assume that because each processor/AVR is different they leave it up to the processors instructions on how to accomplish this.)
I think just adding a h t t p s and the two //: to the front of this brings you to the IV4 Ultra Manual at legacy audio.

on page 11 of the owners manual named IV1-4 Ultra Amplifiers, are instruction on how to connect a seven channel system. What is pictured is an IV7. nowhere in this manual is the IV4 Ultra pictured showing the rear of the unit. but it is in fact a four channel out with four boards internally. I am not sure how to go about utilizing the capabilities of this Amplifier with this AVR. Ok third question, If I were to wire the Pre-outs using the front and rear surrounds one to each channel of the Amplifier and then wire to each of the the four binding posts on the back of the speaker, does anyone see any potential harm being caused?
Thanks for any thoughts on this!!!!
