digitalgon, you can not do this without a gain control on at least one of the amps. It is a bad idea anyway. Get a dbx DriveRack and do it right bypassing the woofer, midrange crossover in the speakers then just dial in the same cross over and slope into the drive rack.
Vertical bi amping Mcintosh MC275 and Rotel RB-1582 MkII
Hi all,
I've been researching the title project but not getting any productive results. Basically I'd like to know if the volume matches between these 2 amps. The problem is both amps are not identical and don't have bias control so one maybe louder than another. I don't want to add a crossover or volume control in between.
The MC275 (v5) will be driving the high and RB-1582 MkII will be driving the low of the speaker, which is B&W 803D My goal is to add more punchy mid low as MC275 is somewhat too gentle to some music.
Hope someone has done this and can share the thoughts with me. Thank you.

For them to be identical gains, would be very very lucky. All you have to do is put a $49 Schiit Sys passive at the input of the louder of the two amps an set it just once it so your amps are then balanced to your ear, this also gives the ability to give or take a little mid/highs or bass to balance out bad recordings that are too bright or too bassy. https://www.schiit.com/products/sys Cheers George |
What you are describing to do is horizontal biamping ( passively ), and George, is correct. However, I feel both amplifiers have enough sound character differences between one another, that you may find a discontinuity in sq between the woofers and the mid / tweeter sections when listening. Only trying it yourself will determine what you think. |
