Biamping with very different amps
george, the suggestion of using a volume control device such as Schiit Sys will not work in this particular situation since that will reduce the overall volume going into the preamp and not change the gain of the amplifier. Read again, the Shiit is to go between the active preamp (or kube if being used) and only the power amp with the highest gain, so to just reduce it to the same gain as the other power amp. Then the active preamp will be master volume. Cheers George |
n any event, though, the KUBE would probably make that a moot point, while leaving the other issues I cited unresolved.If a Kube is used then it would drive the (lowest gain) poweramp and also the Schiit, which drives the (highest gain) poweramp, then the main volume control duties are up to the active preamp. Cheers George |
Hi George, The KUBE would allow the gains of the two amps to be matched without using a separate passive volume control. See section 3.6 of the following document: http://www.kef.com/uploads/files/en/museum_pdf/90s/Reference_Series_Model_107_2_Installation_Instruc... Best regards, -- Al |
Hi Al, not on the Kube I once had used, looks like the op’s one is different and has high and low gain controls, if so and he has the range to match the amps, then yes no need to use a Schiit passive then. If not get the Schiit is only $49. That way he can also do it without the Kube in, as it’s full of opamps TL071/2 from memory, and they sound very soso in the mids and highs. http://www.canuckaudiomart.com/details/649052620-kef_kube_1042/ Cheers George |
