I did the exact same thing as Rwwear but had no preamp. The XLR outputs of the cdp were sent directly to the power amp while the rca outputs went to the sub. Both cdp outputs are variable so no preamp is needed. It was not difficult to get the sub adjusted to mate with the monitors using this configuration. You should have no problem going this route from the Krell preamp. Both the sub and the speakers are fed the full frequency spectrum with the sub crossover and level controls adjusted for a satisfactory blend.
Using Krell rca & bal outputs for the same channel
Why would I do that?
My sub has a highpass filter above 65hz. The dedicated sub channel can have info above that. So how can I get the missing freqs above 65hz. I can get a second sub but I’d rather not.
Since Krell’s RCA & balanced outputs are active at the same time, I can send the sub channel to another speaker using a Y cable to get the missing info. I’m thinking if I must use a Y cable and overtax a speaker with sub info, I’d send it to a rear speaker.
Does anyone know if using both outputs will affect the sound? The manual says that both outputs are active but to connect using only one. Will there be impedance issues? I also have an Audyssey EQ between the PrePro and the amp, so I would use the Y cable from sub and one of the rear to the EQ’s rear channel which will turn the analog signal into digital for EQing and back to analog for the amp.
