Biamp Connections without Pre outs

[Eworld]

Here's the setup: I have 2-Hafler DH220's which I would like use to biamp my front L/R speakers. I have an Onkyo TXSR604 as my integrated, and Fluance SX-HTB's, with the entry level Hsu sub. I also am using Monitor Audio BFX Bronzes' for 7th channel...but I digress, Since the Onkyo doesn't have pre-outs I procured a Carver Wide Band line level converter and experimented with the bi-wiring the front channels, the question is how to connect the two haflers (currently wired with one amp for the lows and one for the highs) into this setup. I tried splitting the inputs: Right amp right channel and Left amp left channel but it does not work properly (one channel is missing the highs while the other is missing the lows) so obviously with only one input point utilizing the Carver line level converter I've got a problem. What am I missing?

I drew up a quick diagram for what I believe your trying to achieve. Pardon my art skills but this is what you should have hooked up. I think your mistake is you only have hooked up one channel to each of the amps. Therefore why you only have half the sound from each speaker.

It's called paint Haoleb. The paper and marker is old school, but I guess it works.

DUH! Thanks so much! I've just completed the connections and have been testing. On my setup I've noticed an audible difference with the biamp setup.

Glad to hear it was a good upgrade.

splitting line level

Is it OK to split the line level? and if yes how?

I have a related problem. One pre-amp with two line level out, two amps and one powered sub-woofer to drive.

You can split the line levels with Y-adapters, it's OK. What are you trying to do?
