Connecting Marantz NR1402 to Yamaha ax592

[TheFalcon]

Hi

I would like to use my Yamaha Integrated Stereo Amplifier to drive the front LR channels of my home theatre. I am not sure if my Yahama has a Unity gain feature so my question is, can I use the coupler main in connectors to connect to the pre-outs in my Marantz receiver? (or will this remove all stereo processing from the Yahama?)

Thanks
