Here is a unique connection, not so basic ? I have the following connected to the same RTi10 speakers via the PSW505 sub:
1. Yamaha RX-V2700
2. Marantz SR-320 (early 80s receiver used for music).
Both are connected to my PSW505, then bi-wired out to the speakers from the sub. Separately, from the back of both receivers for the main speakers, I have speaker cables going to the speaker input of the PSW505.
I have the positive speaker leads from both receivers joined together at the sub end, into a banana plug into the PSW505, and the same for the negative set of leads as well.
I never have both the Yammie or the Marantz on at the same time and all appears to work OK . This gives me the best of both worlds - Marantz for all music and Yammie for HT / TV etc., but I am curious to the likelihood of possible damage to any of the components, or if the receivers will see a different load thinking there are more speakers etc?
Thanks in advance for any thoughts / advice .
