Yamaha RX-V2400/1400
Okay, now were playing is explosives!
The Yamaha RX-V2400 is a 7.1 receiver:
1. Front L
2. Front R
3. Center
4. Surround L
5. Surround R
6. Surround Back L
7. Surround Back R
0.1 Sub
You can make it emulate a 9.1 by adding two presence speakers to the spring loaded clips for Presence/Zone 2 speaker connectors. I guess the comment in the review about lack of binding posts for the presence speakers was because they are clips not posts like the others. Bear in mind that unless you have "surround back" speakers connected to the surround back speaker posts, the Yamaha will send the surround back signal to the presence speakers unless you set it up as Zone 2. If you have the unit you will know what I'm talking about and the Yammies set up procedure.
Hope this clears thing up a bit
