While looking at some receivers they only have a sub and rear surround preouts. Could anyone explain to me please why there wouldn't be front preouts and centre also? Thanks
You'd already have integral power for the front speakers. The TXNR509 has no integral amplification for back speakers hence the pre outs so you can add that amplification if you want a 7 channel as opposed to 5 channel setup. The addition of front pre outs is a bonus while the 509's inclusion of back pre outs is a nescessity for those wanting to utilise it within a 7.1 setup. You'd not ordinarilly get front ppre outs included with an AV receiver of this level, not unless you count one of Marantz's slimline models as being comparable.That's horrible. If am only going to add a stereo power amp to an AVR I want it on the front channels not the surrounds. Cheap b******s!
