i like the sound of this system a lot but is there any way of using the pre out and an external amp to give the front floorstanding speakers better sound?
also, where is the pre out located? is it a plug? or am i missing something?
thanks for any help you can provide.
Easiest way to explain this is your receiver (AVR) serves 3 functions in one unit. It serves as the tuner
, a pre-amplifier
and a power amplifier
. Before AVR's became available we had to buy each of these units separately.
Your Denon receives a signal from an audio source and then routes or "pre-processes"
audio signals to your internal amp from various sources (ie; CD player ect).
It also "amplifies" the sound and sends it to the necessary channels. In the last few years, video processing has been added to many receivers and they are now called AVR's. Which is what you have.
Now with all these functions (including video processing) being performed by one unit it has been said to take away from the overall performance of the unit. Therefore many people have added a separate external amplifier in order to get the more power to the front speakers for example. An external amp will bypass the AVR's internal amp and send power to the speakers you connect it to.
In order to do this your AVR needs a connection called a pre-out. Without this it will not be possible to attach an external amplifier to your system. From the looks of your Denon it doesn't look like you have one.
What I reccommend would be upgrade your AVR to something a little more powerful and has pre-outs. Then if you are craving more power you can always upgrade to an external amplifier at that point. Hope that helped!!
