NO WHERE did I say I was going to use the 3805
in place of the CAV6.6. Did I! go back and reread.
This will be difficult but think out of the box!!!
Inputs and outputs don't care what they are hooked
too - FOR THE MOST PART. In the past - before
anyone was making multi-source/zone boxes you
would use a tape loop and your record selector
to do the same thing - two zones multiple sources.
The 3805 has over twice the electronics as the
CAV6.6. By recofiguring - not adding just reconfiguring
- the available capablities inside the 3805 I
could have 3 zones powered (six of the seven internal
amps and if you scaled those down you could get
6 zones at 60 per channel per zone) with over
10 input sources including one tuner built in
and 10 zones without power with both digital and
analog capabilities. Now do you understand.
Why can Denon make a 3805 with all it's capabilities
and quality and the "CUSTOM" crowd be so much
higher in price but overall lower in capabilites.
Yes you do have the economy of scale involved
but it would be nice if it worked for us and not
against us.
Ok, ok so you plan to use all the amplification inside the 3805 (Hmmm) can you show me what protocol commands you are using to control the different sources and different preamp levels? I have been unable to see the status commands for this as well.
As far as what input to what output, sure the inputs and outputs don't care, but the MUX and signal processing does! Look at the data sheets of the MUX circuit and chips, you will see exactly what they are capable of. But beyond that the control of the unit is why you would not want to use it in this fashion. BTW what kind of keypads or user interfaces are you using for these 3-6 zones? Are you talking about just using the RC-617 and an IR remote control?
What would you say the total cost of this kind of a system is? Have you installed this in a job? How many jobs?
The MUX chips in the 3805 have only a single two way MUX gate this allows only the receiver and the zone 2 preamp out to be processed through the DSP. The 3805 does not support ANY digital signal processing for the 3rd zone output. In zone 3 they do a clever trick on the board with a two way logic gate before the MUX so that they can deliver a fixed preamp level. This means you need additional pre-amplification, amplification and controls to make the 3rd zone really do anything. I stand by my previous post in that designing a job with this 3805 receiver for multi-zone multi source is not the best possible solution. For an $1100 receiver this is a very cool component, but you got to be kidding me if you think the very basic MUX in this device is even in the same league as some of the matrix switches on the market.
