Making 4 channels turn in to 9

[maddogmike]

Hey out there

I'm just getting into the audio world, and have a few questions about the use of DSP with a head unit

ok lets start out with what I have

Mcintosh MX406 head

ID xs65 and xs69

2 MCintosh MCC204 amps

1 Mcintosh mc425 amp

Audison 1 Bit dsp

JL12-tw3

Here's my question

the head unit only has 4 channels out ,the dsp has 8 in and 8 out. How will I make this work? Also on the MCintosh amps have a "PG" out put but the head unit only has 1 input how will I wire this up ?Daisy chaining them together?

Thanks

The DSP only needs a L and R in to send out 8

How many speakers are you trying to run? Why would you possibly need 9 channels?

 

[maddogmike]

I'm looking to run each front component on its own channel

so

2 channels for front tweeters

2 channels for front mids

2 Channels for rear tweeters

2 channels for rear mids

1 channel for sub

You don't really need tweeters in the back. You don't really need anything in the back unless your DSP supports 7.1

I know your right but I have them already they say they have a very good midrange

They are ok. Depends on when they where made. Pre power bass buy out or after

Your processor isn't capable to do what you want so you would have to either run the rear speakers with their passive xovers, buy a second processor which I think would be kind of overkill at your level, or get a single processor like the Helix DSP Pro which has 10 channels of output.....
