5.1 Amplifier?

Hello -

I noticed that most all configurations for a 5.1 setup are utilizing ACTIVE monitors with an audio interface (such as those by M-Audio, Presonus, etc..).

But I was wondering what if I wanted to utilize a PASSIVE monitor setup....is there a 5.1 amp out there made for this? I've researched a bit, but have only seen amps with stereo capabilities.

I know there are home theater receivers that are capable of doing this, but they would probably add "color" to the sound.

Any possibilities that anyone can suggest for this?

If you're going to go out and get six discrete, passive speaker systems, you can probably manage to get three stereo power amps to go with them. The lack of equipment in that area is rather an indicator of what the preferences of the mainstream pro consumers are.

Yes, I kinda thought that myself but was curious how the users of "passive" monitors were powering their systems.

I've got an old 6 channel NAD. It's only listed as 30w per channel, it's in my living room surround set-up and it's plenty loud. I use it with a Technics digital sound processor, to break out the digital audio into 5.1
It's a very clean amp, I like it.

So you're not using this connected to your computer?

Over the years I have used that amp in many ways. I did have it connected to my Focusrite Safire Pro 10 computer interface. Using 1/4" to RCA connectors, I was powering my surround Left and Right, as well as my centre speaker. I bridged the NAD amp so as to utilize 3 x 60watt channels. My Mains and Sub are already powered speakers. My plan was to mix in 5.1 but I haven't had the time to properly experiment with software and process, so I put it on the back burner. I am rethinking my monitoring situation, which is much more complex than straight stereo. I may just go with powered surrounds and centre speakers... or maybe go totally unpowered speakers, except the sub. It's still a bit of a puzzle.
I have a StudioComm Bass Manager in the studio with balanced i/o to properly assign the speakers the right frequencies.

In the meantime I am using the NAD as a listening room experience in my living room.
What are you trying to set-up for? Surround mixing?

Exactly. I am looking at all the options available to setup a 5.1 surround monitoring system. I'm no expert by any means, but will get there with practice....I hope!!

It seems the "amp" + "passive" monitors are little less popular than the "active" monitor setup.
