Default USING 2 2x4minidsp is possible in a 3 way system?

Hello.

Id like to build a chip 3 way crossover, so Im wondering to buy 2 minidsp 2x4 and configure like this:

Option 1:
1 miniDsp for left channel and 1 minidsp for right channel.
In this configuration, I would use just 1 input of each minidsp and 3 of the 4 outputs wil be used for Tw, Mid and Woofer left channel.

The right channel would be just the same with the second minidsp.

Option 2:
1 miniDsp for Tw and mids (left&right channels) and 1 minidsp for woofers (left&right channels)

The right channel would be just the same.


Do you think this works?
Thank you

Yes, either of your options will work. I think I would probably select option 1 and use the 4-way plugin for both boards. That way your plugin configuration is identical for both boards.

Hi, yes it works, I did it here: http://www.hifizine.com/2010/12/prot...e-minidsp-2x4/

However, you can't "talk" to two boards at the same time. So you have to plug and unplug the USB cable between the two units while setting them up. I'd say option 1 is the most convenient. But a 2x8 or nanoDIGI is much easier (and has other advantages).

A 2x8 is nearly 3.5s the price of 2 2x4s if talking the unbalanced ones...and 2.5s 2x4 balanced.

Glad it would work...been thinking about getting one to get me by until my system expands and would need another one.

But I swear I read somewhere that it was not recommended to run 2 of them in your system together.

If you read that somewhere, it was incorrect. You can certainly use multiple units in parallel if you like. I did that when first starting out with miniDSP. As John mentioned, you have to load/talk with each individually so it takes a little more time, but you get used to it quickly.

So, what happens is that I have to measure and programm twice, isn't that?

Or maybe I have to apply the same plugin to both minidsp and measure them. Any change would be done in both channels.

No, you don't have to measure twice. I can't think of a reason to EQ differently your left and right channels, so any changes you implement you would apply identically to both channels.
