Hi,
I have a 130 pro firmware updated to 140 pro, and was about to take the plunge to buy another 130/140 pro to make a dual mono set up.
Then I got worried that I may need a preamplified output board in one of the 130 (140) pros in order to connect them up.
Does anyone know whether my concern is valid or not.
thanks

You need the pre out board for 390,00 Euro for dual mono

According to the configurator, you do not need the pre out if you have two 140 pro.
The connection between the two 140 is done using of the two digital input which can be configured as an output

A seperate preout board is absolute necessary!

Mmmmh. In which case there is a bug in the configurator. Because, in the configurator, you can have two 140 connected to make a 210, with and without the pre-out option.
It does not make sense to me to have an analog pre-out required since the connection is digital. The second digital input of a 140 pro can be configured as an output without the pre-out option.

The preout board is needed to switch from input to output - in this case

Gosh. This debate might need to go to penalties. Thanks all for the quick responses/ analysis. I obviously want to believe the 'it will work without the preamp output board' camp, but looks like it is not a well documented area. I have posted a query to devialet support, but dont expect a response too soon. Will update this thread when I do get a definitive response.

I've just wired up a 210 in the store in order to answer this.
Pre-out board is NOT required
