Hi,

I have 2 OA03 cards installed, and using all 8 channel RCA outs.

If I install a new OA12 card, can I choose which channels to output in this card?

Namely I would want to use Front channels + Subwoofer out... can this be done?

Cheers

If you install the OA12 card, follow the instructions and you should be fine. It's just a matter of setting the links correctly.

INSTRUCTIONS FOR FITTING ADDITIONAL ANALOGUE OUTPUT CARDS TO A MERIDIAN 861 (OA02,OA12).pdf

Double-check the links on the remaining OA03 card to make sure that nothing is clashing.

Then run the Mconfig program to set the rest of it up.

Good luck,
Steve

Is there a big difference in sound quality with the OA12 vs OA13?

I thought the Meridian 861v4 would only go up to 96KHz anyway so why use OA13 that does 192KHz?

Aren't all sources downsampled to 96KHz when entering the 861v4? Or upsampled from 44/48 to 96?

The OA13 DACs up-sample the digital 88/96k to 176/192k prior to analogue conversion.

So does my current OA03 do the same?

So given i have 2x OA-03 and using all 8 outputs , if i install the OA-12 can i get all 3 to work at the same time ?

If configured as Setting 1, do FL , FR , C and SUB will be sent at the same time to OA-03 and OA-12 ?

Does in this config, the OA-03 will upsample to 192 and the OA-12 to 96 ?

Sorry for noob, must be sure before i get it.
