Default minidsp ADC

I'm looking to get myself an active crossover as I'm moving into 2-way (and up) speakers systems from full range systems.

I have a question about the ADC part of the minidsp. I have a sizeable collection of vinyl, cassettes and like listening to analogue radio. Please can any users, or even the maker, give me any insight to the quality of this part of the system? I'd hate to go active only to degrade 3/4 of my music sources

Many thanks in advance

James

James - I play vinyl most of the time and haven't found my minidsp to be the limiting factor: the speakers, placement in the room and the room are.

Thats good news!

I imagine the set up is: vinyl source - mm pre - pre (with volume) - minidsp - amps - speakers

Is it better to use a volume control after the minidsp to make sure maximum signal get to the inputs of the minidsp?

probably the best option is to do the volume control IN the minidsp, with the potmeter connection.

do you mean the actual chip?

if not the minidsp changes all info from analogue into digital (ADC), then applies the processing (dsp, crossovers etc) and then from digital back into analogue (DAC)

What type of volume control does the control provide? Is it a reduction in data bit depth or a 'proper' volume control?

No its not a new product. Its part of the way the minidsp works as posted above. All the processing is done digitally so analogue info must be digitised (ADC)

Any ideas on how the volume function works?

Om nanoDigi it´s digital volumecontrol.
I once owned a minidsp where you connected 1 single pot to the board
so I would asume its ´s digital.
