@ lduarte,

As already answered correctly, the DIGI-FP interface is indeed the board installed in the unit. It will interface fine with your CD player. If you don't need so 8 x analog inputs, the 4x10Hd will indeed be sufficient as correctly suggested already. No need for you to get a 10x10 Hd. You will still be able to perform Digital source selection and other tweaks from the front panel/IR remote.

Hoping this info helps.

@ Spec,

Yes, you indeed can. John already made it happen! :-) You do have to be mindful that in the end, you're talking of 80W total shared across the stack, so you need to have the correct power supply for the job.

I have a question.

I have the 3 part board, DIGI - 4xminiDSP - DIGIAMP, driving a pair of 2ways

I wish to connect a few sources, Apple TV(optical), Tuner (Optical) DVD player (Co-ax)

Can the DSP handle multiple digital inputs?

Can it switch between one Digital input (appletv) and an analogue (preamp) without having to sync with a computer?

Is there a better way of running multiple input into the board?

Thanks in advance for all the shared knowledge.

.
No problem to do source switching with a simple Break before make selector. You can read more info along with a simple diagram in the miniDIGI user manual:
- P3 for source selection
- P7 for analog/digital source

Hi, I have looked at the minidsp to use as an active 2way crossover.
I use a pc, chinese ak4396 dac and 2linn lk280 amps.
My question is does the volume control degrade the sound in any way and would it be suitable for the input impedance of 3k ohms of the linn amps.

it doesnt , ive used it for 8 weeks and it works fine. What i would advice you to do is replace the optical cable for a good rca coaxial cable to connect to the dac

This is really hard to answer (you asked: in any way...)
Theoretically there is possible degradation of the sound quality if you use a lot (say 40dB) of digital attenuation (by the way, also analog attenuation will degrade S/N / resolution), however as lduarte already said, practically it works fine and I also do not recognize any significant impact on the sound quality

Actually more important is to look at a good gain structure! In your case it may be better to use a miniDIGI to have digital input and use you DAC after the DSP (e.g. for high or low frequencies).

Quote:

output impedance will not change depending on the output level (since attenuation is done before D/A conversion) and though 3kohms is quite low I would not expect any problem (output impedance of miniDSP 2x4 kit is 560 ohms). Maybe the output impedance of the balanced version is even lower (additional Opamps at the output for balancing the signal).

@devteam: could you please clarify?

best regards, Daniel

Im looking for a decent power supply to power a newly purchase 2x8 board, with Vol-FP and Digi-FP.

As I see it there are three options, a wall wart, a switching power supply or a toriodal?

Can anyone recommend a good power supply, easily purchased in the uk.

Thanks
