Hello to all,
I am newbie on DSP and related stuff, hopefully somebody will find a minute to help me with this.
To save your time and this thread to be more useful to everyone else with similar issues, i made a picture, instead of looong description, of what i am trying to achieve here:
Description:
Basically i am trying to make full audio system (active speakers with amps+4 physical input channel+bluetooth streaming+remote control for that) for my home and if successful, also one for my parents and one for my sisters family.
My questions: (orange marks on picture)
(some might sound stupid, so sorry in advance, but i need to start from somewhere 🙂 really tried to crack this by my self but just stuck in a loop.
1) How should i call this, "gizmo" ?? 🙂 not sure. Input selector with bluetooth and remote control?
I tried to find something like that from miniDSP products, but got lost in that pond and got nothing certain.
I found this - input selector with remote
seems so,so at first glance, but i am not sure where to put it or does it operate alone ? or i need something like cpu for that ? really confusing here.
Maybe you know a better solution already with bluetooth receiver ?
2) Do i need two miniDSP 2X4 devices for this operation ? Or maybe other DSP device at all would be better. (for active crossovers)
I find different answer around .net, some saying it ok with one miniDSP for both speakers, with advances app,. And some say i need 2 of those, one for each speaker. Second option is x2 on budget but seems more realistic.
3) there are lots of Atp-X Bluetooth receiver modules on ebay (Bluetooth module), but how to combine those with (No.1)? and remote ?
4) so if i need two miniDSP's 2X4, i need two outputs from (no.1) device for those ?
5) what are you using for remote control of your active systems ?
6) will such relatively cheep amps work with minDSP well, as i read miniDSP only gives 0.9V signal ?
Well i hope picture above gives the idea of my vision.
Maybe someone of you made a similar or even the same config, I would be really grateful for any help!
As you might understand i am quite far from hardware electronics,
I am product designer on my day-job, scratched a surface as programmer ago and in-love with woodwork for years, but i see it not enough for this 🙂
If there is a guy (or in some miracle even a girl!) who could really help me with this project i am ok to pay some amount for you time and help. because i have much more questions 🙂))
In any case , thank you all for taking a look at my gibberish 😉
Kind regards from Lithuania,
Linas

An externally hosted image should be here but it was not working when we last tested it.

1. The term you are looking for for this box is a preamplifier with a remote control. Something along the lines of this:Yuan-Jing Burr-Brown PGA2311 Remote Digital Volume Control Preamplifier Kit with LCD Display (though the quality of this item is dubious).
2. If you just have a single stereo pair of speakers you will only need one 2x4 minidsp.
3. Doubtful you will find a remote control preamplifier board with bluetooth capabilities that meets all of your other requirements, so consider getting something with 5 inputs and having a bluetooth module separate. Just put it in the same box and power it, connect it normally.
4. Just two outputs, unbalanced left and right
5. A computer is the primary source of active systems I have built, so I can remote control it with my phone.
6. Probably will work fine, though ideally they would spec the input sensitivity. As long as it is not expecting the voltage typical of a pro system >1V
Hope this helps

Looks like most preamplifier kit boards only have 3 inputs max.
Consider a full fledged preamp with remote capabilities, along the lines of this
C 162 Stereo Preamplifier - NAD Electronics

Here is something that would fit the bill! ABBRES Audio Remote Control System
temporarily out of stock.
6 inputs though, and an LCD, you would need a phono stage infront of the phono input though, and you could use a DAC if you want the computer signal to be digital.
Looks like it could switch on and off the speakers as well if you run an extra set of wires to each one.

Speakers- putting inside the box one or two amplifiers it means that they need the power supply so a transformer >a mains cable is needed too
...but let's start from the source- using a turntable you can experience the analog sound from start to end only if you don't corrupt it with digital.
the classic turntable + preamplifier+amplifier ( or integrated one)+ speakers has no rivals. Well, only if components are state of the art ! Did I forgot...cables ?
This could apply also to other sources when they have analog outputs.
When speaking about bluetooth, the codec of transmission is itself lossy - you loose some information. Same applies to AD/DA conversion when using a MiniDSP.
Going back to speakers, the 8"+4" combos surely deserves some attention, maybe a dedicated thread🙄

I would connect everything to the computer with hight end Pro Audio AD/DA such as Apogee Symphony etc. (8 in 8 out), and do everything in the computer, including volume control, RIAA, active network and measurement. There a many extremely high quality FIR/IIR filter Eq are available for pro market for small money or free.
Mac can be controlled via iPhone, iPad or Midi controller. There are many softwares that make it possible today, and if the custom software is still needed, MAX MSP will solve everything. You have to learn a lot of things about pro audio, and no midi DSP, though...
