Anyway, you did not tell me if the minidsp out of 2v is right for your amp.
What is the input sensitivity of the amp? Can it be adjusted on board (in case I want to add xlr)?
Thanks again
Oreste
g300v1 board sensitivity is 0dB(1Vrms),it can be set as other values.

Default sorry again

I got it, it can be changed. But how? Is there a trigger, a screw, on board or you have to change components on the board? Can it be changed by the user? I'm sorry, I am really interested in your amp, but I would not like to end up with something that is going to cause me troubles.
Is there a discount if I buy two?
Thanks again and again
oreste

oh! you can change some parts if you like after receive it, but 3 years warranty will loss.
you can add xlr input on it, only BAL to SE convert necessary.g300v21 provide aux power output on board.

You should really think about implementing a complete inbox solution that would be connected directed to minidsp 8 i2s/or balanced outputs/or unbalanced output and 8 output binding post on the amp..

Make your best SQ amp (like 4 lower power G300V21 in parallel) but you should think about all the voltage need and other board needed ( balanced board) etc...

see http://www.minidsp.com/forum/9-hardw...of-2x8-minidsp

this would sell like cup cakes for minidsp 2x8 users..

you could do 150w for sub + 50-75w for lowmid + 50-75w mid + 35-50w for tweets or something like that..

also if possible for like 100$ more adding an option of an 8 channel passive volume control + 2 channel passive volume for sub. (between minidsp balanced out and sinewave 8 channel amp.. ( and low cut like you did on the dac/amp etc..)

everything should be included for a perfect fit between minidsp 2x8 and bi-amp/tri-amp speakers + sub

THIS WOULD SAVE US!!! minidsp users.
Important is totally clean signal path
Please others push for this

also... bypassable tube buffer between minidsp and this incredible amp could be quite nice too

Good how much??

Any ways to have a 6channel at like 175w per channel??
With DSP would be nice too but how much is it for the dsp addon?

Are DSP FIR? if yes how much latency?

Do you have a cheaper version without DSP?

I would be interested to have this amp after a minidsp 2x8 boards using 6 output of the minidsp to this amp with 6 output of this amp to my 6 drivers.


is 2x50/2x100/2x150watt possible or something like this

6x200w or 6x150w would be good too

Oh! it is simple, you can select 3pcs g300v21 board, sound excellent when set it as 2x200w /4ohm out. three pcs enough.

we are testing our new G300STV1 now, TDA7498E 2X160W chip support.
maybe cheaper than G300v21.maybe satisfy with your requirement.
