I'm planning to switch my passive system to active. I need help to figure out how I'll configure it.
Here's the plan
Sources :
CD player ans Raspberry pi 3B
Crossover, preamp and DAC :
Minidsp 2x4 HD
Amplifiers:
For Tweeter : Emotiva A-100
50w @ 8 Ohms, 0,6V = 20 VRms Gain : 30,45 db.
For woofer : Emotiva A-300
150w @ 8 Ohms, 1,2V = 34,64 VRms Gain : 29,20 DB.
So 1,25 db difference.
Speakers :
Horn loaded compression driver : TAD TD-4002, sensitivity : 110db/w
Woofer : TAD TL-1603, sensitivity : 97db/W
So there's a 13 db difference.
Is it correct to say that the tweeter (horn) needs a 14,25 db (13db from divers sensitivity + 1,25db from amplifier's gain) attenuation.
If yes what's preferable :
1- Use the Emotiva A-100 volume pot to attenuate (I'll try to get the information from Emotiva to know how the volume pot works) + small adjustment with the minidsp output gain control. (I guess the A-100 volume pot needs to be set at max then turn down)
2- Do all the attenuation from the minidsp output gain control.
Master volume control done with minidsp's master volume control.
