Just finished designing PCB for Active Bi-amp.
Features
1) LM3886 x 2 for Woofer (68W x 2)
2) LM1876 x 1 for Tweeter (20W x 2)
3) 2 x dual Regulated Power supply using LM338 and MUR860 ultra fast diodes to power 1 x LM1876 and 2 x LM3886
4) Speaker protection and delay using Relays
5) Preamp using NE5532
6) 2 way 24DB/octave LR active filter using NE5532
7) Provision for mounting stereo potentiometer for volume control on the board.
8) separate regulated power supply using LM7815 and LM7915 for active filter.
In process or ordering components for this, Will share component selection details later.
