This is a

It is a excellent (famous) sub filter schematic, mod by me. Absolutely working. Ready To Solder, in
perfect
RED
PCB.
The sensitivity in auto power on mode, is about from
300
mV
.
If change the value of "
TIME ON
" capacitor (In PCB 10uF),
increase or decrease STBY
time
period
ON.
With this value (
10uF
), the
Time Stand By,
is about
2
minutes
. In the point
of relay, if you want connect SSR (Solid State Relay). For work need a small transformer (prefer toroid), 2x12VAC 5-8W.
Filter Functions:
Switch Gain x10 (single switch)
Volume (POT 100K LOG)
Gainer / Q-Boost (POT 100K LIN)
Variable 15 - 60 Hz Sub Filter (POT 100K LIN)
4th LinkWitz 60 - 300Hz (QUAD POT/2xSTEREO 100K LIN)
Less Variable Phase Control (POT 100K LIN)
The filter have
4 Pot
(3 LIN, and 1 LOG) single, and
1 QUAD
(or 2 STEREO) LIN. I put"Headers PCB"
in quad pot position, if you want to connect 2 Stereo Pot out of board
(for more flexibility)
.
