Buildguide
nothing special.. just install the parts.. and solder everything
before you start:
the C1 100uF capactitor is optional - jumper the pins as seen in the above picture.
...
make sure you install in C2 and C10 the BIPOLAR electrolyte caps (C8 and C9 is polarity sensible)
Pinout:
pin number | function |
---|---|
-V | negative Power input from -12V thru -18V |
+V | positive Power input from 12- 18V |
AIN | analog unbalanced input from your audio source |
GND pads | ground for voltage (one pad with ground is fine) in some devices you have to ground the chassis with the GND pads too (in case you have hum issues from the circuit, but make sure you don't have a ground loop) |
TRS header balanced output !! | T = Tip R= Ring S= Ground/sleeve |
