Connecting to a line level output (tuner, preamplifier, cd player… ) and connecting a power supply
from 12 to 15VDC / 300mA max..
Connect the unit to a suitable supply voltage between 12VDC and 15VDC, this can also be a standard DC
adapter. You can also build your own power supply, see diagram. Use a 2x12V transformer, two rectifier
diodes and a electrolytic capacitor or use a single 12V transformer with a bridge rectifier and a electrolytic
capacitor.
