Impedance Matching:
KAD-2 is capable of 4-16Ω impedance output if more than one speaker is to be connected to the amplifier
per channel. Please ensure the total impedance of the speakers are within the range.
Speakers can be wired in two different ways, in parallel or in series. The total impedance can be worked
out by the following formulas for the two different ways of wiring:
Parallel Connection - 1/Rtotal = 1/R1+ 1/R2+ 1/R3…….
