LOW IMPEDANCE CONNECTION (8 )
Connect the amplier positive output to the loudspeaker common RED wire.
Connect the amplier negative output to the loudspeaker BLACK wire.
Insulate all unused wires.
Before turning the amplier on, check connections again.
Max. power is 20 W.
Notes:
- the siNgle loudspeaker impedaNce or its total value (wheN several loudspeakers are
liNked iN series / parallel) must Not be lower thaN the amplifier output impedaNce.
- a loudspeaker total impedaNce equal to the amplifier output oNe permits to get the
maximum deliverable power (but aN higher loudspeaker impedaNce eNtails less power).
- the total loudspeaker power shall be adequate for the maximum deliverable power
of the amplifier.
- the loudspeaker liNe shall be as short as possible (for loNg distaNces, it may be
Necessary to use cables with large cross-sectioN wires).
- the impedaNce of a siNgle loudspeaker is 8 Ω; the total impedaNce of the parallel of
2 loudspeakers is 4 Ω (impedaNce = 8 / loudspeaker Number).
