Subwoofer combinations
All passive subwoofers with minimum impedance of 2 ohms can be driven. The A-409 has
exeptionally strong deep bass power and must be adjusted to the power rating of the subwoofer.
Subwoofer connection with these steps
1. POWER at OFF, all knobs far left.
2. LOW INPUT connect as sketches A to G. B is useful if the Subwoofer input signal is too low.
C is requested if SAT OUT = Satellite output signal is needed. At F and G the level is only
adjustable at A-409.
