SWITCH SETTINGS (Fig. 2)
9 Gain Setting
Set the KTA-200M input gain to the minimum position. Using a dynamic CD as a source,
increase the head unit volume until the output distorts. Then, reduce the volume 1 step (or
until the output is no longer distorted).
Now, increase the amplier gain until the sound from the subwoofer becomes distorted. Reduce
the gain slightly so the sound is no longer distorted to achieve the optimum gain setting.
