OUTST ANDING FEA TURES 1) Forced cooling When the amplifier internal temperature rises, thee cooling fan automatically changes to high speed to force cool the heat sink for protecting the amplifier . 2) Level indicator (AP2090, AP2130) This LED is lit in 5dB steps over the 0 ~ - 30dB range to check the input signal.
CROSSOVER NETWORK, SELECTOR SWITCH 1) FULL At this position, the crossover network is bypassed, (Hz) control pot becomes ineffective, a flat response output against the input signal is obtained at the output connec- tor . The crossover network outputs (HIGH, LOW) at each con- nector will be those set by the crossover frequency adjust- inig knobs.

* General use amplifiers not containing a crossover network can also be used for the low region or high region amplifier . When Ap20909/2130 are to be used as a full range amplifier , harmful sub-sonic frequencies can be cut off if the crossover network selector switch is set to HIGH and crossover frequency to 30Hz.
