It will flash on large instant- aneous inputs but will not pose any problems. 4) Thermal indicator When this LED is li

25、t, it indicates that the amplifier inter- nal temperature is unusually high, and the power supply voltage is reduced automatically to control the amplifier output. Consequently, you may notice some distortion when this LED is lit as the amplifier output has been reduced. 5) Crossover network circuit

26、 (AP2090, AP2130) These contain a 2 way crossover network continuously varia- ble over 30Hz 2,000Hz at an 18dB/octave slope. 6) Crossover network OUTPUT connector (HIGH, LOW; AP2090 and AP2130 only) This output connector allows multi system use with a 2 way or 3 way speaker system (Refer to Multi Sy

27、stem Examples, page 6) and HIGH PASS/LOW PASS outputs can be obtained from each output connector. 7) Compressor/limiter circuit Individual compressor / limiter circuits for each channel are contained which can be made to function by the rear panel ON / OFF selector switch. The limiter can be switche

28、d ON / OFF by the rear panel COMP / L switch. The compressor operates at a compressinon ratio of 2, from about 1/2 of rated output up to clipping output, after which the hard limiter functions to suppress distortion. Consequently, when the limiter is switched on, the output will not largely distort

29、even at ex- cess input. 4 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

30、- nector will be those set by the crossover frequency adjust- inig knobs. 2) HIGH When this position is selected, the HIGH PASS signal whose cutoff frequency is set by the (Hz) knob, is obtained at the speaker output connector. 3) LOW When set to this position, the LOW PASS signal whose cutoff frequ

31、ency is set by the (Hz) knob, is obtained at the speak- er output connector. INPUT CONNECTION Two types of connectors, XLR3-31 equivalent and 1/4 3P phone jack, both of balanced line are wired in parallel. Polarity of the pins are as follows: (#1 pin) Ground, (#2 pin) Hot, (#3 pin) Cold For the ster

32、eo mode, the rear panel MODE selector switch is set to STEREO and the left input is connected to INPUT (1) and the right input to INPUT (2). For the mono mode, the selector switch is set to MONO and the input signal is applied between ground and INPUT (1). 5 1 2 3 1 2 3 PHONE BALANCED CANNON HOT MUL

If a line transformer is to be connected, always set to HIGH PASS (crossover network selector switch to HIGH) and crossover frequency to 100Hz. T
