SCHEMA AMPLIFIER 20 WATTS BF 2 WAY
SCHEMA AMPLIFIER 20 WATTS BF 2 WAY:
This is an amplifier that feeds a voltage of 14.4 volts, delivers a total power of 20 watts in two different channels which are connected respectively and TWEETER WOOFER.
This amplifier is therefore an active team CROSS-OVER filter with a crossover frequency of 2 kHz.
Each speaker must support a power of 10 watts and have an impedance of 4 Ohms.
The TR1 trimmer allows better rendering dosing acoustide the power of that.Release of acute channel. The supply voltage is governed way of suggestions can be between ages 12 and up get-tive 15 Volts. This amplifier peal also be advantageously used as BOOSTER 2-way car radio. In this case, it is necessary to interpose a resistance of 3.3 ohms between the output of the car radio and I'entree of the amplifier (see diagram). In order to avoid distortions of unpleasant, it is necessary to avoid "applying as input signals of top-50 mV. For mounting of components, you must follow the diagram of allenlivement implanlation.
LIST OF ELECTRONIC COMPONENTS: All resistors are 1/4 watt unless otherwise noted. R = 680 Ohms R2 = 10Kohms R3 = 1 Kohm R4 = 1 Kohm R5 = 10Ohms R6 = 10 ohms R7 = 10hm R8 = 1 Ohm TR1 = 10 Kohm trimmer CI = 5.6 nF ceramic. C2 = 5.6 nF ceramic. C3 = 2,2uF16Velec. C4 = 2,2uF16Velec. C5 = 2,2uF16Velec. C6 = 100uF16Velec. C7 = 100uF16Velec. C8 = 100uF16Velec. C9 = 100nFpol. C10 = 100nFpol. Cll-lOOnFpol. Cl 2 = 2200uF16Velec. IC1 = TDA2004-2005 1 Heat sink.
