pre-amplifier

Simple preamplifier circuit:  This is a simple preamplifier circuit diagram. this diagram for the amplifier. this diagram makes sound boosted. some of the amplifier has low sound amplifiers we can use this diagram to increase the sound. this diagram runs with 12 voltages. it’s a mono pre-amplifier.    Component list …

Bass tone circuit collection: This is a Bass tone circuit collection for the amplifier. here we can get some circuit diagrams for the amplifier. every amplifier needs a sound controller. all circuits are controllers for the amplifier. some circuits need extra power some do not need power.  5 band equalizer …

Audio reverb circuit diagram: This is an audio reverb circuit diagram for the amplifier. this circuit needs an amplifier when we use the microphone. for using a microphone this circuit is important for making quality full sound. now we get this reverb to the mixer console. or we can also …

Bridge amplifier circuit: This is the Bridge amplifier circuit diagram. it’s a pre-amplifier for the amplifier. every amplifier needs a pre-amplifier. this circuit works as a pre-amplifier. here used 60-0-60 voltage. we can use 15-0-15 voltage to 100-0-100 voltage. for this, we have to change the 4k7 resistor. for 15-0-15 …

Bass tone circuit : This is the Bass tone circuit board for the audio amplifier. every amplifier needs this circuit. it’s without a preamplifier. it’s only the audio graphic to control the sound quality. we can make the sound as we want.  here, I used 3 volumes. all volumes are …

Condenser Microphone circuit: This is a Condenser Microphone circuit diagram. this diagram is a high-gain diagram. here used a condenser to make a clear sound. also, use a battery to make a high gain. A 3.7-volt battery is used here. for this, we can use this microphone to the auxiliary …

Guitar amplifier circuit board: This is a Guitar amplifier circuit board. we can use guitar input, keyboard input, and Pad input in together. this is also an audio mixer. we can balance all sound input using the separate volume. here are 3 volumes. one for the Guitar, one for the …

Easy preamplifier circuit diagram: This is the easy preamplifier circuit diagram. We use this circuit to the amplifier to increase the sound. here used one transistor. NPN transistor. 2sc1815. it’s the mono circuit. if we need stereo then we have to use dual circuit. we can use 6 voltage to …

pre amplifier for the amplifier: This is the pre-amplifier for the amplifier. this is the circuit to increase the sound. we use this circuit for the amp to get better sound. normally it is used with a bass tone circuit. here used 12 voltage. this is a mono-circuit diagram. for …

5 band equalizer circuit: This is a 5-band equalizer circuit diagram for an amplifier. every amplifier needs a good-quality bass-tone controller. we usually use volume bass and tone circuits. or bass midrange and tone. but here we use bass, semi-bass, mid, semi-treble, and treble. 5 graphic. this is without a …
