Professional Stereo Preamplifier Circuit

A lot of professional preamplifier circuit that hosts the volume control bass, treble, medium, balance, mute, loudness (low bass tones reinforcing) and volume control settings can be made. Professional Preamplifier NE5532 op amp circuits used in the two units working voltage + -15 symmetrical drawing pcb’s regular and all materials on the market. Pa7000 preamplifier

18Hz-200Hz Active Subwoofer filter circuit NE5532

Active Subwoofer filter circuit based on the frequency between 18 Hz 200 Hz ne5532 op ampar setting. Subwoofer Filter circuit power supply 15v dc rectifier +-7815, gathered on a single pcb pcb li regulator 7915 times the design of very high quality material, the placement of entrances, exits, etc. on a regular circuit pcb layout

Microphone Input 4 Channel Mixer Amplified Circuit

Mixer circuit 2 x microphone input and audio input 4. It’s a good thing the printed circuit layout easier to use with the optional sürügülü potentiometers normal potentiometer can also be used, but in this case is made or additional cable with additional pcb is prepared. Mixer circuit direct op amp can be connected to

Distortion Pedal Clone Circuit Box of Rock

Guitarists use of the mesh a pedal model Box of Rock circuit gain, tone, volume, boost control’s bs170 MOSFET and passive components based on the noise ratio is very low absolute best performance to get the 9v battery should be fed resistors metal film 1% tolerance should be Box of Rock distortion pedals have all

20Led Stereo VU Meter Circuit KA2281

Previously KA2281 20 LED mono VU Meter to the circuit I shared the stereo version also am sharing this circuit 2 ka2281 used pcb printed circuit board dimensions mono version of the same operating voltage 12v dc R – L audio input located on the knob with LED combustion can adjust the level printed circuit

Speaker Delayed DC Protection Circuits

Usually the amplifier is shorted output transistors, DC, power failures, this situation gives reliable, though valid in the lecture but integrated requirements may vary according to the situation of failure. It makes more sense to add additional circuitry to protect the loudspeaker DC-protection circuits to detect and relay the DC output of the power amplifier

10 LED VU Meter Circuit LM3915

In this article made ​​with LM3915 integrated LED vu meter is shown in Figure 10 . VU meter circuit feature , listened to music according to the severity of the LEDs are lit . So vu meter circuit indicates the level of severity of music . Music of the bass, treble and volume regardless of

Voice Changer Circuit Donald Duck Sound

The use of voice-changing circuit will sound interesting and fun changing the tests gives the circuit except for the passive elements in shades of Danılt Min ca3240 (bimos op amp) and the tl072 (jfet input opamp) based on clean and effect by setting the potansiyometreleri op evening sound is being changed. The circuit can be

Guitar Effects Emulation Circuit Marshall
