Bass Extender – Circuit consists of an opamp (TL074) and a few passive elements (resistor capacitor) supply voltage is 12..20 volts DC.. It is used to amplify bass sounds. The pcb drawing is very elegant, and the capacitors specified as NP in the low-cost bass booster circuit are electrolytic. type but will be non-polar RS…
You can set the outputs as analog or digital with JP1. There is a schematic prepared with splan and a pcb file prepared with sprint layout. An experimental binary sound sensor module based on an LM386 audio amplifier and an LM393 binary comparator. The sound sensor circuit is quite simple and the elements are included…
This device is a mixer that converts the stereo output of the Chapman Stick to mono. The bar has one stereo output, so you must use a dual-input amplifier or use two amplifiers. A two-input amplifier is expensive, and having two amplifiers is a hurdle. Using this device, you can use most commercially available mono-only…
The ComBox is a practical accessory for LAN parties, network or other occasions when a group of computer users to communicate between rooms meheren. It is a pure hardware structure, unlike the case for this massive scale already available software solutions A number of advantages: # runs on any operating system, independent of software depending…
summarizes examples of a circuit that can change the sound effect on audio file will give more or less the idea of a device called circuit Okita vocoder clone .. Voice coder circuit are all sources of PCBs, drawings, bill of materials .. Circuit diagram consists of three sections headphone amp section is a quality…
High-quality low-frequency chain is relatively very expensive and thus no wonder that they are trying to protect its individual components in every possible way against damage or even destruction of improper manipulation or random problems. One of the possible failures are punctures one of the terminal transistors power amplifiers or any other cause, leading to…
There are various simple, easy-made guitar effects circuit diagram pcb completed and completed the majority of applications, especially in cases where there’s photos simple wiring diagrams makes your job easier;) Range Treble Booster guitar effects Just as his role model is minimalist, and he works with a PNP germanium transistor. As a contrast to his…
