parts for electromagnetic player, radio tuner, player, tape playback and line input as before preamplifier is o NE5532 integrated operational amplifier circuit assembly, having a high signal to noise ratio, low transient distortion, etc., it has a high technical performance art. Electromagnetic attenuation using a phono equalizer amplifier feedback equalization amplification clamor, because it has a high technical performance o like negative feedback phono equalizer amplifier by means of a large negative feedback loop to get the RIAA standards prescribed. The depth of the negative feedback helps reduce harmonic distortion and improve signal to noise ratio, but sometimes increases transient distortion, high fidelity make the circuit is not guaranteed. Resistive and capacitive attenuation equalizer amplifier is a resistor-capacitor network in parallel with the signal path through the attenuation network of regulatory signals to comply with prescribed standards RIAA. The disadvantage of this approach is balanced after the adoption of a balanced network, signal attenuation is large, and therefore need to increase the network after equalization amplifier stage, to make up for the loss of network signal attenuation gain. This circuit combines the characteristics of the two circuits, using an attenuated feedback phono equalizer amplifier. In the low moon paragraph (20H ~ lkH) using negative feedback in a balanced manner, due to lower this frequency and the use of an appropriate amount of negative feedback, the electric path at low frequency distortion and signal to noise ratio has greatly improved. For 1kffi- 20kHz high-frequency band by R6.C6 composed by attenuating the attenuation network to eventually meet the standards o RIAA circuit decorated by the late Choi Ilcz make a total magnification so it reaches the desired output level of 35 ~ 40dB. Line amplifier by the Ic3 and related components. It input signals, including players, tuners, phono, line input, as appropriate amplification to meet the post-amp input level required, and also the front, between the level reached after the output and input impedance reasonable match. The amount of amplification level is about 25dB. IC4, arsenic, RP3 and related components consisting of attenuated tone control circuit, high, bass control, if need sound tone control, a tone circuit I will cut through the switch carp rainbow, directly after the input signal level from the IC3 amplifier circuit. This circuit should be of high quality components assembled, resistance should use metal film resistors, Class I accuracy. Use electrical capacitance polyol content. Power should use the symmetrical power supply.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
