Rangkaian 10 led ini function to indicate the height level of sound, which in the show led with a flame Supply voltage is needed in the series is 3V to 20V. 10 led work if audio voltage into a series of valuable 1.3 volt

Rangkaian 10 Led Sound Meter using the IC LM3915N which can control up to 10 LED. There are 10 fruit komparator that compares the input voltage level of the voltage reference (pin 6). In the IC has a reference voltage source is available so that you no longer need a reference voltage source from the outside.

To increase the voltage reference can be done with installing resistor R1 and R2 (picture 1). Voltage reference that has been raised is not sensitive to changes in temperature and voltage portion. Reference voltage is used to control the voltage divider in the IC

Signal input (audio signal) should be first in the right direction, just half a wave, then enter pin 5. Signal input into the face of the brace by TR-1. Voltage that has been and is supported by a series of buffer TR-2. Output signal is taken from emiter TR-2 and a half in the direction the waves by D11, and filtered by R6, C4, and R8.

The level of input made by trimpot P1. 8-pin in the ground, so the reference voltage on pin 8 output of 1.25 volt (minimum) references provided in the high (pin 6). So that the flow out of the pin 7 is big enough to light a LED, then R9 is made quite small (390 ohm). Installation of C6 to prevent oscillation arising due to voltage LED is not filtered. S1 is a switch for selection of "fast" or "slow.

Power is a 3 Volt battery, but the IC will work with any voltage between 2.5 - 5 Volts. Switch S1 is the on / off switch. The output at pin 10 is amplified and drives a small 8 ohm loudspeaker. Pressing S3 once will generate all the sounds, one after another. S2 can be used to produce a single sound effect, next depression gives the next sound effect. Standby current is about 1 uA at 3 Volt, so battery life is very economical.

Rangkaian Power Amplifier Sound System 2000 Watt

type='html'>

This power amplifier circuit provides up to 2000Watt, it has to be said that this amplifier will blow up any speaker connected to it. I recommend this as a 'thought experiment', rather than actually doing it!. 110V RMS into 8 ohms is 1500 W. How long would you expect the speaker to last? Most will be toast within perhaps 30 seconds or less!

The transistor Q5 (the bias servo transistor) is mounted on the heatsink, in excellent thermal contact. This is because, unlike most of my other designs, this amp uses conventional Darlington output configuration. It is necessary to use a Darlington arrangement (or a low power Darlington transistor as shown) for Q5 to ensure that the bias remains at a safe value with temperature. There is probably good cause to model and test this aspect of the design very carefully, because it is so important. The arrangement as shown will reduce quiescent current at elevated temperatures. For example, if total Iq at 24°C is 165mA, this will fall to ~40mA at 70°C. This is probably fine, because there is some delay between the a power 'surge' and the output transistors transferring their heat to the bias servo via the heatsink.

The power supply needed for an amp of this size is massive. Grown welding machines will look at it and cry. For intermittent operation, you need a minimum of a 1000VA transformer (or 1500VA for the 2000W version), and it will have to be custom made because of the voltages used. If you expect to run the amp at continuous high power, then transformers should be 2kVA and 3000VA respectively. Filter capacitors will pose a problem - because you need caps rated for 150V, these will be hard to find. Because high voltage high value caps can be difficult to find, it may be necessary to use two electros in series for each capacitor location. This is the arrangement shown. You must include the resistors in parallel - these equalise the voltage across each capacitor so that they have the same voltage. Remember to verify the ripple current rating! This can be expected to be over 10A, and under-rated capacitors will blow up.

Sound Level (Decibel) Meter Circuit

type='html'>

This is a decibel meter electronic circuit, For an audio engineer, this circuit seems to be very helpful, especially for checking of sound pressure levels from about 60 to 70 Decibel (dB). EACH light represents about a 3dB change in sound level so That Pls all three lights are on, the sound level is about 4 times Greater than the level needed to light one lamp. The sensitivity cans be adjusted with the 500K pot so That one lamp comes on with a reference sound level. The other two lamps will from then indicate about a 2X and 4X increase is in volume.

Circuit of Sound Level (Decibel) Meter

In operation, with no input, the DC voltage at pins 1,2 and 3 of the op-amp will be about 4 volts, and the voltage on the (+) inputs to the 3 comparators (pins 5,10,12) will be about a half volt less due to the 1N914 diode drop. The voltage on the (-) comparator inputs will be around 5.1 and 6.5 which is set by the 560 and 750 ohm resistors.

When an audio signal is present, the 10uF capacitor connected to the diode will charge toward the peak audio level at the op-amp output at pin 1. As the volume increases, the DC voltage on the capacitor and also (+) comparator inputs will increase and the lamp will turn on when the (+) input goes above the (-) input. As the volume decreases, the capacitor discharges through the parallel 100K resistor and the lamps go out. You can change the response time with a larger or smaller capacitor.
