DIY center

From the only part that you need to buy, with the participation of old equipment it is possible to make a workable music center. The most important thing is to connect properly disparate elements, as well as protect equipment from improper use.

Materials and Tools

To build a music center you will need:

1. Cassette player.
2. Working column.
3. Power wire.
4. Shielded wire with 3.5 connector.
5. Power Supply.

Instruments:

1. Screwdriver.
2. Drill.
3. Glue.
4. Bulgarian.

The voltage of the power supply from the computer is great for assembly, +5/12 Volts. A microcircuit is connected to +5, from +12 - the battery is charged (it is necessary to buy). In the absence of electricity, the audio system can work autonomously.

The LM 7805 chip converts current into the required format. Capacitors installed for harmonic filter. Electrolytic capacitors with a breakdown voltage of 30 V, others - 55 V. The most important thing is to observe the polarity of the elements correctly. It is also not recommended to connect the chip at high voltage, as it will overheat.

Reference! It is best to make separate power toggle switches for the low-frequency amplifier, to lead the jack to the cascade of amplifiers. So you can use the amplifier box from the electric guitar. It is not forbidden to equip the system with an aux connector at the same time.

Do not forget that during operation, the low-frequency amplifier is very hot. The chip must be on an aluminum radiator of considerable size. By the same sign, the necessary element can be used from the old music center: you need to find the most loaded key.

From it go wires to the speakers. Traces on the chip can be traced with the naked eye. Now you need to determine what voltage was used in the old device in order to assemble it into the general structure:

1. Most likely, the factory equipment was designed taking into account generally accepted rules.
2. During overvoltage, this can be heard from the distortion of the sound generated by the meander. Any piece of music in this performance is similar to thrash rock, this can be easily determined by ear.
3. The element base of modern devices can support almost all signal ranges.

DIY Music Center: Step by Step

Chips make it possible to play many formats, including from a flash card. The cost of most microcircuits is in the range of 1500-2500 rubles. and comes with a D / U remote.

Attention! Amplifier microcircuits can be purchased at the store, it is possible to individually dial equalizers and other elements of the speaker system simultaneously with the adjustment knobs. This makes it possible to assemble acoustic conglomerates as needed.

Today, the possibility of using the MP 2896 embedded microsystem is being discussed. There are many others on the market. Advantage in a large assortment. The old audio system must be used properly. Today, there is no need for cassette recorders, 2 decks from the bottom are removed simultaneously with the amplifier heads and other unnecessary elements. Inside there should be a radio with a CD player. By the way, the latter can be replaced with a DVD player.

Instead of decks, you need to install several broadband speakers, this will turn out to be a boombox. Advantage in attractive appearance, ease of adjustment. The power supply is already in the design. The old music equipment did not know the USB connectors, respectively, the installation of a card reader is required. Key Features of MP 2896:

1. Power spread ± 0.30 V.
2. Power supply +5 Volt.
3. Connectors MU2F, MU3F.
4. AUX, USB input ports.
5. Board Type MW2M.
6. 4 equalizer adjustments.

There is a remote control D / U. That is, it turns out a system with a voltage of 5 Volts, reading flash drives, receiving a radio, passing sound through an equalizer. You just need to add a low-frequency amplifier and speakers to assemble a workable music center.
