How to installing tone control on the amplifier unit.

Assalamu'alaikum warohmatullohi wabarokatuh.

Let us talk about the installation or extension AMPLI tone control on our own or amplifier assemblies. Tone control or regulator tone is one of the principal of a power amplifier unit. If no tone control that can not be said of the amplifier, so it can be said as a condition of tone control AMPLI syahnya. Maybe so or What about yaa? This time Maswar Service not specifically discuss a particular tone control, but in general the tone control and how extension. No tone control using the active component in the form of IC is also the use of transistors and they can all be used. There is a need tension - and + wherever there was a need symmetric voltage (-, + and 0) and we adjust the voltage source according to the load demand.

During amplifier with a small force with power working voltage of 12 volts, the voltage of the tone control can diambilkan the same power suply, but if considerable force and power working voltage greater than the voltage amplifier tone control work then need its own power suply or regulators to tone controlnya. As an example of the power amplifier voltage 35 volt wear while working voltage of 12 volts then the tone control can be added to IC 7812 obtained a stable voltage of 12 volts to mensuply tone control.

Connecting the output tone control.

The out put terminal of the tone control is connected to the input of the power amplifier. If possible paste the tone control PCB with PCB power, or make it extension cable as short as possible. It is intended to reduce the effects of the amplifier so buzzing after. If the tone control and power are equally mono or stereo, it was clear to stay connect. But if not the same, for example controlnya mono tone while powernya stereo, then the mono output can install a resistor 2K2 dicabangkan two went into the power input. The value of R is not absolute and can be tailored to their needs.

Connecting input.

Point tone control input connected to the RCA socket if there is no additional network. But if any such additional or other galaxies, then the tone control input connected to the output of the previous network. Installation on the box. If the hole where the distance fits potensio potensio meter layout in PCB can then directly inserted without using cables, but if it is not appropriate and should be put on the cable using the cable skerm and do not run too long. Position the PCB around two centimeters above the box bottom and if possible put a bit away from the transformer. Once installed, the potentiometer is connected to the body between a cable box and digroundkan the body. It is not intended to create buzz too, which is very classical in AMPLI assemblies. Such postings could Maswar service for on this occasion, may be beneficial.
