Skema Rangkaian Amplifier OCL 20 Watt Hi-Fi dengan Transistor. 2 October, 2018 Rangkaian Amplifier. Rangkaian Amplifier OTL 15. Untuk membuat rangkaian power amplifier tidak memerlukan banyak komponen eksternal, karena power amplifier ini hanya menggunakan sistem power supply otomatis. Gambar Skema Rangkaian Power Amplifier. Power Amplifier merupakan penguat akhir bagian sistem tata suara yang dapat berfungsi sebagai penguat sinyal audio yang pada dasarnya merupakan.
The stereo signals coming from the line outputs of the car radio amplifier are mixed at the input and, after the Level Control, the signal enters the buffer IC1A and can be phase reversed by means of SW1. This control can be useful to allow the subwoofer to be in phase with the loudspeakers of the existing car radio. Then, a 12dB/octave variable frequency Low Pass filter built around IC1B, Q1 and related components follows, allowing to adjust precisely the low pass frequency from 70 to 150Hz.

Q2, R17 and C9 form a simple dc voltage stabilizer for the input and filter circuitry, useful to avoid positive rail interaction from the power amplifier to low level sections.
It is perfectly ok to have “non 5Vs” coming out of a 5V regulator. All your voltages should be referenced to a common point. Having it as you show it, even if you are copping others, IS confusing. The regulator is just a component, not the final design.
By the argument you put forward, any variable power supply that uses, for example, a LM317 regulator would have a 1.25V output all the time as it is a 1.25V voltage regulator. The LM317 is just a part of a circuit that happens to be a 1.25V regulator, but produces a variable output.
The same way the regulators in this circuit are being used to produce “non 5V” power rails. They are just used to get a power rail that is offset by 5V from another rail. But all rails are measured W.R.T. I wouldn’t go lower than 20-24V for the power supply,but at least 30V is recommended.
For low power amplifier, I think a different design would be better. If you are using a transformer (I recommend toroidal because of their size), and not a SMPS, you will need a bridge rectifier and some beefy filtering caps (I personally used 2x10 000uF per branch - positive/negative).
About the potentiometer, although you could add one before the ” Input -P1” of value 100K, I suggest building a pre-amp circuit that also has tone control. It is +12V referenced to -30V. Imagine that we use a multimeter and we put the black probe (ground) to the -30V rail. If we measure the real ground (which is 0V), on the multimeter digit we would read +30V.
