His involvement This circuit can with a minimum of external components to change the volume, balance, treble and bass.

TDA1524 TDA1524A DIP-18 Stereo-tone volume control circuit NEW

The parameters declared by tra1524 manufacturer will be listed and compared. This source must be powerful enough to be able to cover the power demands of the terminal degree. This should no longer be a problem. Sabre II Bass Preamp. Another advantage is that the circuit is not prone to the murmur of the potentiometers, which manifests itself e.

Current sensing is used to provide a flat response when R5 is connected to pin 17, and a loudness contour when disconnected. Catalog wiring taken is followed by the dc link, which improves the control signal. C15, 16, 17 provide power supply filtering. Tda15524 sure you test the voltage first in all cases.


If you are not using a switch pot, you can connect an external switch across the P1 switch pins, or connect a wire link there and switch the power supply. C5 and C6 control the treble turn-over frequency. The source can be realized as linear, or as a source of power.

Low volume settings coupled with treble boost was causing HF instability in some instances. The smps power supply of the amplifier, as is indicated must have a few output voltages. Replace D1 with a wire link if necessary, making sure you have the supply polarity correct! R1 and R2, are to ensure stability with capacitive loads. Name Email Comment Or tdz1524 this link or this one. This site dta1524 cookies: The current drain of the pre-amp is less than 50 mA, so many 12 Rda1524 unregulated supplies tda154 be adequate if you have one.

Its advantage is that all settings adjustment is performed by changing the voltage on the corresponding pins of the circuit and that for both channels at the same time. Preamp circuit is TDA from the company Philips.

All signal processing is done within the TDAA by voltage controlled amplifiers and voltage controlled filters. R3 and R4 make sure there are no DC spikes at the output sockets if the load is switched.

The LED is a power on indicator and may be omitted if not required, or preferably mounted on the enclosure.

Application was restored thanks to www. However the regulator will not be necessary with a battery supply.

Because most plug packs have poor regulation, one rated at 12V DC will often be around 15V when lightly loaded. If you wish to use it with a car or other 12V battery, then you should omit the regulator, and place a wire link between the regulator input and output pin positions on the PC board.

Or visit this link or this one. If you are using a V supply for your power amplifier, you can use that as your pre-amp supply as well. C3 and C4 control the loudness contour. Each of these types of sources has its advantages and disadvantages. An on board regulator is provided to reduce mains hum. Its advantage is that all settings adjustment Do not short to earth!

Thanks to this, it is not necessary to use high-quality tandem potentiometers, which are expensive, but just simple potentiometers. This is a low noise and distortion pre-amplifier and tone control circuit in one module.
