Email Required, but never shown. Notice how the amplifier is used for amplifying for both recording and playback.
That’s the one I linked to – it has no circuit in it. Cheapo recorders often don’t have a potentiometer where one can set the recording level. The same tape head is also used for both functions. The application example on page 3 gives datassheet some idea. Basically, there’s an RC combination that allows you to set how fast the IC will react to varying levels of the signal. Daatsheet a major feature of this chip, and I guess it’s assumed you know what it is as you chose the chip.
What is ALC on a preamp? – Electrical Engineering Stack Exchange
Sign up using Email and Password. The ALC signal is taken from the output, via a diode and an external capacitor. ALC automatic level control was datasgeet important function in tape recorders, as the signal had to be the right level, strong enough datasheeh overcome noise but not too high to cause saturation. Post as a guest Name. I don’t see that in the datasheet I linked to above – you must have a different one.
The text next to Fig. So that looks very much like Automatic Level Control, though Audio Limiter Control is a datasyeet relative, if not exactly the same. If you look at the datasheet, there is an example application circuit: I have looked for meanings of ALC online, and I have found 2 possible meanings that would fit this device: What is ALC on a preamp?
How should I connect it?
Fancy posting a link to it? It won’t be super high-fidelity, but maybe good enough for a guitar stomp box.

If they talk all the time about ALC, and fail to explain what it is, all I can say then is that the datasheet stinks. There’s a block diagram that looks datashwet the ALC picks up the output signal and ba3038 it to adjust integrated potentiometers at the input pins of the forward path.
Don’t you just hate it when they do that?

That means it’s a peak detector, whose level is then used to control the amplifier’s amplification. It looks like the IC is intended to be used with cassette tape recorders.
