When powering up for datasheett first time, you can use a ohm to ohm ‘safety’ resistor in series with the DC supply to limit the current – this will save damage if you have made a mistake in the wiring.

C Logic IC Function: Resume making your offerif the page does not update immediately. This amount is subject to change until you make payment. This is covered below. Add to Watch list Watching. To ensure that U1A actually switches, the AC terminal should is returned to earth ground via a resistor R7 – this is only needed for testing but does no harm if permanently connected.

This places datasbeet short across the audio signal and mutes the signal.

Watch list is full. Provided AC is present, the output of U1A pulses low 50 or 60 times per second, and via D3, keeps the voltage on C1 below the trigger threshold of U1B. Learn more – opens in new window or tab.

In many cases, a small signal transistor may also be used for Q2, provided the relay current is within the transistor’s maximum current rating typically only mA or so. The relay itself should be a miniature DPDT double-pole, double-throw type, and suitable units are available from all major suppliers. There are 5 items dstasheet. In the meantime, it can be made reasonably easily on Veroboard or a similar prototyping board.

There are several ways this may be done, but the simplest and least intrusive to the audio signal path is to use relays that short the outputs of the preamp, crossover or other circuit.
