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.

Other methods are relays that connect the audio, so then you have contact resistance in series – not usually a problem, but many purists will not be happy with this. For example, a 12V relay has a coil resistance of Ohms, and the unregulated supply voltage is 21V DC How to work out the resistor value? Please enter a number less than or equal to 5.


In the meantime, it can be made reasonably easily on Veroboard or a similar prototyping board. Watch list is full.

The size of the board is such that it can be tucked away in any convenient location, and the relays would normally be physically located as close to the output connectors as possible.

Contact the seller – opens in a new window 74c9914 tab and request a postage method to your location. 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. Keeping the supply to 5.

Delivery times may vary, especially during peak periods. When the threshold voltage of U1B is reached, dagasheet output goes low immediately, discharges C2 via D4, and turns off the relay.

To calculate R6, use the same formulae as shown above, but use 12V instead of 5. Please enter a valid postcode. Even if the CMOS supply is not well regulated, the circuit will still work fine – the zener is required though, as any datzsheet voltage however brief may damage the IC.
