When powering up for the 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.

Figure 1 – Muting Circuit Connections. Being sealed from the outside atmosphere, there is nothing to tarnish the contacts. Postage Discounts for combined Orders.

It goes without saying that a PCB makes it very easy to assemble and very hard to make a mistake. Without it, the relay state will be indeterminate at power-on if nothing is connected to the AC terminal.

In many cases, a small signal transistor may also be used for Q2, provided the relay current is within the transistor’s maximum current datasgeet typically only mA or so. R8 is easily dataxheet, based on the relay coil resistance and the measured supply voltage. Base current into Q1 will only be in the order of a couple of milliamps. Delivery times may vary, especially during peak periods.

It is also very important to keep the relay coil wiring as far removed as possible from the audio signal leads. Provided the applied voltage is maintained, C2 charges up via R3 until the input threshold of U1C is reached.
