How do I make this work with DC? I 'bridge' or jumper the input terminal....but connect it to what exactly? Thanks</p>

I'd like to see a neg voltage on the op-amp so it could be used for null or used for offsetting the input. Maybe a current limiting res on the input too. Thanks.</p>

I'm a noob, how can you tell from the schematic that it is AC?</p>
