Recording an uber-critical track? Need to ensure beyond a shadow of a doubt that it does not clip? Here’s a trick used by many location/remote recording engineers who only get one shot at capturing a perfect take: record the signal to two tracks. Set one at a level that is appropriate for the signal you are working with. Then, as a safety, route the signal to a second track and pad the level down by 10, 15, or even 20dB.
