A pad on a microphone is a switch or setting designed to reduce the strength of the incoming audio signal by a fixed amount, typically measured in decibels (dB). This feature is also referred to as pre-attenuation or a passive attenuation device (PAD). Its primary purpose is to prevent clipping and distortion that can occur when a microphone is exposed to very loud sound sources. Both the microphone's internal electronics and the connected preamplifier have a maximum signal level they can handle before distorting. By engaging the pad, the signal level is lowered *before* it reaches these sensitive components, ensuring a clean recording. Common pad values found on microphones and preamps include -10 dB, -20 dB, or sometimes -5 dB. Here are the key aspects of a microphone pad:
- 1.Preventing Distortion
- 2.Increasing Headroom
- 3.Placement
- 4.Avoid engaging a pad unnecessarily, as it reduces the signal-to-noise ratio. Only use it when clipping or distortion is present due to an overly hot signal.
