Sensitivity Pad
All Groove Tubes microphones feature a switch which can be used to engage a pad, reducing the sensitivity of the mic (-10dB on the GT 55, GT57, GT66 and GT67; -15dB on the GT33 and GT44). These are useful to prevent overloading the microphone electronics or your preamp when recording an extremely loud sound source such as when close-miking guitar amps or kick drums. Engage this switch when you find you are having to set your preamp input unreasonably low and/or are hearing distortion. Otherwise, it is recommended that the pad remain disengaged in order to benefit from the highest signal-to-noise ratio.
Roll-off Filter
All Groove Tubes microphones feature a switch to roll off frequencies below 75Hz. This is useful in reducing or eliminating low frequency noise such as floor rumbles, mic stand noise, passing trucks, etc.. It can also be used to help eliminate the proximity effect present when using cardioid patterns. (The proximity effect describes the phenomenon of an increased bass emphasis or �boomy� sound quality as the sound source gets closer to the microphone.)
