GT33 / GT44 / GT55 / GT57 / GT66 / GT67
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.)
