User manual M-AUDIO 1B-FET MICROPHONE

[. . . ] Never attempt to change the tube on the GT 44, GT66 or GT67 or Model 1B. Please contact technical support if this is necessary. 3. Make sure that the PSM1 power supply is turned off. Connect the mic to the PSM1 power supply using the included 25-foot, 6-pin cable. [. . . ] It's great for vocal groups, Foley sound effects, and realistic acoustic instruments. Omni is also less sensitive to the proximity of a vocalist to the microphone. · Figure 8 The figure-8, or bidirectional, pattern is excellent for capturing a duet or interview with a single mic. The ­40dB side rejection spec also makes it great for isolating an instrument like a snare from the rest of a drum kit. Figure 8 is also one of the key components to M/S (mid-side) miking--a technique for recording stereo that many pros utilize exclusively. (Continued on reverse. . . ) Connections and Phantom Power Groove Tubes microphones output a balanced, low impedance signal. As such they require the additional signal boost gained from connection to mic-level inputs of a preamp or mixer channel. As with all condenser microphones, your Groove Tubes condenser requires power in order to operate. GT33 / 55 / 57 / Model 1B-FET If you have a GT33, GT55, GT57 or Model 1B-FET, you will need to connect the mic via XLR to a preamp or mixer channel strip that supplies +48-volt phantom power. (Phantom power shares the same XLR cable as the audio from the microphone). In order to avoid loud pops that can damage components like speakers and microphones, always perform the following in the order presented: 1. Turn the gain on your preamp and/or mixer down. Make sure that phantom power is disengaged. Connect the microphone via a high-quality XLR cable. Turn up the gain on your preamp and/or mixer. Reverse this procedure when disconnecting the microphone. GT44 / 66 / 67 / Model 1B If you have a GT44, GT66, GT67 or Model 1B, the included PSM1 power supply provides the required power to the microphone. (While no external phantom power is required, the presence of phantom power will not harm the microphone or power supply. ) In order to avoid loud pops that can damage components like speakers and microphones, always perform the following in the order presented: 1. [. . . ] Screw the new capsule in, then screw the top of the microphone body back in place. Sensitivity Pad All Groove Tubes microphones, except the Model 1B and Model 1B-FET, feature a switch to engage a pad which reduces the sensitivity of the mic (-10dB on the GT 55, GT57, GT66 and GT67, and -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 closemiked guitar amps or kick drums. Engage this switch when you must set your preamp input unreasonably low and/or hear distortion. Otherwise, it is recommended that the pad remain disengaged in order to benefit from the best signal-to-noise ratio. Roll-off Filter All Groove Tubes microphones, except the Model 1B and Model 1B-FET, feature a switch to roll off frequencies below 75Hz. [. . . ]
