An excellent multipurpose instrument mic with an interchangeable capsule.

The Audix f9 small-diaphragm condenser mic is known for its clear, accurate response-particularly in the upper-frequency range. Ideally suited for a wide variety of acoustic instruments, the Audix f9 mic is an excellent choice for cymbals, overhead, percussion table, and ambient room miking.

With a uniformly controlled cardioid polar pattern, the Audix f9 microphone captures instrument acoustics and at the same time isolates their sounds from the rest of the instruments on stage. The Audix f9 is equipped with a 16mm pre-polarized capsule with a gold vapor diaphragm and a frequency response of 40Hz-20kHz.

The Audix f9 is ultra easy to position, durable, and manufactured with high standards and tight tolerances. Its roadworthy construction includes a precision-cast zinc-alloy body, black finish, laser-etched model number, steel mesh grill, gold XLR connector, and a tension-fit heavy-duty nylon mic clip.

User tips:
The f9, an excellent choice to mic any kind of acoustic instrument. It has a cardioid pick-up pattern, which helps to eliminate sound from other instruments on stage from bleeding into the microphone. However, the f9 is much more sensitive than a dynamic and will pick-up sound from a greater distance. The acoustic nature of the instrument being miked, along with how loud it is, will determine how far the microphone should be from the sound source. For example, the f9 can be placed 1 - 2 feet above the cymbals of a drum kit and still pick up plenty of sound, whereas for a acoustic guitar, the mic will need to be placed within 8 - 12 inches to be effective. Allow a distance of 2-3 feet between microphones to avoid phase issues.

Phantom power operation:
The f9 will NOT operate without phantom power. The f9 requires 12-48V phantom power, which is available on most professional mic preamps and mixing devices. If phantom power is not available on your equipment, you will have to purchase a phantom power supply (such as the Nady SMPS #180162, or ART Phantom I #180266) ). Avoid plugging or unplugging the microphone from a PA system unless the channel is muted or the volume of the system is turned down. Failure to do so may result in a loud popping noise, which could seriously damage the speakers in the PA system.

    Comments about Audix F9 Small Diaphragm Condenser Microphone:

    These mics do have a slight internal noise , but not if your using them live and if you are then who cares because you will not hear it over any other part of live amps etc ,if your using these in a studio application with a clean board , you will need to watch your gain structure , i own about 40 mics but lets stick with the small condenser mics , a shure sm 81 is quieter it has full 20 20 that is flat , and no character ,but is open for as much character you want to instill in them i.e. tube preamp ,clean pre amp boast a freg some were in your chain etc , these mics do not cover that freg , and they have 8hz boast in them , but wait ... i have not found any faults with this mic and acoustic guitars just wow , classical guitarist fall in love , stereo pair on a steel string is just simply marvelous , especially a finger style artist , bring them close don't over due your gain , or listen in the head phones when you hear them with out any outside noise , then position !! you can bring your gain up in your compressor or on the channel gain with out more noise introduced , yes we did a test on hese with several engineers blind tested over the shure sm 81 it won hands down with all of us on ..acoustic guitar

    Comments about Audix F9 Small Diaphragm Condenser Microphone:

    Stay away from these mics. No matter what i did they Produced a very audible hiss. When sources are alone you can definitely hear it but when in the mix its more difficult. I used them in an XY config on a Harp and the recordings were unusable. (Preamp settings made zero difference) I Had to switch to a different mic. I gave them two stars instead of one because they don't sound terrible aside from the hiss and are usable when mixed in a full band scenario. The value of these mics are very poor.
