A recessed, threaded mic stand socket is built into the OmniMouse body, next to the XLR output jack. To mount the
OmniMouse on a stand, you may find it easiest to 1) loosen the boom stand arm or threaded end of the mic stand, 2) grasp the
mic in one hand, and 3) screw the mic stand threads into the OmniMouse mount. This procedure will eliminate any possibility of
handling damage to the mic. However, we recommend always using the included shock mount to better isolate the OmniMouse
from the physical environment, greatly reducing low-frequency rumble and other undesirable environmental sounds.
The OmniMouse requires 48 volt phantom power, which is standard with most mic preamps, mixing consoles, or separate
phantom power supplies. To avoid damage to audio components when connecting phantom power, follow this simple procedure:
1) turn down the mic preamp gain, headphones, and your studio monitors, 2) connect microphone cable to the OmniMouse and
microphone input jack, 3) turn on phantom power, 4) turn up the mic preamp gain, etc. To disconnect or re-route the
OmniMouse, 1) turn down the mic preamp gain, headphones, and your studio monitors, 2) turn off phantom power and wait 10
seconds before disconnecting the mic.

This frequency chart is only a start. It gives the recordist a basis of the sound provided. How the microphone reacts in a particular application will differ greatly because of many variables. Room
acoustics, distance from sound source (proximity), tuning of the instrument and mic cabling are only a few of the interacting issues. For an artist or an engineer, how the microphones are used creates
the basis of the sound.
