A recessed, threaded mic stand socket is built into the OmniMouse body, next to the XLR output jack. To mount the OmniMouse ona 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

handlingdamage to the mic. However, we recommend always using the included shock mount to better isolate the OmniMouse from thephysical 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 powersupplies. 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

secondsbefore disconnecting the mic.

This frequency20chart 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.
