MXL FR-310 Specifications

Note: Your recording device may have internal gain controls that may
need to be adjusted to get the best results. Consult your device's user
manual for more information.
Switch #2 has three positions, which are labeled "Off," "On" and "Roll-off."
When this switch is in the "Off" position, the microphone is off and will not
draw power from the battery. The "On" position turns the microphone on
and sets it to record with no filtering. The "Roll-off" position sends the
signal through the microphone's high-pass filter to reduce or eliminate
low-frequency noise. For example, older camcorders sometimes
produce low-frequency motor noise. The high-pass filter will reduce or
eliminate this noise.
