The High Pass Filter is a low frequency cutoff setting, which you
can use to remove rumble, motor noise or other low frequency
noise while recording. It will affect the tone slightly but in some
situations it is required.
For instance, it may be helpful to engage the High Pass Filter to
cut out the sound of air conditioning, handling noise while adjusting
focus settings and distant traffic audible in the background.
You will find that older model and low cost cameras produce more
motor noise, which the VideoMic Pro can pick up. Using the High
Pass Filter setting is also ideal for reducing this.
To engage the High Pass Filter, slide the power switch to the
right hand position until it is pointing to the HPF symbol (
).
