The random incidence microphones in the PianoMic system do not work like conventional
microphones. Therefore, microphone placement techniques that are used with conventional
microphones will most likely not apply when using the PM40.
Start by placing the mic heads 2-3 inches above the strings and 2-3 inches in front of the dampers.
Then listen! If you don't like what you hear, then experiment with other mic placements.
Do not excessively bend the gooseneck beyond 90 degrees. Doing so on a consistent basis will
cause the wand portion to deteriorate and lose its ability to stay in the desired position.
Do not twist the mic head more than 90° from pointing straight down at the strings.
If you encounter issues while using your Earthworks Audio microphone, please make sure that:
• The telescoping bar is secured onto the body of the piano.
• The electronics box is secure wherever you have placed it.
• The XLR connection from the telescoping bar to the eletronics box is active and strong.
• The microphone heads are positioned at an appropriate distance from the sound source.
• External noise in your recording environment is kept to a minimum.
• Your recording space is at room temperature and free of dust.
If your issue persists after checking, please contact us via our website.
