External Microphone

Item #: 170172


The ATR1100x handheld microphone is tuned for clear audio reproduction. The mic’s unidirectional polar pattern focuses pickup on the sound source and protects against feedback, making the ATR1100x a fine, all-purpose mic for use when tuning acoustic instruments. Featuring an on/off switch and a permanently attached 3 m (9.8') cable with a 3.5 mm (1/8") mini-plug. The ATR1100x is a great choice for use with any Peterson tuner that features a ¼” input to provide added directionality control of incoming signals. The mic comes with a desk stand and a 6.3 mm (1/4") adapter.

The directionality of this microphone is good and I'm able to tune a piano is a non-perfectly quiet environment, but the microphone stand/holder is pure junk (it won't support the microphone) and the listed frequency range of this microphone is only 80-12,000. The lowest note on a piano is 27.5, which is below this mic's range. When tuning those lower frequency keys, I suppose the strobe is registering only the harmonics.
