The Earthworks PM40 PianoMic System uses an unconventional approach to capturing piano with superior results while keeping the microphones hidden from view. Two high-quality, random-incidence omnidirectional microphones are mounted onto a telescoping bar for close-miking within the piano itself.
The microphone capsules may be mounted to either face, or point away from the dampers. The capsules themselves feature flex-arm goosenecks that enable further microphone adjustments to be made in order to achieve desired audio results. The PianoMic connects to the 5-pin input of the electronics-box, which in turn features dual 3-pin XLR outputs for connecting to a stereo preamplifier, two mixer channel inputs, etc.
While many experienced engineers may find the close-miking technique unconventional, special technology ensures optimum results and placement inside the piano means less leakage from nearby instruments, speaker cabinets and other noise sources.
