Any recording or live sound engineer will tell you that conventional microphones do 

a poor job inside a piano with the lid closed.  Sound engineers were amazed when 

they heard the exceptional sound quality of the PianoMic™ System used inside a 

piano with the lid open and at half-stick. But they were absolutely floored upon hear-

ing the fantastic performance with the lid closed.
When using a PianoMic™ System for live performance you will achieve the most 

gain before feedback with the piano lid fully closed. You will also have the least 

amount of leakage from sounds outside the piano with the piano lid closed.
We know you will be more than pleased with the performance of the PianoMic™ 

System for both recording and live sound applications.

SETTING UP THE PIANOMIC™

The PianoMic™ System is quick and easy to install. Once you have initially set up 

the PianoMic™ System you will be able to do it from that point on in just a few 

minutes. Here are some helpful guidelines:
CAUTION – the microphone heads and goosenecks are permanently attached 

to the center section of the PianoMic™ telescoping tube and cannot be moved, 

or removed. The distance between the two goosenecks is fixed at 16 inches (one-

third of the width of a piano keyboard). 
1.  Check that all items are included with your PianoMic™ System by using the list 

of “Items Enclosed” on the first page of this manual.
2.  Remove  the  PianoMic™  telescop-

ing bar from the case and loosen the two 

clutches on either side of the two micro-

phone goosenecks (See Figure 3). When 

adjusting the clutches, be sure to hold the 

larger diameter tube section with one hand 

while rotating the clutch with the other 

hand  as  indicated  in  figure  3. However, 

do not loosen the clutches all the way; just 

enough so the bar can be extended and still 

have a little friction. This will make it eas-

ier to adjust the length of the bar from both 

ends once it is placed inside the piano.

3.  Extend both sides of the bar so that it is wider than the piano.  
4.  Notice that on each end of the PianoMic™ bar there are support brackets that 

will be placed on the upper edge of the piano case sides. These support brackets 

have rounded edges and are covered with a soft coating to avoid scratching the 

piano. The support brackets are thin enough to allow the piano lid to be completely 

closed with the PianoMic™ System inside the piano. If you desire a more snug fit 

with the lid closed or if vibration becomes an issue, install one of the enclosed felt 

pads on the support brackets as shown in Figure 4. If this is not a snug fit, you can 

place additional felt pads on top of the support arms as well.
