6. Once you have determined which placement will provide you with the abil-
ity to have the microphone heads two to three inches in front of the dampers,
you are ready to place the PianoMic™ System inside the piano. With the bar
fully extended and the clutch adjusted where there is still a little friction, place
the support bracket on the edge of the piano case opposite you. Then push on
the bar until the PianoMic™ is the correct length to allow the support bracket
to easily rest on the edge of the piano case nearest to you.
7. With the PianoMic™ in place, you will need to determine if you want the
microphones to favor the high strings, low strings or neither. The center sec-
tion of the PianoMic™ can slide up to eight inches in either direction in order
to favor the high or low strings, if desired. This positioning is illustrated in
Figures 9 and 10.
8. Once you have positioned the PianoMic™ center section, tighten both clutches
to insure that the PianoMic™ bar stays in place.
9. With the PianoMic™ in place, you can move the flex arms attached to the mi-
crophone heads several inches to the left or to the right to achieve your desired
placement (See Figure 11).
10. The flex arms also allow you to adjust the height of the microphone heads as
shown in Figure 12. It is suggested that you place the microphone heads two to
three inches above the piano strings.

4. The PianoMic™ can be placed inside the piano with the microphone heads either
facing the dampers (Figure 6) or facing away from the dampers (Figure 7). For opti-
mum results, the PianoMic™ System should be placed in the piano with the micro-
phone heads positioned two to three inches away from the dampers. How you place
the PianoMic™ System in the piano will depend upon the piano, its size and how it is
made. This will govern whether the microphone heads can be faced toward or faced
away from the dampers. It is best to position the PianoMic™ System so that the sup-
port bracket does not rest on the curved part of the piano case.
5. Notice that one end of the PianoMic™ has a multi-connector shielded cable
coming out of the tube below the support arm (Figure 8). It doesn’t matter which
side of the piano the cable exits. The main objective is to place the PianoMic™ in
the piano so that the microphone heads can be easily placed 2 to 3 inches in front of
the dampers. The cable is long enough to easily reach the opposite side of the piano
should you decide to locate the electronics box on the opposite side of the piano from
where the cable comes out of the PianoMic™. You will need to position the cable so
it does not lie on top of the support arm. The combined thickness of the support arm
with the cable on top if it would exceed the size of the opening between the piano
case and the lid. Therefore when the lid is closed it would pinch and deform the
cable. To avoid this, place the cable to one side of the support arm. You may also
position the cable so it comes out the open area of the piano as illustrated in Figure 8.
