11. With the PianoMic™ placed in-
side the piano and the microphones
properly positioned you are ready to
connect the PianoMic™ cable to the
electronics box via a 5-pin XLR con-
nector. The back of the electronics
box has two XLR-3 connectors that
will connect the microphone outputs
to the preamp inputs of your mixer
(See Figure 13).
12. Notice in Figure 14 that
the top of each microphone
head has a number. These
numbers correspond to the
numbers on the rear of the
electronics box. Depending
upon how the PianoMic™ is
placed in the piano the high
strings will be indicated by
either the number 1 or num-
ber 2. Once the PianoMic™
has been placed, identify the
microphone numbers on the
mic heads for both the high
and low strings and remem-
ber that they correspond to
the numbers on the rear of the
electronics box. This will allow you to correctly identify the microphone sig-
nals for high and low strings that are connected to the preamps of your mixer.
Remember that the PianoMic™ requires 48-volt phantom power.
13. There are two ways to mount the electronics box: (1) in a leather pouch
strapped to the leg of the piano, or (2) attached to a short microphone stand.
The PianoMic™ System comes equipped to install the electronics box in
either of these two ways.

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
1. With the PianoMic™ assembled,
loosen the two clutches on either side
of the two microphone goosenecks
(See Figure 4). 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 4.
However, do not loosen the clutches
all the way; just enough so the bar can
be extended and still have a little fric-
tion. This will make it easier to adjust
the length of the bar from both ends
once it is placed inside the piano.
2. Extend both sides of the bar so
that it is wider than the piano.
3. 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 polyolefin coating to avoid scratching
the piano. The support brackets are
thin enough to allow the piano lid
to be completely closed with the Pi-
anoMic™ System inside the piano.
The PianoMic comes with felt pads
installed on the top of each support
arm. If you desire a more snug fit
with the lid closed or if vibration
becomes an issue, install one of the
enclosed spare felt pads on the bot-
tom side of the support brackets as
shown in Figure 5.
