A. Mounting the treble mics
1. Remove grill cover o the treble side.
2. Mark the position of the two medium G keys on the
inside of the grill, as well as an assumed centre line
between the black and white keys.
3. Along this centre line, attach the long soft Velcro strip
and stick the underside of the treble mics to the G key
marks.
4. As shown in picture, lead the cables out of the grill
towards the high octave keys and secure them with
the 2 small hard Velcro pieces on the long strip.
5. Now, choose a suitable position for the preamp.
a. Do not transport your instrument with mounted
preamp. If it comes loose it could damage your
instrument.
b. The output amp cable should not be bent when
the instrument is put on the oor.
6. Mount the preamp using the pre-attached Velcro.
7. Insert the plugs of the two treble mics into the
‘Melody Mics In’ inputs.
B. Mounting the bass mic
1. Remove the bass side grill cover.
2. Select a suitable position for the bass mic at the bot-
tom part of the inside of the cover.
3. Attach the microphone with the Velcro. For instru-
ments without grill cover, the bass microphone needs
to be mounted directly inside on the tuning block.
For this purpose, you will need to drill a small hole
through the tuning block to thread the small mic
cable through. Unsolder the jack rst, and re-solder
it after installation. The hole should be lled with
silicone or putty. We recommend having this done by
a qualied instrument technician.
4. Route the cable towards the corner between the
housing and cover (usually it is necessary to le the
cover side). Replace the cover, where you please take
care not to damage the thin cable. Then attach the
hand strap again.
The two connected treble microphones are installed on the inside of the treble grill. The single bass mic is mounted on
the inside of the bass side.
Prior to rst using the microphone system according to the following instructions, please insert a fresh 9V battery into
the preamp. Therefore slide the labelled lid with slight pressure upwards to overcome the clamping assembly. Insert the
battery into the designated compartment.
