Installation of the acoustic interface (driver unit)
[1] Double-sided tape
[2] Chassis
[3] Set screws
[4] Cable hole
[5] Ceiling sash, etc.
1. The driver unit is connected to the top of the upper acoustic tube.
Use the screws provided and double-sided tape to secure the
chassis to the position where the glass meets the ceiling.
2. Align the position with the guideline, and make a pilot hole in the
ceiling. When deciding the position, it is necessary to take into
account the extra thickness caused by the double-sided tape.
3.
When the position is determined, attach double-sided tape to the
glass (first attach double-sided tape to the bottom outer surface of
the chassis), and then secure to the ceiling with the screws provided.
Make the cable hole in the ceiling for the speaker cable and
microphone cable at the same time as making the screw holes.

Installation of the acoustic interface (lower acoustic tube)
Generally, it is likely that only one acoustic tube (1 m) will be used
for the lower acoustic tube.When using 2 or 3 tubes, refer to the items
in "4-9 Installation of the acoustic interface (upper acoustic tube)"
before installation.

[2] Discarded side (blue label side)

[4] Main unit
[5] Base
[6] Tube connector
[7] Red label
[8] Double-sided tape
[9] Fixing base of the lower acoustic tube
[10] Tube fixer
[11] Counter sash,etc.

[13] Connection groove
[14] Connection ridge
• Temporarily insert the red label side of the acoustic tube into the
connector on the bottom of the acoustic I/O tube, and align with the
installation surface. Keeping the acoustic I/O tube at the height that
was decided earlier, decide where the acoustic tube should be cut on
the bottom. The ideal cutting position would be at a length where
the bottom of the acoustic tube makes contact with the bottom of the
tube fixer when the tube is inserted into the fixer.
• Remove the tube connector that is installed on to the acoustic tube.
Move the packing installed on the tube connector to the bottom of
the acoustic I/O tube (microphone cord side).
•
When using only one acoustic tube on the lower side (1 m or less), the
removed tube connector is not used. When using 2 or more tubes, the
tube connector is used together with the packing in the connection.
•
Cut the acoustic tube at the appropriate length. When cutting the lower
acoustic tube, make sure that the side that is discarded is the blue label
side. Do not cut the red label side because it is the tube connection side.
• Cut while the acoustic tube main unit and fixing base are correctly
assembled together. This is easier if tape is used to secure both sides
so they are not misaligned.
• Cut carefully so that the cut surface is perpendicular to the long side
of the tube.
• After cutting,use a file or sandpaper to smooth the cut surface of the
acoustic tube main unit and fixing base so they can both be inserted
into the tube fixer.
1.
There are screws for setting the fixing base and acoustic tube main
unit at 5 cm, 35 cm, 65 cm and 95 cm from the blue label. Make
sure the cutting position is not the same as these fixing positions.
2. When cutting one acoustic tube and using it above and below
the acoustic I/O tube, use the blue label side of the acoustic
tube as the lower acoustic tube. Use the red label side of the
acoustic tube as the upper acoustic tube. The tube connector is
not used, but packing is used at the connection of the upper
acoustic tube and acoustic I/O tube.
2. Attachment
•
Pull out the acoustic tube main unit and fixing base,and attach
double-sided tape to the outer surface (flat surface)of the fixing base.
• After attaching the double-sided tape to the fixing base, position the
tube so that the red label is on the upper side,and insert the bottom
into the tube fixer.Align with the guideline while the tube makes
contact with the bottom of the tube fixer, and attach to the glass.
3. The double-sided tape can be seen from the operator side, so
when attaching make sure it does not protrude from the edges
and is not bent.
4. The acoustic tube main unit can be pulled out by sliding it up
10mm from the fixing base.
3.Check
•
After attachment,insert by aligning the connection ridge of the
acoustic tube main unit (with the red label on the upper side)and the
connection groove of the fixing base. Try to secure while pushing
downwards (the slide distance is approximately 10mm). Check that
the tube can be inserted to the bottom of the tube fixer and that it can
be fully secured.After checking,remove the acoustic tube main unit.
Do not apply excessive force,as the adhesive power of the double-
sided tape will not yet have reached its full strength.
