If the supplied tapping screws are not appropriate for the
construction of wall, separately prepare the appropriate screws.
Install the speaker receptacle referring to its "UP" mark.
Position the receptacle at the specified distance away from any
object above and below it for vertical speaker mounting. Keep
the same distance to the right and left of the receptacle
(positioned sideways) for horizontal speaker mounting.

4. INSTALLATION
Step 1.
Attach the speaker receptacle to a wall.
[Notes on horizontal speaker mounting]
• Even if the speaker receptacle is mounted
horizontally, the speaker may be tilted due to its
weight unbalance when attached to the receptacle.
• When changing the logo direction, peel off the logo
carefully as it is affixed using double-faced tape.
Then, re-affix it in the right orientation.
[Exposed wiring]
Notch the top of the speaker receptacle using long-
nose pliers, then make connections.
Speaker cable
Split the speaker cable into 2 branches just before it
enters the speaker receptacle so that it can be routed in
the cable-guide groove on the rear side of the speaker.

Step 2.
Change the input power (impedance) as needed.
The input power (impedance) is factory-preset to
1 k
Ω
for 10 W/100 V line or 5 W/70 V line.
When changing this setting, use a standard
screwdriver to turn the rotary switch on the
speaker's rear panel to the desired position.
Note
Be sure to follow the instructions below. Failure
to do so may cause damage to the speaker as
excessive input power is applied to it.
· Switch off the amplifier's power when changing
the input power.
· Never make 500
Ω
connection in a 100 V line
system, as excessive input power is applied to
the speaker, possibly resulting in damage.
Step 3.
Hold and slide the speaker to insert its speaker
plug into the speaker receptacle.
Note
In this case, force the speaker onto the speaker
receptacle holding the speaker outer frame.
