8.2.2.  Use of the Metal Plates

Use the supplied metal plates to mount the Sub-Units in the following cases:

• When the partition onto which the Sub-Units are to be mounted is over 10 mm (0.39") in thickness.

• When the two Sub-Units are not to be magnetically attached to each other.  

• When the Sub-Units require a stronger mounting. 

Note

When using the metal plates, do not attach the rear 

panels of two Sub-Units to each other. If attached, 

howling will result even at low volumes. 

 

Step 1. 

Be sure to remove dust, oil and grime, etc. 

from the mounting surface. 

Note

Wipe clean. If dirt or grime is not sufficiently 

removed, the Sub-Unit’s magnetic strength 

could  be  severely  weakened,  potentially 

causing the Sub-Unit to fall. 

 

Step 2. 

Peel  off  the  backing  paper  on  the  back 

surface of the metal plate and affix the metal 

plate to the intended mounting position. 

Note

Securely attach the metal plate by pressing 

firmly  on  it.  Failure  to  firmly  press  on  the 

metal plate when attaching it to the partition 

could  result  in  a  weak  initial  attachment, 

leading to the metal plate peeling off when 

the  Sub-Unit  is  removed  or  the  mounted 

Sub-Unit falling.

 

Step 3. 

Align  the  metal  plate  with  the  Sub-Unit’s 

magnet  and  mount  the  Sub-Unit  to  the 

partition. 

Notes

• When  mounting  the  Sub-Units  to  the  partition  by 

magnetically sandwiching it between them, ensure 

that they are positioned at least 15 cm (5.91") away 

from the nearest edge of the mounting surface. If 

the distance to the edge is less than 15 cm (5.91"), 

howling could be produced.

• When  mounting  the  Sub-Units  to  a  partition 

without aligning their rear panels with each other, 

if the distance between the Sub-Units is too short, 

howling  could  result.  In  such  cases,  either  lower 

the volume or change the mounting locations of the 

Sub-Units.
