2. HOW TO USE

2.1. Handling Precautions

When  installing  the  speaker,  be  sure  the  drain  hole  is  positioned  facing  the  ground.

Without the drain hole positioned correctly, rain could flood the speaker, causing it to fail.

Be  sure  to  note  the  following  polarities  when  multiple  speakers  are  used  in  the  same  location.  Incorrect  connections

could result in no bass output or decreased volume.

Black speaker cable: Positive (+), White speaker cable: Negative (–) or COM

Connect the cables to other cables of the same colors in parallel connections, and to cables of different colors in series
connections.

To  avoid  amplifier  failure,  do  not  simultaneously  connect  both  low-  and  high-impedance  speakers  to  the  amplifier.

Ensure that only one type is connected.
Notes: (1) "Low-impedance" refers to speakers having no built-in matching transformer.

(2) "High-impedance" refers to speakers having a built-in matching transformer.

Ensure  only  the  specified  line  voltage  (amplifier  output  voltage)  is  used  for  the  high-impedance  speakers.  The  line

voltage  is  indicated  on  the  name  plate  as  [70/100  V  LINE].  If  an  unspecified  line  voltage  is connected, fire or 
equipment failure could result.

2.2. Connections

The total rated input of all connected speakers must be equal to or smaller than the amplifier output. If the total speaker
input rating is greater than the amplifier output, the amplifier could fail. Connect all speakers in parallel.

2.3. Impedance Selection

Select the desired impedance by inserting a screwdriver into the impedance selector switch slot and turning the switch.
The OFF position disconnects the speaker from the amplifier and no sound is output.
Notes: (1) Speakers are factory-preset for the highest rated input of two line

voltages (i.e. 100 V line in the case of the 70/100 V line version).

(2) The speaker's rated input and impedance are indicated on the

name plate.

Speakers  are  designed  to  select  either  of  the  two  line  voltages  (rated
amplifier  output  voltage).  Check  to  confirm  the  line  voltage  to  use,  and
select the line voltage impedance specified on the name plate.

Do not use the impedance selector switch position marked as [X], because
this position could result in amplifier or speaker failure, or fire.
