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.
