SAFETY PRECAUTIONS
Be sure to read the instructions in this section carefully
before use.
Make sure to observe the instructions in this manual as
the conventions of safety symbols and messages
regarded as very important precautions are included.

SafetySymbol and Message Conventions
Safety symbols and messages described below are used
in this manual to prevent bodily injury and property
damage which could result from mishandling. Before
operating your product, read this manual first so you are
thoroughly aware of the potential safety hazards as well as
understand the safety symbols and messages.
Be sure to use this matching transformer only for the
specified speakers. If any other speaker is used, the
transformer could detach and fall, resulting in personal
injuries. Also, the transformer could generate heat,
causing a fire.
CAUTION
Indicates a potentially hazardous
situation which, if mishandled, could result in death or
serious personal injury.
Indicates a potentially hazardous
situation which, if mishandled, could result in moderate
or minor personal injury, and/or property damage.
When installing the matching transformer, consult the
shop from where it was purchased because installation
requires specialized skills and professional experience. If
the transformer should fall, it could result in personal
injuries.
Avoid using an 83 tap when the speaker line of high
impedance is a 100 V line. Otherwise, heat builds up in
the matching transformer, possibly causing a fire.
The MT-S0601 matching transformer is designed to be installed in the speaker and used to convertthe low-impedance
speaker into the high-impedance version.
INSTALLING THE MATCHING TRANSFORMER
1. Remove four screws holding the blank panel to the
speaker and remove the panel.

as to permit the connection of the matching transformer.
Take the lead wire out of the speaker to disconnect the
connection.
Connect two lead wires to the transformer.
5. Replace the blank panel/transformer assembly in the
