Safety Symbol 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 rst
and understand the safety symbols and messages
so you are thoroughly aware of the potential safety
hazards.
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
WARNING
•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.
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
CAUTION
• 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 Ω 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.
2. GENERAL DESCRIPTION
The MT-S0601 matching transformer is designed to be
installed in the speaker and used to convert the low-
impedance speaker into the high-impedance version.
3. INSTALLING THE MATCHING
TRANSFORMER

Step 3. Connect a lead wire to the desired impedance tap.

Step 4. Disconnect the lead wire connectors to change
wiring so as to permit the connection of the
matching transformer.
4-1. Take the lead wire out of the speaker to disconnect
the connection.
4-2. Connect two lead wires to the transformer.
Step 5. Replace the blank panel/transformer assembly in
the speaker.
Step 6. Separate the corresponding impedance indication
label from the impedance seal supplied with
the transformer and attach it to the impedance
indication area in the speaker name plate.

tap cannot be changed from the outside
once the transformer has been installed.)
Avoid using an 83 Ω tap when the
speaker line of high impedance is
a 100 V line.
