SAFETY PRECAUTIONS

GENERAL DESCRIPTION

INSTALLING THE MATCHING TRANSFORMER

• Be sure to read the instructions in this section carefully before use.

• Make sure to observe the instructions in this manual as th e conven t i o ns of saf e t y symb o l s and m e ssages regarded as very important precautions are included.

• We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are used in thi s man ual t o pre vent bodi ly in jury and prope rty 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 transforme r c ould generate he at, causing a fire.

• 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.

1. Remove four screws holding the blank panel to the speaker and remove the panel.

2. Mount the matching transformer to the back side of the blank panel. (Use screws and nuts attached to the blank panel.)

WARNING

CAUTION

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. Connect a lead wire to the desired impedance tap.

4. Disconnect the lead wire connectors to change wiring so 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 speaker.

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.

Note: The design and specifications are subject to change without notice for improvement.

Avoid using an 83 Ω tap when the speaker line of high impedance is a 100 V line.

[Note]

Select the tap before installing the transformer in the speaker. (Note that the tap cannot be changed from the outside once the transformer has been installed.)
