Step 3. Connect a lead wire to the desired impedance tap.
Step 4. Disconnect the lead wire connectors and connect them to the matching transformer.
4-1. Pull the connectors out of the speaker and disconnect the interlocked connectors.
4-2. Connect the removed connectors to the connectors from the transformer.
Never connect to an 83 Ω tap when using the speaker on
high impedance 100 V line. Otherwise, heat builds up in the
matching transformer, possibly causing a fire.
CAUTION
Note
Make wiring to the tap before installing the transformer
into the speaker. Note that the tap cannot be changed
from the outside once the transformer has been
installed.
