7. MATCHING TRANSFORMER INSTALLATION
An optional MT-S0601 matching transformer can be installed in the HB-1 speaker.
Step 1. Remove the 13 enclosure cover fixing screws to detach the cover.
Step 2. Remove the two screws located inside an enclosure. Using the removed two screws, mount the MT-
S0601 transformer so that its connection tab is facing the front of the enclosure.
Step 3. Detach the woofer's lead wire junction connector, and connect it to the MT-S0601's connector.
Step 4. Connect the speaker input cable to the desired impedance tap.
Step 5. Replace the enclosure cover.
Step 6. Choose an appropriate impedance indication
label from those supplied with the MT-S0601,
and affix it over the HB-1's nameplate to indicate
the selected impedance.
