Note
When not bridging the connection, tighten the screws of unused terminals to prevent resonance
noise.
Step 2-3. Attach two sockets to the impedance selection connector to select the desired impedance.
The impedance is preset to 330 Ω (30 W for 100 V line and 15 W for 70 V line).

Note
The H-3 and H-3WP speakers are designed to be used for both 70 V and 100 V line applications.
When using the 100 V line, do not select the "170 Ω" impedance, since the speaker itself or power
amplifier may be damaged.
