Step 2. Wiring and impedance settings

 

Step 2-1.Unplug the detachable input connector from

Detachable input connector

the speaker socket, and loosen the screws

 

of the terminal with a screwdriver.

 

Step 2-2.Insert the stripped cable ends into the input connector, and retighten the terminal screws.

[Bridge connection]

From power amplifier

To next speaker

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.
