7.Attach the grille to the speaker with its two mounting screws.

8.Reattach the mounting bracket to the speaker with the angle adjustment screw.

8.PROTECTION CIRCUITRY INFORMATION

• The speaker has built-in overload protection circuitry.

If there is an extremely high level input signal to the speaker, the overload protection circuitry is activated and cuts off the signal input to the speaker component.

A sudden drop of the sound volume level during speaker operation indicates that the overload protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset after approximately 3-30 seconds. After the circuitry is reset, set the volume at a lower level than before.

Important Note

This overload protection circuitry does not completely protect the speaker component. Depending on the nature of the excessive signal applied to the loudspeaker, there may be damage to the loudspeaker components before the protection circuitry can operate. Also, depending on the duration of the excessive input signal, the protection circuitry may be damaged and will not recover. Take special care that the excessive

input is not applied to the speaker during use.

9. EQUALIZATION

The H-1 is designed to provide good quality sound without additional equalization. However, by equalizing it as shown below, sounds can be made more powerful and intelligible.

Using a digital signal processor such as DP-0202 or DP-0204, make the following equalization setting.
