8. REPAINTING THE FRONT GRILLE
Follow the procedures below to change the color of the grille.
1. Wipe dirt off the front grille with a soft cloth moistened with a detergent before painting. Do not use volatile
liquids such as thinner.
2. Uniformly spray a thin coating of paint over the grille changing the spraying positions gradually.
Notes
• Do not use a roller or brush to paint because the meshes of the grille could be clogged with paint.
• Use paint that is appropriate for the composition of the front grille (grille and frame).
[H-2] Grille: Rolled steel plate
Frame: Fire-resistant ABS resin
[H-2WP] Grille: Stainless steel
Frame: AES resin
• Follow the instructions on the paint when painting.
3. After the paint dries, repeat Step 2 once or twice to repaint.
Note: Be sure to repeat Step 2 at least twice.
9. 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.
10. EQUALIZATION
• The H-2 and H-2WP are designed to provide good quality sound without additional equalization. However,
by equalizing them 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.
