5. INPUT TERMINAL SECTION

•As the Speakon connector is internally connected in parallel to the screw terminal as shown below, you can use either of the two.

•The usable connector (on the cable end) that matches the NEUTRIK NL4MP Speakon is NEUTRIK NL4FX Speakon.

•Input terminal connection diagram is as shown below.

6. IMPEDANCE CHANGE

[Rear]

To change the impedance, use a standard screwdriver to rotate the rotary switch on the speaker's rear panel to select the desired input power.

This switch is factory-preset to 670 Ω.

Note

When using a high-impedance amplifier, never select 8 Ω, as this will damage the speaker and the amplifier.

Be sure to turn the rotary switch to 8 Ω when using a low- impedance amplifier.

7. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUIT

The speaker system has a built-in input overload protection circuitry. If an excessive input signal is applied to the speaker, the protection circuitry is activated and cuts off the signal input to the tweeters. A sudden drop of the sound volume level during speaker operation indicates that the protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset after approximately 10 seconds. After the circuitry is reset, set the volume at a lower level than before.

Note

This input overload protection circuitry does not completely protect the speaker component. Depending on the nature of the excessive input signal applied to the speaker, there may be damage to the speaker components before protection circuitry can operate. Also, if the excessive input signal is applied to the speaker for extended periods of time, the protection circuitry may be damaged and will not recover. Take special care that the excessive input signal is not applied to the speaker during use.
