However, please check the following three points to prevent the problem from recurring. • If the level setting is excessive, lower it to the nominal level.You can refer to the peak level indicators of the main section when doing so. • If the device is not ventilated sufficiently, refer to the cautions given at the beginning of this manual and take appropriate measures to insure adequate ventilation. • If the load impedance (including a short) is too low, refer to the chapter on connections (page 15) and change the connections so that the impedance is correct. Other Connections between devices have come loose. Inspect the connections, and correct any faulty connections. Other The device may have malfunctioned. Please contact your dealer. Powered Mixer Q&A Q: The built-in effect is not effective. A: The ON switch in the DIGITAL EFFECT section may not be turned on. Or, you have adjusted the EFFECT control in the Channel section or the EFFECT RTN control in the MAIN section.
