The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. The above warning is located on the rear of the unit. install in accordance with the manufacturer’s instructions. [. . . ] It features a BOOST mode that enhances and provides punch to the sound, and an XTENDED LF mode that extends the bottom of the low frequency range. You can select either mode in accordance with various applications and musical genres. Included Accessories • AC power cord • Owner’s manual (this book) Optional accessories U brackets for mounting the DXR series on the wall or ceiling are available as follows: • UB-DXR15 (for DXR15) • UB-DXR12 (for DXR12) • UB-DXR10 (for DXR10) • UB-DXR8 (for DXR8) 6 DXR15/DXR12/DXR10/DXR8/DXS15/DXS12 Owner’s Manual Controls and Functions Controls and Functions Rear panel 3 4 5 6 7 9 2 1 3 ) 1 8 3 4 5 6 7 8 1 ! $ % 3 2 1 1 # @ DXR15 , DXR12 , DXR10 , DXR8 DXS15 , DXS12 NOTE ^ 1 INPUT jacks These are balanced XLR input jack(s) (INPUT 1) , unbalanced phones (INPUT 2) and RCA pin input jacks (INPUT 3). You can connect a mixing console or microphone to INPUT 1, a keyboard or electric-acoustic guitar to INPUT 2, and a portable audio player or CD player to INPUT 3. Signals from INPUT 1-3 are mixed inside the DXR unit. The DXS series input features only balanced XLR input jacks (L, R). L and R signals are mixed inside the DXS unit. € If the output voltage of the amplifier has exceeded the maximum value, or if excessive integral power consumption is detected, the LIMIT indicator will light when the amount of attenuation is 3dB or higher. € The integral power consumption refers to the sum of power consumption provided to the speaker driver per unit time. Input signals will be passed through unaffected, since these are parallel connected to the INPUT jacks. 6 PROTECTION indicator Lights when the protection system is active. The protection system will operate and the speaker output will be muted in the following situations. € If amplifier overheating is detected: • If DC output is detected: • If overcurrent is detected: • When turning the power on: The protection system will be activated to prevent noise and the indicator will light for about two seconds. The indicator turns off when the power supply has started normally. € When turning the power off: Or if the power turns off due to an unexpected error, the protection system will be activated to prevent noise, and then the power will be shut down. NOTE 3 LEVEL control Adjusts the level of each INPUT signal. If you connect a device that features a nominal output level of +4dBu (such as a mixing console), set the MIC/LINE switch (9) on the DXR series to LINE, and adjust the LEVEL control using its 12 o’clock position as a reference. 4 LIMIT indicator Lights when the output limiter is active. The output limiter will operate in order to protect the speaker and amp, attenuating the output signal to the amplifier. If this indicator stays lit, lower the level of the input signal. If the protection system has engaged after the problem was detected, waiting until the amplifier cools down or powering off and on again will return to normal operation. [. . . ] A microphone is directed toward the Keep the speaker away from the area where the speaker. Sound howls (feedback) Lower the volume of the input device and locate the microphone more closely to the sound source. Set the HPF switch on 120Hz or 100Hz if you get feedback in low frequency bands. € (DXR series) Set the HPF and D-CONTOUR switches of each speaker to the same positions. [. . . ]
