For the combo jacks, connect a mixer, microphone, or digital musical instrument such as a keyboard. For RCA-pin jacks, connect a device such as an MP3 player or a CD player. For devices with high level signals such as a mixer, connect to CH2, or connect to CH1 then set the [MIC/ LINE] switch (3) to [LINE]. Background music source C XLR 6 1 7 2 3 8 9 0 4 A Phone Subwoofer RCA-pin Mixer Subwoofer 2 [LEVEL] knobs Adjust the level of each input jack (1). 3 [MIC/LINE] switch Set this switch to [MIC] or [LINE] for the CH1 jack, depending on the level of the input signal. For lowlevel signals (such as microphones), set the switch to [MIC]. For high-level signals (such as mixer), set the switch to [LINE]. 4 Output switch Selects the output signal sent to the output jack (5). [CH1 THRU]: Delivers the direct output signal of CH1 only. Signal from CH2 will not be output. [CH1+2 MIX]: Outputs the mixed signals of CH1 and CH2. 5 Output jack This is a balanced XLR jack. This can be used to connect another DBR speaker. Outputs the signal selected by 4 output switch. 6 [LIMIT] indicator Indicates (lit in red) that the limiter is on when the output voltage of the amplifier has exceeded the maximum level, or when excessive integral power consumption is detected. If this indicator stays lit, lower the input level. Note Integral power consumption refers to the sum of power provided to the speaker driver per unit time. Floor monitor system This system is suitable for a performer’s monitoring system. For use as a vocal monitor, set the [D-CONTOUR] switch to [MONITOR]. If necessary, you can additionally connect up to four speakers in parallel. In this case we recommend that the signal is input to CH1 and the output switch is set to [CH1 THRU]. Mixer 7 [SIGNAL] indicator Indicates (lit in green) when an audio signal exceeding the threshold has been detected. 5 8 [PROTECTION] indicator B C D E Bottom Indicates (lit in red) when the protection circuit is active. The protection circuit will be activated and the speaker outputs will be muted in the situations listed below. • If amplifier overheating is detected • If overcurrent is detected • When turning the power on; the protection circuit will be activated for a few seconds to prevent noise. The indicator turns off when the power supply has started normally. If the protection circuit has engaged, waiting until the amplifier cools down or powering off and on again will return to normal operation.
