Controls and Connectors
1 Input jacks (CH1 and CH2)
These are balanced combo jacks that support both XLR and phone plugs (both CH1 and CH2), and RCApin plugs (CH2 only). 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
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.
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].
7 [SIGNAL] indicator
Indicates (lit in green) when an audio input signal exceeds the minimum threshold.
8 [PROTECTION] indicator
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
