CONTROL panel
1. LINE/MIC INPUT
These balanced inputs accept a standard XLR (female) connector
and a 1/4 “ TRS phone jack connector. A range of signals from
microphones, audio mixing consoles, and electronic musical
instruments may be connected here. The sensitivity of this input is
controlled by the LINE/MIC SWITCH. This input does not provide
phantom power.
2. LINE/MIC SWITCH
The selector must be in the "MIC" position for MIC inputs. The MIC
setting should only be used if a microphone is connected directly
to the in MIC/LINE input.
CAUTION:
Using the MIC setting for other purposes may introduce
distortion. For other sources the selector must be in the "line"
position, this should be used for most other audio inputs.
3. INPUT LEVEL KNOB
Sets the sensitivity of input A and B channel which controls the
signal level sent to the amplifier and the mix out .
4. MP3 LEVEL KNOB
Turn this knob to adjust the input volume of USB flash or
Bluetooth input.
5. MASTER KNOB
To adjusts master volume of all inputs (the Mix out will not be
controlled by this knob.)
Use these knobs to adjusts the 3 different frequencies of the
speaker.
TREBLE:
Increases or decrease the high frequency for MIC / LINE /
MP3 sources at a range between -10dB to +10dB.
MID:
Increases or decrease the middle frequency for MIC / LINE /
MP3 sources at a range between -10dB to +10dB.
BASS:
Increases or decrease the Low frequency for MIC / LINE /
MP3 sources at a range between -10dB to +10dB.
7. MIX OUT
Output XLR is a mix of channels A/B and MP3 player. Produces a
line-level output signal that is Post Gain. Any adjustments made
to the gain of these A/B channel and MP3 affects this output
signal. It works as signal output to link the other active speaker.
8. AC INPUT
Standard IEC AC input connector. 230V/5A AC fuse.
9. POWER SWITCH
Will illuminate when power is applied to the unit and the ON/OFF
switch is in the ON position.
10. VOLTAGE SELECTOR
Allows user selection of different local voltage ratings 115V/60Hz
- 230V/50Hz.
When power is applied to the unit and the ON/OFF switch is in the
ON position this LED will be illuminated.
This LIMIT LED illuminates when the output power is in overload.
The red clip LED indicates that limiting has taken place to protect
and avoid damage to the amplifier or loud-speaker. Continuously
over driving the system will cause distortion and may lead to
premature failure to the speaker system. If the red limit led is on
when both LEVEL controls are at minimum, your loudspeaker
requires service by qualified professional.
