Extending the loudspeaker array
1. Align the connector on
the bottom of the LED
extension with the socket on
the power stand, then push
the LED extension into the
power stand. (Be sure to
fully insert the extension into
the power stand socket to
assure stability and a good
connection)
Amplifier controls
The amplifier has a combination of controls and
connectors to ensure the most versatile loudspeaker
system.
ZL-10AT amplifier 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. The LINE setting
should be used for most other audio inputs.
3. INPUT LEVEL KNOB
Sets the input sensitivity 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. MIX OUT
Output XLR is a mix of MIC/line channel, AUX IN channel and MP3 player. Produces a line- level
output signal that is Post Gain. Any adjustments made to the gain of these knobs will affect this
output signal. It works as signal output to link the other active speaker.
6. AUX IN
Connect your digital media player, smart phone, or other audio device with the 3.5mm connec-
tor(included) to this stereo auxiliary input. Input level will be controlled by AUX LEVEL.
7. AUX LEVEL
Sets the sensitivity of AUX IN input which controls the signal level sent to the amplifier and the
mix out.
8. BASS
Increases or decrease the Low frequency for MIC/LINE/AUX/MP3 sources at a range between
-10dB to +10dB.
9. MID
Increases or decreases the middle frequency for MIC/LINE/AUX/MP3 sources at a range
between -10dB to +10dB.
10. TREBLE
Increases or decreases the high frequency for MIC/LINE/AUX/MP3 sources at a range between
-10dB to +10dB.
11. MASTER
Adjusts the master volume of all inputs. (The mix out will not be controlled by this knob.)
12. POWER LED (BLUE)
Will illuminate when power is applied to the unit and the ON/OFF switch is in the ON position.
13. LIMIT INDICATOR (RED)
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 limit LED indicator flashes, turn down the MASTER knob.
14. MEDIA PLAYER.
MP3 or TWS control here.
15. AC INPUT
Standard IEC AC line input connector. 230V/5A AC fuse.
16. POWER SWITCH
Enables the AC power to the unit (on/off)
17. LED LIGHTS SWITCH
Enables front LED lights (on/off)
18. VOLTAGE SELECTOR
Allows user selection of different local voltage ratings 115V/60Hz - 230V/50Hz.
