System Setup Connections and Controls

1. Indicator light: Displays the input signal status in color.

   • Green: Signal Power
   • Yellow: Signal
   • Red: Signal Limit

2. Bluetooth & TWS: Used Bluetooth Button to set up pairing with Bluetooth-capable devices, such as mobile phones, tablets
   and laptops. Press the TWS button on the same time on both 2 speakers, and wait them paired (one TWS LED blink slow,
   the other one doesn’t blink), then connect Bluetooth-capable devices to systems to achieve stereo sound play.

3. Line input channel 1: RCA and XLR/6.3 mm jacks for connecting audio units with line level output (e.g. mixer, CD player,
   music instrument).

4. Feed-through output LINK: Balanced XLR jack to pass either the input signal of channel 2 or the master signal
   to another device, e.g. a further active speaker system.

5. Output selector switch CH 1/MIXED: Determines the signal at the link output.

   • switch disengaged= Output of the input signal of channel 1.
   • switch engaged = Output of the master signal.

6. Mic/line input channel 2: Combo input {XLR/6.3 mm jack) for connecting microphones or audio units with line level output
   {e.g. mixer, CD player, music instrument).

7. Fan : Do not cover to avoid overheating.

8. DSP PRESET switch: To select various equalizer presets: FLAT= neutral frequency response, MUSIC= low and high frequency
   boost, LOW CUT= low and high frequency cut, mid boost.

9. Level control CH 1 VOL: Adjust the level of channel 1.

10. Input selector switch Bluetooth/LINE: Switches the signal input of channel 1 between bluetooth and line input.

    • switch disengaged= Bluetooth input.
    • switch engaged= Line 1 input.

11. D Level control CH 2 VOL: Adjust the level of channel 2.

12. Input selector switch MIC 2 / LINE 2: Switches the signal input of channel 2 between line and microphone input.

    • switch disengaged= microphone input.
    • switch engaged= line input.

13. Power switch: Turns power to the speaker system on and off.

14. Power input with fuse holder: Used to plug in the supplied power cord. Only replace the fuse when the device is disconnected
