Control Panel
Let's take a look at the product's rear panel.
Firstly, we have the power input section,which includes a power switch and a power input socket;the LED display section, which consists of the following indicators: the first is the power supply indicator, the second is the signal indicator,the third is the limiter indicator, the fourth is the system anomaly indicator.Finally, we have a button switch to enable or disabling the LED light on the speaker front panel. Moving on, let's understand its signal input section.
The signal input section features two sets of line-level inputs: Channel A and Channel B. Below them are the corresponding input gain adjustment knobs for A and B. Channel A has a switch that enables you to choose between line and microphone input with 48V phantom power.
On the right, we see a Bluetooth logo. By pressing and holding the button below it,the LED indicator will flash continuously. At this point, on the mobile device, we can find the Bluetooth input signal of this speaker and connect to it. Below is the input gain adjustment knob. That sums up all signal input section. Regarding the output section,we can see this interface which is the MIX OUT.When we input signals from A, B, or Bluetooth, we can achieve mixed signal output through this output. This knob switch controls the overall output gain of the entire speaker set. This smaller knob is for the low-frequency gain. Then, we can see a USB interface here, which is used for the import of system presets.
Above it, there is a toggle switch that is mainly used for the quick setup of the subwoofer with different full-range speakers.This is the mainlayout of the signal routing section on the rear panel. Regarding the connection between the subwoofer and the full-range line array, what method will we use? We will use Speakon wiring for the connection. After inserting the cable into this connector on the subwoofer,we then connect the full-range line array. This way we will have the complete system connected. Then, we just need to connect the power supply and the audio signal, and the system can operate normally.
Bluetooth Connection
Turn on the power switch. Then, press and hold the Bluetooth button until the indicator light flashes continuously.
Now, press the Bluetooth button on the other desired speaker until it flashes continuously as well.Once the pairing is complete, the indicator lights will keep solid, so the system has successfully connected.At this point, activate Bluetooth on your mobile device, and you will see the available device "AC-L." Tap on it to initiate pairing.At this moment, your phone's Bluetooth should display "Connected for media audio." Alright, now we will use your phone to play music to check if the Bluetooth connection is functioning properly.Then, we will also verify if the other speaker is connected to Bluetooth correctly. For the transportation of the L MK2 series line array, there are two primary methods available. The first method involves the use of flight-cases. The second method uses a wheeled platform dolly. Whole system is designed for plug-and-play functionality, with the capability to quickly recall preset modes.
