Follow these steps to set up your LiNKFOR 4 Channel Stereo Audio Mixer:

1. ການເຊື່ອມຕໍ່ພະລັງງານ: Connect the provided USB Type-C power cable to the DC 5V input port on the mixer. Connect the other end of the USB cable to the power adapter, and then plug the adapter into a standard electrical outlet. While the mixer can function passively for basic mixing, connecting power ensures optimal performance and signal integrity, especially with lower impedance sources.
2. ການເຊື່ອມຕໍ່ຂາເຂົ້າ: Identify your audio sources (e.g., laptop, phone, keyboard, electric guitar, CD player). Use appropriate 6.35mm (1/4 inch) TRS or TS cables to connect each source to the INPUT 1, INPUT 2, INPUT 3, and INPUT 4 jacks on the mixer. Ensure secure connections for each channel you intend to use.
3. ການເຊື່ອມຕໍ່ຂາອອກ: Connect your output device (e.g., headphones, powered speakers, amplifier, sound card) to the OUTPUT jack on the mixer using a 6.35mm (1/4 inch) TRS cable.
4. ການຕັ້ງຄ່າລະດັບສຽງເບື້ອງຕົ້ນ: Before powering on or playing audio, set all LEVEL 1-4 knobs and the main OUTPUT knob to their minimum positions (fully counter-clockwise) to prevent sudden loud sounds.
5. ເປີດ: Press the POWER switch on the mixer. The green LED indicator will illuminate, confirming the unit is powered on.

6. ຄໍາແນະນໍາການດໍາເນີນງານ

Once the mixer is set up, follow these instructions for operation:

1. ການປັບລະດັບການປ້ອນຂໍ້ມູນ: Gradually increase the LEVEL knob for each active input channel (LEVEL 1-4) until the desired volume is achieved for that specific source.
2. Master Output Volume: Once individual input levels are set, slowly turn the main OUTPUT knob clockwise to increase the overall volume of the mixed audio. Adjust this knob to control the final volume sent to your speakers or headphones.
3. Mono/Stereo Switching: Use the MONO/STEREO switch to select your preferred output mode. In stereo mode, the left and right channels of each input are preserved. In mono mode, all input signals are summed to a single mono signal, which is then sent to both left and right output channels.
4. ການຕິດຕາມສຽງ: Listen to the mixed audio through your connected headphones or speakers. Make fine adjustments to individual input levels and the master output level as needed to achieve a balanced and clear sound.
