5.1 Power Connection (Active Mode)
If you require signal amplification or are using low-output devices, operate the mixer in active mode:
- Ensure the Active/Passive Mode Switch is set to 'IC' (Active).
- Connect the provided USB-C cable to the 'DC 5V' port on the mixer.
- Connect the other end of the USB-C cable to a 5V DC power source (e.g., USB wall adapter, computer USB port, power bank).
- Flip the Power ON/OFF switch to 'ON'. The Power Indicator LED will light up.
5.2 Passive Mode Operation
For pure audio signal transmission without amplification, the mixer can operate passively without external power:
- Ensure the Active/Passive Mode Switch is set to 'PASS' (Passive).
- No external power connection is required.
5.3 Helisisendi ühendus
Connect your audio sources to the 'IN-1' through 'IN-4' 3.5mm AUX input jacks.
- Use standard 3.5mm audio cables for each source.
- Each input can be independently controlled.
5.4 Heliväljundi ühendus
Connect your listening device to the 'OUT' 3.5mm AUX output jack.
- Connect headphones, powered speakers, or an amplifier using a 3.5mm audio cable.

6. Kasutusjuhised
6.1 Adjusting Input Volumes
Each input channel (IN-1 to IN-4) has a dedicated rotary knob. Turn the knob clockwise to increase the volume of that specific input, and counter-clockwise to decrease it. Adjust each source to your desired level.
6.2 Adjusting Master Output Volume
The 'VOL' knob controls the overall output volume of the mixed audio. Adjust this knob to set the final listening level for your headphones or speakers.
6.3 Active vs. Passive Mode Usage
- Active Mode (IC): Pakub amplification for your audio signals. This is recommended when using low-output devices or when you need a stronger output signal. Requires 5V DC power via the USB-C port.
- Passive Mode (PASS): Mixes audio signals without amplification. This mode is suitable for line-level sources that already have sufficient volume and when you prefer a pure, uncolored audio signal without external power.
