5. Setup

Follow these steps to set up your Jindaaudio mixer:

1. Power Connection:

   Connect the provided power adapter to the mixer's power input and then to a suitable power outlet. Ensure the mixer's power switch is in the OFF position before connecting power.
2. Connecting Microphones:

   For condenser microphones, connect them to the XLR inputs. Activate the 48V phantom power switch only after connecting the microphones. For dynamic microphones, connect them to the XLR inputs; phantom power is not required and should remain off for these types of microphones.

3. Connecting Line-Level Devices:

   Connect instruments, media players, or other line-level audio sources to the 1/4" TRS or RCA line inputs on the respective channels.

4. Connecting Output Devices:

   Connect your main speakers or recording interface to the MAIN OUT (XLR) connectors. For monitoring, connect headphones to the headphone jack or monitor speakers to the MONITOR OUT.
5. USB Connection (for PC/Mac):

   Connect a USB cable from the mixer's USB port to your computer. The mixer will function as an audio interface, allowing you to play audio from your computer or record the mixer's main output.

6. Operating Instructions

6.1 Basic Operation

1. Power On: After all connections are made, switch the mixer's power button to the ON position.
2. Adjusting Input Levels:

   For each active channel, speak into the microphone or play your instrument. Adjust the GAIN knob until the PEAK LED flashes only occasionally. Then, use the channel's volume fader to set the desired level.

3. Equalization (EQ):

   Use the TREBLE, MID, and BASS knobs to shape the tone of each channel. Turn clockwise to boost frequencies and counter-clockwise to cut them.

4. Main Output Level:

   Adjust the MAIN fader to control the overall output volume. Monitor the LEVEL INDICATOR to ensure the signal does not consistently peak into the red.

6.2 Bluetooth Connectivity

The mixer features built-in Bluetooth for wireless audio streaming from compatible devices.
