3.4 Recording Mode Selection (REC)

The REC button allows you to select the audio source for computer recording:

• Button Up (MIC): Records only the microphone/instrument inputs (Channels 1 and 2).
• Button Down (MIC+PC): Records a mixed signal of the microphone/instrument inputs and the audio playback from your connected computer.

3.5 Stereo/Mono Channel Switching (ST PAN)

The ST PAN buttons (1L and 2R) control the stereo panning or mono summing of the input channels:

• Buttons Up: Channels 1 and 2 are treated as separate mono inputs, panned left and right respectively.
• Buttons Down: Channels 1 and 2 are summed to a mono signal. This is useful when using a single microphone and wanting the sound to be present in both left and right channels of the output.

3.6 Main Output and Headphone Volume

Laraskan UTAMA knob to control the overall output volume to your speakers or recording device. Use the TELEFON knob to adjust the volume for your connected headphones.
