Figure 4: Detailed diagram of the G-MARK STUDIO 2 mixer controls.

3.1 Input Level Controls

Juster NIVEAU 1 og NIVEAU 2 knobs to set the input gain for each channel. Monitor the 'SIG' (signal) and 'PEAK' (overload) indicator lights. The 'SIG' light should illuminate green during normal operation, and the 'PEAK' light (red) should only flash occasionally. If 'PEAK' stays red, reduce the input level to prevent distortion.

3.2 Fantomstrøm (+48V)

Tryk på +48V PHANTOM(CH1-2) button to activate phantom power for condenser microphones connected to INPUT 1 or INPUT 2. Ensure this is only used with microphones that require phantom power.

3.3 Hi-Z Input

Tryk på HI-Z button when connecting high-impedance instruments like electric guitars or basses directly to the mixer for proper signal matching.

3.4 Recording Mode Selection (REC)

De 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)

De 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 Hovedudgang og hovedtelefonlydstyrke

Juster HOVED 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.
