3. Návod k obsluze

3.1 Základní obsluha

• Zapnutí/vypnutí: The Quantum ES 2 powers on automatically when connected via USB-C to your computer. To power off, disconnect the USB-C cable or use the power button on the rear panel if applicable.
• Multi-Function LED Encoder: This large knob controls various parameters. Press it to cycle through functions like input gain and output volume. Rotate to adjust the selected parameter.
• Input/Output Metering: The bright LED meters provide visual feedback for your input and output levels. Aim for levels that are strong but do not consistently peak into the red.

3.2 Input and Gain Control

• MAX-HD Mic Preamps: The two mic preamps offer +75 dB of gain. Adjust gain using the Multi-Function LED Encoder or via the Universal Control app/Studio One.
• 48V fantomové napájení: Stiskněte tlačítko 48V button on the front panel to enable phantom power for condenser microphones. Ensure phantom power is only used with microphones that require it.
• Auto Gain: Stiskněte tlačítko Auto button to automatically set optimal gain levels for your connected microphones or instruments. This feature helps achieve recording-ready levels quickly.
• Vstupy přístroje: The front-facing instrument inputs are optimized for guitars and basses. Ensure the correct input is selected for your instrument.

3.3 Monitoring and Outputs

• Hlavní výstupy: Control the volume of your main studio monitors using the Multi-Function LED Encoder when the main output is selected.
• Sluchátkový výstup: Adjust headphone volume independently.
• Monitorování softwaru: The Quantum ES 2 relies on software monitoring through your Digital Audio Workstation (DAW). To hear your live input, you must enable input monitoring within your DAW (e.g., "Input Echo" in Cakewalk, or similar features in Studio One, Reaper, Pro Tools). This routes the input signal through the DAW to your outputs.
• Loopback Audio: This feature allows you to route audio from your computer's playback directly back into the interface for recording or streaming, simplifying the creation of monitor and streaming mixes.

3.4 Universal Control App Integration

The Universal Control app provides comprehensive control over your Quantum ES 2 settings from your computer or mobile device. This includes preamp gain, phantom power, and other critical functions, allowing for precise adjustments without interrupting your recording session.
