Opsætning
Follow these steps to set up your Citronic U-PAD mixer:
- Strømtilslutning: Connect the supplied USB A to B cable to the USB port on the rear of the mixer and to a suitable USB power source (e.g., a computer USB port or a USB power adapter). The mixer will power on.
- Indgangsforbindelser:
- Mono Channels (MIC/INST 1 & 2): Connect microphones via XLR or instruments/line-level devices via 1/4" jack to the combo inputs.
- Stereo Line Input (CH 3-4 IN): Connect stereo line-level devices (e.g., keyboards, media players) using 1/4" jack cables to the L/MONO and R inputs.
- Udgangsforbindelser: Connect the MAIN OUT L and R XLR outputs to your amphøjttaler, aktive højttalere eller optageinterface.
- Hovedtelefonforbindelse: Connect your headphones to the PHONES 1/4" jack for monitoring.
- USB Audio Connection: If using the mixer with a computer for recording or playback, connect the USB A to B cable to your computer. The mixer should be recognized as an audio device without requiring special drivers on most operating systems (Windows, macOS).
Betjeningsvejledning
Understanding the controls of your U-PAD mixer is key to achieving optimal sound:
Channel Controls (Mono Channels 1 & 2, Stereo Channel 3-4)
- GEVINST: Adjusts the input sensitivity for each channel. Set this to achieve a strong signal without clipping (indicated by the PK LED).
- HIGH/LOW EQ: These knobs control the treble (HIGH) and bass (LOW) frequencies for each channel. Use them to shape the tone of your audio.
- PAN (Mono Channels): Adjusts the position of the mono signal in the stereo field (left to right).
- BAL (Stereo Channel): Balances the left and right signals of the stereo input.
- BIND: Styrer udgangsvolumen for hver enkelt kanal til hovedmixet.
- +48V Phantom Power: For mono channels, press the +48V button to supply phantom power to condenser microphones connected via XLR. Ensure microphones are compatible before activating.
- IMPED (Impedance Switch): For mono channels, switch between MIC (low impedance) and INST-HI-Z (high impedance) for optimal input matching.
Hovedsektionens kontroller
- MAIN OUT: Controls the overall volume of the main stereo output.
- TELEFON: Justerer lydstyrken for hovedtelefonudgangen.
- USB/2TK Input: This section allows routing of the digital audio input from the USB connection. The input can be routed to the main output or to the headphones for monitoring.
- NIVEAUMÅLER: The LED meter displays the output level of the main mix. Aim for levels that are strong but do not consistently peak into the red.
Opretholdelse
Proper care and maintenance will ensure the longevity of your Citronic U-PAD mixer:
- Rensning: Disconnect the power before cleaning. Use a soft, dry cloth to wipe the surface of the mixer. Do not use abrasive cleaners, waxes, or solvents.
- Opbevaring: Når mixeren ikke er i brug i længere perioder, skal den opbevares køligt og tørt, væk fra direkte sollys og ekstreme temperaturer.
- Støvbeskyttelse: Hold mixeren dækket til, når den ikke er i brug, for at forhindre støvophobning, som kan påvirke fadere og knapper.
- Undgå væsker: Never allow liquids to spill onto or into the mixer, as this can cause severe damage to internal components.
- Håndteres med forsigtighed: Undgå at tabe mixeren eller udsætte den for kraftige stød.
Fejlfinding
If you encounter issues with your U-PAD mixer, refer to the table below for common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| No sound output from main mix | Main OUT volume is too low; individual channel volume is too low; incorrect cable connection; amphøjttalere slukket eller på lydløs. | Increase MAIN OUT volume. Increase individual channel VOL. Check all audio cable connections. Ensure amplifier/speakers are on and unmuted. |
| No sound from a specific channel | Channel VOL is too low; GAIN is too low; input device not connected or off; incorrect IMPED setting; PAN/BAL set to one side. | Increase channel VOL and GAIN. Check input device and cable. Adjust IMPED switch. Center PAN/BAL knob. |
| Forvrænget lyd | GAIN or VOL levels are too high (clipping); impedance mismatch; faulty cable. | Reduce GAIN and channel VOL until PK LED no longer illuminates. Check IMPED setting. Try a different cable. |
| USB audio not recognized by computer | USB cable not properly connected; computer USB port issue; operating system audio settings. | Ensure USB cable is securely connected. Try a different USB port on your computer. Check your computer's sound settings to ensure the U-PAD is selected as the input/output device. |
| No phantom power (+48V) to microphone | +48V button not engaged; microphone not compatible with phantom power; faulty XLR cable. | Press the +48V button. Ensure your microphone requires and is compatible with phantom power. Test with a different XLR cable. |
