5. Betjeningsvejledning
5.1 Understanding the Signal Path
The Microtubes X Ultra splits your bass signal into two distinct paths: a low-frequency path and a high-frequency path. The low-frequency path remains clean and can be compressed, while the high-frequency path is processed with distortion. The Lavpasfilter (LPF) og Højpasfilter (HPF) controls determine the frequency range for each path. The LAVT NIVEAU og HØJT NIVEAU controls adjust the volume of these respective paths, allowing you to blend them to achieve your desired tone.
5.2 Using the Graphic Equalizer
The 6-band graphic equalizer allows for precise tonal sculpting. Each fader provides ±12dB of boost or cut at its designated frequency (250Hz, 500Hz, 1.5kHz, 3kHz). Adjust these faders to fine-tune your overall sound or to compensate for room acoustics.
5.3 DI Output Functionality
The balanced XLR DI output provides a clean, low-impedance signal suitable for direct connection to mixing consoles, audio interfaces, or PA systems. This is ideal for live performance and studio recording, ensuring a consistent and high-quality signal.
5.4 Headphone Output and AUX In
The headphone output allows for silent practice. Connect your headphones to the 1/8-inch jack. The AUX IN allows you to connect an external audio source, such as a smartphone or MP3 player, to play along with backing tracks through your headphones.
6. Pleje og vedligeholdelse
To ensure the longevity and optimal performance of your Microtubes X Ultra pedal, follow these guidelines:
- Rensning: Brug en blød, tør klud til at rengøre pedalens yderside. Undgå slibende rengøringsmidler eller opløsningsmidler.
- Strømforsyning: Always use a regulated 9V DC, center-negative power supply. Using an incorrect power supply can damage the unit and void the warranty.
- Miljø: Protect the pedal from extreme temperatures, humidity, and direct sunlight. Avoid dropping the unit or exposing it to excessive force.
7. Fejlfinding
If you encounter issues with your Microtubes X Ultra, consider the following common troubleshooting steps:
- Ingen lyd:
- Sørg for, at alle kabler (instrument, ampstrømforsyning) er tilsluttet korrekt.
- Verify the power supply is correctly connected and functioning.
- Tjek, at amplifier and instrument volumes are turned up.
- Ensure the pedal is not in bypass mode if you expect an effect.
- Uønsket støj/brummen:
- Brug en isoleret strømforsyning af høj kvalitet.
- Kontroller for defekte kabler.
- Ensure proper grounding in your setup.
- Distortion Issues:
- Juster HIGH DRIVE kontrollere.
- Tjek Højpasfilter (HPF) setting to ensure the desired frequencies are being distorted.
