- SCHAKELAAR: Draait de ampversterker aan of uit.
5. Instellen
- Plaatsing: Plaats de amplifier on a stable, level surface, ensuring proper ventilation. Do not cover the vent holes.
- Luidsprekeraansluiting: Connect your speaker cabinet(s) to the SPEAKER OUTPUT jacks using high-quality Speakon cables. Ensure the total impedance of your cabinets is not below 2.5 Ohms.
- Instrumentaansluiting: Connect your bass guitar to the INPUT jack using a standard 1/4" instrument cable. Select the appropriate PASSIVE or ACTIVE setting.
- Stroomaansluiting: Connect the supplied AC power cable to the POWER INPUT on the rear panel and then to a grounded AC outlet.
- Oorspronkelijke instellingen: Before powering on, set all EQ sliders to their center position, and turn the MASTER volume knob fully counter-clockwise.
- Inschakelen: Flip the POWER SWITCH to the 'ON' position. The amplifier will perform a brief startup sequence.
6. Gebruiksaanwijzing
6.1 Basisbediening
- After setup, slowly increase the MASTER volume to a desired listening level.
- Adjust the LEVEL knob to control the overall output volume.
- Use the 6-band Graphic EQ sliders to fine-tune your tone. Each slider boosts or cuts the specified frequency band.
6.2 Using the X Engine Distortion
- Druk op de X button to engage the distortion circuit.
- Pas de DRIJFVEER knob to control the amount of distortion.
- Gebruik de HPF En LPF knobs to set the frequency range for the distortion. The HPF determines where the distortion starts in the low end, and the LPF determines where it ends in the high end.
- De MENGEN knob allows you to blend the clean signal with the distorted signal, providing clarity and punch even with heavy distortion.
6.3 compressor
The built-in compressor can be engaged and adjusted using the COMP knob. Turning the knob clockwise increases the compression, adding sustain and evening out dynamics. This can be used on both clean and distorted tones.
6.4 IR Cabinet Simulation
The Microtubes X 900 includes three slots for Impulse Response (IR) cabinet simulations. These can be managed and loaded via the USB connection using the Darkglass Suite software.
