3. Hvad er der i æsken

Upon unpacking your NUX Melvin Lee Davis NBP-5, please ensure all items are present:

• NUX Melvin Lee Davis NBP-5 Bass Preamp Pedal
• USB-kabel
• Brugervejledning (dette dokument)

4. Opsætning

4.1 Strømtilslutning

Connect a 9V DC (center negative) power adapter to the 'DC 9V' input jack on the rear of the pedal. Ensure the adapter provides at least 30mA. The pedal does not operate on batteries.

4.2 Lydforbindelser

The NBP-5 offers various input and output options for flexible integration into your setup.

Figure 1: Rear panel connections of the NUX NBP-5 Bass Preamp Pedal.

• INPUT: Connect your bass guitar to this 1/4-inch input jack.
• DI UD: This XLR output provides a balanced signal for connecting to a mixing console or audio interface. Use the 'PRE/POST' switch to select whether the signal is affected by the pedal's EQ and effects (POST) or is a dry signal (PRE). The 'LIFT/GND' switch helps eliminate ground hum.
• VED: This 1/4-inch output provides a buffered dry signal of your bass, unaffected by the pedal's processing. Useful for sending a clean signal to another pedal or tuner.
• UD: This 1/4-inch output provides the processed signal from the pedal, suitable for connecting to a bass amplifier eller andre effekter.
• AUX IN: Connect an external audio player (e.g., smartphone) to this 1/8-inch input for practice along with backing tracks.
• HOVEDTELEFON UD: Connect headphones to this 1/8-inch output for silent practice or monitoring. The headphone output is linked to the DI Out, so activating DI IR simulation will affect the headphone output.

4.3 USB-forbindelse

Connect the Micro B USB port on the rear of the pedal to your computer using the provided USB cable. This connection allows for:

• Firmwareopdateringer.
• Software control via the NUX editor software.
• Loading custom Impulse Response (IR) files.
• Using the pedal as a USB audio interface for recording.

5. Operating the NBP-5

The NBP-5 features intuitive controls for shaping your bass tone. Familiarize yourself with the knobs and switches for optimal use.

• KØRE: Controls the amount of gain/overdrive in the drive channel.
• BAS: Justerer lavfrekvensresponsen.
• I midten: Justerer mellemfrekvensresponsen.
• FREKVENS: Selects the center frequency for the MIDDLE knob, allowing you to target specific mid-range frequencies.
• DISKANT: Justerer diskantresponsen.

5.2 Fodkontakter

• DRIVE Footswitch: Engages or disengages the drive channel.
• ON/OFF fodkontakt: Activates or bypasses the main preamp section of the pedal.

• DI OUT IR: Toggles the Impulse Response cabinet simulation for the DI OUT.
• OUT IR: Toggles the Impulse Response cabinet simulation for the 1/4-inch OUT.
• FØR/POST: Determines if the DI OUT signal is taken before (PRE) or after (POST) the pedal's EQ and effects.
• LIFT/GND: Lifts the ground connection for the DI OUT to eliminate ground loop hum.

5.4 Impulse Response (IR) Loader

The NBP-5 features an integrated IR loader. You can select from built-in IRs or load your own custom 1024-point WAV IRs via the NUX editor software. The IRs can be independently applied to the DI OUT and 1/4-inch OUT using their respective toggle switches.

5.5 Støjreduktion

The built-in noise reduction helps eliminate unwanted hum and hiss, especially when using high-gain settings or single-coil pickups. Adjust the decay and threshold parameters via the NUX editor software for optimal performance.
