Behringer NR300 Noise Reducer Pedal Instruction Manual

1. Introduktion

The Behringer NR300 Noise Reducer Pedal is designed to effectively eliminate unwanted noise and hum from your audio signal without compromising your instrument's tone. This pedal is suitable for various musical applications, particularly with instruments prone to noise, such as those with single-coil pickups.

2. Nøglefunktioner

• Effective noise and hum elimination without altering tone.
• Preserves original attack and envelope, maintaining playing dynamics.
• Dedicated Threshold and Decay controls for precise noise reduction.
• Mute mode for silent instrument switching.
• Additional Send/Return loop for noise suppression of external effects units.
• Blue status LED indicates effect status and battery check.
• Operates on a 9V battery or optional BEHRINGER PSU-SB DC power supply.
• Electronic On/Off switch ensures signal integrity in bypass mode.

3. Kontrol og stik

Familiarize yourself with the various controls and connection points on your NR300 pedal.

3.1. MODE Switch

This switch selects between STUM og REDUKTION tilstande.

• STUM: When activated, the pedal acts as a silent on/off switch for your instrument.
• REDUKTION: Engages the noise reduction circuit, allowing you to control the noise gate parameters.

3.2. THRESHOLD Knob

Controls the level at which the noise reduction circuit activates. Turn clockwise to increase the threshold, meaning only louder signals will pass through. Turn counter-clockwise to decrease the threshold, allowing quieter signals to pass.

3.3. DECAY Knob

Adjusts how quickly the noise reduction circuit closes after the signal drops below the threshold. A higher decay setting (clockwise) results in a slower fade-out, while a lower setting (counter-clockwise) provides a faster, more abrupt cut-off.

3.4. IN Jack

Connect your instrument or the output of a preceding effects pedal to this 1/4" TS input.

3.5. OUT Jack

Connect this 1/4" TS output to your amplifier or the input of the next effects pedal in your chain.

3.6. SEND Jack

This 1/4" TS output is part of the external effects loop. Connect this to the input of an effects unit you wish to place within the noise reduction loop (e.g., a distortion pedal).

3.7. RETURN Jack

This 1/4" TS input is part of the external effects loop. Connect the output of the effects unit from the SEND loop to this jack.

3.8. Fodkontakt

Activates or deactivates the pedal's effect. The blue status LED indicates the pedal's active state.

3.9. DC IN-stik

Connect an optional 9V DC power supply (not included) to this jack. Ensure the power supply has a center-negative polarity.

4. Opsætning

4.1. Strømforsyning

The NR300 can be powered by a 9V battery or an optional 9V DC power supply (BEHRINGER PSU-SB recommended, not included).

4.1.1. Batteriinstallation

To install a 9V battery, press the hinges at the front of the footswitch to open the pedal. Insert the 9V battery, ensuring correct polarity. Close the pedal securely.

4.1.2. External Power Supply

If using an external power supply, connect it to the DC IN jack. Disconnect the input cable from the IN jack when not in use to conserve battery life if operating on battery power.

4.2. Tilslutning af pedalen

Tilslut dit instrument til IN jack of the NR300. Connect the UD jack of the NR300 to your amplifiers input eller den næste pedal i din signalkæde.

4.3. Using the Send/Return Loop

For optimal noise reduction, especially with high-gain effects, utilize the Send/Return loop. Connect the SENDE jack to the input of your noisy effects pedal (e.g., distortion, overdrive). Connect the output of that effects pedal to the TILBAGE jack of the NR300. This allows the NR300 to gate the noise generated by the effects unit itself.

5. Betjening

The NR300 offers two primary modes of operation: Reduction and Mute.

5.1. Reduction Mode

Indstil MODE skifte til REDUKTION. In this mode, the pedal functions as a noise gate. Adjust the GRÆNSEVÆRDI og FORFALD knobs to achieve the desired noise reduction without cutting off your notes prematurely.

• Start med GRÆNSEVÆRDI knob at its minimum setting.
• While playing, slowly increase the GRÆNSEVÆRDI until the unwanted noise (hum, hiss) is eliminated when you stop playing.
• Juster FORFALD knob. A shorter decay (counter-clockwise) will cut off the sound more abruptly, while a longer decay (clockwise) will allow notes to fade out more naturally before the gate closes. Find a balance that suits your playing style and instrument.

5.2. Mute-tilstand

Indstil MODE skifte til STUM. In this mode, the pedal acts as a silent kill switch. Pressing the footswitch will completely mute your instrument's signal, useful for silent tuning or switching instruments.

5.3. Status-LED

The blue LED indicates the pedal's status:

• På: Effect is active.
• Slukket: Effect is bypassed.
• Dim or Flashing: Indicates a low battery. Replace the 9V battery promptly.

6. Vedligeholdelse

To ensure the longevity and optimal performance of your Behringer NR300 pedal, follow these maintenance guidelines:

• Hold pedalen ren og fri for støv og snavs. Brug en blød, tør klud til rengøring.
• Undgå at udsætte pedalen for ekstreme temperaturer, fugtighed eller direkte sollys.
• Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• If operating on battery power, remove the battery if the pedal will not be used for an extended period to prevent leakage.
• Håndter alle kabler og stik forsigtigt for at undgå skader.
