1. Einleitung
The MXR M87 Bass Compressor is designed to bring studio-quality compression to your bass rig. This pedal offers a comprehensive set of controls to fine-tune your sound, from subtle dynamic control to pronounced compression effects. Featuring CHT™ Constant Headroom Technology, it ensures clear performance and ample headroom. The transparent compression allows your full dynamic range to pass through until the signal reaches the compression threshold, which is visually indicated by ten bright gain-reduction status LEDs. Encased in a durable, lightweight aluminum housing, the M87 is built for the road.
Hauptmerkmale:
- CHT™ Constant Headroom Technology for clear, clean performance.
- True bypass circuitry for uncolored tone when disengaged.
- Ten highly visible gain-reduction status LEDs for precise visual feedback.
- Transparent compression that preserves dynamic range until threshold.
- Durable, lightweight aluminum housing.
2. Bedienelemente und Funktionen im Überblickview
The MXR M87 Bass Compressor features a complete array of controls to shape your bass tone effectively.

Steuerknöpfe:
- ATTACKE: Adjusts how quickly the compressor reacts to the input signal. Higher settings result in a slower attack, allowing more of the initial transient to pass through.
- FREISETZUNG: Controls how quickly the compressor returns to its uncompressed state after the signal drops below the threshold. Higher settings result in a slower release.
- VERHÄLTNIS: Determines the amount of compression applied once the signal exceeds the threshold. Higher ratios mean more aggressive compression.
- EINGANG: Sets the input level of your bass signal into the compressor. This control also affects when the compression threshold is met.
- AUSGABE: Regelt die Gesamtlautstärke des Pedals.
LED-Anzeigen:
- GAIN REDUCTION-LEDs: Ten bright LEDs provide visual feedback on the amount of gain reduction being applied in real-time. This helps in precisely setting the compression.
- STATUS-LED: Indicates whether the pedal is engaged (on) or in true bypass mode (off).
Jacks and Footswitch:

- Eingangsbuchse: Connect your bass guitar or the output of another pedal to this 1/4-inch input.
- OUTPUT-Buchse: Connect this 1/4-inch output to your ampVerstärker oder der Eingang des nächsten Effektpedals in Ihrer Signalkette.
- Netzanschluss: Connect a 9V DC power adapter (not included) to this jack.
- Fußschalter überbrücken: Toggles the effect on and off. The pedal features true bypass, ensuring your tone remains unaffected when the pedal is disengaged.
3. Einrichtung
Follow these steps to set up your MXR M87 Bass Compressor:
- Verbinde deine Bassgitarre mit dem/der/dem EINGANG jack of the M87 using a standard 1/4-inch instrument cable.
- Verbinden Sie AUSGABE jack of the M87 to your ampVerstärker oder das nächste Pedal in Ihrer Signalkette mit einem weiteren 6,35-mm-Instrumentenkabel.
- Connect a 9V DC power adapter (not included) to the LEISTUNG jack on the side of the pedal. Ensure the power supply meets the pedal's requirements (9V DC, center-negative).
- Schalten Sie Ihr amplifier and adjust its volume to a suitable level.

4. Bedienungsanleitung
The MXR M87 Bass Compressor is designed for intuitive operation. Experiment with the controls to find the perfect compression for your playing style and musical context.
Grundlegende Bedienung:
- Engage the pedal by pressing the BYPASS-Fußschalter. The STATUS LED will illuminate.
- Start with all control knobs (ATTACK, RELEASE, RATIO, INPUT, OUTPUT) at their 12 o'clock positions.
- Play your bass and adjust the EINGANG knob until the GAIN REDUCTION LEDs show consistent activity, indicating that the compressor is engaging.
- Passen Sie die VERHÄLTNIS knob to control the intensity of the compression. Lower ratios provide subtle smoothing, while higher ratios create a more pronounced, squashed effect.
- Feinabstimmung der ANGRIFF Und FREIGEBEN knobs to shape the transient response and sustain characteristics. Faster attack settings will compress the initial pluck more, while slower attacks allow more punch. Faster release settings will return to uncompressed sound quickly, while slower releases provide longer sustain.
- Verwenden Sie die AUSGABE knob to match the volume of the compressed signal to your bypassed signal, or to provide a boost if desired.
Tips for Tone Shaping:
- For subtle peak limiting and dynamic control, use a lower RATIO setting (e.g., 2:1 or 4:1) with moderate INPUT.
- To achieve a more sustained and punchy tone, increase the RATIO and adjust ATTACK to be slightly slower, allowing the initial transient to cut through before compression engages.
- The GAIN REDUCTION LEDs are crucial for understanding how the compressor is reacting to your playing. Aim for consistent, but not excessive, gain reduction for natural-sounding compression.

6. Wartung
To ensure the longevity and optimal performance of your MXR M87 Bass Compressor, follow these maintenance guidelines:
- Reinigung: Reinigen Sie die Außenseite des Pedals mit einem weichen, trockenen Tuch. Vermeiden Sie Scheuermittel oder Lösungsmittel, da diese die Oberfläche beschädigen können.
- Lagerung: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove any batteries to prevent leakage.
- Verbindungen: Periodically check all input/output jacks and power connections for any signs of wear or corrosion. Ensure cables are securely plugged in during use.
- Stromversorgung: Always use a regulated 9V DC, center-negative power supply to prevent damage to the pedal.
7. Fehlerbehebung
If you encounter issues with your MXR M87 Bass Compressor, refer to the following common troubleshooting steps:
- Kein Ton:
- Überprüfen Sie alle Kabelverbindungen (Instrument, ampVerstärker, Leistung).
- Stellen Sie sicher, dass die Stromversorgung korrekt angeschlossen ist und funktioniert.
- Vergewissern Sie sich, dass Ihr Instrument und amplifier are working correctly by bypassing the pedal.
- Check the OUTPUT knob setting; ensure it is not turned down completely.
- Unerwünschte Geräusche/Brummen:
- Stellen Sie sicher, dass Sie ein hochwertiges, isoliertes Netzteil verwenden.
- Prüfen Sie auf defekte Kabel.
- Try the pedal in a different location to rule out electrical interference.
- Adjust the INPUT and OUTPUT knobs to avoid overdriving your ampLifier oder andere Pedale.
- Compression Not Engaging:
- Erhöhen Sie den EINGANG knob setting. The GAIN REDUCTION LEDs should light up when compression is active.
- Stellen Sie sicher, dass VERHÄLTNIS knob is set above its minimum value.
