1. Introducció
This instruction manual provides comprehensive guidance for the installation, operation, and maintenance of your HERTZ Mille Legend Series MLCX-2-TW3 2-Way Crossover Set. Please read this manual thoroughly before attempting any installation or operation to ensure proper functionality and to maximize the performance of your audio system. Retain this manual for future reference.
2. Producte acabatview
The HERTZ MLCX-2-TW3 is a high-performance 2-way passive crossover designed for car audio systems. It facilitates the creation of a bi-amplified system, allowing separate amplification channels for the woofer and tweeter. This configuration enhances power delivery and optimizes the performance of the MLK 1650.3 Legend system components. The crossover features advanced controls for fine-tuning the frequency response to match various vehicle acoustics and speaker placements.

3. Característiques clau
- Bi-Amplification Capability: Allows connection of two separate amplifier channels to drive woofer and tweeter independently, enhancing system power and performance.
- Mid-Contour Control: A two-position selector for managing the woofer cut-off frequency, enabling fine-tuning of the system's frequency response.
- Hi-Contour Control: A two-position selector for managing the tweeter cut-off frequency, allowing adjustment to suit different car acoustics and speaker placements.
- Hi-Boost Control: Selectable switch to improve the linearity of tweeter emission above 10kHz, particularly useful when tweeters are not positioned on-axis with the listener.
- Components d'alta qualitat: Features bi-metallized 160V polyester film capacitors with ultra-low DF for sound transparency, air wound inductors with pure copper-wire for high saturation threshold and low losses, and high power rating wirewound resistors for stability.
- Construcció robusta: Designed for durability and reliable performance in automotive environments.
4. Configuració i instal·lació
Una instal·lació correcta és crucial per a un rendiment òptim. Es recomana que la instal·lació la realitzi un professional qualificat. Assegureu-vos que la bateria del vehicle estigui desconnectada abans de començar qualsevol cablejat.
4.1 Connexions de cablejat
The MLCX-2-TW3 crossover is designed to integrate into a bi-amplified system. This means separate amplifier channels will connect to the crossover for the woofer and tweeter sections.
- Ampentrada de lifier: Connect the dedicated amplifier channels for the woofer and tweeter to the respective input terminals on the crossover.
- Sortida de woofer: Connect the woofer speaker to the designated woofer output terminals.
- Sortida del tweeter: Connect the tweeter speaker to the designated tweeter output terminals.
Assegureu-vos que totes les connexions estiguin ben fixades i degudament aïllades per evitar curtcircuits.

4.2 Control Adjustments
The MLCX-2-TW3 features several controls to tailor the sound to your preference and vehicle's acoustics.
- Mid-Contour: This two-position selector adjusts the woofer's cut-off frequency. Experiment with both positions to find the setting that best integrates the woofer with the mid-range frequencies in your specific vehicle environment.
- Hi-Contour: Similar to Mid-Contour, this two-position selector adjusts the tweeter's cut-off frequency. Use this to fine-tune the high-frequency response, considering speaker placement and desired sound characteristics.
- Hi-Boost: Activate this switch if your tweeters are not directly aimed at the listening position (off-axis). It provides a boost above 10kHz to compensate for high-frequency roll-off, ensuring a more linear tweeter emission.
Adjust these controls incrementally and listen carefully to the changes in sound reproduction to achieve your preferred audio balance.

5. Instruccions de funcionament
Once installed and configured, the MLCX-2-TW3 operates passively, dividing the audio signal between the woofer and tweeter based on the selected crossover points. The primary operation involves setting the Mid-Contour, Hi-Contour, and Hi-Boost switches during the initial setup phase to achieve the desired sound profile. No further user interaction is typically required during normal operation.
- Ensure all audio components (head unit, amplifiers) are powered off before making any adjustments to the crossover switches.
- After making adjustments, power on your audio system and evaluate the sound. Repeat adjustments as necessary until optimal sound is achieved.
6. Manteniment
The HERTZ MLCX-2-TW3 crossover is designed for long-term, maintenance-free operation. No specific user maintenance is required beyond ensuring clean and secure connections.
- Keep the crossover free from dust and moisture.
- Periodically check wiring connections for tightness and corrosion.
- Eviteu exposar la unitat a temperatures extremes o a la llum solar directa durant períodes prolongats.
7. Solució De Problemes
If you experience issues with your MLCX-2-TW3 crossover, refer to the following common troubleshooting steps:
| Problema | Causa possible | Solució |
|---|---|---|
| No sound from woofer or tweeter | Connexió de cablejat fluixa o incorrecta. Amplifier not powered on or faulty. | Check all wiring connections to the crossover and speakers. Verify amplifier power and functionality. |
| So distorsionat | Incorrect gain settings on amplifier. Damaged speaker. Crossover settings not optimal. | Ajustar amplifier gain settings. Inspect speakers for damage. Re-evaluate Mid-Contour and Hi-Contour switch positions. |
| Imbalanced sound (e.g., too much treble) | Hi-Contour or Hi-Boost settings are too aggressive for the listening environment. | Adjust the Hi-Contour switch. If Hi-Boost is active, try deactivating it to see if the balance improves. |
If problems persist after attempting these solutions, contact HERTZ customer support or a qualified car audio technician.
