4. Configurazione e installazione
4.1. Impedance Selection (4 Ohm / 8 Ohm)
The CRX 3003K crossover is designed to work with both 4 Ohm and 8 Ohm speaker configurations. The impedance is selected via a jumper on the circuit board. Ensure the jumper is correctly positioned to match the impedance of your speaker system for optimal performance and to prevent damage.

4.2. Collegamenti elettrici
Connetti il tuo amplifier output and speaker drivers to the appropriate terminals on the crossover board. Observe correct polarity (+ and -) for all connections to ensure proper phase alignment and sound reproduction.
- IN (+ / -): Connect these terminals to the output of your audio amppiù vivace.
- W (+ / -): Connect these terminals to your woofer (low-frequency driver).
- M (+ / -): Connect these terminals to your midrange speaker (mid-frequency driver).
- T (+ / -): Connect these terminals to your tweeter (high-frequency driver).
Nota: Assicurati sempre il tuo amplifier is turned off before making or changing any connections to prevent electrical shock or damage to your equipment.
5. Principi operativi
Once connected, the LASE CRX 3003K crossover passively filters the full-range audio signal from your amplifier. It directs frequencies below 375 Hz to the woofer, frequencies between 375 Hz and 3000 Hz to the midrange speaker, and frequencies above 3000 Hz to the tweeter. This division ensures that each speaker driver receives only the frequencies it is designed to reproduce efficiently, leading to clearer sound, reduced distortion, and improved overall system performance.
6. Manutenzione
The LASE CRX 3003K is a passive component and requires minimal maintenance. Keep the unit in a dry, dust-free environment. Avoid exposing it to extreme temperatures, direct sunlight, or moisture. Periodically inspect connections to ensure they remain secure. Do not attempt to open or modify the unit, as this may void any potential warranty and could lead to damage.
7. Risoluzione Dei Problemi
- Nessun suono da un altoparlante:
- Controllare tutti i collegamenti elettrici per verificare la corretta polarità e il contatto sicuro.
- Verify the speaker driver itself is functioning correctly by testing it with another known good source (if safe to do so).
- Suono distorto:
- Ensure the impedance jumper setting on the crossover matches your speaker's impedance.
- Confirm that the total power handling of your speakers and amplifier is within the limits of the crossover (600 Watts max).
- Controllare che non vi siano collegamenti allentati o cavi danneggiati.
- Suono sbilanciato:
- Double-check all positive and negative connections for correct polarity. Incorrect polarity can cause phase issues.
If problems persist, consult a qualified audio technician.
