• MID LOW PASS Frequency Control: Adjusts the upper frequency limit for the mid-frequency output. The adjustable range is 1 KHz to 8 KHz, with a 'Flat' option to bypass the crossover for this band.
• HIGH PASS Frequency Control: Adjusts the lower frequency limit for the high-frequency output. The adjustable range is 1 KHz to 8 KHz.
• LOW LEVEL Control: Adjusts the output level (volume) of the low-frequency band.
• MID LEVEL Control: Adjusts the output level (volume) of the mid-frequency band.
• HIGH LEVEL Control: Adjusts the output level (volume) of the high-frequency band.

6. Collegamenti del pannello posteriore

The rear panel provides all necessary input and output connections for integrating the PYX-3X into your audio system.

• Jack di ingresso RCA: Standard RCA connectors for connecting the main audio source (e.g., mixer, pre-amplificatore).
• 1/4'' Input Jacks: Alternative 1/4-inch (6.35mm) TRS/TS connectors for connecting the main audio source.
• RCA Output Jacks (Low, Mid, High): Standard RCA connectors for sending the processed low, mid, and high frequency signals to respective power amplificatori.
• 1/4'' Output Jacks (Low, Mid, High): Alternative 1/4-inch (6.35mm) TRS/TS connectors for sending the processed low, mid, and high frequency signals to respective power amplificatori.
• Vite GND: A grounding terminal for connecting an external ground wire to reduce hum and noise in the audio system.
• Voltage Selettore: A switch to select between 110V and 220V AC power input, matching the local electrical standard.
• Ingresso alimentazione CA: Connector for the detachable AC power cable.

7. Impostazione

Follow these steps to properly set up your Pyle PYX-3X Electronic Crossover Network.

1. Montaggio su rack: The PYX-3X is designed for installation in a standard 1U (1.75 inches) rack space. Secure the unit using appropriate rack screws. Ensure sufficient space for ventilation.
2. Voltage Selezione: Before connecting the power cable, verify that the Voltage Selettore sul pannello posteriore è impostato sul volume correttotage per la tua regione (110 V o 220 V). Vol erratotagLa selezione può danneggiare l'unità.
3. Connessione ingresso audio: Connect your main audio source (e.g., mixer, pre-amplifier) ​​al Jack di ingresso on the rear panel of the PYX-3X. You can use either the RCA or 1/4'' connectors.
4. Collegamenti di uscita audio: Collegare il Low, Mid, and High Output Jacks of the PYX-3X to the corresponding input channels of your power amplificatori. Ad esempioample, connect the 'Low' output to the amplifier driving your subwoofers, 'Mid' to the amplifier for mid-range speakers, and 'High' to the amplifier for tweeters. Use either RCA or 1/4'' connectors as appropriate for your amplificatori.
5. Messa a terra (opzionale): If you experience hum or noise in your audio system, connect a ground wire from the GND Vite on the rear panel to a reliable earth ground point.
6. Collegamento elettrico: Once all audio connections are secure and the voltage is correctly selected, connect the supplied AC power cable to the Ingresso alimentazione CA on the rear panel and then to a suitable power outlet. The POWER indicator on the front panel should illuminate.

8. Istruzioni per l'uso

Proper operation of the PYX-3X involves careful adjustment of crossover frequencies and output levels to achieve optimal sound reproduction.

1. Impostazioni iniziali: Before playing audio, set all Controlli di LIVELLO (Low, Mid, High) on the front panel to their minimum positions. Set the Frequency Control Knobs to a neutral or starting position (e.g., mid-point of their range).
2. Adjusting Crossover Frequencies: Play a familiar audio track. Gradually adjust the PASS BASSO control to define the upper frequency limit for your low-frequency speakers. Then, adjust the MID HIGH PASS E MID LOW PASS controls to define the frequency range for your mid-range speakers. Finally, adjust the ALTO PASSAGGIO control to define the lower frequency limit for your high-frequency speakers. The goal is to achieve a smooth, seamless transition between frequency bands without noticeable gaps or overlaps.
3. Using 'Flat' Mode: The Mid (High Pass) and Mid (Low Pass) frequency controls include a 'Flat' setting. When engaged, this setting bypasses the crossover for that specific band, allowing the full frequency range to pass through. This can be useful for specific system configurations or testing.
4. Adjusting Output Levels: Once the crossover frequencies are set, slowly increase the BASSO LIVELLO, LIVELLO MEDIO, E ALTO LIVELLO controls. Adjust these individually to balance the volume of each frequency band, ensuring a cohesive and balanced soundstage. Avoid setting levels too high, which can lead to distortion.
5. Ritocchi: Listen critically to various types of music or audio content and make small adjustments to both frequency and level controls until the desired sound quality is achieved.

9. Manutenzione

Regular maintenance helps ensure the longevity and optimal performance of your PYX-3X.

• Pulizia: Use a soft, dry, lint-free cloth to clean the exterior of the unit. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish and internal components.
• Ventilazione: Periodically check that the ventilation openings are clear of dust and debris. Ensure the unit has adequate space for airflow, especially if rack-mounted.
• Connessioni: Occasionally check all audio and power cable connections to ensure they are secure and free from corrosion. Loose connections can lead to signal loss or noise.
• Magazzinaggio: If the unit will not be used for an extended period, disconnect it from power and store it in a cool, dry environment, away from direct sunlight and extreme temperatures.
