Figure 1: Front Panel Layout of the Pyle PYX-3X

The front panel of the PYX-3X provides access to all primary controls for adjusting crossover frequencies and output levels for low, mid, and high frequency bands. Refer to Figure 1 for a visual guide.

• POWER Indicator: This LED illuminates when the unit is powered on, indicating operational status.
• LOW PASS Frequency Control: Adjusts the upper frequency limit for the low-frequency output. The adjustable range is 50 Hz to 720 Hz.
• MID HIGH PASS Frequency Control: Adjusts the lower frequency limit for the mid-frequency output. The adjustable range is 50 Hz to 720 Hz, with a 'Flat' option to bypass the crossover for this band.
• 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. Rear Panel Connections

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

• RCA Input Jacks: Standard RCA connectors for connecting the main audio source (e.g., mixer, pre-amplifier).
• 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 amplifiers.
• 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 amplifiers.
• GND Screw: A grounding terminal for connecting an external ground wire to reduce hum and noise in the audio system.
• Voltage Selector Switch: A switch to select between 110V and 220V AC power input, matching the local electrical standard.
• AC Power Input: Connector for the detachable AC power cable.

7. Setup

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

1. Rack Mounting: 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 Selection: Before connecting the power cable, verify that the Voltage Selector Switch on the rear panel is set to the correct voltage for your region (110V or 220V). Incorrect voltage selection can damage the unit.
3. Audio Input Connection: Connect your main audio source (e.g., mixer, pre-amplifier) to the Input Jacks on the rear panel of the PYX-3X. You can use either the RCA or 1/4'' connectors.
4. Audio Output Connections: Connect the Low, Mid, and High Output Jacks of the PYX-3X to the corresponding input channels of your power amplifiers. For example, 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 amplifiers.
5. Grounding (Optional): If you experience hum or noise in your audio system, connect a ground wire from the GND Screw on the rear panel to a reliable earth ground point.
6. Power Connection: Once all audio connections are secure and the voltage is correctly selected, connect the supplied AC power cable to the AC Power Input on the rear panel and then to a suitable power outlet. The POWER indicator on the front panel should illuminate.

8. Operating Instructions

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

1. Initial Settings: Before playing audio, set all LEVEL Controls (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 LOW PASS control to define the upper frequency limit for your low-frequency speakers. Then, adjust the MID HIGH PASS and MID LOW PASS controls to define the frequency range for your mid-range speakers. Finally, adjust the HIGH PASS 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 LOW LEVEL, MID LEVEL, and HIGH LEVEL 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. Fine-Tuning: 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. Maintenance

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

• Cleaning: 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.
• Ventilation: Periodically check that the ventilation openings are clear of dust and debris. Ensure the unit has adequate space for airflow, especially if rack-mounted.
• Connections: 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.
• Storage: 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.

10. Troubleshooting

If you encounter issues with your PYX-3X, consult the following troubleshooting guide before seeking professional service.

• No Power:
  • Ensure the AC power cable is securely connected to both the unit and a working power outlet.
  • Verify that the Voltage Selector Switch on the rear panel is set to the correct voltage (110V or 220V).
  • Check the power outlet with another device to confirm it is functional.
• No Sound Output:
  • Confirm all audio input and output cables are correctly and securely connected.
  • Check the input source (mixer, pre-amp) to ensure it is sending an audio signal.
  • Ensure the LOW LEVEL, MID LEVEL, and HIGH LEVEL Controls on the PYX-3X are not set to minimum.
  • Verify that your power amplifiers are turned on and functioning correctly.
• Distorted Sound:
  • Reduce the input signal level from your audio source to prevent overloading the PYX-3X.
  • Lower the LEVEL Controls on the PYX-3X.
  • Check for impedance mismatches between the PYX-3X and connected amplifiers.
  • Review your crossover frequency settings to ensure they are appropriate for your speakers and not causing overlapping or gaps that lead to distortion.
• Hum or Noise in Audio:
  • Ensure the GND Screw on the rear panel is connected to a proper earth ground.
  • Check all audio cables for damage or loose connections. Try replacing cables if suspected faulty.
  • Move the PYX-3X away from other electronic devices (e.g., power supplies, computers) that may be causing electromagnetic interference.
