CROWN brand 4-channel audio converter for 70/100V signal conversion, model XFMR-4

CROWN XFMR-4 4-channel audio converter for 70/100V signal conversion with DriveCore systems

• The XFMR-4 audio converter is a professional-grade converter unit designed to provide high-efficiency compatibility with ComTech DriveCore™ series amplifiers, enabling easy and reliable operation of systems on 70V or 100V constant voltage distribution lines. The XFMR-4 is designed to facilitate the integration of amplifiers not directly equipped with constant voltage into commercial audio distribution systems, while maintaining clear, distortion-free, and loss-free audio performance. It features a compact design at only 1U in height and can be directly mounted in acoustic racks. It also comes with jumper cables for quick connection to DriveCore amplifiers.

Technical description:

• The XFMR-4 audio converter is a four-channel converter used to modulate the signal from amplifiers to operating levels suitable for a constant voltage distribution (70V or 100V). It is primarily based on integration with ComTech DriveCore amplifiers. The converter offers optimal compatibility in terms of efficiency and frequency accuracy, minimizing signal loss to a maximum of only 1.0 dB when operating at 70VAC, making it an ideal choice for systems requiring high-quality sound with balanced distribution.

Technical specifications:

• Number of channels: 4 channels
• Operating type: Converts to 70V/100V (when used with ComTech DriveCore amplifiers)
• Frequency range: ±1.0 dB from 70 Hz to 15 kHz
• Input Loss: Less than or equal to 1.0 dB at 70VAC
• Maximum input: 32V RMS / 125W
• Connectors: Pluggable barrier block (supports wires up to 14 AWG)
• Dimensions (Width x Height x Depth): 19 x 1.72 x 15.6 inches (48.3 x 4.4 x 39.7 cm)
• Weight: 17 lbs (7.7 kg)

Key features:

• Reliable conversion from a standard amplifier to 70V/100V operation
• Fully compatible with the ComTech DriveCore series
• Clear audio performance with low signal loss
• Compact 1U design for easy shelf mounting
• Includes jumper cables for quick connection without the need for complicated modifications.

Product summary:

• The XFMR-4 audio converter is the ideal choice for organizations that use amplifiers that do not support direct 70V/100V operation, as it allows these amplifiers to be easily and efficiently integrated into professional audio distribution systems without affecting sound quality or overall performance.

Additional features:

• Operating power up to 125 watts per channel
• Improved frequency response for mid-range and high-frequency audio coverage
• Robust construction and high durability for continuous commercial operation
• Compatible with standard wires up to 14 AWG

Applications used for the product:

• Commercial audio systems: For converting signals to 70/100 volts in shopping malls, hotels, and hospitals.
• Mosque and educational institution systems: to provide balanced sound coverage
• Industrial facilities: For transmitting sound in factories and warehouses via long-range distribution systems.
• Entertainment and sports facilities: For clear sound delivery in theaters or gyms using DriveCore amplifiers

Summary and final advice:

If you are using ComTech DriveCore amplifiers and need to integrate them into 70V or 100V audio distribution systems, then Audio converter The XFMR-4 is the ideal solution to meet this need efficiently and reliably. It offers a seamless conversion without sacrificing sound quality or installation complexity, making it a smart investment for professional audio systems.
