The Crown XFMR-4 and XFMR-8 are sophisticated, rack-mountable transformers designed to provide impedance matching between amplifier outputs and constant voltage loudspeakers. These transformers enable amplifiers that lack direct 70Vrms or 100Vrms output capability to drive distributed speaker systems operating at those voltages, making them an essential component in various commercial and industrial audio installations.
**Features:**
The Crown XFMR-4 and XFMR-8 are built to cater to different channel requirements, with the XFMR-4 offering four channels and the XFMR-8 providing eight channels of impedance matching. This flexibility allows these units to be seamlessly integrated into a wide range of audio setups, ensuring compatibility with distributed systems. The primary purpose of these transformers is to facilitate the connection of amplifiers to constant voltage loudspeakers, thus broadening the applications of amplifiers without direct constant voltage capabilities.
One of the standout features of the XFMR-4 and XFMR-8 is their ability to provide 70Vrms and 100Vrms output when used exclusively with the ComTech DriveCore Series of amplifiers. This ensures that even amplifiers not inherently designed for constant voltage operation can be effectively utilized in distributed audio systems. The inclusion of jumper cables with each unit further simplifies the integration process, allowing for quick and efficient incorporation of the XFMR unit with a ComTech DriveCore amplifier.
**Specifications:**
In terms of connectivity, the XFMR-4 and XFMR-8 are equipped with pluggable barrier block connectors that accept wire gauges up to 14 AWG. This ensures secure and reliable connections, critical for maintaining the integrity of audio signals in professional installations. The frequency response of these transformers is impressive, with a range of +/-1.0dB from 70Hz to 15kHz, ensuring high-fidelity audio reproduction across a broad spectrum of frequencies.
The insertion loss of the transformers is minimal, ensuring that the audio signal remains strong and clear even after impedance matching. At 70VAC, the insertion loss is rated at dB max, which is indicative of the unit’s efficiency in signal transmission. The transformers are also designed to handle significant power input, with a maximum input rating of 32Vrms/125W, making them suitable for high-power audio applications.
**Physical Characteristics:**
The Crown XFMR-4 and XFMR-8 are built with practicality in mind. They are rack-mountable, with dimensions of 19″ x 1.72″ x 15.6″ (48.3cm x 4.4cm x 39.7cm), making them compatible with standard audio racks. This rack-mountable design ensures that the transformers can be easily integrated into existing audio equipment setups, saving space and simplifying installation. Despite their robust construction, the units maintain a manageable weight, with the XFMR-8 weighing in at 23.6lbs (10.7kg). This balance of durability and ease of handling is essential for professional audio environments where equipment needs to be both reliable and practical to manage.
**Conclusion:**
In conclusion, the Crown XFMR-4 and XFMR-8 transformers are essential tools for audio professionals looking to expand the capabilities of their amplifiers in distributed audio systems. Their ability to provide impedance matching and support for 70Vrms and 100Vrms outputs makes them versatile and valuable additions to any audio setup. The user-friendly features, such as pluggable connectors and included jumper cables, ensure that these transformers can be quickly and easily integrated with ComTech DriveCore amplifiers, providing a reliable solution for high-quality, constant voltage audio distribution. With their robust construction and efficient performance, the Crown XFMR-4 and XFMR-8 are well-suited to meet the demands of modern commercial and industrial audio applications.
