Crown XFMR-4 Four-channel Transformer

Description

The Crown XFMR-4 Four-Channel Transformer is a rack-mountable accessory designed to allow professional power amplifiers to drive constant-voltage loudspeaker systems such as 70V and 100V distributed audio networks. It provides four independent transformer channels for proper impedance matching, making it ideal for commercial installations where multiple speakers are connected over long cable runs. The XFMR-4 is commonly used to add constant-voltage capability to amplifiers that do not have built-in 70V/100V outputs.

Key Features

• Four Independent Channels: Supports four channels of impedance-matching transformer outputs

• 70V / 100V Operation: Enables connection to constant-voltage distributed speaker systems

• Amplifier Compatibility: Allows standard low-impedance amplifiers to power distributed audio networks

• Rack-Mount Design: Fits a standard 19-inch rack and occupies 1U of rack space

• Professional Connections: Uses secure terminal block connectors for reliable speaker wiring

• Wide Frequency Response: Maintains clear audio performance across the speech and music range

• Durable Construction: Built for long-term reliability in commercial and installed sound environments
