Crown XFMR-4 Four Channel Transformer vs Crown Audio XLS 1502 Two-channel 525W Power Amplifier
The Crown XFMR-4 is a passive impedance-matching transformer for integrating standard amplifiers into 70V/100V distributed speaker systems, while the Crown XLS 1502 is an active, self-powered two-channel amplifier designed for direct speaker driving in live and studio settings. Choose the XFMR-4 if you need to adapt existing amplifiers to constant-voltage systems; choose the XLS 1502 if you need a compact, self-contained power amp for direct performance or installation use.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
Can these products work together?
Yes. The XLS 1502 can supply audio input to the XFMR-4, allowing you to convert the amplifier's standard output into 70V/100V distributed speaker system levels. The XFMR-4 is designed to work with Crown amplifiers including the XLS series.
What's the key difference in application?
The XFMR-4 is a passive integration tool for existing amplifiers feeding constant-voltage systems (commercial buildings, schools, stadiums). The XLS 1502 is a ready-to-use powered amplifier for direct speaker connection in live sound, studios, and mobile applications.
Which is better for a small live venue?
The XLS 1502 is the simpler choice—it's self-powered, weighs under 11 lb, and provides 525W of clean output ready to drive speakers without additional components. The XFMR-4 requires a separate amplifier, making it less portable.
How do their frequency responses compare?
The XFMR-4 specifies flat response ±1.0 dB from 70 Hz to 15 kHz. The XLS 1502 description emphasizes clean, undistorted output and DriveCore efficiency across the audible spectrum but does not publish specific frequency response figures.
