Crown XFMR-4 Four Channel Transformer vs Crown Audio XLS 1002 Two-channel 350W Power Amplifier
The Crown XFMR-4 is a passive transformer for integrating standard amplifiers into constant-voltage distributed speaker systems, while the XLS 1002 is an active power amplifier designed for direct speaker drive in live and studio applications. Choose the XFMR-4 if you need to adapt existing amplifiers to 70V/100V systems; choose the XLS 1002 if you need a standalone, portable amplifier with built-in processing.

Why choose Crown XFMR-4 Four Channel Transformer
- ✓ Enables integration of standard amplifiers into 70Vrms/100Vrms distributed speaker systems
- ✓ Compact single-rackspace design with four independent channels of impedance matching
- ✓ Flat frequency response (+/– 1.0 dB, 70 Hz–15 kHz) with minimal insertion loss (≤1.0 dB)
- ✓ Straightforward installation with pluggable barrier block connectors accepting up to 14 AWG wire
Why choose Crown Audio XLS 1002 Two-channel 350W Power Amplifier
- ✓ Standalone 350W amplifier (2400W bridged at 4Ω) requiring no external transformer
- ✓ Ultra-lightweight and portable at under 11 lb with Crown's DriveCore 2 Class D efficiency
- ✓ Advanced DSP features including bandpass filter per channel, PureBand crossover, and Peakx limiters
- ✓ Multiple input options (XLR, 1/4", RCA) with selectable input sensitivity for flexible signal routing
Frequently asked questions
What is the primary use case for each product?
The XFMR-4 converts standard amplifier outputs to 70Vrms or 100Vrms for distributed speaker systems in larger facilities. The XLS 1002 is a standalone power amplifier for driving speakers directly in live venues, studios, or mobile applications.
Can I use these products together?
Yes, in theory: the XLS 1002 could serve as the amplifier source feeding the XFMR-4 transformer to drive a constant-voltage system. However, the XLS 1002 is designed for direct speaker drive and includes its own crossover and limiting, so this combination would be redundant for most applications.
Which is better for portable/mobile use?
The XLS 1002 is significantly more portable at under 11 lb and is purpose-built for gigging and live performance. The XFMR-4 is a rack-mount transformer requiring integration with an external amplifier, making it less suitable for mobile setups.
What frequency response and distortion performance do they offer?
The XFMR-4 maintains flat response (+/– 1.0 dB, 70 Hz–15 kHz) with ≤1.0 dB insertion loss. The XLS 1002 emphasizes low distortion and high headroom through its DriveCore 2 Class D design, though specific frequency response and THD figures are not detailed in the provided information.
