DLS PE4150 Performance Evolution four-channel power amplifier

4-channel power amplifier with control and musicality

The DLS Performance Evolution PE4.150 is a powerful 4-channel class D power amplifier, developed as the next step after DLS’s highly acclaimed P power amplifiers. It combines powerful power with stable control and a sound that is open, balanced and easy to live with over time. The PE4.150 is built for modern speaker systems and active solutions where predictable behavior and musicality are at least as important as output power. A power amplifier that lets the speakers do their job, without adding unnecessary character.

• 4-channel class D power amplifier
• 4x150W RMS in 2 Ohms, 4x100W RMS in 4 Ohms
• Bridgeable to 2 x 300 W RMS into 4 ohms
• Stable and controlled power delivery
• High-level input with Smart Load and Auto Turn On
• Adjustable high and low pass filters
• EMI-optimized design for modern cars
• Compact format with high efficiency

Substantial effect with calm demeanor

The PE4.150 delivers plenty of power, but does so in a controlled and predictable manner. The speakers are held firmly even when the volume is turned up, which provides better dynamics and clearer structure in the sound image. This makes the power amplifier equally suitable for traditional front systems as for more advanced, active installations.

Sound that holds the whole together

The sound character is tuned for natural reproduction. Details are clear without being harsh, and dynamics are there without being aggressive. The result is an open and balanced sound that works equally well at low and higher listening levels.

Adapted for modern car systems

Integration into today’s cars is a central part of the design. High-level input with Smart Load ensures that the power amplifier works stably even with original systems that monitor impedance. Automatic on and off simplifies installation and ensures that the system behaves consistently in everyday life.

Easy adjustment, clear results

With adjustable high- and low-pass filters, it is easy to adapt the power amplifier to the speakers and system configuration. The adjustments are logical and easy to understand, which makes adjustment quick and gives a result that is easy to fine-tune.
