DLS Performance Advantage PA4.6DA 4-channel amplifier with DSP

.

The DLS Performance Advantage PA4.6DA is a 4-channel analog amplifier with integrated 6-channel DSP and 4x 25/50 W RMS power.

A compact 6-channel digital signal processor with integrated class AB power amplifier. Signal processing and amplification are located in one chassis with an emphasis on the typical DLS character. Warm, natural sound with low listening fatigue.

The DSP is provided by a 24-bit / 192 kHz Cirrus Logic platform. Each channel can be adjusted with a 31-band equalizer, flexible crossover filters and time alignment in 1 cm steps. This provides the tools needed to correct speaker response, process the car interior and create a stable central image at the listening position.

The PA4.6DA is designed for easy integration with modern OEM systems. The 4-channel high-level input with intelligent load circuitry provides a suitable load for factory head units with impedance monitoring. Other inputs include RCA, optical digital input and Bluetooth 5.1. Six RCA DSP outputs are available for external amplifiers. Configuration is via a USB interface for Windows and up to ten presets can be stored in the internal memory.
