DLS Compact 6 Channel DSP with Class AB Amplifier - Designed & Engineered in Sweden Overview A 4 in, 6 out DSP amplifier that offers precise system tuning, flexible control and the warm, natural DLS sound in the car. A compact 6 channel digital signal processor with an integrated Class AB power amplifier. Signal processing and amplification are housed in a single chassis, with a focus on the typical DLS character: warm, natural sound with low listening fatigue. A 24 bit / 192 kHz Cirrus Logic platform handles the DSP. Each channel can be adjusted with a 31 band equaliser, flexible crossover filters and time alignment in 1 cm steps. This provides the tools needed to correct speaker response, deal with the car interior and establish a stable centre image at the listening position. PA4.6DA is built to integrate cleanly with modern OEM systems. A 4 channel high-level input with Smart Load Circuitry presents a suitable load to factory head units with impedance monitoring, and additional inputs include RCA, optical digital and Bluetooth 5.1. Six RCA DSP outputs are available for external amplifiers. Configuration is carried out via a Windows based USB interface, and up to ten presets can be stored in the internal memory.
