Description
AudioCenter D4.2K DSP Power Amplifier
The AudioCenter D4.2K is a four-channel Class D DSP power amplifier in the AudioCenter D Series. It is built for professional audio systems that need rack amplifier power, DSP control, and a clean match for passive loudspeakers.
Experienced DJs, production users, venue techs, and church or school audio buyers usually know when they are stepping into a real amplifier-based system instead of powered boxes. SMS Car Audio can help confirm whether the D4.2K is the right AudioCenter match for your speakers, zones, rack layout, cable needs, source gear, and future expansion.
