D 20:4
2,000 Watt Amplifier with 4 Flexible Output Channels, LAKE Digital Signal Processing and Digital Audio Networking for Installation Applications

D 20:4L Combines 2000 W of Flexible Power with the Latest LAKE DSP, DANTE Digital Audio Networking and Advanced System Integrity Monitoring.
The D 20:4L is based on the same foundation of robust, high-power amplifier technologies as our renowned PLM Series – an amplifier platform with a proven record of reliability and sonic performance on the world’ s most grueling concert tours and in high-profile, large-scale installations.
With the D 20:4L, those same core technologies have been updated and refocused to provide the ultimate solution for the most demanding digitally networked installed sound applications – in stadia, arenas, theme parks, performing arts centers, racecourses and other large commercial sound installations.
