Know before you buy
RPM allows you to distribute the total 20,000 W of power unevenly across the four channels. This means you can allocate more power to high-demand subwoofers while assigning less to high-frequency drivers, maximizing the efficiency of the amplifier based on your specific speaker load.
Yes, the unit features dual redundant Dante networking and is also compatible with AES67. It provides an 8x8 I/O configuration, making it easy to integrate into complex, professional digital audio infrastructures.
Absolutely. The amplifier allows you to store up to 100 user presets internally. This feature is ideal for touring professionals who need to quickly recall specific loudspeaker tunings or system configurations at different venues.
The PLM 20K44 is managed via the Lake Controller software, which runs on the Windows platform. This software provides full access to the DSP features, including crossovers, delay, and compression, as well as system-wide monitoring.
The amplifier is designed with a wide operating voltage range of 70–265 V AC. This flexibility, combined with its comprehensive protection suite, makes it highly reliable for touring applications where power quality can be inconsistent.
When using the AES input, the system maintains a low latency of 1.61 ms. This ensures high-performance, real-time audio processing suitable for the most demanding live sound environments.
