Rockboard LM 4

RockBoard LM 4 is a compact four-channel line mixer designed for stage and studio use. It combines four mono line-level input signals into a single mono output, making it a practical sub-mixer for keyboards, playback sources and other line devices.

Each input channel has its own amplifier and individual volume control, allowing precise balancing of connected sources. The mixer is built to deliver low-noise, professional audio quality at all volume levels.

Its robust metal enclosure and compact format make the LM 4 easy to integrate into both portable and permanent setups. It is a convenient solution when you want to preserve channels on the main mixing console.
