Description

Citronic Monolith Mk3 Column PA System with Bluetooth

The Citronic Monolith Mk3 is a compact, high-performance active PA system combining a 12-inch subwoofer and column speaker for full-range sound. With built-in Bluetooth and USB/SD playback, it delivers professional audio for solo performers, DJs, and event setups without the need for external gear.

Powerful and Efficient Amplification

Driven by a 400 + 100 W RMS class-D bi-amplifier, the Monolith Mk3 produces strong, controlled sound with clean bass, defined mids, and crisp highs. The integrated DSP ensures balanced output across all frequencies, giving you consistent results whether indoors or outdoors.

Smart Connectivity and Playback Options

Enjoy playback from multiple sources using the built-in USB/SD player or stream wirelessly via Bluetooth. The input section supports both microphone and line-level sources, with separate gain and subwoofer controls for precise sound shaping.

Quick Setup and Modular Flexibility

Supplied with an adjustable 35 mm pole and SPK link lead, the system assembles in minutes. Each unit can operate as a standalone mono setup or be paired with others for stereo or larger venue coverage, offering maximum flexibility for different applications.

Durable and Road-Ready Design

Built from 15 mm MDF and finished with a textured black polyurea coating, the Monolith Mk3 withstands demanding use while maintaining a professional appearance. Its rugged construction makes it a reliable choice for touring musicians, mobile DJs, and event organisers.
