Studiomaster Direct 121M 12-Inch Column PA System - Black

Studiomaster Direct 121M 12-Inch Column PA System

The Studiomaster Direct 121M Column PA System is a self-powered three-way sound system delivering 600W RMS, up to 2400W peak power, and a manufacturer-rated maximum output of 122 dB. Its 12-inch bass-reflex subwoofer combines with six 3-inch midrange drivers and a 1-inch compression driver for portable full-range sound reinforcement.

Available in Black and White, the Direct 121M suits mobile DJs, live performers, presentations, houses of worship, corporate events, and other applications that benefit from fast setup and wide audience coverage. The column system provides 120 x 30-degree dispersion, while internal connections allow the speaker sections and height-adjusting column to assemble without separate audio cables. A universal 100-240V power supply supports operation across a broad range of venues.

An integrated four-channel mixer handles microphone, line, instrument, RCA, and Bluetooth sources without requiring a separate console for straightforward setups. The onboard 24-bit DSP provides equalization, gain adjustment, selectable presets, high-pass filtering, limiting, and digital delay up to 100 meters. Bluetooth also supports TWS, or True Wireless Stereo, for pairing two compatible systems as left and right channels.
