Studiomaster DIRECT 121MX Column Array PA System with Active 12" Sub & DSP Mixer
The Studiomaster DIRECT 121MX is a complete, all-in-one column array PA system designed for musicians, DJs, presenters, and event organisers who need professional-quality sound without the complexity of a traditional multi-component setup. Built around a 12" active subwoofer and a column speaker housing six 3" mid-range drivers plus a 1" compression driver, it delivers clear, wide-dispersion audio with genuine low-end punch — ideal for venues holding up to 150 people.
Unlike traditional PA systems that require separate amplifiers, crossovers, and processing, the 121MX packages a 4-channel DSP mixer, 24-bit processing, and Bluetooth 5.0 connectivity directly into the subwoofer unit. Whether you're running a wedding, church service, school event, or corporate presentation, this system sets up in minutes and sounds like it costs far more.
Key Features
Wide-dispersion column array
Six 3" mid-range drivers paired with a 1" compression driver produce a wide, even sound spread across your audience — eliminating the hot spots and dead zones common with traditional box speakers.
Powerful 12" active subwoofer
The bass-reflex 12" sub delivers tight, controlled low frequencies that fill a room without muddiness — ideal for music with real bottom-end presence.
Built-in 4-channel DSP mixer
No separate mixer needed. Connect two microphones, a guitar or instrument, and a Bluetooth/RCA source simultaneously. Each mic input has independent gain and reverb control.
Three DSP modes: Music / DJ / Speech
Switch between dedicated voicings for the occasion. Speech mode ensures vocal clarity for presentations; DJ mode adds punch for dance music; Music mode delivers a balanced profile for live bands.
Bluetooth 5.0 with True Wireless Stereo (TWS)
Stream wirelessly from any phone or tablet with a strong, stable Bluetooth 5.0 connection. TWS allows two 121MX units to pair together for stereo coverage.
Digital delay for delay zones
Run fill speakers or delay zones up to 100 metres from the main system, configurable in 0.25m increments directly from the DSP display.
Fast assembly
The unique internal connection system means the column and subwoofer snap together quickly — no tools, no loose cables between units.
Who is the Studiomaster DIRECT 121MX best suited for?
The 121MX hits a sweet spot between compact portability and serious audio performance. It's particularly well-suited to:
- Mobile DJs playing private parties, weddings, and corporate events where a lightweight rig matters as much as sound quality
- Live acoustic or solo performers who need vocals, guitar, and backing track inputs in a single system
- Houses of worship where clear speech intelligibility and wide room coverage are priorities
- Schools and educational venues running assemblies, presentations, or small performances
- Conference and AV professionals looking for a self-contained system with minimal setup time
If you're covering audiences of 50–150 people in small to medium-sized indoor venues, the 121MX offers remarkable performance for the price point.

Frequently Asked Questions
How many people can the Studiomaster DIRECT 121MX cover?
The 121MX is designed for audiences of roughly 50 to 150 people in small to medium indoor venues. For larger events or outdoor use, running two units in TWS stereo mode will significantly extend coverage.
Does the 121MX need a separate mixer?
No. The system includes a built-in 4-channel DSP mixer with mic, instrument, RCA, and Bluetooth inputs. For basic to intermediate setups, no external mixer is required.
Can I use two DIRECT 121MX systems together?
Yes. Bluetooth 5.0 TWS (True Wireless Stereo) allows two units to be paired for stereo output. The XLR line output also lets you daisy-chain or feed additional speakers.
What's the difference between the 121MX and the 101MX?
The 121MX features a larger 12" subwoofer compared to the 10" sub in the 101MX, providing greater low-frequency output and headroom for louder environments and music with heavier bass content.
Is the Studiomaster DIRECT 121MX suitable for outdoor use?
The 121MX is primarily designed for indoor use. For outdoor events, the system can still perform well in sheltered or smaller outdoor settings, though in open-air environments you may want to consider pairing two units or adding additional coverage.
