The Studiomaster DIRECT 121MX is a powerful active column PA system combining a 12-inch subwoofer, wide-dispersion vertical array and integrated four-channel mixer in one portable package.

Designed for mobile DJs, musicians, entertainers, presenters and event venues, it provides the low-frequency performance required for music alongside the vocal clarity needed for live performances and speech. Its compact column arrangement also creates a cleaner, less obstructive setup than conventional speakers mounted on tripod stands.

Bluetooth audio streaming, adjustable reverb and comprehensive 24-bit digital signal processing allow the DIRECT 121MX to handle a wide variety of applications without always requiring additional sound equipment.

Powerful 12-Inch Subwoofer

The active subwoofer module contains a professional 12-inch driver mounted inside a wooden bass-reflex enclosure. With a rated power handling of 300W RMS, it delivers controlled low-frequency reinforcement for dance music, live instruments, backing tracks and general event audio.

Two 300W RMS Class D amplifier channels provide 600W RMS of available system amplification. The efficient amplifier design supplies power to both the subwoofer and vertical column while helping to keep the complete system compact and manageable.

An independent subwoofer level control provides quick access to the bass level, allowing the low-frequency output to be adjusted for different styles of music, room sizes and performance requirements.

Clear Vertical Array Projection

The column section contains six 3-inch midrange drivers and a dedicated 1-inch compression driver. This combination delivers detailed reproduction of vocals and instruments together with clear high frequencies.

A 120° horizontal by 30° vertical coverage pattern distributes sound across a broad audience area while controlling unnecessary vertical dispersion. This makes the system suitable for function rooms, conference venues, bars, restaurants, wedding venues and live performance spaces.

The wide horizontal coverage can also reduce the need to position several conventional speakers around smaller and medium-sized venues.

Integrated Four-Channel Mixer

A built-in four-channel mixer allows microphones, instruments and music sources to be connected directly to the DIRECT 121MX.

Two XLR and 6.35mm combination inputs can be switched between microphone and line-level operation. These connections accommodate microphones, keyboards, external mixers and other professional audio equipment.

A dedicated high-impedance 6.35mm input is provided for instruments such as electric and electro-acoustic guitars. Music can be played through the stereo RCA input or streamed wirelessly from a compatible Bluetooth device.

Adjustable input levels, microphone reverb and an independent subwoofer control make it possible to create a practical live mix directly from the system.

24-Bit DSP Sound Control

The integrated 24-bit DSP is operated through a clear display and single control encoder. Music, DJ and Speech operating modes provide useful starting points for different types of content.

Additional processing includes digital gain control, three-band equalisation, high-pass filtering, dual-channel limiting and storable presets. These controls help optimise the speaker for the source material and acoustic characteristics of the room.

The DSP also provides digital output delay for delay zones of up to 100 metres, adjustable in 0.25-metre increments. This enables the DIRECT 121MX to be aligned with other speakers when used as part of a larger distributed sound system.

Flexible Connections for Larger Systems

An XLR mix output provides a convenient way to send the combined audio signal to another compatible powered speaker or additional sound equipment.

A second speaker system can be connected when greater coverage or output is required. For larger performances, an external mixing desk can also be connected to provide additional inputs and centralised control.

Portable Modular Construction

The DIRECT 121MX separates into portable sections for transport and storage. The column and support section mount directly above the active subwoofer, removing the need for a conventional tripod speaker stand.

A protective cover for the subwoofer and a carry bag for the column sections are included. These help protect the components against dust, scratches and everyday wear while the system is being stored or transported between venues.

Frequently Asked Questions

Q: Is the Studiomaster DIRECT 121MX an active speaker system?

A: Yes. The amplification is built into the 12-inch subwoofer module and powers both the subwoofer and vertical column. A separate power amplifier is not required.

Q: Can the DIRECT 121MX be used without an external mixer?

A: Yes. The integrated four-channel mixer can accommodate microphones, line-level equipment, an instrument and a stereo music source. An external mixer is only necessary when more inputs or advanced mixing control are required.

Q: Can I connect microphones and instruments directly?

A: Yes. Two combination inputs accept microphone or line-level signals, while the dedicated high-impedance input is suitable for instruments such as electric and electro-acoustic guitars.

Q: Can two DIRECT 121MX systems be connected together?

A: Yes. The XLR mix output can be used to connect another compatible powered speaker system. An external mixer can also be used to control a pair from one central position.

Q: Does the DIRECT 121MX support Bluetooth audio?

A: Yes. Music can be streamed wirelessly from a compatible phone, tablet, laptop or other Bluetooth audio device.

Q: Are protective covers supplied with the system?

A: Yes. A protective cover for the active subwoofer and a carry bag for the column sections are included to make storage and transportation easier.
