Smart Speaker Modes

StageSource® is designed to be the world’s most versatile loudspeaker system for musicians. Using six powerful DSP-based Smart Speaker modes, the StageSource L3m output is optimized for a variety of performance scenarios including front-of-house PA, floor monitor, personal PA, keyboard backline, acoustic guitar backline, or with a multi-effects guitar processor as a high-performance electric guitar speaker system. Onboard accelerometer and pole mount sensors automatically detect the speaker’s orientation and set the Smart Speaker mode accordingly.

Powerful 1,400-watt, Three-way Design

The 1,400-watt, 3-way, tri-amped speaker system and a dual-braced tour-grade plywood enclosure combine to deliver astounding power and reliability. The innovative multi-function design enables the L3m to be the perfect loudspeaker in a wide variety of applications including floor or stage-stacked, pole-mounted, horizontal as a floor monitor, Virtual Tilt-back for instrument backline or flown with the integrated M10 suspension points for installation.

Orientation and Pole-mount Sensors

StageSource L3m uses an internal accelerometer, optical sensors and DSP to accelerate setup and optimize the sound of your system. Based on the information the system detects, it selects the right Smart Speaker mode for the application, and automatically adjusts its performance.

For example, when the unit is powered on in a horizontal position, it automatically selects Floor Monitor mode. This mode provides a slight reduction in low-frequency content to counteract coupling when placing the speaker on the floor.

If any "backline" mode is chosen (Keyboard, Acoustic Guitar, Electric Guitar), the L3m then checks its orientation (via the accelerometer) and looks to see if it is on a pole (via the pole sensor). If the speaker is vertical and not on a pole, the L3m activates Virtual Tilt-back which optimizes the speaker tuning to achieve an upward tilt to its main axis. This helps to aim the sound upward towards the performer's ears when the speaker is placed on the ground. If the speaker is on a pole, it doesn't activate Virtual Tilt-back because it assumes that the speaker is elevated and aimed in the desired direction.

Integrated Feedback Suppression

Since feedback can ruin a performance, StageSource L3m uses intelligent 12-band feedback suppression to identify the problem frequencies and adjust levels without affecting the overall sound.

L3m feedback suppression continuously analyzes the audio signal, identifying frequencies that have the characteristics of feedback (steady frequencies with few overtones, rising in amplitude) and then applies a narrow notch filter to remove the offending frequency. L3m feedback suppression can remove up to 12 independent feedback frequencies. You can set the feedback analyzer to one of three modes, depending on how aggressively the analyzer will seek out potential feedback frequencies.

Multi-function Design and Scalability

Multi-function design combined with powerful Smart Speaker modes and digital networking provides true scalability whether you’re using a single L3m as a standalone PA or multiple StageSource loudspeakers as main PA, monitors and backline. Add StageSource L3s subwoofers and customize a configuration to meet your live sound or installation needs.

Road-ready Construction

StageSource L3m is ready for whatever the road can throw at it. The robust enclosure is constructed of dual-braced, heavy-duty plywood, and the tour-grade steel grille features protective screen backing that shields the drivers from impact damage.

If you need to fly the speakers, each StageSource L3m features four professional M10 suspension points with a pull-back.
