2 2.1 Getting Started Level Setting Procedure (Full-Range) 2 Getting Started StudioLive™ AI-Series Loudspeaker Owner’s Manual Before you begin, here are a few general rules of thumb: •• Always make sure your loudspeakers are powered off when making connections. •• Do not allow your inputs to clip. Watch the Clip LED on the back of your loudspeaker. When this LED illuminates, it indicates that the analogto-digital converters are in danger of being overdriven.
2 2.1 Getting Started Level Setting Procedure (Full-Range) StudioLive™ AI-Series Loudspeaker Owner’s Manual 3. If you’re using the StudioLive full-range loudspeaker as a mixer, connect a microphone to the Mic input with a standard XLR cable. 4. Connect your line-level source (such as a PreSonus StudioLive digital mixer) to the Line input. The Line input is a combo connection that accepts a balanced ¼” TRS or XLR cable.
2 2.1 Getting Started Level Setting Procedure (Full-Range) StudioLive™ AI-Series Loudspeaker Owner’s Manual 6. Power on your StudioLive loudspeaker. 7. Turn the Speaker level knob to the 12 o’clock position. 8. While speaking into the microphone, use the Mic level knob to adjust the microphone level. Be sure that you are not standing directly in front of the loudspeaker while doing this, as doing so could result in feedback.
2 2.2 Getting Started Level Setting Procedure (18sAI) StudioLive™ AI-Series Loudspeaker Owner’s Manual 10. Both the Microphone and Line inputs should be set so that the green Signal LED is illuminated most of the time, but the red Clip LED illuminates only with the highest transient peaks or not at all. 11. If more output level is required, turn the Speaker level knob clockwise. This is the master level control for your loudspeaker. It controls the mixed signal of the Mic and Line inputs. 12.
2 2.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual Getting Started Level Setting Procedure (18sAI) LEFT 3. Turn the Sub level knob on your 18sAI counterclockwise to the lowest position. 4. Connect your line-level source (e.g., a StudioLive mixer) to the Line inputs. This is a combo jack that accepts a balanced ¼” TRS or XLR plug. If you are connecting a stereo source, the left side should be connected to Input 1, and the right side should be connected to Input 2. 5.
2 2.2 Getting Started Level Setting Procedure (18sAI) StudioLive™ AI-Series Loudspeaker Owner’s Manual 6. Power on your line-level source. 7. Power on your 18sAI. 8. Power on your StudioLive AI full-range loudspeakers. 9. Turn the Speaker level knob on your full-range loudspeakers to the 12 o’clock position. 10. Turn the Sub level knob on your 18sAI to the 12 o’clock position. This is unity gain.
2 2.2 Getting Started Level Setting Procedure (18sAI) StudioLive™ AI-Series Loudspeaker Owner’s Manual 11. Turn the Line level knob on your full-range loudspeakers to the fully clockwise position. 12. The line-level inputs should be set so that the green Signal LED is illuminated most of the time, but the red Clip LED illuminates only with the highest transient peaks or not at all. If your line-level source is clipping the inputs on your 18sAI, you will need to turn down the source’s output level. 13.

4 4.1 System Configuration Recognizing Problem Rooms 4 System Configuration StudioLive™ AI-Series Loudspeaker Owner’s Manual StudioLive AI-series full-range loudspeakers are designed to reproduce an input signal with extreme fidelity, maintaining near-flat frequency and phase response at all levels up to the threshold of clipping. However, the performance of any loudspeaker will be influenced by the acoustics of the space in which they operate.
4 4.1 System Configuration Recognizing Problem Rooms StudioLive™ AI-Series Loudspeaker Owner’s Manual 4.1.1 Vertical Coverage It is important to keep in mind that vertical coverage is just as important as horizontal coverage. If you are using a ground-stack approach with pole mounts, make sure your coverage matches the listening plane. Suspension of speakers will provide even further control. Each StudioLive AI-series full-range loudspeaker features dual-position pole mounts.
4 4.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Delay Systems 4.1.3 Maintain a High Direct-to-Reverberant Ratio Another way a room interacts with sound waves is through reflectivity. Like most room anomalies, reflections can be good and bad. Consider the effect of a cathedral’s reflections on a choir or a piano. This type of reverberation (reverb) is quite desirable. But not all reverb is good reverb. Reflections can also cause comb filtering.
4 4.2 System Configuration Delay Systems StudioLive™ AI-Series Loudspeaker Owner’s Manual 4.2.1 Delay Basics Delay speakers allow you to run the main speakers at a lower volume, as they relieve the mains of handling high- and mid-frequency content for part of the space. As a speaker is pushed harder, the edges of its frequency response begin to distort, so by easing the demands on the mains, delay systems increase fidelity sonically, as well as mechanically.
4 4.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Delay Systems Outside. Outdoors, you are trying to maintain level as the noise floor of the crowd begins to be at equal level to the PA in the intelligibility range. When working outside, the delay system is used to overcome outdoor noise, including (but not limited to) crowd murmur, concessions, generators, tractors, babies, etc.
4 4.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Delay Systems 2M. Select this setting when the subwoofer is about two meters from the full-range loudspeaker—typical when the full-range system is on the stage and the subwoofer is on the floor. A delay of about 5.9 ms is introduced to the signal that is output through the subwoofer amplifier.
4 4.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Delay Systems 4.2.3 Real-World Delay System Example ZONE 3 SL312AI MAINS SL315AI Source ZONE 2 SL328AI ZONE 1 SL328AI The goal in a complicated system with loudspeakers distributed throughout the venue is to delay each satellite system to its counterpart in the main system (e.g., the left front fill to the left FOH loudspeaker). •• Delay the main system relative to the source on stage.
4 4.2 System Configuration Delay Systems StudioLive™ AI-Series Loudspeaker Owner’s Manual help determine the best final location for your loudspeaker system. If your speakers are sitting on the floor, you can expect a certain amount of halfspace loading. If you are using your speakers as floor wedges, you might want to experiment with using the High Pass Filter to reduce low energy. In some cases, this might improve intelligibility.
4 4.2 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Delay Systems 4.2.7 LCR Systems An LCR system is a stereo system with a center speaker added. This configuration allows panning and adds depth to the acoustic image. This type of system will provide more control than a basic stereo system and is ideal in situations where music and speech intelligibility are equally important. 4.2.
4 4.3 System Configuration Rigging and Safety 4.3 Rigging and Safety StudioLive™ AI-Series Loudspeaker Owner’s Manual This section has been created as a reference for safe rigging and mounting practices. It is not an installation tutorial. PreSonus StudioLive AI-Series loudspeakers are professional products and are not intended for consumer use.

4 4.3 System Configuration Rigging and Safety StudioLive™ AI-Series Loudspeaker Owner’s Manual 4.3.2 Ground Stacking StudioLive AI-series full-range loudspeakers have four nonskid rubber feet on the bottom for upright front-of-house use and four nonskid rubber feet on one side for stage-monitor applications. If your application is primarily portable, PreSonus loudspeakers can be easily ground stacked and configured for a variety of venues.
4 4.3 StudioLive™ AI-Series Loudspeaker Owner’s Manual System Configuration Rigging and Safety 4.3.4 Suspending the Loudspeaker A minimum of three suspension points must be used per speaker to safely suspend StudioLive AI loudspeakers. Two wires fixed symmetrically to the front of the cabinet to hold the weight and one wire attached to the back for tilt will satisfy this requirement.
4 4.3 System Configuration Rigging and Safety StudioLive™ AI-Series Loudspeaker Owner’s Manual 4.3.4 Precautions StudioLive AI-series loudspeakers, like all electrical devices, must be protected from liquids or excessive moisture. They are not designed for outdoor use during inclement weather.
