1.2 About This Manual
This manual covers hardware features and functions for all three full-range
AI loudspeakers (312AI, 315AI, and 328AI) as well as the companion 18sAI
subwoofer. We suggest that you use the manual to familiarize yourself with
the features, applications, and connection procedures for your StudioLive
AI-series loudspeakers before trying to set up and operate them.
Except for low-frequency driver configuration and some technical specifications
(such as weight, frequency response, and maximum SPL), the features and
functions of the three full-range models are the same. In many respects, the
functions of the 18sAI are also the same. Whenever possible these features and
functions will be described for the entire line. Unless preceded by “full-range,”
the term “loudspeaker” will refer to both full-range models and the subwoofer.
Throughout this manual you will find Power User Tips highlighting
unique aspects of StudioLive AI-series loudspeakers, as well as
explanations of various audio terms. In addition, you will find tutorials
that cover the basics of room acoustics and speaker placement.
Thank you, once again, for buying our product. We are confident
that you will enjoy your StudioLive AI loudspeakers!

2 Getting Started
2.1 Level Setting Procedure (Full-Range)
2 Getting Started
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. Overdriving
the converters will cause digital distortion, which sounds terrible.
• Your full-range loudspeaker provides attenuation control only for the speaker
and line levels. If you are not getting adequate volume with these controls
turned all the way up (0 dB), make sure that your mixer is properly gainstaged and that you are using enough loudspeakers for your application.
Your PA and studio equipment should be powered on in the following order:
• Sound sources (keyboards, direct boxes, microphones,
etc.) connected to your mixer
• Mixer
• StudioLive AI-series Loudspeakers
When it’s time to power down, your system should be turned off in the reverse order.
Now that you know what not to do, let’s get some audio going! The following
level-setting tutorials cover best practices that can be applied to nearly every
application. The first tutorial covers level setting for the full-range models
only; the second tutorial describes proper level setting for a system that
includes one 18sAI subwoofer and two full-range AI-series loudspeakers.
StudioLive™ AI-Series Loudspeaker
Owner’s Manual
2.1 Level Setting Procedure (Full-Range)
1. With the power switch in the Off position, connect the locking IEC plug to
the IEC socket connection on the back of the loudspeaker and plug it into a
grounded AC outlet or surge protector.
Power User Tip: While a locking IEC cable is ideal for permanent installation, be
careful that this cable cannot be tripped over in ground-stacked applications, as this
is a toppling risk.
2. Turn the Mic, Line, and Speaker level knobs fully counterclockwise, to the
lowest position.

2.1 Level Setting Procedure (Full-Range)
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.
Power User Tip: If you are running a stereo system, connect the Left output of
your mixer to the Left loudspeaker’s line input, and the Right output to the Right
loudspeaker’s line input.

5. Power on your line-level source.

2.1 Level Setting Procedure (Full-Range)
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
StudioLive™ AI-Series Loudspeaker
Owner’s Manual
loudspeaker while doing this, as doing so could
result in feedback. If you are not using the Mic
input, it is recommended that you leave this knob
in the Off position so as not to introduce noise
into your signal path.
9. With audio playing through your line-level source, turn the Line level knob
until you have achieved a comfortable listening volume. If you are not using
the Line input, it is recommended that you leave this knob in the -24 dB
position so as not to introduce noise into your signal path.

2 Getting Started
2.2 Level Setting Procedure (18sAI)
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. If you are using the input mixer of one loudspeaker to connect
a microphone and a line-level source, or if you are running
a mono system, connect the Mix Out from the loudspeaker
to which your sources are connected to the line input of
the second loudspeaker and repeat steps 9-11.
StudioLive™ AI-Series Loudspeaker

2.2 Level Setting Procedure (18sAI)
1. With the power switch in the Off position, connect the locking IEC plug to
the IEC socket connection on the back of each loudspeaker and plug it into
a grounded AC outlet or surge protector.
2. Turn the Mic, Line, and Speaker level knobs on your full-range loudspeakers
fully counterclockwise to the lowest position.

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. Connect Output 1 of your 18sAI to the left full-range loudspeaker
and Output 2 of your 18sAI to the right full-range loudspeaker.

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.
10
2 Getting Started
2.2 Level Setting Procedure (18sAI)
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. If more high-frequency output level is required, turn the Speaker level knob
clockwise on your full-range loudspeakers. In most cases, the level should
be set the same on both loudspeakers.
StudioLive™ AI-Series Loudspeaker
Owner’s Manual
14. Adjust the Sub level control on your 18sAI to balance the low-frequency
content level to taste.
15. The full-range loudspeakers offer a highpass filter centered at 100 Hz. With
or without this filter engaged, the full-range loudspeakers are time-aligned
to pair with the 18sAI to create a true 4-way system. Experiment with
engaging and disengaging this filter to get the desired effect. Without the
filter engaged, your system will provide bigger low-frequency content.
Engaging the filter will provide a more linear frequency response. In either
case, please remember that engaging/disengaging the highpass filter will
also adjust the time-alignment of the speaker and it will mute momentarily
until all filters and timing settings have been loaded in the DSP.
