StudioLive™ AI-Series
SL312 3-way active loud-
speakers combine high
power and advanced coaxial
configuration with the most pow-
erful DSP engine ever built into
a compact PA system. Through
seamlessly integrated software,
StudioLive AI speakers can be
set-up, adjusted and continuous-
ly monitored via wired or wireless
remote control using Windows®,
OSX® or iPad®.
Advanced 24-bit floating point
digital signal processing.
StudioLive AI-Series loud-
speakers were tuned by master
speaker designer Dave Gunness
using Fulcrum Acoustic’s trade-
marked Temporal Equalization™
algorithms. Previously possible
only using powerful outboard
rack processors, TQ™ is used to
manage horn reflection, linear
time and amplitude anomalies
correction, performance
contouring, and dynamic and
excursion limiting.
The result is a coaxial speaker
system with
•Crisper stereo image
•Greater soundstage depth
•More separation between
complex mix components
•Increased resistance
to feedback
•More seamless transitions
between distributed
loudspeakers
•Less fatiguing listening
experience at very high SPLs
•Exceptional clarity
and coherence
Complete remote control.
The robust on-board CPU in
all StudioLive AI speakers also
makes possible an extensive
set of control features for
customizing and optimizing the
system and for monitoring and
fine-tuning performance in real
time.
Since system EQ can be set-up
per speaker independently of a
mixer, mixer output EQs are freed
up for other uses.
SL Room Control software
provides each full-range model
with wired and wireless remote
control of
•Speaker group 31-
band graphic EQ
•8-band parametric EQ
•10 notch filters
•Variable high pass filter
•Speaker delay (up to 250 ms)
•Mute and Solo
•Output level
Performance monitoring con-
stantly provides information for:
•Excursion limiting
•Over temperature
•ADC clip detection

All these DSP features are

Control for iPad, OS X, and Windows.
The CoActual approach to better
speaker design.
The new CoActual driver
uses a single magnet structure,
shared by the midrange/woofer
and compression driver. This
results in a much more compact,
lightweight assembly that keeps
the compression-driver diaphragm
located in close proximity to the
larger cone voice coil.
A purpose-built high-frequency
horn is used for high frequency
pattern control and also to keep the
HF energy o of the woofer cone.
This allows the StudioLive AI PA to
remain sonically stable at high levels.
The crossover overlaps the HF
horn and woofer, thereby allowing
the compression driver to fill in
the woofer frequency range that
is shadowed by the horn. TQ™
processing allows the compression
driver to work at lower frequencies
without sonic artifacts.
The woofer’s larger radiating
surface works in conjunction with
the HF horn to improve directional
control at the bottom of the horn’s
operating range. This increases
directional control beyond what can
be accomplished by the horn alone.
At the low-frequency end of its
range, a coaxial horn "leaks" sound
back onto the woofer cone. This
reflects forward, out of time, and
produces tonal colorations that
don’t respond to conventional EQ.
TQ™ eliminates these colorations,
thereby removing one of the primary
shortcomings of conventional co-
axial designs.

SL ROOM CONTROL SOFTWARE
Wired and wireless integration
with SL Room Control Software.
The SL312AI communicates
with SL Room Control software over
a wireless or wired LAN network
and communicate performance
parameters such as temperature,
clipping, etc.
SL Room Control is a speaker
management system and remote
control/monitoring software for
StudioLive AI-Series Loudspeakers.
It is designed for use with
Windows, OSX and iPad.
Use the included USB WiFi dongle
to connect to an established wireless
network, or hardwire your StudioLive
loudspeaker to your wireless router
using an Ethernet connection to
provide more stable connectivity.
In addition to providing remote
wireless control over all onboard
features, SL Room Control includes a
Group 31-band Graphic EQ, 8-Band
Parametric EQ, speaker delay as well
as room setup and speaker grouping.
In short, this powerful software ap-
plication opens up the power of the
onboard DSP, providing optimization
tools that were previously only avail-
able in stand-alone rack units.
Onboard Speaker Delay
Using multiple sets of speakers
in a live performance can make a
huge dierence in the quality of the
sound. Rather than relying on a pair
of front-of-house speakers to fill the
entire room, you can create listen-
ing zones throughout the room so
that your front-of-house system only
needs to be loud enough to cover the
front of the room.
This allows you to lower the level,
give the front row listeners’ ears a
break, and get better fidelity from
your speakers.
Delay systems allow you to pro-
vide the same listening experience
throughout the entire venue by
extending the reach of the FOH
system. The onboard DSP on the
StudioLive AI-series loudspeakers
allows you to achieve this experience
without any additional equipment or
wiring.
Onboard Speaker Grouping
SL Room Control provides in-
dividual and grouped speaker
management. Once you have EQ’d
and set the delay time and level for
each speaker, you can group them
together. Grouping speakers allows
you to adjust the overall GEQ of your
entire FOH or
Satellite sys-
tem; addition-
ally, you can
mute or solo
individual
speakers in
the system.
