combine high power and advanced coaxial configuration with
the most powerful DSP engine ever
built into a compact PA system.
Through seamlessly integrated software, StudioLive AI speakers can be
set up, adjusted and continuously
monitored via wired or wireless remote control using Windows®, OS X®
or iPad®. An optional card provides
Dante networking.
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 reflections,
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

• Exceptional clarity and coherence
Complete remote control.
The robust onboard 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 for Mac
OS X, Windows, and iPad provides
each full-range speaker and groups
of speakers with wired and wireless
remote control of a variety of features.
Remote Control over:
• DSP contours

Performance monitoring over:
• Excursion limiting
• Real-time temperature
• ADC clip detection

Optional Dante networking.
The SL-Dante-SPK upgrade option
card houses one Ethercon connection for Dante™ audio networking
and remote control via SL Room
Control. It oers two Dante Transmit
and two Receive channels and operates at 48 kHz.
Dante-enabled StudioLive AI-
series loudspeakers allow users to
create a complete, networked audio
system with any Dante-enabled mixer using a standard 1 GB Ethernet
switch and Audinate’s Dante digitalmedia networking technology, which
oers self-configuring, true plug-
and-play digital audio networking.
Users can also connect non-Dante
mixers, such as a first-generation
StudioLive, to the analog inputs of a
Dante-equipped AI loudspeaker and
then broadcast the signal over the
Dante network using CAT5 cables.
This makes Dante-enabled StudioLive AI an ideal solution for large
front-of-house systems.
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 voicecoil.
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
SL312AI
3-way PA
Loudspeaker
®
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 coaxial designs. The result is extremely
accurate transient reproduction,
making the speaker less subject to
intermodulation distortion.
