he StudioLive 18sAI is the
powered 18" subwoofer in
T
the StudioLive AI-series loudspeaker line. It is designed to compliment full-range StudioLive AI-series
speakers while being flexible enough
to work with other powered loudspeakers.
Interestingly, it incorporates more
digital signal processing than any
competitive full-range speaker on
the market. This allows it to function as the final component of a true
4-way system when used with StudioLive AI full-range models.
The StudioLive 18sAI utilizes the
same 2x500-watt bridged power
amplifier distribution that powers
the low-frequency woofer in the StudioLive 312AI, 328AI, and 315AI. It
also features stereo inputs that, with
analog pass-thru, can be summed
mono.
The 18sAI features two DSP contours optimized for live performance
and enhanced low end. It also oers
three delay presets: 0m for use with
a full-range speaker atop the sub;
1m for use with a full-range speaker
on a separate speaker stand; and 2m
for use with a full-range speaker on
stage.
An optional card provides Dante
networking.

with 24-bit/96 kHz DSP

Advanced 24-bit floating-point
digital signal processing.
Like the StudioLive AI-Series
full-range models, the SL18sAI was
tuned by master speaker designer
Dave Gunness using Fulcrum Acoustic’s proprietary algorithms.
This results in a truly "smart" subwoofer capable of DSP contol of :
• True 4-way integration with full-
range StudioLive AI models
• DSP-monitored temperature,
over-voltage, and
excursion limiting
• Multiple onboard delay setting
to optimize the 18sAI with three
common subwoofer positions
• Two DSP contours
Complete remote control.
The robust onboard CPU in the
StudioLive 18sAI makes possible
an extensive set of control features
for customizing and optimizing the
system and for monitoring and finetuning performance in real time.
SL Room Control software for Mac
OS X, Windows, and iPad provides
the StudioLive 18sAl with wired and
wireless remote control of a variety
of features.
Remote Control over:
• DSP contours
Network setup wizard
• Network scanning automatically
detects connected speakers
• Network browser

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 AIseries loudspeakers allow users
to create a complete, networked
audio system with any Danteenabled mixer using a standard 1
GB Ethernet switch and Audinate’s

Dante digital-media networking
technology, which oers selfconfiguring, 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.
