Ideal for flown indoor installations
Designed specifically for indoor flown installations, these models are available in white (328i-W) and black (328i-B) and have internal grille cloth that masks the drives so they blend seamlessly with their environment. Pole mounts and handles have been removed to facilitate flown installations. The front-panel blue power LED can be turned off in SL Room Control software.
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
Less fatiguing listening experience at very high SPLs
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.

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 offers 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 Dante-enabled mixer using a standard 1 GB Ethernet switch and Audinate's Dante digital media networking technology, which offers 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 loudspeakers 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 voice coil. A purpose-built, high-frequency horn is used for high frequency pattern control and also to keep the HF energy off of the woofer cone. This allows StudioLive AI PA loudspeakers 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 coaxial designs. The result is extremely accurate transient reproduction, making the speaker less subject to intermodulation distortion.
SL Room Control Software
Wired and wireless integration with SL Room Control software
The StudioLive 328i communicates with SL Room Control software over a wireless or wired LAN network and provides a wealth of system control and performance-monitoring features. SL Room Control is a speaker management system and remote control/monitoring software for StudioLive AI-series loudspeakers that runs under Windows, Mac OS X and iOS for iPad. Use the included USB Wi-Fi dongle to connect to an established wireless network or hardwire your StudioLive loudspeaker to a 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 speaker group management and individual speaker control including eight notch filters, eight-band parametric EQ, output delay and performance monitoring. It also enables you to turn the front-panel blue power-status LED off. In short, this full-featured software opens up the power of the onboard DSP, providing optimization tools that were previously only available in standalone rack units.
Onboard speaker delay
Using multiple sets of speakers in a live performance can make a huge difference 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 listening 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 provide 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 individual and grouped speaker management. Grouping speakers allows you to adjust the overall graphic EQ of your entire FOH or satellite system. In addition, you can mute or solo individual speakers in the system and quickly zoom in on different groups around the venue.
