2.1 Step 1: Install SL Room Control
2 Networking Your Loudspeaker
Your StudioLive AI-series loudspeaker can connect directly to a wireless
router using an Ethernet cable, or it can connect to the router wirelessly using
the USB Wi-Fi adapter that is included in the box with your loudspeaker. It
is important to mention that the StudioLive loudspeaker does not support
hot-swapping the Wi-Fi adapter; the adapter must be connected when
you power on your loudspeaker. Note that the included adapter is the
only LAN adapter supported for use with StudioLive AI loudspeakers.
Power User Tip: The use of more than one instance of SL Room
Control on the speaker network is not supported.
2.1 Step 1: Install SL Room Control
2.1.1 Mac OS X
Installing SL Room Control on Mac OS X machines is a simple as drag-and-drop.
1. Double-click on the SL Room Control .dmg file.
2. Drag the SL Room Control icon to the Applications folder on your computer.
SL Room Control
User Guide
3. Once SL Room Control has been copied to your hard drive, it is ready
to use. Simply double-click on its icon in your Applications folder.
2.1.2 Windows
The Windows installer for SL Room Control provides easy-to-follow onscreen
instructions to make the installation process quick and simple.
1. When you launch the SL Room Control .exe file, a Welcome screen will launch. By
default, SL Room Control will install in the Program Files folder on your computer.
We highly recommend that you do not change this default location. Click “Install.”
2. Once SL Room Control has been successfully installed on
your computer, click “Finish” to exit the install wizard.
2.1.3 iPad
SL Room Control for Apple iPad is available free from Apple’s
App Store and must be downloaded from there.
2.2 Step 2: Update Your Loudspeaker Firmware
To use SL Room Control, you must update the firmware for your
StudioLive AI loudspeaker. The firmware is available from your
My PreSonus account at https://my.presonus.com.
1. Log into your My PreSonus account.
2. Download the firmware-update file for your loudspeaker.
3. Open your Downloads folder and locate the StudioLive firmware folder. The
folder will be named with your StudioLive AI loudspeaker model name.
4. Depending on your system preferences, the firmware folder may not
automatically uncompress from the .zip file. To expand it, simply double-click it.
5. Open the firmware folder; you will find a file inside named “upgrade.bin.”
6. Connect a FAT32-formatted USB thumb drive to your computer.
Power User Tip: Most small USB drives (16 GB or less) are already
formatted correctly, so no formatting is required. If your loudspeaker does
not detect your thumb drive, verify that it is formatted correctly.

2.3 Step 3: Connecting your Network
7. Select the upgrade.bin firmware file and copy/paste or drag it to the root level of
your thumb drive. Eject your thumb drive and disconnect it from your computer.
IMPORTANT: Always label the thumbdrive with the StudioLive AI loudspeaker model
firmware loaded on it. Loading the wrong model firmware on your loudspeaker will
result in poor performance and may require a recovery to reload the correct firmware.
If you are unsure of the model firmware you have copied to your drive, it is highly
recommended that you verify by overwriting the file with the confirmed correct firmware
before proceeding. In other words: only load the firmware file for a 315AI on a 315AI.
8. Power off your StudioLive AI loudspeaker.
9. Remove the Wi-Fi LAN adapter from your loudspeaker (if connected).
10. Connect the USB thumb drive to the USB port on your StudioLive AI loudspeaker.
11. Hold down any button on the back of your StudioLive AI loudspeaker while
powering it on. Continue holding the button for 10 full seconds before releasing it.
12. The lights on the back panel of your StudioLive loudspeaker will cycle until
the firmware update is complete. The firmware update takes approximately
60 seconds. When the update is complete, your loudspeaker will reboot.
Note: You must update the firmware on every loudspeaker with which you intend
to use SL Room Control. Each StudioLive AI loudspeaker model has its own firmware
upgrade file. Do not use the firmware update for one model on another model!

2.3 Step 3: Connecting your Network
Connecting via Ethernet
If you are hardwiring your loudspeakers to your wireless router with Ethernet cables,
simply connect the speakers to your wireless router and then wirelessly join the
same network with your computer or iPad. No other network setup is required.
Power User Tip: In the event that you require more ports than your wireless router
provides, you will need to purchase an Ethernet switch and connect it to your router
to provide the additional ports. PreSonus recommends using an unmanaged
switch, rather than a managed switch, as this type requires no additional setup or
configuration. Whenever hardwiring your computer, it is recommended that it be
connected to a port on an Ethernet switch rather than using the local ports on a
router as some routers require additional set-up to support this configuration.

4.3 Speaker Mapping
4.3 Speaker Mapping
A map is created after any loudspeaker is added to a speaker group. Each
loudspeaker’s settings are stored in its position in the speaker group map.
Any changes to a loudspeaker’s settings are also stored in this map.
If a loudspeaker is not detected on the network, its mapped
position is still saved with the group. In this way, you can use a
different loudspeaker to fill this position in the map.
SL Room Control
User Guide
Simply open the Speaker Net browser and drag it the map position you want it to
use. All the stored settings will be loaded into the new loudspeaker automatically.
Speaker mapping can also be useful when loudspeakers are accidentally placed
in a different position in the room than their stored location in the speaker group.
For example, if you’ve set up your FOH system so that the 312AI that was on the
left when you created the speaker group is now on the right, SL Room Control
can easily resolve this: Simply drag the left-side 312AI’s icon over the right-side
312AI’s icon. This will exchange the settings between the two loudspeakers.

4.4.1 Performance Monitoring
Each loudspeaker icon features several performance-monitoring indicators:
• Input Metering. This meter displays the level of the incoming signal to your
loudspeaker.
• Clip. This indicator will illuminate red when the signal going to the analog-to-
digital converter (ADC) on the loudspeaker exceeds 0 dB. At this level, the signal
will begin to overload the converter and exhibit signs of clipping, an undesirable
type of distortion. Use the physical input level controls on the back of your
StudioLive AI loudspeakers and the outputs of your mixer to keep the signal
below 0 dBFS.
• Limit. This indicator will illuminate yellow when your loudspeaker’s protection
limiter has been engaged. All StudioLive AI-series loudspeakers provide reliable
operation at high sound-pressure levels by incorporating an innovative new
multiband-limiting architecture. This system evaluates both the excursion and
voice-coil temperature of every driver and uses that information to maximize the
output of the loudspeaker, while preserving the integrity of audio sources that
span more than one band. This means that even when exceeding the threshold of
the limiter, StudioLive AI-series loudspeakers continue to provide clean and
powerful sound, without the harsh edginess that is characteristic of conventional
protection schemes. Because of this, you may need to use the Limit indicator to
verify that your loudspeakers are not being driven into the danger zone.

• Thermal. This indicator monitors the temperature of the onboard amplifiers. It
will not illuminate while the temperature is within normal operating limits (less
than 147˚ F/63.9° C). It will illuminate yellow when the temperature rises to
dangerous level (147 – 152˚ F/63.9 – 66.7° C). It will illuminate red when the
temperature rises to a level where your loudspeaker will be severely damaged
(over 153˚ F/67.2° C). Note: If this indicator turns yellow or red, power off your
loudspeaker immediately and let it cool down. Your loudspeaker should not exceed
thermal limits during normal operation. If it does, you may need to contact PreSonus
to arrange for a repair.
• Excursion Limit. The movements of the low- and mid-frequency drivers are
monitored to make sure an over-excursion will not occur, as this can significantly
damage your loudspeaker. If any of the drivers in the loudspeaker icon illuminate
red, the excursion limiter has been engaged to protect the speaker. This indicates
that you are driving your loudspeaker too hard and should lower the volume.

Speaker Edit Enable. Enables/Disables speaker editing.
By default, Speaker Edit is enabled. Click or tap the button to disable
speaker editing; this will bypass all parameters, and you will no longer have
remote control over the speaker. In this way, you can monitor performance
without risking making any changes to a speaker or A/B your changes.

Click or tap the Mute button to mute the currently selected loudspeaker.
You will be alerted when a loudspeaker is muted wherever
its icon is visible in SL Room Control.
Solo. Solos the loudspeaker.
Click or tap the Solo button to mute every other speaker in the group.
Temperature. Displays the current temperature of the amplifiers.
Temperature monitoring for your loudspeaker is available in realtime from the Speaker Edit page. This is especially useful when
using your loudspeakers in elevated temperatures.
Note: Your loudspeaker should remain below 147˚ F (63.9° C). If it exceeds
this temperature, power off your loudspeaker immediately.
HPF (full-range only). Remotely enables/disables the highpass filter.
When enabled, this button engages a highpass filter that removes
frequency content below 100 Hz. (This low-frequency content may
introduce destructive cancellation and reinforcement when combined
with the highest frequencies reproduced by a subwoofer.) The filter may
also be used to remove stand thumps, mic-handling noise, etc.
Power User Tip: In addition to the highpass filter, phase- and time-alignment settings
are applied. These settings are optimized for use with the StudioLive 18sAI; however
you can use this mode with any subwoofer. Because these are fundamental tuning
parameters, your loudspeaker will mute momentarily while they are applied.
18
Page 21
4 Speaker Groups
4.6 Speaker Edit Page
Polarity (18sAI only). Remotely enables/disables polarity reverse.
When enabled, the Polarity button reverses the polarity of the summed input signal.
Power User Tip: Reversing the polarity can improve the system’s response when lowfrequency waveforms from the subwoofer are reinforced or cancelled by waveforms from
another subwoofer or from the low-frequency drivers of the full-range loudspeakers. This
is a complex interaction that also includes room acoustics, so setting it is best done by ear.
Mode. Remotely changes the DSP Contour mode.
Your StudioLive AI-series loudspeaker is equipped with different DSP contours.
These contours change the character of your StudioLive loudspeaker
in a fundamental way, adjusting FIR filters, alignment, and crossover
settings to customize your loudspeaker for different applications.
Because these contours are changing fundamental tuning parameters,
your StudioLive AI-series loudspeaker will mute momentarily
while the new parameters load. Because of this, do not change
the DSP contour once your performance has begun.
Volume. Controls the input level of your loudspeaker’s DSP.
The Volume control consists of five elements:
Power User Tip: By setting both the line input and speaker output
level controls on the back panel of your loudspeaker to 0 dB (that is, no
attenuation), you can limit the maximum level the speaker can achieve. This
is especially useful in situations where multiple people have access to the
loudspeaker system, and SPL constraints are imposed on the venue.
Alignment Delay. Controls the output delay for your loudspeaker. You can delay
your loudspeaker up to 500 ms in 0.1 ms increments.
The Alignment Delay control consists of five elements:
SL Room Control
User Guide
• Normal. Normal mode sets dynamics and equalization for optimum performance
for live sound reinforcement. This mode is suitable for most live applications.
• LBR Source (full-range only). StudioLive AI-series loudspeakers are designed to
provide high-resolution, accurate reproduction of high-quality recordings and
live mixes. When low-bit-rate MP3s are played, the unusual clarity of AI speakers
may reveal the artifacts of MP3 compression to an unflattering degree. The LBR
Source contour is specifically designed to reduce the audibility of these artifacts.
• Floor Monitor (full-range only). Floor Monitor mode sets dynamics and
equalization for optimum results when the loudspeaker is used as a floor monitor.
• Extended LF (18sAI only). Inserts a subharmonic bass
synthesizer to extend extreme deep bass response.
• On/Off switch. By default, level control is off. To
enable it, click or tap the On/Off switch.
• Level readout. This displays the input level for the onboard
DSP. You can also manually enter the level in decibels you
wish to set by clicking or tapping in this field.
• Fader. This controls the level of your loudspeaker.
• 0.2 dB increment/decrement buttons. Use these buttons
to make fine adjustments to your loudspeaker level.
• On/Off switch. By default, alignment delay is off. To
enable it click or tap the On/Off switch.
• Time readout. This displays the delay time in milliseconds. You can also manually
enter the time in milliseconds you wish to set by clicking or tapping in this field.
• Fader. This controls the alignment-delay time for your loudspeaker
in whole milliseconds. Note: Do not make drastic changes to the
alignment delay time while passing audio through your loudspeaker.
• 0.1 ms increment/decrement buttons. Use these buttons to make fine
adjustments to your loudspeaker’s delay time.

4.6 Speaker Edit Page
Power User Tip: The alignment delay compensates for the cancellation or
reinforcement of low frequencies when the same frequencies are reproduced by two
sound sources that are set apart from one another, such as a center-fill speaker that
is reproducing the summed stereo signal in a front-of-house system. By using fine
output-delay adjustments on the center-fill speaker and carefully setting the level,
the entire system can be put in phase, creating a seamless transition so that the
audience can’t hear where either main speaker ends and the center-fill begins.
Limiter threshold. Controls the limiter threshold for your loudspeaker. Note: This is
not your loudspeaker’s protection limiter.
The Limiter control consists of five elements:
SL Room Control
User Guide
• On/Off switch. By default, the limiter is off. To
enable it click or tap the On/Off switch.
• Threshold readout. This displays the set limiter threshold. You can also manually
enter the threshold in decibels you wish to set by clicking or tapping in this field.
• Fader. This controls the threshold of the limiter. When the signal’s
amplitude (level) exceeds the threshold setting, the limiter will
engage. The threshold can be set from -28 to 0 dB.
• 0.5 dB increment/decrement buttons. Use these buttons to make fine

Cannot switch networks
SL Room Control only supports global provisioning; that is, every speaker detected
by SL Room Control’s network wizard must be capable of connecting a network in
order for that network to be available. If your desired network is not selectable within
the network list, make sure that all your StudioLive AI-series loudspeakers are within
range and that their USB Wi-Fi LAN adapters are connected and functioning properly.
If you are connecting some speakers wirelessly and others are hardwired to the same
network, temporarily disconnect the speakers you wish to hardwire while you are
provisioning the speakers that will use USB Wi-Fi adapters to connect to the network.

Cannot make changes to an EQ or notch filter
In order to make changes to an EQ or notch filter, it must first
be enabled. Make sure the On button is active.
Cannot hear changes being made to a speaker
If you are making changes on the Speaker Edit page, but cannot hear the changes
being applied, make sure the speaker’s Edit Enable button is engaged.
Speaker is not visible in the Speaker Net Browser
Once a speaker has been added to a group, you will not see it in the Speaker Net
Browser. Make sure it has not been added to any group in the current Venue preset. If
it is not in the Speaker Net Browser or in any group, click or tap the Rescan button in
the Speaker Net Browser. If it still is unavailable, verify that it is powered on and that
its Ethernet cable or USB Wi-Fi LAN adapter is connected and functioning properly. If
connecting wirelessly, verify that the speaker is within range of your wireless router.
Lost fidelity or performance after firmware update
Each StudioLive AI-series model requires its own firmware. Verify that
you have downloaded the correct firmware for your model and reload
it. In other words, do not apply a 315AI firmware update to a 312AI.
Speakers are not visible wirelessly after joining new network
If your speakers are not available wirelessly after programming the new
network name and password, reconnect the Ethernet cable to your wireless
router and confirm that you have entered the correct password.
No speakers are visible on the network
If you are hardwiring your computer to your StudioLive AI loudspeaker network,
you may need to connect it to a switch, rather than a port on your router. Not
all routers support this configuration by default. To avoid complicated network
configurations, it is recommended that hardwired computers be connected
to a standard Ethernet switch instead. Please note that this relates only to
hardwired computers running SL Room Control. StudioLive AI loudspeakers
can be hardwired either to the router or the switch. All network configurations
(hardwired or wireless) require that a router be connected. Direct connection
from an OS X or Windows computer is not supported without a router.

Added bonus: PreSonus’ previously Top Secret recipe for…
Chicken and Andouille Gumbo
Ingredients:
• 1 C All-Purpose flour
• ¾ C Vegetable Oil
• 1 large onion (diced)
• 1 small onion (quartered)
• 6 celery stalks (diced)
• 1 large green bell pepper (diced)
• 3 cloves garlic (2 minced, 1 whole)
• 1 lb link Andouille sausage
• 4 Chicken leg quarters
• 4 qt water
• 4 bay leaves
• 1 tsp thyme
• 1 tsp Old Bay seasoning
• 1-2 C frozen okra, sliced
• ¼ C fresh parsley, minced
• 6-8 eggs (optional)
Cooking Instructions:
1. In a large pot, combine whole chicken leg quarters, water, quartered onion, Old Bay, 2 bay leaves and 1 whole clove garlic.
Cover and bring to a low boil. Simmer stock until chicken is falling off the bone. Remove the chicken and set aside. Discard
the onion, bay leaves, and garlic, reserving the liquid.
2. In a heavy saucepan, heat 1 Tbsp of the oil on medium high heat and brown the andouille until it is cooked through. Set
aside sausage for later.
3. In the same saucepan, add and heat remaining oil. Slowly add flour 1-2 Tbsp at a time, stirring continuously. Continue
cooking and stirring the roux until it is a dark brown (it should look like melted dark chocolate). Be careful to not to get the
oil too hot or the flour will burn and you’ll have to start over.
4. Once roux has reached the correct color, add diced onion, celery, green pepper, and minced garlic. Cook until vegetables
are very tender. Do not cover.
5. Slowly add 1 quart of chicken broth and bring to a low boil, stirring constantly.
6. Transfer roux mixture to a soup pot and bring to low boil. Do not cover, the roux will settle on the bottom of the pot and burn.
7. Add remaining chicken broth, bay leaves, and thyme. Simmer for 30 minutes.
8. While gumbo is simmering, debone and shred chicken and slice the andouille.
9. Add chicken and andouille to gumbo and return to a simmer. Simmer for 30-45 minutes.
10. Stir in frozen okra and parsley and bring to a rolling boil.
11. Optional: Crack one egg into a teacup and quickly pour into the boiling gumbo. Repeat with the other eggs being careful
not to cluster them too closely. After all the eggs have risen back to the surface, reduce heat and simmer.
12. Correct seasoning with salt and pepper (red, white and/or black) if necessary.
13. Serve over rice with potato salad.
