Assembling the System

Before connecting the system to a power source, assemble the system using the array extension and mid-high array.

1. Insert the array extension into the subwoofer power stand.
2.  Insert the mid-high array into the array extension.
3. The L1 Pro8/Pro16 can be assembled without using the array extension; the mid-high array can be connected directly to the subwoofer power stand. This configuration is most useful when on an elevated stage to be sure the mid-high array is at ear level.

System Setup

Connecting Power

1. Plug the power cord into the Power Input on the L1 Pro.

2. Plug the other end of the power cord into a live electrical outlet.
   Note: Do not power on the system until after you’ve connected your sources. See Connecting Sources below.

3. Press the Standby Button. The LED will illuminate white while the system is on.
   Note: Press and hold the Standby Button for 10 seconds to reset the system to factory settings.
   AutoOff/Low-power Standby
   After four hours of no use, the L1 Pro will enter
   AutoOff/Low-power Standby mode to save power.
   To wake the system from AutoOff/Low-power
   Standby mode, press the Standby Button.
   Note: Disable AutoOff/Low-power Standby mode by pressing and holding all three Channel Parameter Controls for 10 seconds, or via the Settings page in the L1 Mix app. Enable AutoOff/Low-power Standby mode by repeating this step. Disabling AutoOff/Low-power Standby mode will result in higher energy usage when the L1 Pro is not in use.

Connecting Sources

Channel 1 & 2 Controls
Channel 1 and 2 are for use with microphones, guitars, keyboards, or other instruments. The channel inputs are suitable for a wide range of input types and will have the proper gain staging to minimize noise when the channel volume is set for the desired output level.

1. Connect your sound source to the Channel Input with the appropriate cable.

2. Apply a ToneMatch preset—to optimize the sound of your microphone or instrument—by pressing the Channel ToneMatch Button until the LED for your chosen preset is illuminated.
   Use MIC for microphones and use INST for acoustic guitars and other instruments. Use OFF if you do not want to apply a preset.
   Note: Use the L1 Mix app to choose custom presets from the ToneMatch library. The corresponding LED will illuminate green when a custom preset is selected.

3. Press the Channel Parameter Control to choose a parameter to modify. The parameter name will illuminate white while it is selected.

4. Rotate the Channel Parameter Control to adjust the level of the selected parameter. The parameter LED will indicate the level of the selected parameter.
   Note: While Reverb is selected, press and hold the control for two seconds to mute the reverb. While reverb is muted, Reverb will flash white. To unmute reverb, press and hold for two seconds while Reverb is selected. Reverb mute will reset when the system is powered off.

Channel 3 Controls
Channel 3 is for use with Bluetooth® enabled devices and line-level audio inputs.

Bluetooth Pairing
The following steps describe how to manually connect a Bluetooth enabled device to stream audio.
You can use the L1 Mix app to access additional device control. For more information on the L1 Mix app, see L1 Mix App Control below.

1. Turn on the Bluetooth feature on your mobile device.
2. Press and hold the Bluetooth Pair Button for two seconds. When ready to pair, the LED will flash blue.
3. Your L1 Pro will be visible in your device list on your mobile device. Select your L1 Pro from the device list.
   When the device pairs successfully, the LED will illuminate solid white.

Note: Some notifications may be audible through the system while in use. To prevent this, disable notifications on your connected device. Enable airplane mode to prevent call/message notifications from interrupting audio.

TRS Line Input
A mono input. Use a 6.4-millimeter (1/4-inch) TRS cable to connect line-level audio sources, such as mixers or instrument effects.

Aux Line Input
A stereo input. Use a 3.5-millimeter (1/8-inch) TRS cable to connect a line- level audio source, such as mobile devices or laptops.

L1 Mix App Control
Download the Bose L1 Mix app for additional device control and audio streaming. Once downloaded, follow the instructions in the app to connect your L1 Pro. For specific information on how to use the L1 Mix App, see the in-app help.
