Assembling the Power Stand and Array

Before connecting the power stand to a power source, assemble the L1 Pro32 using the upper mid-high array and lower mid-high array.

1. Insert the lower array into the power stand.
2. Insert the upper array into the lower array.
   The L1 Pro32 can be used without the upper array. This configuration is useful when a venue ceiling cannot accommodate the height of the L1 Pro32.

Connecting Power and a Sub1/Sub2

1. Plug the SubMatch cable into the SubMatch Input on a Sub1/Sub2.
2. Plug the other end of the SubMatch cable into the SubMatch Output of the L1 Pro32.
3. Plug the power cord into the Power Input on the L1 Pro32.
4. Plug the other end of the power cord into a live electrical outlet.
   Note: Do not power on the L1 Pro until after you've connected your sources. See Connecting Sources
5. Press the Standby Button. The LED will illuminate white while the L1 Pro is on.
   Note: Press and hold the Standby Button for 10 seconds to reset the L1 Pro to factory settings.
   Press the Standby Button on any connected Sub1/Sub2. For additional information on how to set up a Sub1/ Sub2, see the Sub1/Sub2 owner's guide at PRO.BOSE.COM.
   Note: When two Subs are connected to the L1 Pro32, first turn on the Sub connected directly to the L1 Pro32, then turn on the second Sub.

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 L1 Pro from AutoOff/Low-power Standby mode, press the Standby Button. When the L1 Pro32 goes into AutoOff/Low-power Standby mode, this will cut power to any Sub1/Sub2 connected with a SubMatch cable. Press the Standby Button on a connected Sub1/Sub2 to wake it from AutoOff/Low-power Standby mode.
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 Bose Music 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 qw 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 Bose Music 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 L1 Pro is powered off.
   

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

1. Turn on the Bluetooth feature on your mobile device.
2. Press and hold the Bluetooth Pair Buttonfor 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 L1 Pro 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.

Setup Scenarios
The L1 Pro32 can be placed on the floor or on an elevated stage (see Assembling the Power Stand and Array).

Do not place the equipment in an unstable location. The equipment could become unstable leading to a hazardous condition, which could result in injury.


The power stand should not be placed anywhere that may block the ventilation holes at the rear/bottom of the L1 Pro32. Operating directly on sand or grass could cause debris to enter the product through vent openings and result in the L1 Pro32 not functioning properly.

All of the following setup scenarios require at least one Sub1 or Sub2 bass module. For proper Sub1/Sub2 settings, see the Sub1/Sub2 owner's guide at PRO.BOSE.COM.

Musician (with Sub)

Musician with Mobile Device (with Sub)

Band (with Sub)

Musician with T8S Mixer (with Sub)
Note: T8S left channel audio is delivered only.

Musician (with Analog Sub Connection)

Musician Stereo with T4S Mixer (with Two Subs)
