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 cL1 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 on page 9.
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 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. Channel 1 and 2 will automatically detect when a source is close to clipping and will reduce the analog gain to avoid clipping.

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 the reverb is muted, Reverb will flash white. To unmute the reverb, press and hold for two seconds while Reverb is selected. Reverb mute will reset when the L1 Pro is powered off.
