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.

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.

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.

Connecting Sources

Channel 1 and 2 are for use with microphones, guitars, keyboards, or other instruments. Channel 1 and 2 will automatically detect a source input level to adjust the volume taper and gain stage.

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 system is powered off.

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

Troubleshooting

Problem	What to do
No power	•         Make sure you have power at the AC outlet. Try operating a lamp or other equipment from the same AC outlet or test the outlet using an AC outlet tester.
No sound	•         Make sure your L1 Pro is turned on.   •         Make sure your instrument is plugged into the Channel Input. •         Make sure the volume is turned up on your source. •         Make sure the volume is turned up on the L1 Pro. •         Make sure the L1 Pro isn’t in AutoOff/Low-power Standby mode. •         Plug your instrument into a different amplifier to make sure the source is working. •         Make sure the Channel Mute button is not engaged.
Standby LED is flashing red (thermal fault)	•         Turn off the L1 Pro and wait 30 minutes before turning it back on.   •         Move the L1 Pro to a cooler location. •         Move the L1 Pro to a location that has more ventilation.
Standby LED is solid red (system fault)	•         Please call Product and Technical Support at (877) 335-2673.
With nothing plugged into the L1 Pro, a light hum or buzz is heard	•         Using an AC outlet tester, test the AC outlet the L1 Pro is plugged into for reversed or open (hot, neutral, and/or ground) contacts.   •         If using an extension cord, plug the L1 Pro directly into the outlet.
Instrument or audio source sounds distorted	•         Turn down volume on the source.   •         Turn down channel volume. •         Try a different source or instrument.
Microphone is encountering feedback	•         Turn down channel volume.   •         Orient the microphone so that it is not pointing directly at the L1 Pro. •         Try a different microphone. •         Try a different position for the L1 Pro and/or vocalist on stage. •         Increase the distance from the L1 Pro to the microphone. •         If using a vocal effects processor, make sure it is not contributing to the feedback problem.

Problem	What to do
