Unpacking and Setup

Unpack all components and inspect for damage. Assemble on a stable, level surface.

1. Assemble the Stand: Attach the L1 Compact Array to the top of the Power Stand base, ensuring it locks securely.
2. Position the System: Place the assembled unit on a flat surface. Ensure it is stable and not at risk of tipping.
3. Connect Power: Plug the included power cable into the AC input on the Power Stand base and then into a wall outlet.

WARNING! The array is top-heavy when assembled. Always ensure the base is stable and use caution when moving the assembled system.

First-Time Power On

Power on the system and configure initial settings.

1. Power On: Press the POWER switch on the rear of the Power Stand. The status LED should illuminate.
2. Set Channel Levels: Begin with all channel volume knobs and the master volume at the minimum (fully counter-clockwise).
3. Connect a Source: Plug a microphone or instrument into Channel 1 or 2.
4. Adjust Volume: Slowly increase the corresponding channel volume, then adjust the master volume to a comfortable listening level.
5. Test All Inputs: Repeat for each input channel you plan to use.

CAUTION! Avoid turning on the system with volume controls set high to prevent loud pops or feedback.

Operating the Mixer

Use the top panel controls to mix your audio sources.

1. Set Individual Levels: Adjust each channel's VOLUME knob to balance the sources relative to each other.
2. Apply Tone Shaping: Use the BASS, MID, and TREBLE knobs on each channel to tailor the sound (e.g., reduce bass on a vocal mic, boost treble on an acoustic guitar).
3. Control Overall Volume: Use the MASTER VOLUME knob to set the final output level for the room.
4. Muting: To mute a channel, turn its VOLUME knob fully down. Some models may have a dedicated mute via remote.

WARNING! Avoid driving the system into distortion (clipping). If the sound becomes harsh or the status LED flashes red, reduce the master or channel volume.

Tonal Adjustments

Recommended starting points for tone controls.

• Vocals (Channel 1/2): Start with BASS at 12 o'clock, MID slightly boosted (1-2 o'clock), TREBLE at 12 o'clock. Adjust to reduce boominess or increase clarity.
• Acoustic Guitar (Channel 1/2): Start flat (all knobs at 12 o'clock). Slight TREBLE boost can add sparkle; slight BASS cut can reduce muddiness.
• Backing Tracks (Channel 3): Often best left flat. Adjust MASTER tone if the overall system sounds too bright or dark in the room.

Care & Maintenance

Unplug from power before cleaning. Wipe exterior with a dry, soft cloth. Do not use liquids or chemical cleaners on the array or base.

CAUTION! Do not expose the system to rain or moisture. Store in a cool, dry place. The speaker array fabric should not be washed or sprayed.
