Installation

Unpack and inspect contents. Ensure proper lifting equipment for heavy speakers.

1. Positioning: Place on stable surface or appropriate speaker stands.
2. Flying: Use certified rigging hardware and professionals for overhead installation.
3. Connect audio: Use SpeakON cables from amplifier outputs to speaker inputs.
4. Power connection: Connect amplifier to AC power source.

WARNING! Speakers are heavy; use proper lifting techniques or equipment. Ensure rigging is performed by qualified personnel only.

First-Time Setup

Connect system components and power on in correct sequence.

1. Connect speakers: Use appropriate gauge SpeakON cables from amplifier outputs.
2. Connect sources: Connect mixer/processor outputs to amplifier inputs.
3. Power sequence: Turn on sources first, then amplifier, to prevent pops.
4. Test system: Play audio at low volume to verify all connections.
5. Adjust EQ: Use system processor or mixer EQ to optimize for venue.

CAUTION! Always power off amplifier when making connections. Match amplifier power to speaker specifications.

Connecting Audio Sources

Connect mixer/processor to amplifier, amplifier to speakers.

1. Turn off all equipment before making connections.
2. Connect mixer outputs to amplifier inputs using balanced XLR or TRS cables.
3. Connect amplifier outputs to speaker inputs using SpeakON cables.
4. For multiple speakers, use parallel connections via second SpeakON port.
5. Verify impedance load on amplifier when connecting multiple speakers.

Tip: Use high-quality, properly rated cables for professional installations.

Operation Guidelines

Proper operation ensures optimal performance and longevity.

1. Power sequence: Sources → Processor → Amplifier ON; reverse for OFF.
2. Volume: Gradually increase to operating level; avoid sudden full volume.
3. Monitoring: Listen for distortion which indicates overdriving.
4. Thermal management: Ensure adequate ventilation for amplifier.
5. Transport: Use protective covers and secure properly in vehicle.
6. Storage: Keep in dry, temperature-controlled environment.

WARNING! Do not operate with damaged cables or connectors. Discontinue use if speaker produces distorted sound or no sound.

System Configuration

For optimal performance in various applications:

Live Sound: Use as main PA speakers, typically in pairs per side. Angle for proper coverage.

Monitoring: Can be used as floor monitors when placed on side.

Installation: Permanent install using rigging points or brackets.

Processing: Use high-pass filter at 60-80Hz when used without subwoofers.

With Subwoofers: Use crossover at 80-100Hz when paired with compatible Bose subwoofers.

Care & Maintenance

Regular maintenance ensures optimal performance and longevity.

1. Cleaning: Wipe exterior with dry cloth. For stubborn dirt, use mild soap solution on cloth only.
2. Grille: Vacuum gently to remove dust from grille surface.
3. Connectors: Keep SpeakON connectors clean and free of debris.
4. Inspection: Regularly check for physical damage, especially before flying.
5. Storage: Store in dry environment, avoid extreme temperatures.

CAUTION! Do not use solvents or abrasive cleaners. Never spray liquids directly on speaker.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No sound from speaker	Connection/power issue	Check all cables; verify amplifier is on and receiving signal.
Distorted sound	Overdriven or damaged	Reduce volume; check for damaged driver; inspect amplifier clipping.
Intermittent sound	Loose connection	Check SpeakON connections; inspect cables for damage.
Low output	Impedance mismatch	Verify amplifier impedance setting; check parallel wiring.
Rattling noise	Loose component or damage	Inspect for loose hardware; check driver suspension.
Hum or buzz	Ground loop or cable issue	Check cable routing; use balanced connections; try ground lift.
