Installation

Unpack and inspect contents. Plan array configuration based on coverage needs.

Determine mounting location: Ensure structure can support weight of array.
Prepare rigging hardware: Use appropriate bolts, clamps, and safety cables.
Connect array modules: Align and secure units using integrated rigging points.
Route cables: Connect Speakon or barrier strip cables between units.
Secure to structure: Double-check all fasteners and safety connections.

WARNING! Installation at height requires certified personnel and proper safety equipment. Always use safety cables.

First-Time Setup

After installation, configure system for optimal performance.

Connect to amplifier: Use appropriate gauge speaker cable to power amplifier.
Set amplifier gain: Start with low gain and increase gradually during testing.
Test each module: Verify all units in array are functioning properly.
Adjust array angle: Tilt array as needed to cover listening area.
Perform system tuning: Use equalization to optimize for the environment.

CAUTION! Never exceed maximum power rating. Allow adequate ventilation around amplifiers.

Controls and Settings

MA12 is a passive speaker with no onboard controls. System control via external processors/amplifiers.

Amplifier Settings: Set appropriate gain structure. Processor Settings: Use Bose Controller or DSP for equalization, limiting, crossover. Array Configuration: Adjust vertical splay between modules (typically 0° or 7.5°).

System tuning should be performed by qualified audio professional using measurement tools.

Connecting Devices

Connect to amplifier using Speakon cables or barrier strip connections.

Turn off all system power before making connections.
Use appropriate gauge speaker cable for the run length and power.
Connect amplifier output to first MA12 module input.
Link subsequent modules using loop-through connectors.
Verify polarity is consistent throughout array.

Tip: Label all cables at both ends for easy identification during troubleshooting.

System Configuration

MA12 modules can be configured in various array patterns.

Determine coverage needs: Calculate required vertical coverage angle.
Select array length: More modules provide narrower vertical coverage.
Set splay angles: Adjust angle between modules to shape coverage pattern.
Consider subwoofers: Add Bose subwoofers for full-range systems.
System processing: Use Bose controllers for optimized performance.
Time alignment: Align array with other system components if needed.
Zone configuration: Multiple arrays can cover different areas.
Monitor system: Use system monitoring tools if available.

WARNING! Do not exceed maximum array length recommended by Bose. Follow all rigging guidelines.

Safety Features

Integrated rigging points with safety lock. Weather-resistant design for outdoor use. Thermal protection in recommended amplifiers.

Care & Maintenance

Regular inspection of rigging hardware and connections. Clean with damp cloth only; no harsh chemicals.

CAUTION! Schedule professional inspection of rigging annually or as required by local regulations.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No sound from module	Connection/power	Check amplifier power and connections; verify cable continuity.
Distorted sound	Overdriven/ damaged	Reduce amplifier gain; check for damaged components.
Intermittent sound	Loose connection	Inspect and secure all cable connections at both ends.
Uneven coverage	Array configuration	Verify array angles and aiming; consider adding modules.
Rattling noise	Loose hardware	Check all rigging and enclosure hardware for tightness.

Reset: Check amplifier and processor settings.
