Controls and Settings

Bose 203 speakers are passive and controlled through connected amplifier or audio system.

Amplifier Controls: Volume, tone controls, equalization, crossover settings if applicable.

System Configuration: Stereo or mono operation, daisy-chaining multiple speakers, impedance matching.

Positioning: Adjust angle and height for optimal sound coverage. Use included mounting hardware for secure installation.

Connecting Devices

Connect to amplifier or audio system using appropriate cables and connectors.

1. Turn off all equipment before making connections.
2. Use proper gauge speaker wire for the distance and power requirements.
3. Connect to amplifier outputs matching speaker impedance.
4. For multiple speakers, ensure total impedance is within amplifier specifications.
5. Secure all connections to prevent shorts or disconnections.

Tip: Label wires for easy identification in multi-speaker installations.

Operation Guidelines

Proper operation ensures optimal performance and longevity.

1. Power sequence: Turn on amplifier last, turn off first to prevent pops and damage.
2. Volume management: Start at low volume and increase gradually to desired level.
3. Monitoring: Listen for distortion which indicates potential overload.
4. Environmental considerations: Protect from extreme temperatures and moisture unless specified as weather-resistant.
5. Storage: When not in use, store in dry, temperature-controlled environment.

WARNING! Do not operate at volumes causing audible distortion; this can damage speakers.

Safety Features

Built-in protection: Thermal and overload protection circuits help prevent damage from excessive power or temperature.

Mounting safety: Use only approved mounting hardware and follow weight capacity guidelines.

Electrical safety: Ensure proper grounding of all audio equipment.

Care & Cleaning

Disconnect from power before cleaning. Use soft, dry cloth for exterior surfaces.

CAUTION! Do not use liquids, solvents, or abrasive cleaners. Avoid getting moisture into ports or connectors.

Grille cleaning: Use soft brush to remove dust from speaker grille if removable.
