3. Safety Information
WARNING: To prevent fire or shock hazard, do not expose this equipment to rain or moisture.
CAUTION: To prevent electrical shock, do not remove cover. No user-serviceable parts inside. Refer servicing to qualified service personnel.
Always ensure proper ventilation and avoid blocking any ventilation openings. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat. Use only attachments/accessories specified by the manufacturer.
4. Setup and Installation
The OWI AMP602W is a surface mount speaker. Ensure the mounting surface is sturdy enough to support the speaker's weight (approximately 12 lbs).
4.1 Mounting
- Select a suitable location for mounting the speaker.
- Securely attach the provided mounting bracket to the desired surface using appropriate hardware (not included, depending on surface type).
- Attach the speaker to the mounting bracket, ensuring it is firmly in place.
4.2 Connections
Refer to the image below for a visual guide to the rear panel connections and controls.

The rear panel of the OWI AMP602W speaker features several controls and connection points:
- VOLUME Control: Adjusts the overall output level of the speaker.
- HIGH Control: Adjusts the high-frequency response.
- LOW Control: Adjusts the low-frequency response.
- INPUT (RCA): Connect your audio source (e.g., mixer, media player) to these RCA input jacks. The 'L' input is typically for the left channel, and 'R' for the right channel, though this speaker operates in mono.
- OUTPUT (Speaker Terminal): This terminal allows you to connect an additional passive speaker (4 Ohms, 25 Watts maximum) to expand your audio system. Ensure correct polarity (+ to + and - to -).
- POWER Switch: Toggles the speaker's power ON or OFF.
- AC Power Inlet: Connect the provided 115V power cord here.
4.2.1 Audio Input
Connect your audio source to the RCA INPUT jacks on the rear panel. Use appropriate RCA cables for a secure connection.
4.2.2 Power Connection
Connect the provided 115V power cord to the AC Power Inlet on the rear panel. Plug the other end into a standard 115V AC power outlet. Ensure the power switch is in the OFF position before connecting to power.
4.2.3 Speaker Output (Optional)
If connecting an additional passive speaker, use speaker wire to connect it to the OUTPUT terminal. Observe correct polarity: connect the positive (+) terminal of the AMP602W to the positive (+) terminal of the passive speaker, and the negative (-) terminal to the negative (-) terminal. The passive speaker should be 4 Ohms and rated for at least 25 Watts.
5. Operating Instructions
- Power On: After all connections are made, flip the POWER switch to the ON position. The power indicator light should illuminate.
- Adjust Volume: Start with the VOLUME control set to a low level. Begin playing audio from your source and slowly increase the VOLUME to the desired listening level.
- Adjust Tone: Use the HIGH and LOW controls to fine-tune the treble and bass frequencies to suit your preference and room acoustics.
- Power Off: When finished, turn the VOLUME control down, then flip the POWER switch to the OFF position.
6. Maintenance
To ensure the longevity and optimal performance of your OWI AMP602W speaker, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the speaker's exterior. Do not use liquid cleaners or aerosols, as they may damage the finish or internal components.
- Ventilation: Ensure that the speaker's ventilation openings are not obstructed to prevent overheating.
- Environment: Avoid exposing the speaker to extreme temperatures, high humidity, or direct sunlight.
- Power Cord: Regularly inspect the power cord for any signs of damage. If damaged, replace it immediately with an approved cord.
7. Troubleshooting
If you encounter issues with your OWI AMP602W speaker, refer to the following troubleshooting steps:
- No Power:
- Check if the power cord is securely plugged into both the speaker and a working electrical outlet.
- Ensure the POWER switch on the rear panel is in the ON position.
- Verify the electrical outlet is functional by plugging in another device.
- No Sound:
- Confirm the audio source is playing and its volume is turned up.
- Check that the audio input cables are correctly connected to the RCA INPUT jacks on the speaker and the audio source.
- Ensure the VOLUME control on the speaker is turned up.
- If using the speaker output for a passive speaker, check its connections and ensure it is functional.
- Distorted Sound:
- Reduce the VOLUME level on both the speaker and the audio source.
- Check the audio input cables for damage or loose connections.
- Adjust the HIGH and LOW tone controls to see if the distortion improves.
If the problem persists after attempting these steps, contact OWI customer support or a qualified service technician.
