2. Important Safety Information

4. Setup and Installation
4.1 Choosing a Location
Select a location that provides optimal sound dispersion and is suitable for the speaker's intended use. Consider areas such as patios, courtyards, garages, or indoor rooms. Ensure the mounting surface is sturdy enough to support the weight of the speakers.

4.2 Mounting the Speakers
- Mark Drill Holes: Hold the wall mount bracket against the desired mounting surface and mark the positions for the drill holes.
- Drill Holes: Drill pilot holes at the marked positions. Use appropriate drill bits for your wall material (wood, brick, drywall). Insert wall anchors if necessary.
- Attach Bracket: Secure the wall mount bracket to the surface using the provided screws.
- Attach Speaker: Slide the speaker onto the bracket. The design allows for easy attachment and removal without additional screws between the speaker and bracket.
- Adjust Angle: The bracket allows for 170-degree rotation both horizontally and vertically. Adjust the speaker to the desired angle for optimal sound projection.

4.3 Wiring Connections
These speakers are passive and require an amplifier for operation. Speaker wire is not included and must be purchased separately.
- Prepare Speaker Wire: Strip approximately 1/2 inch (1.2 cm) of insulation from the ends of your speaker wire. Twist the bare strands tightly.
- Connect to Speakers: Press down on the terminal clips on the back of each speaker. Insert the positive (+) wire (usually red or marked) into the red terminal and the negative (-) wire (usually black or unmarked) into the black terminal. Release the clips to secure the wires.
- Connect to Amplifier: Connect the other ends of the speaker wires to the corresponding positive (+) and negative (-) speaker output terminals on your amplifier. Ensure correct polarity for both speakers and the amplifier.
5. Operating Instructions
Once the speakers are securely mounted and correctly wired to an amplifier, you can begin operation:
- Power On Amplifier: Turn on your amplifier.
- Select Source: Choose the audio source on your amplifier (e.g., Bluetooth, AUX, CD).
- Adjust Volume: Start with the amplifier volume at a low level and gradually increase it to a comfortable listening level.
- Sound Optimization: Adjust the speaker angles as needed to optimize sound direction and coverage for your listening area.
6. Maintenance and Care
To ensure the longevity and optimal performance of your Saiyin speakers, follow these maintenance guidelines:
- Cleaning: Wipe the speaker enclosures with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish and waterproof properties.
- Terminal Inspection: Periodically check the speaker terminals for any signs of corrosion, especially in marine or high-humidity environments. The rust-free terminals are designed to resist corrosion, but regular inspection is recommended.
- Mounting Security: Regularly inspect the wall mount brackets and mounting hardware to ensure they remain secure. Tighten any loose screws if necessary.
- Environmental Protection: While the speakers are waterproof, extreme weather conditions (e.g., prolonged heavy rain, direct saltwater spray) can still impact performance over time. Consider additional protection or temporary relocation if severe conditions are expected.
