2. Setup
Follow these steps to set up your Advent AW400 Wireless Stereo Speakers:
- Unpack Components: Carefully remove all items from the packaging. You should have two speakers (one Master, one Slave), an AC adapter, and an RCA audio cable.
- Identify Speakers: Locate the Master Speaker (A) and the Slave Speaker (B). The Master Speaker typically has the main controls and input jacks.
- Connect Power: Plug the AC adapter into the Power Connection Input Jack (C) on the Master Speaker. Then, plug the AC adapter into a standard electrical outlet.
- Connect Audio Source: Use the provided RCA Cable (S) to connect your audio source (e.g., TV, MP3 player, smartphone, laptop) to the RCA Jack (E) on the Master Speaker. Ensure a secure connection.
- Position Speakers: Place the speakers in your desired listening area. The wireless signal operates at 900 MHz, offering flexibility in placement.
- Power On: Locate the ON/OFF Switch (F) on the Master Speaker and switch it to the 'ON' position.

3. Operating Instructions
Once your speakers are set up, follow these steps for optimal operation:
- Power On: Ensure the ON/OFF Switch (F) on the Master Speaker is in the 'ON' position. The power indicator light should illuminate.
- Adjust Volume: Use the volume controls on your audio source to adjust the sound level. The speakers will amplify the signal received.
- Tune Speakers: If you experience static or poor sound quality, use the Tuning Control (G) on the Master Speaker to fine-tune the wireless signal. Slowly rotate the dial until you achieve the clearest audio.
- Stereo Sound: The system is configured for 2.0 channel stereo sound. Ensure both speakers are receiving a signal for a complete audio experience.
- Compatible Devices: These speakers are compatible with a wide range of devices including laptops, MP3 players, smartphones, and tablets that have an RCA audio output or can be connected via an appropriate adapter (not included).
4. Maintenance
To ensure the longevity and performance of your Advent AW400 speakers, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the speaker surfaces. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
- Storage: When not in use for extended periods, store the speakers in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid Moisture: These speakers are not waterproof. Keep them away from water, high humidity, and other liquids to prevent damage.
- Cable Care: Handle all cables and connections with care. Avoid bending or crimping cables excessively, which can lead to internal damage.
5. Troubleshooting
If you encounter issues with your Advent AW400 speakers, refer to the following common problems and solutions:
- No Sound:
- Ensure the Master Speaker's ON/OFF Switch (F) is in the 'ON' position.
- Verify the AC adapter is securely plugged into both the speaker and a working electrical outlet.
- Check that the RCA audio cable is firmly connected to both the Master Speaker's RCA Jack (E) and your audio source.
- Confirm your audio source is powered on and playing audio, and its volume is turned up.
- Static or Poor Sound Quality:
- Adjust the Tuning Control (G) on the Master Speaker slowly until the sound becomes clear.
- Relocate the speakers or the audio source to minimize interference from other electronic devices (e.g., cordless phones, Wi-Fi routers).
- Ensure there are no large metallic objects or walls directly obstructing the line of sight between the speakers and the audio source (if applicable for wireless transmission).
- Only One Speaker Working:
- Check the connection between the Master and Slave speakers (if applicable, some models have a wired connection between them).
- Ensure the audio source is outputting a stereo signal.
