- COAXIAL Socket: Connects to a TV's COAXIAL OUT socket using a COAXIAL cable.
- OPTICAL Socket: Connects to a TV's OPTICAL OUT socket using an OPTICAL cable. Protective caps should be removed before connection.
- AUX Socket: Connects to a TV's audio output sockets or external audio device headphone socket using a 3.5mm audio cable or RCA to 3.5mm audio cable.
- Bluetooth Operation:
- Pairing: To connect a Bluetooth device, select Bluetooth mode on the soundbar (Blue indicator flashes slowly). Search for "A&S Bar 300" on the Bluetooth device and enter "0000" if a password is required. The unit will voice "Paired" and the Blue indicator will light up solidly upon successful pairing.
- Playback: Once paired, music can be streamed from the Bluetooth device. The remote control can be used for play/pause (►II/PAIR button) and track skipping (◄◄,►►I buttons).
- Disconnection: Bluetooth can be disconnected by switching to another function, disabling Bluetooth on the device, or pressing and holding the ►II/PAIR button on the unit or remote control.
- Operational Range: Approximately 8 meters without obstacles.
Wireless Subwoofer Pairing:
- Automatic Pairing: After plugging in both the soundbar and subwoofer and switching the soundbar ON, they will automatically pair within 30 seconds. The subwoofer's Pair indicator will flash during pairing and light up steadily when successful.
- Manual Pairing: If automatic pairing fails, unplug both units for 3 minutes, then plug them back in. Press and hold the PAIR switch on the subwoofer until the Pair indicator blinks rapidly, then switch the soundbar ON. The Pair indicator will become solid upon successful manual pairing.
Placement and Installation:
- Table Placement: The soundbar can be placed directly in front of the TV stand, centered with the TV screen.
