Opstel instruksies
1. Luidsprekers koppel
The A300 supports both stereo and BTL (Bridge-Tied Load) modes for speaker connection.
- Stereomodus: Connect your left speaker to the "LEFT +" and "LEFT -" terminals (13) and your right speaker to the "RIGHT +" and "RIGHT -" terminals (12). Ensure correct polarity.
- BTL Mode (Bridged Mono): For higher power output to a single speaker, connect the speaker to the "RIGHT +" (12) and "RIGHT -" (9) terminals. Refer to the diagram below for visual guidance.

2. Verbind oudiobronne
The A300 offers multiple input options:
- Analog Inputs (LINE IN 1 & 2): Connect your analog audio sources (e.g., CD player, DAC) to the RCA input jacks labeled "LINE IN 1" (8) or "LINE IN 2" (7).
- USB-invoer: Connect a computer or other USB audio source to the USB port (10).
- Bluetooth-invoer: Screw the provided Bluetooth antenna onto the antenna connector (11). The unit will automatically enter Bluetooth pairing mode when Bluetooth input is selected.
3. Connecting a Subwoofer (2.1 System)
To create a 2.1 audio system, connect an active subwoofer to the "SW" output (15). The A300 has a built-in high-pass filter circuit that can filter out the subwoofer frequencies, allowing the main speakers to focus on higher frequencies.
