Official product information provided by Fosi Audio
The following product descriptions, specifications and images are provided by the manufacturer.
Fosi Audio BT30D is a compact 2.1-channel Bluetooth integrated amplifier for two passive speakers and a passive or powered subwoofer.
Dedicated subwoofer level and crossover controls make it a straightforward way to build an adjustable small-room, desktop or TV audio system.
Why it stands out
True 2.1-channel speaker control
Separate stereo and subwoofer amplification supports passive speakers plus a passive subwoofer from one compact unit.
Passive and powered subwoofer flexibility
Speaker-level subwoofer output and a line-level subwoofer connection support different bass-system configurations.
Dedicated bass integration
Subwoofer volume and cutoff adjustment help blend low frequencies with the main speakers.
Compact analog control
Master volume, bass, treble, subwoofer level and crossover adjustment are available directly from the front panel.
Best for

EMiUZEK Buying Notes
- The main left/right outputs are for passive speakers.
- Use the dedicated speaker output for a passive subwoofer or the line-level output for a powered subwoofer.
