Microlab B51 USB Power Speaker: Overview
The Microlab B51 (model B51) is a compact 2.0 USB powered computer speaker with 4 W RMS output, a 3.5 mm stereo input and an 80 Hz - 18 kHz frequency response. It is a simple, reliable choice for office desks, students and home users who want clear everyday sound from a PC or laptop.
Microlab is a familiar audio brand in computer shops, and the B51 keeps things simple: one USB plug for power and one 3.5 mm plug for audio.
Key Features
- 2.0 stereo channels: two speakers for left and right stereo sound.
- 4 W RMS output: steady, clean volume for desk-side listening. RMS is a continuous power rating rather than a short peak figure.
- USB powered: no separate power adapter; powered from a USB port or USB charger.
- 3.5 mm stereo input: connects to the audio output of PCs, laptops and other devices with a headphone jack.
- 80 Hz - 18 kHz frequency response: covers voice and most music clearly.
Best For
- Office desktops for videos, training material and online meetings.
- Students watching lectures and tutorials.
- Bank, shop and reception counters that need basic PC audio.
- Small study tables where space is tight.
Setup and Usage Tips
- Plug the USB connector into a computer port or a 5 V USB adapter for power.
- Plug the 3.5 mm audio cable into your computer's green audio-out or headphone jack.
- Place the speakers either side of your screen for proper stereo separation.
- If there is a hiss or hum, try a different USB port or a different power source.
- For deeper bass in movies and music, consider a 2.1 system with a subwoofer instead.
