PreSonus MicroStation BT 2.1 Monitor Controller

The PreSonus MicroStation BT is a specialized desktop monitor controller designed for home studios and multimedia setups. Its primary purpose is to add Bluetooth connectivity and 2.1 subwoofer management to speakers that don’t natively support them.

Core Functionality

• The “Bluetooth Bridge”: It acts as a receiver, allowing you to stream reference tracks from your phone or tablet directly to your professional wired studio monitors.

• 2.1 System Management: It makes adding a subwoofer to a standard stereo pair effortless, providing dedicated outputs and controls for the sub.

• Tactile Volume Control: A large, ergonomic knob on top gives you physical control over your entire system’s volume (Main speakers + Sub), which is much faster than using a mouse.

Features & Controls

• Sub Bypass Button: A standout feature that allows you to instantly mute the subwoofer. This is vital for “checking your mix” to see how it sounds without the extra low-end.

• Bluetooth On/Off & Pairing: Dedicated buttons to toggle between your wired computer input and your wireless Bluetooth source.

• Main Mute: A quick-access button to silence the entire system without stopping the music on your device.

• Power: Powered via USB-C. It can be plugged into your computer or a standard 5V wall adapter (though it doesn’t transmit audio via USB).

Connections (I/O)

The back panel is surprisingly versatile for its size:

• Inputs: * 2 x Balanced $1/4″$ TRS (for your audio interface/mixer).

  • 1 x $1/8″$ Stereo Aux (for non-Bluetooth devices like a laptop or MP3 player).

• Outputs:

  • 2 x Balanced $1/4″$ TRS Main Outputs (to your studio monitors).

  • 1 x Balanced $1/4″$ TRS Subwoofer Out.

  • 1 x Unbalanced RCA Subwoofer Out.

  • 1 x $1/8″$ Headphone/Aux Out (for private listening).

Technical Highlights

• Frequency response covers 20 Hz–20 kHz (with extended range on Bluetooth).

• High dynamic range (e.g., ~108 dB on main inputs) and low distortion figures indicate clean signal handling.

• USB-C power device, so no large external PSU is needed — just a USB power source.

• Compact desktop footprint (~125 × 100 × 56 mm, ~0.45 kg).
