- INPUT: Balanced inputs using 1/4" TRS and XLR connectors.
- POWER: Main power switch.
- INPUT TRIM: Adjusts input sensitivity to match the signal source.
- LOW FREQUENCY: Adapts the woofer for subwoofer systems or emulates smaller speaker characteristics.
- ROOM COMPENSATION: Adjusts the speaker response based on its setup position.
- HIGH FREQUENCY: Adapts frequency response to the damping characteristics of the control room.
- POWER MODE: Toggles between "ON", "OFF", and "AUTO" power-up modes.
- MUTE LOW / MUTE HIGH: Disables the woofer or tweeter respectively for servicing and maintenance.
Technical Specifications
The monitors differ in power and component size:
- B2031A: 140W RMS power, 8 3/4" woofer, 1" tweeter.
