DX-2B Active Crossover

Hear the World, Hear Different.

  • Frequency Response:5HZ~22KHZ(±0.5dB)
  • Total Harmonic Distortion(THD+N):-106dB(DC~22khz Measuring Bandwidth, Unweighted)
  • Signal-to-Noise Ratio(SNR):110dB
  • Dynamic Range (DNR):116dB
  • Input Impedance:10KΩ
  • Output Impedance:600Ω
  • Line Level Output:XLR:9.6Vrms
  • The Adjustable Bandwidth Range:0~-20dB 1dB Precision
  • Slope Selection:-12dB,-18dB,-24dB Every Tenfold Frequency
  • Hot-swappable and replaceable crossover cards.
  • The data is measured when used as a full-range buffer. The performance of each channel's THD+N varies significantly depending on the crossover parameters.
  • Due to the attenuation in the stopband caused by the crossover, the THD+N performance is typically better than its nominal specifications.
Input and Output Interfaces
  • Analog Audio Output: Balanced(XLR)*1 unit
  • Analog Audio Output: Balanced(XLR)*6 units
Power Supply and Power Consumption
  • Input Voltage Range: 00~240Vac/47~63Hz
  • Power Consumption: 52W
  • Standby Mode: 1W
Temperature and Humidity Requirements
  • Operating Environment Temperature: +5°C to +35°C
  • Operating Environment Humidity: 5% ‒ 85% (No condensation)
  • Storage Temperature: -20°C to +55°C


The product consists of a single unit, with various versions of appearance to choose from, including black and white aluminum alloy casings, and so on.

The entire crossover operation is carried out purely through analog circuitry, ensuring no loss of details caused by digital-analog or analog-digital conversions. DX-2B features a 20dB adjustable range with a precision of 1dB and includes 4 crossover points, allowing each channel to support adjustments for up to 5 channels. Crossover points can be easily modified by replacing different crossover cards.

DX-2B Active Crossover

Science and technology

DX-2B uses a pioneering switching power supply to achieve AC-DC conversion. It can operate within a wide voltage range of 80-280V, completely resolving the power supply challenge that audiophiles find most difficult to address.
