XTA Audio Processor
Excellent sound quality: high-precision 96KHz/24bit data processing, achieving an excellent 116dB dynamic range and high-quality sound quality.
Each output channel is equipped with independent high-performance limiters, and the start and release times can be automatically or manually set.
Each output has a variable high pass and low-pass filter. Its filtering slope can be 6, 12, 18, 24 or 48dB Octave band. The frequency division filtering curve can be of Bessel, Butterworth, Linkowitz or Rayleigh response types. The separately controlled high pass and low-pass filtering functions can use uneven frequency division.
Each output channel is equipped with a delay setting of up to 650ms, with an adjustment accuracy of 2.6 μ s. (Equivalent to distance, less than 1 millimeter).
Equipped with AES/EBU digital input/output interface for digital system connection
The DP4 series uses a switching power supply, which can automatically adapt to 60-250V 50/60Hz voltage
