  • ● 96kHz/192kHz sampling rate switching, 32-bit 400MHz DSP processor, 24-bit AD/DA conversion.
    ● Each input channel is equipped with 6 levels of automatic feedback suppression.
    The input processing section includes three DEQs, twelve PEQs, FIR filters, noise gates, gain, muting, phase, delay, and other processing functions.
    The output processing section includes FIR and IIR crossover filters, 16-parameter equalizers, gain controls, muting, compressors, peak limiters, phase adjustment, delay, and linked adjustment processing units.
    ● Optional digital input and output functions are available, featuring AES/EBU input and output channels with XLR connector interfaces.
    ● The gain, bandwidth, and frequency of the PEQ for all channels are continuously adjustable, with selectable types: parametric equalization, low-shelf filtering, high-shelf filtering, low-cut filtering, high-cut filtering, 1st-order phase shifting, and 2nd-order phase shifting.
    ● The gain, bandwidth, frequency, and type of DEQ for all input channels are continuously adjustable, while the threshold, ratio, attack time, and release time of dynamic processing are also continuously adjustable.
    ● All input and output channels feature independent phase curve adjustment functions. When selecting the PEQ type as "Phase Shift 1st Order," it provides a 180-degree curve adjustment, while "Phase Shift 2nd Order" offers a 360-degree curve adjustment.
    ● The type of IIR frequency filter can be selected: Butterworth, Chebyshev, or Bessel, with slopes ranging from -6dB/Oct to -48dB/Oct.
    ● FIR Crossover Filter: The sampling point count can be selected between 256 and 512, with multiple types available and a continuously adjustable cutoff frequency ranging from 20 to 20KHz.
    ● The input channel noise gate threshold, attack time, release time, and hold time are continuously adjustable, with the noise gate ratio being independently adjustable.
    The compressor threshold, soft knee, ratio, attack time, and release time of the output channel are continuously adjustable. Additionally, the output features an independent peak limiter with continuously adjustable threshold, attack time, and release time.
    ● All input and output channel delay modules feature a delay time of up to 1200ms.
    The front panel features a 2-inch LCD full-color display, an external WiFi interface, and USB ports. The rear panel includes an RS485 interface, enabling connection to third-party central control systems with a maximum of 250 devices.
    ● 30 user presets, each of which can be individually stored and recalled. Machine parameters can be uploaded and downloaded. The ID setting function supports cascading control of up to 255 machines. The panel also features a password protection function to enhance device security.
