Product Features
· 32-bit DSP processing, 48kHz sampling rate, 24-bit AD/DA conversion.
· 4 balanced Line/MIC inputs and 4 balanced outputs.
· Each input channel can independently select a preamp with +48V phantom power; preamp gain is individually adjustable.
· Input channel processing includes: low-cut filter, feedback suppression, 5-band parametric EQ, noise gate, gain, mute, phase, link control, and volume group adjustment.
· Output channel processing includes: crossover, 7-band parametric EQ, gain, mute, compressor/limiter, phase, delay, link control, and volume group adjustment.
· Free matrix routing between all inputs and outputs.
· All parametric EQ frequency, gain, and bandwidth are adjustable; gain step is 0.1dB. EQ types: PEAK, H-SHELF, L-SHELF, Low Cut, High Cut.
· High-cut, low-cut filters, and crossovers can be selected as Butterworth, Linkwitz-Riley, or Bessel types, with slopes from -6dB/Oct to -24dB/Oct (10 options).
· Input channel noise gate parameters (threshold, attack, release, hold time) are continuously adjustable. Output channel compressor/limiter parameters (threshold, ratio, attack, release) are continuously adjustable.
· All input and output parameters can be linked; input and output channel names are editable.
· Delay modules support up to 680ms delay with 0.021ms steps.
· Parameters can be freely copied between channels; built-in test signal generator included.
· Each panel channel has signal and clipping indicators; device also includes power and network status indicators, with password protection.
· 21 user presets and 1 factory preset; entire device or individual preset files can be saved and recalled separately. Supports Chinese and English PC software with one-click network connection for convenient operation.
· Control via USB port or remote Ethernet connection; supports timed control and cascading up to 250 devices.
