Product Features
· 32-bit DSP processing with 96kHz sampling rate and 24-bit AD/DA conversion.
· Supports +48V phantom power; microphone and line inputs with gain switching, microphone sensitivity adjustable.
· Input channel processing includes: high-cut and low-cut filters, parametric EQ, independent feedback suppression, noise gate, gain, mute, phase adjustment, link control, and volume group adjustment.
· Output channel processing includes: crossover, parametric EQ, gain, mute, compressor/limiter, phase, delay, link control, and volume group adjustment.
· All PEQ gain, bandwidth, and frequency are continuously adjustable; types selectable: parametric EQ, low shelf, high shelf, low-cut filter, high-cut filter, 1st-order phase shift, 2nd-order phase shift.
· Free matrix routing between all inputs and outputs; input/output channel names are editable.
· Independent phase curve adjustment for all input/output channels; 1st-order phase shift provides 180° curve adjustment, 2nd-order phase shift provides 360° curve adjustment.
· High-cut, low-cut filters and crossovers selectable as Butterworth, Linkwitz-Riley, or Bessel types with selectable slopes.
· Input channel noise gate parameters (threshold, attack time, release time) are continuously adjustable; output channel compressor/limiter parameters (threshold, ratio, attack, release) are continuously adjustable.
· Output channel delay modules support up to 680ms delay.
· Parameters can be freely copied between any channels, with optional linked adjustment.
· PEQ curve adjustment graphs for all input or output channels can be viewed from any single input or output channel.
· Built-in AEC (Acoustic Echo Cancellation) for echo elimination; includes automatic mixing, automatic gain control, automatic feedback suppression, and noise reduction to handle network delay acoustic echoes in remote video conferencing.
· Dedicated AUX channel design: can mix all microphone channels; features professional dual-engine ECHO and REVERB effects to enhance tone or fully support karaoke; suitable for conferences, multi-purpose halls, and other applications.
· AUX channel supports powerful automatic mixing with continuously adjustable parameters: threshold, amplitude, attack time, release time; also supports automatic camera tracking trigger with adjustable threshold, amplitude, attack, and release time; independent PEQ, compressor, and volume adjustments.
· Built-in test signal generator; output selectable as pink noise, white noise, or adjustable 20Hz–20kHz sine wave; signal level adjustable.
· Panel includes USB control port; rear panel with RS232 & RS485 control ports and Ethernet for remote control; one-click network connection for easy and fast operation.
· 21 user presets; device status and each preset can be stored and recalled individually. ID setting allows cascading control of up to 255 units; password protection enhances device security.
