• Fully adjustable crossover filters on all output channels, with slopes from 12dB to 48dB per octave.
• Linkwitz-Riley, Butterworth, or Bessel curves can be individually selected on the high-pass and low-pass.
• Each input has 2 dynamic EQs, noise gate, and adjustable compressor.
• Automatic Gain Control available on input channels.
• Configurable compressor and peak limiter on every output channel.
• Delay on all channels, adjustable in milliseconds, metres or feet.
• Full matrix mixing, route any input to any output.
• All input and output channels can be individually muted.
• Channels can be linked for convenience to allow editing of two or more channels at a time
• 32-bit digital signal processor with 24-bit 96KHz A/D and D/A converters.
• USB 2.0/3.0, RS485*, and Ethernet connections are provided for PC control of multiple devices.
