dB-Mark DP24 PLUS V2 - 2-in 4-out Digital Active Crossover
July 2021 Update DP PLUS V2 series allows remote control over LAN via TCP/IP with built in web-based GUI - currently this works with PC only and is not compatible with Apple based products
2 balanced inputs and 4 balanced outputs on XLRs. Outputs are impedance balanced, and not fully active balanced
DP+ Series allows remote control over LAN via TCP/IP with built-in web-based GUI
All channels can be configured using Parametric EQ, High/Low Shelf EQ, and 1st/2nd order All Pass filters.
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
