| dB-Mark DP48 4-in 8-out Digital Active Crossover
Features
- 96K Hz sampling frequency, 32-bit DSP processor, 24- bit A/D and D/A converter.
- 4 inputs / 8 outputs
- USB and RS485 connectors. Up to 250 digital speaker managers can be connected together via RS485 and controlled remotely up to 1500 meters away.
- Convenient use of function buttons on either front panel or the included software interface displays.
- 30 user-program parameters can be stored into the device.
- Parameters can be safely locked against unauthorized users or unwanted changes.
- 6 independent parametric EQ for the input/output. The gain range rises from -20 to 20 dB per band. The output channel EQ can be adjusted to act as a Lo-shelf or Hi-shelf.
- 4 2%uFFFD2 LCD blue back-light display present. 6 level meter LED display (mute and edit status of input/output displayed too).
- Compensation-delay, phase-control and mute settings for each input/output channel. It offers a maximum length of 1000ms of delay that can be displayed in milliseconds, meters and feet all together.
- Adjustable gain and limiter of output channel; Several input/output signals can be adjusted with the same parameters by the link available option.
