Loudspeaker Digital System Controller: DP2140

System Controller: DP2140 – Logic Systems Pro Audio

Loudspeaker Digital System

The Logic Systems DP2140 loudspeaker management digital system controller represents the current state-of-the-art. Taking advantages of the latest advances in analogue to digital conversion and digital signal processing technologies the units achieve performance levels that have only recently been made possible.

To assist the integration of speakers into systems, Logic Systems offers a choice of two digital system controllers. Housed in a 1 unit chassis the DP2140 offers a fully assignable two input four output format, while the DP2160 offers two inputs and six outputs. Both controllers have the option of a network card, and the PodWare software enables computer control of both DSP settings and network control. Preset files are available for all Logic Systems products and custom files can quickly be generated to tailor the control to specific venues or projects.

Key Features:

  • 2 in 4 out format with assignable input to output routing.
  • Input PEQ, HPF and delay.
  • Output PEQ, HPF, LPF, delay, polarity and limiting.
  • Linea Research minimal signal path design.
  • Sonically superb ADC/DAC combination; a carefully matched pairing of the best devices from Burr Brown and Wolfson.
  • Newly released family of Analogue Devices SHARP DSP.
  • Extended bandwidth; 96kHz sampling frequency provides for a nominally flat response to 40kHz.
  • Parameter knob and LCD provide a rapid, user-friendly control interface.
  • Networking capability to control multiples units via the Bv Net protocol.
  • Remote control of all functions via the ‘Podware’ software package.
