Product Introduction:
Dual 15 Digital Equalization
  • features



    DGP-215 is a dual-band graph parameter equalizer with 15 filters per frequency band.

    Used in stereo or independent bands, its filters are designed to be symmetrical, with high pass and low

    Pass filter. This product is easy to operate, it has a central rotary decoder that can be easily

    Operate on the 2 x 20 alphanumeric LCD function menu. DGP-215 has 32 recoverable memories, 16 of which are pre-set in the factory,

    16 are available for use by the user. DGP-215 allows users to quickly build, assemble, and store

    Save the newly set parameters. The relevant parameters can be managed and stored with numbers or names. Can also pass

    The MIDI, RS232, and USB interfaces are externally controlled for bidirectional information. Processor----------------------- Digital Equalizer
