D/ESAM 230
Digital Mixer


D/ESAM-230

Graham-Patten’s most cost-effective digital mixer offers powerful performance in a sleek and compact design that integrates a control console and electronics chassis in a single table-top unit. Like the high-end mixer models, the D/ESAM 230 offers programmable device assignments, industry standard ESAM II and D/ESAM IV protocols, simultaneous support for both analog and digital inputs, programmable audio delay, multi-band parametric EQ, full monitoring and metering, and four digital and analog output buses. Features now standard on the D/ESAM 230 that were once available only on the high-end D/ESAMs include send outputs, monitor sub-mixer, fader range, user configuration registers, and D/MEM write protection.

Features include:

  • Analog and digital input architecture
  • Familiar user interface
  • Editor interface
  • Expandable architecture
  • D/MEM register storage & recall
