Latency / monitoringESI calls the EWDM driver low-latency and provides ASIO 2.0, WDM, DirectSound and MME paths; no fixed buffer/round-trip figure is stated on the product page.
Driver / OS compatibilityEWDM drivers. ESI lists Windows Vista/7/8/8.1/10/11 (32/64-bit) and Mac OS X compatibility; check current downloadable package and host support before installation.

Compatibility & preservation

Do not assume the separately labeled mic, Hi-Z, line, headphone and S/PDIF paths share the same gain or channel mapping. Phantom power applies to the microphone input; check levels before connecting equipment.

  • Photograph the card label, PCB revision, rear connectors and included breakout cables before service.
  • Retain the exact working driver, firmware, operating-system version, clock and routing configuration.
  • Confirm lane wiring, bracket clearance, channel map and external converter/network compatibility; connector fit alone is not a compatibility guarantee.
