SRI Card


Expand your D-Show or Profile System with additional analog inputs. The SRI (Stage Rack Input) Card is an option for the Stage Rack that provides eight channels of software-controlled, fully recallable analog mic/line inputs through XLR connectors.

You can install up to six SRI Cards into a single Stage Rack for a total of 48 analog mic/line input channels, or mix and match with other Stage Rack option cards to customize your input.

Key Features

  • Eight channels of analog mic/line-level inputs through XLR3-female connectors
  • 24-bit sigma-delta analog-to-digital (A/D) converters
  • 20 dB pad (selectable per channel using VENUE software)
  • 48V phantom power (selectable per channel in VENUE software)
  • Signal presence and phantom power LEDs
  • Polarity invert (selectable per channel using VENUE software)
