SRI Card
Overview
Expand your VENUE system with additional analog inputs. The SRI (Stage Rack Input) Card is an option for the VENUE 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 VENUE 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)
