CIML4 – Mic/Line Analog Input Card
The CIML4 card provides four channels of switchable microphone and/or line-level analog audio input with 48 V phantom power as well as high-quality preamplification and A/D conversion. This card provides inputs for microphones, mixers and CD/DVD players.
For configuration information, see Mic/Line In (I/O Card). For documents and other information, see the I/O Cards product page.
About Type 2 Hardware
The CIML4 card is Type 2 hardware.
Type 2 hardware provides new cables and connectors between the I/O cards and main boards in Cores and I/O Frames. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label on the back of the Core and I/O Frame, and the bottom of the I/O cards.
