Aviom C4m 4-Channel Mic/Line Input Card

The Aviom C4m Mic/Line Input Card provides four remote-controllable mic/line-level inputs for modular AllFrame systems. Each preamp offers the pristine archival-quality audio that Aviom systems are known for. Essential channels strip controls—gain, phantom power, low-cut filter, and phase are individually controllable.

Up to six C4m cards can be installed in a single F6, the host frame for the modular AllFrame system, putting up to 24 remote-controlled mic preamps in a single location. Mix and match I/O cards to create custom Pro64 devices configured for your specific needs.

The C4m card’s four remote-controllable analog mic- or line-level inputs feature the same mic preamp circuitry found in the state-of-the-art 6416m Mic Input Module and provide clean, transparent A-to-D conversion without compromise. Once digitized, the signals can be routed anywhere in the Pro64 network and output in a variety of formats including analog line-level, mic level, AES3 digital and/or directly into a Yamaha console with a 6416Y2 A-Net Card installed.

The preamp channel strip settings on the C4m inputs can be remote-controlled from an MCS Mic Control Surface, select Yamaha digital consoles by using the Pro64 network’s m-control feature, or from the Pro64 Network Manager software.

The modular nature of the I/O cards in an AllFrame system allows the user to reconfigure the network’s I/O devices to suit the needs of the application in just minutes. Imagine trying to do that with traditional analog cabling.

Features:

• Clean, transparent, archival-quality audio
• Four XLR female inputs per card
• Remote controllable from RCI/MCS, Yamaha consoles, or Pro64 Network Manager
