ALLFRAME

Multi-Modular I/O System

™

The C4m Mic/Line Input Card is an audio input card for the
AllFrame Multi-Modular I/O System. The C4m can be installed

in any frame, such as the six-slot F6 Modular I/O Frame.

Both network and audio settings for the C4m inputs can
be configured using the Pro64 Network Manager™ control
application. Audio settings can also be controlled remotely

from the MCS Mic Control Surface and compatible Yamaha

digital consoles.

C4m BLOCK DIAGRAM

Each channel on the C4m can accept a mic- or line-level
input and features gain control in 1dB increments, phase
invert, 85Hz low cut filter, and +48V phantom power.
Channel strip parameters can be controlled from the Pro64
Network Manager software, from the RCI/MCS hardware
controller, or via m-control™ from Yamaha® consoles. The
audio circuitry of the C4m mirrors that of the Pro64 6416m
Mic Input Module and provides clear, transparent audio
performance.
