1.2 Overview of the System Components
1.2.1 DF64 Digital Audio Frame
The DF64 Digital Frame performs all System 5-B audio processing: dynamics, EQ, bus-
ses (mix, record, aux, and monitor). System 5-B uses one Mixer Model (one DF64 with
a SH612 Studio Hub), which has the following characteristics: 96 channels, 24 groups/
clean feeds, 16 aux sends, 24 Mix sections and 24 external inputs).
1.2.2 Analog and Digital I/O
The engineer has complete freedom to decide how to route sources and destinations to
the console, which easily handles 448 digital and analog sources.
Digital and analog I/O units connect all devices via MADI. All audio signals are con-
verted to and from the MADI format through analog and digital converters. The System
5-B includes eight MADI Inputs and six MADI Outputs. Each 75-Ω coaxial MADI ca-
ble can carry up to 56 channels of 24-bit digital audio at 44.1 or 48 kHz. These MADI
inputs and outputs appear at the console’s internal router/patchbay. See Console I/O on
page 55 for more information.
Microphone Inputs
Microphone inputs are handled by the ML530 Mic/Line Interfaces. Each unit contains
24 remote-controlled microphone preamps. Each ML530 is connected to a dedicated
AM713 Analog to MADI Converter. A single system can include up to seven ML530s.
Monitoring
The MC524 Monitor Controller provides the following analog monitor outputs:
• Control Room Monitoring: Main (7.1), Alt 1 (5.1), and Alt 2 (stereo)
• Studio Monitoring: SLS (7.1), and Cues 1–3 (each stereo)
• Two talkback preamps and four listen microphone preamps
The MC524 is connected to a dedicated MA703 MADI to Analog Converter.
