Euphonix Max Air Installation Guide
Digital I/O
All digital I/O is converted to and from MADI format via the DM714 AES/EBU to MADI
Converter, and the MD704 MADI to AES/EBU Converter. Each unit's main I/O handles
24 signals (12 AES/EBU pairs) and also contains an auxiliary stereo analog input or output,
and an auxiliary stereo digital input or output (AES/EBU and S/PDIF). All digital inputs
have built in Sample Rate Converters.
Format Conversion
The FC727 is a bidirectional device with 56 channels of sample-rate-converted I/O. All inputs
and outputs are converted to and from MADI which are connected to the MADI I/O on the
DF64 MADI card or through the optional SH612 Studio Hub. In addition to AES/EBU I/O,
the FC727 allows direct connection to several third-party digital formats. Formats sup-
ported by the unit are TDIF, ProDigi, SDIF-2, ADAT Optical, and Pro Tools. AES/EBU
outputs are always active even when using third-party formats. The FC726 is the same as
FC727 but has no support for Pro Tools.

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. Up to seven ML530s may be connected in a system.

Monitoring

The MC524 Monitor Controller provides analog monitor outputs. This unit provides Main
(7.1), Alt 1 (5.1), and Alt 2 (stereo) control room monitoring, SLS (7.1), and Cues 1–3
(each stereo) studio monitoring, two talkback preamps, and four listen microphone
preamps. The MC524 is connected to a dedicated MA703 MADI to Analog Converter.

Power

Some of the Max Air console components have dual power entry connectors for redundant
power supplies. We recommend deriving the two power supplies from different sources to
maximize the failsafe capabilities of the system. The best case is to connect one power sup-
ply to a UPS (Uninturuptable Power Supply) and the other to a clean technical power
source. If a UPS is not used, the power supplies should be connected to seperately protected
clean technical power circuits.

Digital Sync

A high quality digital sync source is required for the Max Air console. Some facilities may
already have a digital master clock or house reference in place but others may require one.
Euphonix has tested several digital sync generators and distribution amplifiers and can supply
these devices with the console. Contact a Euphonix sales representative for further information.
