Modular I/O

Modular I/O configurations consist of one or more 3RU double-sided frames that can be
fitted with a variety of I/O modules. For interface to the console, all signals are converted
to MADI. Depending on the configuration, a maximum signal density of 64 inputs and 64
outputs can be achieved on a single MADI I/O. Audio formats supported are remote-con-
trolled preamp, line level analog, AES/EBU, and HD/SD embedder/de-embedder. These
formats can be used simultaeously in the same frame. Refer to the Euphonix Modular
Configuration Guide for more details and configuration possibilities.

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.
We recommend following these guidelines:
•
It is important to minimize the timing differences between signal paths to avoid
cumulative timing errors. It is good system engineering practice to send sync
signals to all system components from one source.
•
Sync signals should not be looped and each distribution amplifier should be fed
directly from the master clock source.
•
Drawings in this installation guide show the use of Word Clock. The user may
use either AES/EBU sync (DARS) or Word Clock.
