Issue 2
Part number M-MADI-A
M-MADI is one of several plug-in card options that may be fitted to
the iLive Series. It provides a multi channel digital audio network
that can distribute signals between iLive and 3
rd
party MADI
equipment. MADI offers an addition or alternative to EtherSound
and other networking standards available for the iLive system.
MADI (Multichannel Audio Digital Interface) is an industry
standard multiple channel audio interface documented by the Audio
Engineering Society as AES10. The M-MADI option supports 64
channels of 48kHz serial digital audio transmission over 75 ohm
coaxial cable to a maximum cable length of up to 150 meters (500
feet) depending on equipment connected and cable type used.
Two MADI ports are provided. These are referred to as LINK 1 and
LINK 2. Each has two BNC connectors, one for audio input, the
other for audio output. To connect audio in both directions two
cables must be used. iLive sources may be assigned from either
input port in blocks of 8. Outputs patched to MADI appear at both
port outputs. LINK 2 may be used as a second MADI port or
configured for redundant cable connection. One redundant cable is
required for each direction connected. The audio within the MADI
card can be synchronised to either LINK 1 or LINK 2 or to the word
clock. The iLive can be synchronised to this audio by setting its
sync to Remote Port B.
Lnk/Act Yellow indicator flashes steadily to indicate that the
network is linked and active. It lights solid if the port is connected to
a second cable available as a redundant link.
Error Red indicator lights when a connection or data error is
detected. It is normal for it to light briefly when the cable is plugged
or unplugged.
AUX An additional BNC connection can be configured in one of
four different ways – to mirror
OUT socket, to duplicate audio from the LINK 1 IN socket so
passing it thru
or clock output
to other equipment, or to use it as a word clock input
.

The M-MADI card option may be fitted to Port B in the MixRack.
First make sure the MixRack is switched off. Remove the 2 screws
securing the blank panel over Port B. Slide the M-MADI card into
the slot and press it firmly into the mating connector. Secure the
card in place using the 2 screws.
Fitting to iDR10 and iLive Surfaces
ALLEN&HEATH
The option card can be fitted into the Port A (MixRack or Surface) or
Port B (MixRack only) slot in the Remote Audio 2 (RAB2) module.
Systems fitted with the older Remote Audio module can be
upgraded with the new RAB2 module.
Note The option port is not available on T Series surfaces.
Note Up to and including firmware version V1.6 the M-MADI card
may not be fitted in the Surface Port B. The only option currently
supported in Surface Port B is the M-MMO (Mini Multi Out) card.
First make sure the System is switched off. Remove the 2 screws

Operating modes
Dual Link mode The card supports two separate MADI BNC
links letting you connect to two separate devices simultaneously.
Make sure the MIXER SETUP / Mixer Pref screen Redundant Link
Option is set to ‘Off’.
Sources
to the iLive channels can be patched from either LINK 1 or
LINK 2 MADI stream in blocks of 8. First, use the MIXER SETUP /
Mixer Pref screen to set up which MADI link is made available as a
selectable source to the blocks of 8 iLive channels. Next, select
MADI as the source to individual or a range of channels using their
PREAMP screens or the MIXER SETUP / Mixer Pref / Quick
Source Setup screen.
Outputs
to the MADI links are patched using the OUTPUTS screen.
Select the source from the drop down menu. The same outputs are
broadcast on both MADI LINK 1 and LINK 2.
Redundant mode Set the MIXER SETUP / Mixer Pref screen
Redundant Link Option to ‘On’. This configures LINK 1 and LINK 2
as a redundant pair. Audio and clock will continue without
interruption if one of the cables fails or is unplugged.

Cables Two 75 ohm coaxial cables with BNC connectors are
required for each link, one for each direction of audio. The MADI
standard supports up to 50 meters (165 feet). However, the M-
MADI card features an equalizing receiver circuit, originally
designed for HD video, allowing greatly increased sensitivity and
noise rejection. Because of this, connecting two A&H MADI cards
together allows cable runs in excess of 150m (3 times the standard)
depending on cable type. All inputs, including word clock, are ACcoupled, to avoid potential ground loop problems.
