Port A and B digital audio networking
All iLive MixRacks provide two audio networking ports. These are Port A and Port B. Both can handle up
to 64 channels of bi-directional 24-bit audio with 48kHz sampling rate.
Port A
is typically used as the
Surface to MixRack link transporting mix position local audio to and from the MixRack, and is fixed as
ACE™ for these MixRack models. Port B is an option slot able to accept one of several cards available
from Allen & Heath. Refer to the Allen & Heath web site for more information on the options available as
more are added as new standards become established.
Control network
3 port Ethernet
switch. Connect laptops, wireless
router, link iLive networks, connect
external TCP/IP networks, or link to an
iLive Surface that does not have an
ACE™ port. Control only, no audio.
Port A
ACE™ port to link audio and control
between the MixRack and
Surface
. Network
control is internally bridged via ACE™ allowing
a single CAT5 cable to be used (separate
Network cable is not needed).
Port A is also used when connecting a Slave
MixRack to a Master in
Dual-Rack
mode to
expand the system to 128 input channels.
Note 1:
CH1-32 and 63/64 are reserved for
Surface audio sockets, headphones and
talkback. If you connect to a modular iLive
Surface then you can use ACE™ CH33-62 to
patch outputs to an MMO option card fitted to
that Surface RAB2 Port B.
Note 2:
The modular iDR10 and iDR0
MixRacks provide a RAB2 Port A option slot
instead of ACE™ so that the user can choose
which standard to use for the Surface link.
Port B option slot
Capable of 64 channel bi-
directional digital audio transmission at the iLive
sampling rate of 48kHz. Fit none or one of the option
cards available from Allen & Heath. Use for:
Digital mic splitter
to link multiple MixRacks in
FOH/Monitor/Recording/Broadcast systems,
Dual-Rack input expander
to link two MixRacks to
expand the number of inputs feeding the mix to 128.
Networking audio
between iLive systems, mix and
broadcast equipment,
Interfacing with popular industry standards
such as
EtherSound and MADI,
Multitrack recording
using various popular formats,
Sending signals to personal monitor systems
such
as Aviom™ and Hearback™,
Linking to Allen & Heath IDR products
including
iDR-8, iDR-4, and iDR output expanders.
iLive signals can be patched to Port B channels using
the
OUTPUTS
screen.
If you are linking two MixRacks, for example to digitally
split the mic inputs from one to both racks, then set
the ‘Slave’ rack to sync off the ‘Master via Port B’. Set
this using the
MIXER SETUP / Mixer Pref / Audio
Networks
screen audio clock source option.
ACE™
Adds a second ACE™ port. Use one socket
for the link. Use the second socket for a redundant
backup connection if required. Use a short cable to
bridge the NETWORK over the ACE™ cable if needed.
EtherSound
Industry standard bi-directional 64
channel network. Control port allows connection of a
laptop running an ES monitor program for advanced
routing.
MADI
Industry standard network popular with
recording devices and broadcast systems. Up to 64
channels. Allows many options to daisy chain and
split signals to multiple devices. Can work with
external 48kHz word clock.
MMO
Provides several popular digital formats – up to
24 track ADAT, 16 channel Aviom™ monitor system,
Hearbus™, 2x 8-channel digital links to Allen & Heath
iDR Series mix processors and output expanders.
