Daisy chains and signal embedding
A perfect companion
CONNECTING TWO OR MORE DEVICES
MADI STREAM
CHANNELS
The signal that leads to your chain of devices can be used to send remote control and clock
information to them. Also, the audio that is received at each OctaMic XTC can be routed to
the available outputs of the devices below, which are 2 ADAT ports, 4 stereo AES3 outs, two
headphone outs and a 24 channel USB class compliant output - on each device.
9-16
17-24
25-32
33-40
41-48
49-56
57-64
Many MADI devices, such as the OctaMic XTC, have one
MADI input and one MADI output. But this does not mean
that each device has to have its own connection to the
computer interface. In fact, MADI devices pass through
any audio channels that they receive - except for the ones
that they insert themselves.
If you require, for example, 24 microphone inputs, all
you need to do is create a daisy-chain of three devices:
the first writes into channel 1-8 and passes this signal to
the second. The second device passes channel 1-8 directly
to the output but additionally embeds its own signal into
channel 9-16. The third device passes on channel 1-16
and embeds its own signals into channel 17-24.
The 3 sample offset between each pair of devices can be
automatically compensated with delay compensation.
USB 2.0
MADI OPTICAL
MADI COAXIAL
It doesn’t matter if the USB port is connected to a simple
USB charger or battery pack and the MADIface used in
stand-alone mode, or if it is connected to a computer
which can additionally record all 64 microphone signals
that are received from the attached set of preamps.
When attached to a computer, it is even possible
to access TotalMix FX, the built-in mixer, to create
patches and mixes before the signal is passed on to the
next device.
MADI STREAM
Mixer, router, format converter, stream splitter, signal
repeater - the MADIface USB is a perfect addition to any
MADI system.
You can use it to create redundancy, for automatic failover,
and even for creating mixes with extremely low latency
between the optical, coaxial and USB 2.0 audio inputs
altogether! The MADIface USB can be easily integrated
into a broad range of applications.
In the example below, the MADIface USB is used as a
splitter to create redundancy for the signals that are
received from the stage box.
