Figure 5 shows the panel connections for the USB-A2B interface. The
Optical IN
is not active.
Optical OUT
is
typically used to output test signals. The USB-A2B interface is powered by an external 5V supply through a
micro-USB Type B connector. A 5V 2A USB power supply for this purpose is included with the USB-A2B.
Figure 6 illustrates how the UMIK-X is connected. Note that the power supply is equipped with a USA-style pair
of power pins that fold out from the body. Adapters for UK, EU and AU power are included and can be fitted to
the supply by folding down the pins and sliding the adapter into the slot until it locks.
Here is a standard procedure for getting connected:
1.
Connect a free USB (2.0 compatible) port on your computer to the Type B port on the USB-A2B.
2.
Connect the
“B”
A2B port on the USB-A2B
to the “A” port on the first
UMA-4 module.
3.
Connect the
“B”
port of the first UMA-4
module to the “A” port on the second
module (if present).
4.
Repeat for the third and fourth modules (if present).
5.
Plug in the provided 5V 2A USB power supply to mains power. Connect the USB port on the power
supply to the micro USB power port on the interface.
All microphone modules must be connected before applying power to the USB-A2B interface,
otherwise the modules will not be recognized.
The power supply must supply adequate power to the modules. We recommend using the provided
power supply (5V 2A) or equivalent, and not using e.g. a computer USB port to supply power.
