Installation
The following installation chapters guide you through
the hardware and network installation process. Refer to
the connection and indicator details of chapter 1.3. The
button, indicator and connector numbers are indicated
as (x).
2.1 Mechanical
installation
The IP Audio Interface device can be either built-in a
19”-frame using a
19”-mounting frame or shelf (not
included) or used stand alone.
2.2
Network (step 1)
Plug a standard (straight) network cable into the
network port (13) of the IP Audio Interface and the
other end into a switch of your network.
Use a crossover network cable for a direct connection to
your PC.
2.3
Audio outputs (step 2)
Connect the Audio Output 1 (9) and/or 2 (8) to the
amplifier or mixer input(s). Audio Output 2 also
generates a pilot tone.
When powered up for the first time, the device will
announce its IP address in English. Connect an
amplifier with loudspeaker or headphone to the device
in order to hear the announcement. Keep a pen and
paper ready to write down the IP address.
2.4
Power supply (step 3)
Connect the power supply to the power supply input
connector (17). Optionally connect the back-up power
supply to the power supply input connector (16).
The device will start-up and the eight green Control I/O
LED’s (3) go ON and the green and red status LED’s (2)
flash alternating.
2.5
IP address (step 4)
The IP Audio Interface will search for a DHCP
(Dynamic Host Configuration Protocol) server to get an
IP (Internet Protocol) address. As soon a valid and free
IP address is found, it will be announced via the Audio
Outputs 1 and 2 (9 and 8). Write down the IP address.
Example: 192.168.0.12 (Voice: one nine two…).
The eight green Control I/O LEDs (3) and red status
LED (2) go OFF and the green status LED (2) switches
ON.
The IP Audio Interface is now ready for configuration,
but it is recommended to set a static IP address, see
section 3.1.
2.6
Troubleshooting (step 1..4)
If no DHCP server is found then the built-in IPzator
function will search the network for a free IP address.
This can take up to 5 minutes.
If the IP address is not announced, check:
•
if the green LED on the network port used
(13 or 14) is ON.
When OFF, check your network cabling.
•
the green status LED (2).
When OFF, check the power supply cabling.
If the device still fails revert to the factory default
settings by pressing the reset button (1) between 5 and
10 seconds while it is powered and repeat the previous
steps 1 up to 4.
2.7
Audio Inputs 1/2 (step 5)
Connect the Audio Inputs 1 and 2 (11 and 10).
Both balanced Audio Input 1 and 2 are independent
from each other, but will always be routed together.
Audio Input 1 is selectable between microphone and
line level. If set to microphone sensitivity, it can also do
microphone presence supervision.
Audio Input 2 is a line level input. It can detect a
20 kHz pilot tone which is generated by the connected
audio source to supervise the connection.
