FC-202NET - Getting Started
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerav.com/downloads/FC-202Net to check for up-to-
date user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer FC-202NET away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
2.2 Safety Instructions
Caution:
There are no operator serviceable parts inside the unit
Warning:
Use only the Kramer Electronics power supply that is
provided with the unit
Warning:
Disconnect the power and unplug the unit from the wall
before installing

2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

This chapter comprises the following sections:
Connecting the FC-202NET (see Section 5.1)
Connecting the inputs (see Section 5.2)
Connecting the outputs (see Section 5.3)
5.1 Connecting the FC-202NET
Always switch off the power to each device before connecting it to your
FC-202NET. After connecting your FC-202NET, connect its power and
then switch on the power to each device.

To connect the FC-202NET as illustrated in the example in Figure 2:
1. Connect a balanced audio source, (for example, a microphone) to the 3-pin
Input 1 terminal block.
2. Connect a balanced audio source, (for example, a multimedia player) to the
3-pin Input 2 terminal block.
3. Connect a Dante audio network source via the network to the Dante RJ-45
connector.
4. Connect the Output 2 3-pin terminal block to the first balanced, line-level
audio acceptor, (for example, a recording device).
5. Connect the Output 1 3-pin terminal block to the second balanced, audio
acceptor, (for example, an amplified speaker).
6. Connect the power adapter to the FC-202NET and plug the power adapter
into the mains power supply.
5.2 Connecting the Inputs
Your FC-202NET is provided with a 3-pin terminal block for each input channel.
This connector can accept either a balanced or an unbalanced connection,
however, some modifications must be made for an unbalanced connection. See
the next two sections for instructions on connecting the NetAV I/O 2x2 to its input
source.
5.2.1 Connecting Balanced Inputs
When using a balanced input source and connector, you must ensure that the hot,
cold, and ground pins of the connector are matched up to the +, –, and ground
pins of the FC-202NET terminal block connector respectively. The following
diagrams illustrate how to connect standard XLR and 6.5mm phone jack.

5.2.2 Connecting Unbalanced Inputs
When using an unbalanced input source, a jumper must be added between the
negative (–) and ground terminals. The unbalanced source is connected to the
positive (+) and ground terminals.
Note: A jumper is required for connecting an unbalanced input.

5.3 Connecting the Outputs
Your FC-202NET is provided with a 3-pin terminal block for each output channel.
This connector offers a balanced output to interface with the input of another
device.
Connection methods for balanced and unbalanced outputs are identical as the
methods for inputs as referenced in Section 5.2.

7 Troubleshooting
No output on one or both channels; the power indicator is lit.
Check that Dante has been configured properly.
The input is not sent to another network device or the sound is distorted.
Check that Dante has been configured properly. Check that the inputs are properly
configured. If the input source requires pre-amplification or phantom power, see
Section 6.
