Audio Format Conversion
Professional audio usually requires balanced audio signals that are less prone to interference due
to the differential signal setup. When using unbalanced and balanced signals at the same setup,
amplification or attenuation is needed to match the levels. An Audio Transcoder (FC-4208 in this
case) can be used for this purpose and for signal conversion as well, as shown in Figure 12.
Perform the following steps (as necessary):
1. Connect one or more balanced audio sources to Channel 1 and Channel 2 XLR inputs of the
FC-4208.
2. Connect one or more unbalanced audio sources to Channel 1 and Channel 2 RCA inputs of
the FC-4208.
3. For unbalanced audio distribution, connect the outputs of the machine to an audio distributor
(Kramer VM-50A for example.)
4. For balanced audio distribution, connect the outputs of the machine to a balanced audio
distributor (Kramer VM-1110 for example.)
5. Operate sources, acceptors and your machine.
6. Use the front panel control functions if necessary (see section 9 for more details).
