Analog Audio Options
Up to 4 individual analog audio input signals may be transported over the COFDM transport signal. This
accommodates the industry standard Channel 1 and Channel 2, Left and Right side audio circuits. Two
on-board 6 pin audio connectors are wired to the Strata TX circular panel audio connectors for connection
to customer supplied audio sources.
Note:
Where an FMT is installed in a Strata TCU housing (d analog transmission), analog audio
input signals may be bridged to one or both FMT audio inputs in addition to being connected to the
MPEG encoder analog audio inputs. This option accommodates simultaneously distributing analog audio
input signals to both FMT (analog) and MPEG encoder (digital) modules. The current Strata TX design
handles impedance matching in the FMT module by terminating (FMT only) or bridging (FMT + MPEG
encoder) audio input signals connected to the FMT module.
Depending on whether one or two analog audio channels are required for analog and/or digital mode
operation, one or both audio input channels (two audio circuits per channel), all combinations of analog
audio only operation can be accommodated by distributing the audio input signals to either or both FMT
and MPEG encoder modules. See the sketch on the following page to view these options.
