Specifications
All targets need to use the audio ports as the primary target. If you want to stream a program
on your internal network on target T224.0.0.1:5004, the program also will have to use an
audio port. The AMB-OS transfer program will require you to enter which audio port you
want to use. It is possible to have four streams and use each of the audio targets as a separate
source. Thus you can have the following:
1. T224.0.0.1:5004 and using T1L as the main output
2. T224.0.0.2:5004 and using T1R as the main output
3. T224.0.0.3:5004 and using T2L as the main output
4. T224.0.0.4:5004 and using T2R as the main output
The audio coming out the mono analog targets will be summed, but the stream still will be in
stereo. This also is true for recording a live stream. To specify a target with a filename
(Tfilename.mp2) also will have to have an analog target.
Files can be played back on the audio output ports (targets) in stereo, mono, or in a
combination of that. The two stereo analog output targets can be used as described (two
stereo), as four individual mono outputs, or one stereo and two mono outputs. A stereo
program that is sent as a mono feed out either the left or right side of a target is summed into
a mono feed. Thus by sending two stereo programs out Target 1 (T1) as mono feeds (one
stereo program on the left and another stereo program on the right) would have each
program’s left and right summed together and then sent out the left or right side of the port.
The first stereo program would be sent out the left channel on T1-L as a summed mono
program and the other stereo program would be sent out T1-R as a different summed mono
program. This list provides the possible combinations.
1. Target 1 (T1) and Target 2 (T2) used a true stereo outputs.
2. T1 as a stereo output and T2 as two mono output ports (T2L and T2R).
3. T1 as two mono outputs (T1L and T1R) and T2 as a stereo output.
4. T1 as two mono outputs (T1L and T1R) and T2 as two mono outputs (T2L and T2R).
Target Maps
Mapped targets use one of six physical outputs, but can be addressed by a single name. A
live program may have a target of TMAP1 and the station can assign that to any of the six
analog targets: T1, T2, T1L, T1R, T2, T2L or T2R. TMAP0 is reserved for special programs
or emergency broadcasts (***This will be implemented in a future firmware revision). If it is
left on its default (None), the AMR-100 will not receive any of the broadcasts on that map.
TMAP0 is assigned to a port, it also has to be enabled from the front panel. See the
Emergency Enable in the Front Panel section.
The mapped names are with their default mapping:
TMAP0 – None (***Future firmware revision)
TMAP1 – T1 (stereo)
TMAP2 – T2 (stereo)
TMAP3 – T1L (mono)
TMAP4 – T1R (mono)
TMAP5 – T2L (mono)
TMAP6 – T2R (mono)
Normally programs can use the hardware port (T1, T2, T1L, etc.), because the connections to
the air chain stay the same. If different configurations would be used, you can specify a
mapped target, the target in the playlist stays the same even if the external routing is changed.
If the TMAP1 is mapped to T1L, then when the TMAP1 target is specified in a playlist, it
will play out T1L (mono). However, if you change the mapping of TMAP1 to T2 (stereo),
then when TMAP1 is used as a target, it will go out the second port in stereo.
