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), the feeds would have the
left and right channel of each program 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 T1L as a
summed mono program and the other stereo program would be sent out T1R 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
network controlled 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.
A seventh mapped target, TMAP7, is reserved for
broadcasts sent by
the Amb-OS network. If it is left on its default (T2-Stereo), the AMR-100 will put this
program out on T2 in stereo. Even when TMAP7 is
to a port, it also has to be
enabled from the front panel. See the Emergency Enable in the
section.
Setting TMAP targets can be done through the front panel menu, see
through the HTML command interface, see the
in the HTML command
interface section.
The mapped names are with their default mapping:
TMAP1 – T1 (stereo)
TMAP2 – T2 (stereo)
TMAP3 – T1L (mono)
TMAP4 – T1R (mono)
TMAP5 – T2L (mono)
TMAP6 – T2R (mono)
TMAP7 – T2 (stereo) [
program target]
can use the hardware port (T1, T2, T1L, etc.),
because the connections to the air chain stay the same. However, if different configurations
