Audio Playback Description
Analog
The analog outputs are the main outputs and all other outputs (digital and IP streaming) are
paired to the analog outputs. That means you cannot have any more than four mono
programs playing. With mono programs playing on Port 1-L and Port 1-R, all three digital
outputs for Port 1 will have the mono program playing on Port 1-L on its left channel and the
mono program on Port 1-R on the right channel. Port 2 does the same. With a stereo program
playing out the analog port, all three digital outputs for that port will have the same stereo
program playing.
You can have the following configurations:
Stereo (Port 1-L&R, Port 2-L&R)
1 stereo program on Port 1-L&R and 2 mono programs: 1 on Port 2-L and 1 on Port 2-R
2 mono programs: 1 on Port 1-L and 1 on Port 1-R and 1 stereo program on Port 2-L&R
4 mono programs: 2 on each port – 1 on Port 1-L, 1 on Port 1-R, 1 on Port 2-L and 1 on
Port 2-R
The AMR-100-I will mix a stereo program to mono when you send it out a mono port. A
stereo program sent out Port 1-L will have the left and right mixed to mono on that port.
Digital
The digital outputs mirror the analog outputs. Whatever comes out the analog comes out on
all the digital ports. So, two mono programs coming out Port 1-L and Port 1-R will come out
the AES-EBU, SPDIF, and OPTICAL as two programs, one on the left and one on the right.
Also, you cannot send any audio out the digital without it going out the analog ports. Port 1
and Port 2 can be different programming, but the audio coming out the analog outputs of Port
1 also will come out the digital outputs (AES-EBU, SPDIF, and OPTICAL) of Port 1. The
same is true for Port 2.
Streaming
The AMR-100-I can stream audio out the Ethernet port, but, like the digital outputs, they
must have an associated analog output. The Ethernet stream is always in stereo, which means
you can play a program out Port 1-L and stream that same program out the Ethernet port. The
analog output on Port 1-L will be mono and mix the stereo to a mono signal, but the output of
the Ethernet will be in stereo.

NOTE
All audio playback must done by an internal playlist or a trigger (see Playlist).
There is no method to playback audio from the front panel.
NOTE
All the outputs for each port (analog and digital) are always the same.
Whatever comes out of Port 1 analog (stereo or mono) comes out the digital
ports (AES-EBU, SPDIF and OPTICAL for Port 1. You CANNOT have one
thing come out of the digital ports for Port 1 and something else come out of
the analog for Port 1.
