AMR-100 Receiver
The AMR-100 signal is delivered on the same satellite and same transponder as the
classic CRC DVB signal which feeds Christian radio stations on the Unity 4000.
Consequently, installation involves simply splitting the L-Band feed coming from the
satellite dish, sending one feed into the AMR-100 and the other back into the Unity
4000. Ethernet, audio and relay connections are also simple to install.

AMR-100 Advantages
- Reliable, guaranteed delivery with the ability of the receiver to "report
home" via an internet connection.
- High audio quality which avoids several encoding/
decoding steps. As a result, the stored file will be
much more HD Radio friendly.
- Addressability ensures you'll get ONLY the program
you should receive. Last minute changes and in-state programs
need no local intervention.
- Program producers may choose to customize a program for
your station, every day. They'll have the ability to mention
the call letters of your station, rather than depending on a
local announcer to do so.
- A dedicated computer tasked with recording scheduled
feeds is no longer needed. Your programs will automatically
appear on your local network, ready to be played.
- The AMR-100 can communicate through relay closures to and
from your automation system.
This Powerful AMR-100 receiver/server can also play
back files on a schedule via its Web interface. In this
way, a station could use the AMR-100 receiver/server as
a slave to their automation equipment (triggered by time
or a relay) or as a backup playback device.
The AMR-100 receiver/server is also capable of
"streaming through" live programs via its audio
ports. Several programs from the Focus Satellite
Network and Ambassador's satellite network will
be fed via these channels.

Audio Resources |
|
Analog audio outputs | 4 balanced outputs via Neutrik NC3MBH XLR connectors |
|
Output level | 12 VRMS into 600 ohms each output (maximum) |
|
Dynamic range | 120 db (DAC specification) |
|
THD+N | -107 db (DAC specification) |
|
Volume control | 0 to –127.5 db, in 0.5db steps, independent, each channel |
|
Analog audio inputs | -none- |
|
Digital audio outputs | 2 AES/EBU serial digital outputs using one (but not both) of either a 110 ohm balanced and isolated output via an XLR type connector, or an unbalanced 75 ohm output via a BNC connector. 2 optical TORX style outputs are also provided and available simultaneously. |
|
Optional Digital audio inputs | 1 AES/EBU serial digital input using one (and only one) of either a 110 ohm balanced and isolated input via an XLR type connector, or an unbalanced 75 ohm input via a BNC connector, and 3 optical TORX style inputs. Only one of the four available inputs may be selected for use at any time. |
|
Digital audio matrixing | The AES/EBU and optical inputs are hardwired to a AKM 4122 SRC (Sample Rate Converter). This device provides 4 internal interconnection modes between the AES/EBU/ Optical I/O pins and its serial digital audio I/O pins. Further, the SRC serial digital audio I/O (clocks and data), 5 PLL derived internal clocks, and the 2 DAC serial digital audio inputs are all routed to a CPLD that can be re-configured "on the fly" providing a cross-point switch function for all serial digital audio signal sources and sinks. |
Digital Control Circuits |
|
"Contact closures" | Two sets of 6 form 1A contact pair outputs (single pole, single throw, normally open) and 4 Optically isolated inputs are provided. These input/output contact pairs are made available via two 25 pin female D-SUB connectors. Contact function and control dictated by system software. |
