Transmitter site Unit: AAC or L2 Receive
Use 48 kHz sample rate
10.4 Multi Codec connections
Sometimes one Xstream will need to connect to two other units simultaneously. The Xstream's
L3 Dual/Mono Receive mode allows for considerable flexibility in this regard. In all of the
following cases the Bit Rate and Sample Rate must be matched on all three units.
A single Xstream can receive Layer 3 mono from two sites as shown below:
Xstream C
Receive = L3 Dual/Mono
Xstream A
Transmit = L3 Dual/Mono
Xstream B
Transmit = L3 Dual/Mono
A Zephyr Xstream set to L3 Dual/Mono can receive one channel from
each of two remote Zephyrs. Each remote unit would be set to L3
Dual/Mono Transmit.
If Xstream A is dialed from "Line 1" to Xstream C's "Line 1," then Xstream
A's channel A audio would be present at Xstream C's channel A output.
If Xstream B dialed from "Line 1" to Xstream C's "Line 2" then Xstream B's
channel A audio would be present at Xstream C's channel B output.
Return feeds to A and B can be made using G.722 or L3 Dual/Mono.
Transmitting mono to two sites is also easily accomplished. In the above scenario Xstream C
would use L3 Dual/Mono for Transmit. Xstreams A and B would be set to L3 Dual/Mono receive.
If Xstream A were connected to "Line 1" of Xstream C, it would receive the channel A audio from
C.
If Xstream B were connected to "Line 2" of Xstream C, it would receive the channel B audio from
C.
