Quad Assignment of AES/EBU Device s
The digital I/O devices RN.331. DD, RN.332.DO and RN.333.DI provide an AES/EBU signal per each
single XLR connector.
The Quad number shown in the respective display equals 2 (t wo) Quads since each XLR connector
represents 2 (two) channels.
The channel count is (from left to right):
XLR 1
Channels 1 and 2
XLR 2
Channels 3 and 4
QUA D N *)
XLR 3
Channels 5 and 6
XLR 4
Channels 7 and 8
QUA D N+1
Left-hand QUAD No. = QUAD N (di splayed)
XLR 5
Channels 1 and 2
XLR 6
Channels 3 and 4
QUA D M *)
XLR 7
Channels 5 and 6
XLR 8
Channels 7 and 8
QUA D M+1
Right-hand QUAD No. = QUAD M (di splayed)
*) N and M always being odd Quad numbers which are displayed as the “leading” Quad number
E XAMPLE:
If t he left-hand channels of an RN.333.DI would be assigned to Quad number 1 (one) the ADD Quads
number 1 (one) and 2 (two) are occupied and the left -hand display would show Quad number
01
01
01
01
. The
next available A DD Quad number at the RN333. DI or any where else in the network would in this case
be 3 (three).
If now Quad number 3 (three) would be assigned to the right-hand channels of the RN.333.DI the
Quad numbers 3 (t hree) and 4 (four) would be occupied and the right-hand display would show
03
03
03
03
.
The next available A DD Quad number in the net work would now be 5 (five).
RN.333. DI
RN.332. DO
USO
RESTRITO
