10.2 OnAir 500 and RCS System
RCS is a company specialized in radio playout systems. The playout system
is PC (Windows) based, and offers a user interface allowing graphical sched-
uling of the elements of a radio broadcast. Songs, adverts, sound effects,
jingles etc. are all stored on harddisk, allowing entire shows to be prepared
and scheduled in advance, alleviating the need for the DJ to change CDs or
cartridges etc. during the live broadcast.
A simple RS232 serial protocol exists to allow radio mixing consoles to be
integrated into an RCS system. A basic level of integration would support,
for example: Lifting a designated fader on the console invokes the next
scheduled element to be played.
10.2.1
Connections and Setup
1.
Two cables connect the RCS PC to the OnAir 500 console:
A TDIF cable carrying eight channels of audio (in four stereo pairs), and a
standard 9-pin serial cable, connecting the COM port of the PC to the RS232
port of the OnAir 500, carrying the track sequencing information.
2.
Select a clock frequency on the OnAir 500 to match the sampling rate of the
RCS PC. That is, if the audio was recorded at 44.1 kHz, you will need to go
to the
Clock Source
setup page and select
Internal 44.1kHz
(chap-
ter 4.5).
4.
RCS must be enabled on the console using the
RCS Setup
page;
do not
change the mode on the PC because this does not communicate the change
to the console
.
Please note that you cannot enter this menu whilst the RCS
system is playing.
RCS utilizes up to four console channels named A, B, C, D. Select one of the
four RCS modes that are named according to the channels involved:
ABCD
,
ABC
,
ABD
, and
AB
.
Once you have selected a mode it will take a few seconds for the
ON
and
OFF
buttons to refresh.
A further mode (AB.net) appearing on the pull-down menu of the RCS PC
application is not used.
5.
The
RCS Channel Sel
setup page allows you to choose which channels
on the console correspond with which letters.
Default settings:
Track A on the RCS sequencer comes through on channel 1,
track B comes through on channel 2, C on channel 3, and D on channel 4.
6.
To hear the triggered track, the correct TDIF stream must be assigned to the
RCS channel. The channel audio corresponds to the RCS channels named
A...D. Bring the RCS stereo TDIF signals onto the console channels using
the
Assign Channel
setup page.
