scheduled deviations in the station’s format during the
broadcast day. A station might deviate from jazz music to
a big-band segment, for example, or from music to regularly
scheduled talk programming or take a 5-minute satellite-
delivered news feed on the hour.
From the
Processor/Day-
part
menu, enter a pro-
cessing
Preset
that you
have selected for the
scheduled programming
segment. You may select one or more
Days
of the week that
the segment will air, and the
Hour
and
Min
(minute) it begins,
AM
or
PM
. In this example, the station airs a religious
roundtable discussion on Sunday at 11:00AM. A second
daypart, to return to the station’s music format, will have
been set for noon.
Once a programmed daypart begins, it will continue indefi-
nitely. This makes it important to set up your ‘normal’ pro-
cessing as a daypart as well, programming the scheduler to
switch back when the other daypart ends.
Processor Bypass
The
Bypass
mode simply removes the entire audio pro-
cessing function from the program signal path.
Test Oscillator
Engaging the
Test Oscillator
disconnects program audio from
the input of the audio processing section and allows you to
feed this point with a tone. Default is
Off
, of course, but
the oscillator tone may be fed to the left
L only
or right
R only
channels independently, or to both
L+R
program
channels.
The
Frequency
and the
Level
of the tone are both adjustable
from this menu. A
Level
setting of
–10dB
is equivalent to a
console ‘zero-VU’ level and will center the gain-riding AGC
function. Depending on the processor setup, you may see
little or no meter action with a tone, as subsequent stages
respond primarily to program peaks.

THE RDS ENCODER
Navigate to
Setup/Outputs/Stereo Generator/RDS Encoder
.
Subcarrier Injection
The RDS subcarrier is enabled, or not, in
Input Sources
under
the Main Menu (see Page 9). Set
RDS
to
None
to disable the
RDS subcarrier under
Primary Source
or
Backup Source
1
or
2
.
The
RDS Injection
submenu accesses the
Injection
slider, which
sets the percentage injection of the RDS subcarrier with re-
spect to total carrier modulation. The default value is
5%
.
Static RDS Data Entry
RDS Data
is a data-entry field for the ‘Internal’ fixed RDS
messaging.
A
PI
hex value should
always be entered. This
is essentially the sta-
tion’s ‘digital address,’
used by some consumer
radios to auto-tune to a station’s translator(s).
Similarly,
PTY
identifies the station’s format. Radios use
this to search-out and tune-to a listener’s program prefer-
ences.
PS
, the Program Service Name, can be either a static, 8-
character station ID:
LIVE 105
, or a slogan or promo up to
128 characters (including spaces). Messages exceeding 8
characters will automatically parse and scroll across the
faceplate of any RDS receiver:
BOSS-FM,
ON THE AIR
EVERYWHERE
.
The same applies to
RT
, or Radio Text, which is a 64-
character scrolling message that can be read on some radi-
os. This usually lists the station’s Website and phone num-
ber, or promotes an upcoming event.
