Your processor contains a battery backed up real time clock that can maintain the current time and date even
when the power has been removed. This allows users to switch between presets at specific times of the day or
week. This is very useful on a multi-format radio station where one processing preset may not suit all of the for-
mats of music that are broadcast.
The easiest way to control the dayparting is with the remote control application which is described elsewhere in
this manual but the use through the front panel menu system is described here.
The schedule menu contains the following options:
The TIME
Daypart ON/OFF control
Dayparts 1-4
Dayparts 5-8
Setting the time (the processor's system clock)
Setting the time is quite simple. Select the Day, Hour, Minute or Seconds and rotate the Knob until you get to
the desired setting. The Seconds can not be adjusted, only reset to 0 seconds as the knob is rotated.
There is also a clock calibration parameter, which allows a +/- 3 second correction factor to be applied at mid-
night each day to account for real time clock inaccuracies.
Daypart ON/OFF
enables or disables the dayparting.
The
dayparts 1-4 and 5-8
options drop you down into two further menus. Each containing four dayparts.
For each daypart you can enable or disable it and with the same control set the preset to switch to when the
daypart triggers (when the daypart start time matches the system clock).
You can also set the start time (trigger) of each daypart and set the length that the daypart shall be (the time the
trigger shall remain in force). The start time has a day option and this can be set to ALL which would mean that
the daypart would trigger every day at the specified time. If the length is set so that the trigger will carry across
midnight then the trigger will stop at midnight. TRIGGERS DO NOT CARRY ACROSS DAYS.
The dayparts can be layered so that one can override another. Let's say the default preset was U1:MAIN
PRESET and this was on the air all of the time. We want to change the preset from 7AM to 10AM every day of
the week to F2:CHR and then from 10AM to 12PM we want U4:NEW PRESET and then back to F2:CHR until
5PM.
Rather than setup the dayparts as
DPO: F2:CHR - ALL 07:00 - 03:00
(factory preset 2 to run from 7AM everyday for 3 hours)
DP1: U4:NEW PRESET - ALL 10:00 - 02:00
(user preset 4 to run from 10am everyday for 2 hours)
DP2: F2:CHR - ALL 12:00 - 05:00
(factory preset 2 to run from 12pm everyday for 5 hours)
We could instead setup the dayparts as
DPO: F2:CHR - ALL 07:00 - 10:00
(factory preset 2 to run from 7AM everyday for 10 hours)
DP1: U4:NEW PRESET - ALL 10:00 - 02:00
(user preset 4 to run from 10am everyday for 2 hours)
which saves a daypart position.
By carefully selecting the default preset and overlaying dayparts we are able switch presets significantly more
than you first think you will be able to.
