Timer Controls
The timer has two modes of operation, standard and auto. By pressing the
AUTO button, the timer is switched between its two modes, and the current
mode is indicated by the AUTO button light: in auto mode the light is
illuminated, while in standard mode it is not.
In either mode the S/S, RST, and HOLD buttons work as follows. When
the S/S button is pressed, it either stops or starts the timer, depending on
whether the timer is currently running or not. Pressing the RST button resets
the time to zero. If the timer is running when the RST button is pressed the
timer continues to run after resetting to zero. If the timer is not running when
the RST button is pressed it resets to zero and stays there until it is started
again. While the HOLD button is being pressed, the timer display freezes to
show the time elapsed from reset to that point; however, the timer itself
continues to count, so that, when the HOLD button is released, the display will
jump to the new elapsed time and then continue to show the updated count.
The HOLD button has no effect if the timer is not running.
In the auto mode, any faders whose selected sources have been set up by
the installer to activate timer restart will, when the fader’s ON button is
pressed, cause the timer to reset to zero. If the timer is running, the display will
again start counting up after the reset. If the timer is not running, the time will
reset to zero and stay there until the timer is once again started.
LOGIC PORTS
The console has several LOGIC PORTS which can be used to control local
machines, such as cart machines, CD players, etc., or with talent panels for mic
signals. The installer will have set up the logic ports to work with particular
inputs. When an input is selected for a fader, that fader’s functions will interact
with the assigned port as described below.
Mic Port Functions
The mic port logic functions are ON, OFF, COUGH, TALKBACK, and
ON TALLY. These are normally used in connection with a user-provided
talent panel containing switches to be operated by a mic user, often located in
the Studio.
ON Logic Input
The ON LOGIC INPUT is used to connect an external user-supplied
button to activate the microphone’s fader, just as if the fader’s ON BUTTON
had been pressed.
OFF Logic Input
The OFF LOGIC INPUT is used to connect an external user-supplied
button to deactivate the microphone’s fader, just as if the fader’s OFF
BUTTON had been pressed.
