6.3 Manual Controls
All IQ mixers can be manually controlled. This can be done from both a control block and from custom controls you
create on a graphics plate.
6.3.1 Manual Control from a Control Block
Use the Device menu (
!) to access an IQ mixer Control Block screen. A sample SMX-6 Control Block screen
is shown below in Figure 6.6.
All of the manual controls will be describe next. However, not all controls are available for all IQ mixers. Refer to
the control blocks in Figure 6.1 to see which controls are available for the different models.
DSPI: The Data Signal Presence Indicator is an LED on the front panel of the IQ mixer that flashes whenever
the mixer is polled. The DSPI control is used to force the indicator to stay on as an aid to the troubleshooting of
communication on the Crown Bus. Once the DSPI control is turned on, the DPSI will remain lit continuously even
if the control block for another device is selected. Turning off the DSPI control restores the indicator to its normal
function of blinking when a valid IQ command is received.
Aux: Toggles the mixer’s AUX port output on and off.
Sel: Selects the mixer so that a GDM for it is added to a graphics plate when the graphics plate is set to the
Selected mode.
Lock: When turned on, the Lock control locks the Channel 1 and 2 gain controls together for each input. But
before doing so,
all gain controls for the mixer will be set to –100 (off) as shown in Figure 6.7.
When locked, changing the level of Input 1, Channel 1 will cause an identical setting in Input 1, Channel 2.
