IMX644 Manager Owner’s Manual

What is IMX644 Manager?
IMX644 Manager is application software that lets you make detailed parameter settings for the IMX644. IMX644 Manager has the
following functionality.
• Edit the IMX644’s parameters
When connected online with the IMX644, you can perform detailed editing of the IMX644’s parameters in real-time. Edited settings can be saved as a file.
You can use IMX644 Manager to edit offline even when not connected to the IMX644 online. However, some parameters are saved
only in the IMX644, so operation when editing offline will differ in some cases from operation when editing online (e.g., channel
levels and GPI settings). As far as possible, you should use this software when connected online with the IMX644.
• Send files of settings to the IMX644
Files of settings that you saved using IMX644 Manager can be sent and loaded into the IMX644.

• Priority Ducker Key Source Select
When a signal is applied to the specified MONO INPUT channel, the level of all STEREO INPUT signals assigned to the same
output are reduced to allow announcements made via the MONO INPUT channel to stand out clearly from background music or
other program material, for example. When input to the specified MONO INPUT channel ceases, the level of the other “ducked”
channels returns to normal.
1 [MONO 1]–[MONO 6] check boxes

These turn on/off the Priority Ducker function for each MONO INPUT channel. These check boxes are linked with the [PRIORITY] buttons of the INPUT screen. The default setting is OFF for all channels.
NOTE

• If this is turned on for more than one MONO INPUT channel, an audio signal being input to any MONO INPUT channel for which this
setting is turned on will reduce the volume from the STEREO INPUT channel that is being input to the same output channel.

returns to its original volume during breathing spaces or between words, increase the Release Time so that the STEREO
INPUT audio signal does not come back inappropriately.

channels fades in and returns to normal.

IMX644 Manager Owner’s Manual

NOTE

• If this is turned on for more than one STEREO INPUT channel, the lowest-numbered channel will take priority, and the volume from
other STEREO INPUT channels will be faded-out.

• Feedback Suppressor
The Feedback Suppressor effectively controls feedback by identifying the feedback frequencies produced by factors such as the
acoustics of the venue and the characteristics of the signal path. The Feedback Suppressor includes static filters that are set based
on analysis of each MONO INPUT channel, and dynamic filters that dynamically suppress feedback when it occurs on the specified
MONO INPUT channel.
By default, the Feedback Suppressor is turned on for all MONO INPUT channels. The static filters are unset.
NOTE

• By default, the Feedback Suppressor is turned on for all MONO INPUT channels. Even though the static filters are unset, the dynamic filters
are still operational so be sure to turn the Feedback Suppressor OFF before using sine waves or test tones to test or calibrate the system.
• Feedback Suppressor settings will be stored in the unit’s 16 memories.
• Static Filter analysis can also be performed from the IMX644’s panel. For details about the analysis procedure on the IMX644, refer to the
IMX644 owner’s manual.

6 [MONO 1]–[MONO 6] check boxes

These turn on/off the Feedback Suppressor for each MONO INPUT channel. These check boxes are linked with the [F.B.
SUP] buttons of the INPUT screen.
7 [Automatic Setup] button

This consecutively tests each selected MONO INPUT channel and automatically makes the appropriate static filter settings.

To ensure optimum feedback suppression be sure to perform the measurements under the same conditions that will prevail
during actual operation (microphone and speaker positions, etc.).
1. Set up the microphone at least 5 meters away from the speakers.
2. Adjust the output level of the power amplifier.
While speaking or singing into the microphone gradually raise the output level of the power amplifier to the level that will be
used in actual operation. Also make sure that feedback does not occur when you clap your hands near the microphone.
3. Make sure the area being measured is silent.
4. Click the [Automatic Setup] button to begin the measurement.
The dialog box shown at right will appear while the static filter measurement is
being performed. When the measurement is completed, the dialog box will close
and the results of the measurement will be applied to the static filters.

NOTE

• If high-volume sound is produced, an error has occurred during measurement. If this occurs click the [CANCEL] button to abort the measurement. Before performing the measurement again, try changing the location or orientation of the microphone and speakers, lower the
amplifier output, then repeat the procedure from step 1 above.
• If an error message appears, an error has occurred during measurement. To prevent damage to the equipment the measurement will be
aborted and the erroneous data discarded. If this occurs try changing the location or orientation of the microphone and speakers, lower the
amplifier output, then repeat the procedure from step 1 above.
• Static filter measurement may not be successful if the overall level is too high or the microphone is too close to one of the speakers.

• MEMORY Assign
Of the sixteen memories specified in the MEMORY screen, any four can be assigned to the front panel MEMORY [A]–[D] buttons.
When you click the name shown beside each button [A]–[D], a list of the assignable memories will appear. Select the memory that
you want to assign to each button [A]–[D].
When you click a button [A]–[D], the memory assigned to that button will be recalled and the parameter settings will be switched
accordingly.
This is the same function as the IMX644’s MEMORY [A]–[D] buttons.
NOTE

• You may assign the same memory to more than one button. If you select a button to which the same memory has been assigned, one button in the priority order of [A]–[D] will be selected. If you want to recall memories while connected online with the IMX644, use the
[A]–[D] buttons in IMX644 Manager; not the IMX644’s MEMORY [A]–[D] buttons.

GPI screen
Here you can specify the memory that will be recalled for each input port of the GPI connector, and the open/closed status for each
output port.

NOTE

• The GPI connector is a D-sub 25-pin connector for GPI (General Purpose Interface), used to input and output control signals. The IMX644
has eight input ports and eight output ports, plus a dedicated output that indicates the unit’s power-on/off status.
• For details on the GPI connector’s specifications and example circuits, refer to the IMX644 Owner’s manual.

• GPI Input Terminal
Applying an appropriate input to one of the rear-panel GPI input ports recalls the assigned memory. For each input port, you can
specify the memory that will be recalled.
By default, memories 1–8 are assigned to input ports 1–8. If you want to change these assignments, click the Memory field of each
input port and select the desired memory from the list that appears. Select [NONE] if you don’t want to make an assignment.
• GPI Output Terminal
Here you can specify the open/closed status of each output port for each memory. This allows you to change the open/closed status
of the GPI connector’s output ports by recalling a memory.
By default, all buttons are off (gray); i.e., open. If you click a button to turn it on (green), that output port will change to the closed
state.
Click a name field to access the “Name of GPI OUT” dialog box, where you can edit the name of the output port.

NOTE

• You can also assign memories to the front panel MEMORY [A]–[D] buttons and use them to recall memories. In order to do this, you’ll
need to make memory assignments in the MEMORY ASSIGN field of the MISC screen (page 30).
