It is also possible to recall from the Memory View (see p. 17).

10.2. Writing Data into the Preset Memory

Select [Memory → Store → Memory (1 – 16)] from the menu.

It is also possible to write on the Memory View (see p. 17).

51

52

10.5. Setting the Preset Memory Recalled When Power Is Turned On

Select [Memory → Power ON → Last Memory/Memory (1 – 16)] from the menu.

53

11. STEREO LINK SETTINGS

11.1. Stereo Link Functions

• Performing Stereo Link settings for adjoining channels (such as Channels 1 and 2, 3 and 4, and 5 and 6)
causes the compressor/auto-leveler and filter signal processing parameters to be linked. If a signal
processing parameter for either channel is modified, the corresponding parameter of the other "linked"
channel also simultaneously changes.

• The Stereo Link function can be independently set for input and output sides. Enable the Stereo Link setting
when wishing to make the settings of both left and right channels identical, such as when a joint input is
received from a CD player or other stereo sound source and joint output is sent to a tape recorder or similar
stereo equipment.

11.2. Stereo Link Settings

• Click and select the signal processing boxes of the channels you want to "link," then select [Edit → Enable
Stereo Link...]. Input and output sides can be set by clicking the signal processing box of each
corresponding side.

• Parameters of the linked channel with the lower channel number (e.g. Channel 3 when Channels 3 and 4
are stereo-linked) are copied to the channel with the higher number.

• Signal processing boxes are linked if the Stereo Link setting is made.

• "Stereo-linked" compressors/auto-levelers correspond directly to each other in operation as well.

11.3. Stereo Link Reset

To reset the Stereo Link setting, click and select any signal processing box of the desired channel, then select
[Edit → Disable Stereo Link] from the menu.

11.4. Stereo Link Setting Restrictions

• If you assign the bus from the stereo-linked input channel to the stereo-linked output channel, both left and
right channels are simultaneously assigned. For example, when Input 1 is stereo-linked to Input 2, and
Output 1 is linked to Output 2, if Input 1 is assigned to Output 1, Input 2 is also similarly assigned to Output

2. However, you cannot assign Input 1 to Output 2 or Input 2 to Output 1.

• Stereo-Link settings cannot be performed for the output channels that have employed the crossover
function. Conversely, the stereo-linked channels cannot use the crossover function.

54

12. LEVEL MONITOR VIEW

The Level Monitor View window permits monitoring of the D-901 mixer's input and output signal levels, the
current NON/Ducker priority level, and the mixer's cooling fan operating condition while a connection is being
established between the D-901 and the PC for communications. You can show or hide the view by selecting
[View → Level Monitor View] from the menu. However, this menu selection is only valid while the D-901 and
the PC are in communication mode.

Indicates input/output signal levels as follows:

Lights red when a signal level is over 17 dB above the rated level.
Lights green when a signal level is between –40 dB above and 17 dB below the rated level.
Extinguishes when a signal level is under –40 dB below the rated level.

Lights yellow if the compressor
reduction function is enabled.

Note

If auto-leveler mode is set for
input channels, their
corresponding indicators are
not displayed.

Displays the current Ducker
priority level for each auto­mixing group.

17. SETTINGS REQUIRED WHEN THE D-981, D-983, OR D-984VC IS USED

17.1. The Outline of the D-981, D-983, and D-984VC

Mounting the optional D-981 or D-983 Remote Control Module, or the D-984VC VCA Control Module in the D­901 Mixer permits the D-901's memory selection, input/output volume control, channel ON/OFF operations,
and stereo input selection (the D-936R or D-937SP must be installed) to be remotely controlled from external
equipment. Also, status data of the D-901's memory selection, channel ON/OFF and stereo input selection
(the D-936R or D-937SP must be installed) can be transmitted to external equipment. For mounting the D­981, refer to the instruction manual included with the D-901.
External remote control is performed by shorting terminals 1 – 8 (1 – 24 for the D-983) to the C terminal.
Taking the contact input setting as an example, when terminals 1 – 8 are assigned to preset memory Nos. 1 –
8 respectively by means of the memory selection function, if each terminal is shorted to the C terminal, preset
memory Nos. 1 – 8 can be recalled.
The contact input terminals 1 – 8 are preset to recall the "Preset Memory 1 – 8" when activated, the contact
output terminals 1 – 8 are preset to provide make contact when the "Preset Memory 1 – 8" is recalled, and
other input and output contacts are preset to "None" or "Normally break." By changing the settings on the
contact input and output setting screens, many different functions can be assigned to the contact input and
output.
