Mix Functions
The IMX644 mix functions can be programmed and edited in detail using the IMX644 Manager installed on a computer (page 7). The

■GAIN

The gain of the mono input channel head amplifiers can be indi-
vidually adjusted and displayed.

■INPUT EQ

The parameters of the input channel equalizers can be individu-
ally adjusted and displayed. The parameters available for each
channel are listed below.
MONO INPUT CHANNEL
STEREO INPUT CHANNEL

■MATRIX

The MATRIX allows individual input channels to be assigned to
any of the mixer’s output channels. The assignments are shown
on the display. The initial default settings are: send assignments
to all output channels are ON, with only OUT1 assigned to the
REC OUT channel. The send levels from individual mono input
channels to the output channels can also be adjusted and dis-
played.

■Temporary Matrix Assignment

Changes

The panel controls can be used to temporarily turn on the output
assignments of individual input channels, as follows.
1Set all OUTPUT channel level controls to “0”.
2Set the level of the INPUT channel to be
assigned to “10”.
3Press and hold the MEMORY button correspond-
ing to the output channel you want to assign the
input channel to for longer than 3 seconds while
rotating the INPUT channel level control towards
“0”.
4The corresponding MATRIX indicator will light.
5Repeat for other channels as required.
NOTE
•Output assignments made in this way are only temporary and
will not be saved to memory. If power to the unit is turned
OFF and then ON again the memorized settings prior to
making the changes as described above will be recalled.
