IMX644 Owner’s Manual 17
■ OUTPUT EQ
The parameters of the independent 6-band parametric equalizers
provided for OUTPUT channels 1 through 4 can be adjusted and
displayed. The following EQ types can be specified for each
band.
The initial default settings when the P.EQ type is selected are as
follows.
■ DELAY
Sets the output channel delay time.
One of the main uses for this feature is to delay the output to sub
speakers slightly compared to the main speakers, to create a solid
frontal sonic image.
■ BALANCE
Adjusts the A/B level balance for OUTPUT channels 1 and 2.
■ Output Format (STEREO/MONO)
Specifies whether OUTPUT channels 1 and 2 deliver a STEREO
or MONO output signal. When [STEREO] is selected the left
channel signal is delivered via the A connector and the right-
channel signal is delivered via the B connector. The initial de-
fault setting is [STEREO].
■ GPI (General Purpose Interface)
• GPI Input
Applying an appropriate input to one of the rear-panel GPI
input ports recalls the assigned memory. Individual assign-
ments can be made for each input port.
• GPI Output
Recalling a memory causes a pre-assigned combination of
ON and OFF outputs to appear at the GPI output ports. The
ON/OFF combinations can be independently assigned for
each memory.
The initial default assignments for all memories are all out-
puts OFF.
■ MEMORY
Up to 16 sets of parameters can be memorized. Of those, four
can be assigned for direct recall from the front-panel MEMORY
[A] through [D] buttons. For access to five or more memories at
a time either use the IMX644 Manager application, or a suitable
external controller connected to the GPI interface.
NOTE
• MEMORY buttons [A] through [D] are initially set up to recall
the same data.
• Since the level settings for each channel are stored in the
IMX644 unit itself, be sure that the IMX644 Manager
application is online when setting up the memories.
