Because of the comprehensive facilities available on the DN9340, it may be important to ensure that the unit is
“cleared down” before use. Remember to clear down both channels A and B if the unit is not linked for stereo
operation. There are a number of possible strategies for this:
A. Recall a memory that contains a suitable set of default values.
B. Select each type of EQ, and bypass them in turn by pressing “GRAPHIC”, then “BYPASS” (the
TYPE bypass lamp lights), “PARAMETRIC”, then BYPASS, and so on for DYNAMIC and
FILTERS. Finally select HOME, press the soft key labelled “Delay/Gain” and set the delay and
gain to zero values. Press HOME again, and the unit is ready to use and set to provide a flat
response. This method is fast, but has the disadvantage that when the BYPASS function is
deselected for a given type of EQ, the previous settings will be restored, which may not be what
is required.
C. To ensure that each type of EQ is zeroed-out and can be introduced seamlessly into circuit,
follow this sequence:
Press HOME, then select the soft key labelled “Delay/Gain”. Set delay and gain to zero.
Press GRAPHIC. Press the soft key labelled “Menu” three times to display the “EQ FLAT”
menu page. Turn the centre encoder clockwise, then the right encoder clockwise to
confirm.
Press PARAMETRIC. If parametric EQ sections exist, then press the soft key labelled
“Menu” twice to display the “Remove” menu page. Turn the centre encoder clockwise,
then the right encoder clockwise to confirm deletion of the selected parametric section.
Repeat these encoder moves until no sections of EQ remain.
Press DYNAMIC. Press the soft key labelled “Menu” to display the Lo settings page. Set
the Lo Level to 0dB. Press the soft key labelled “Select” to jump to the other section of
dynamic EQ. Set the Lo Level to 0dB. Now press “Menu” once to display the Hi settings
page. Set the Hi Level to 0dB. Press “Select” to jump back to the first EQ section. Set the
final Hi Level to 0dB.
Press FILTERS. If filter sections exist, then press the soft key labelled “Menu” twice to
display the “Remove” menu page. Turn the centre encoder clockwise, then the right
encoder clockwise to confirm deletion of the selected filter section. Repeat these encoder
moves until no filters remain.
Press HOME to return to the home page.
