6.7. Clear Down Sequence
Because of the comprehensive facilities available on the DN9340E, 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
See Section 8 for further details on storing and recalling memories.
B. Select each type of EQ, and bypass them in turn as follows:
1 Press GRAPHIC, then BYPASS (the TYPE bypass LED illuminates), PARAMETRIC, then BYPASS, and
so on for DYNAMIC and FILTERS.
2 Finally, press HOME (SETUP), press the soft key labelled Delay/Gain and set the delay and gain to
zero values.
3 Press HOME (SETUP) 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:
1 Press HOME (SETUP), then select the soft key labelled Delay/Gain. Set delay and gain to zero.
2 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.
3 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.
4 Press DYNAMIC. Press the soft key labelled Menu five times to display the EQ FLAT menu page.
Turn the centre encoder clockwise, then the right encoder clockwise to confirm.
5 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.
6 Press HOME (SETUP) to return to the home page.
