• Auto Gain - this feature, originally introduced on the Klark Teknik DN3600 equaliser,
automatically adjusts the system gain so that the overall program level remains constant
despite changes in equalisation. The left encoder enables or disables this feature. If set to
“No” then the graphic EQ gain trim (operated by the centre encoder) is entirely manual in
operation. If set to “Yes”, then as the graphic EQ faders are moved, the gain trim will
automatically be adjusted to compensate for the overall (average) level change. At any
time, the display over the centre encoder will show the actual gain trim being applied, and
this can always be adjusted manually (even when Auto EQ is active).
• Auto-EQ - Available only if the optional DN6000 interface is fitted, and a Klark Teknik
DN6000 Real Time Analyser is connected to the DN9340E master. Use the 16-way ribbon
cable (supplied) to interconnect the units, linking the DN9340E Expansion Slot 2 to the
DN6000 Data Output connector.
This function enables automatic room equalisation based on an audio spectrum from a DN6000.
Note that the DN9340E auto equalises on the basis of a captured DN6000 ‘snapshot’; it does
not auto-equalise in real-time. The Helix unit generates a reciprocal response curve that
compensates for peaks and troughs in the snapshot audio spectrum, so creating a overall flat
response.
Auto Eq defaults to ‘No’. To select Auto Eq, turn the right encoder clockwise. An AutoEq soft
key is added below ‘Menu’ and you are prompted to set the graphic EQ response to a 1/3
octave symmetrical response (Q = 7.8), unless this is already set, as this is the only response
that matches the filtering in the DN6000. Turn the centre encoder clockwise to confirm, or the
left encoder clockwise to cancel Auto EQ. To capture the ‘snapshot’ audio spectrum, press the
AutoEq soft key.
In remote control applications, any slave unit can have the audio spectrum snapshots captured
by the master unit. A slave DN9340E cannot capture snapshots from a DN6000 connected
directly to it.
EQ - Flat page
This page allows the graphic EQ faders to be quickly reset to their unity gain position. To
flatten the response, turn the centre encoder clockwise, then turn the right encoder clockwise
to confirm. Pressing any other button will abort the sequence.
