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 - this section enables automatic room equalisation when the Helix unit
is used with a Klark Teknik DN6000 Real Time Analyser. This function is only
available when the optional DN6000 interface is fitted.
After the Auto-EQ function is selected by setting the menu option in the
Automatic Features menu page, the user will be prompted to confirm that the
graphic EQ response will be set to a 1/3 octave symmetrical response (Q = 7.8) if
this has not already been set, as this is the only response that will match that of the
filtering in the DN6000. If 'No' is selected then the user is returned to the
Automatic Features menu page without the Auto-EQ function being enabled. If
'Yes' is selected then the Auto-EQ function is enabled, and the graphic EQ
response is changed to the 1/3 octave response, the user is then returned to the
Automatic Features page. Additionally, the third soft key from the top will now
be labelled 'AutoEq' to allow a snapshot of the DN6000's audio spectrum
frequency domain measurement to be captured by the Helix unit when this key is
pressed.
The Helix unit will then generate a reciprocal response curve to
compensate for any peaks or troughs in the DN6000's measurement in order to
create a flat response across the audio spectrum.
In remote control applications, any slave unit can have the audio spectrum
snapshots captured from a DN6000 connected to the master unit applied to it. A
slave DN9340 cannot however capture snapshots from a DN6000 connected
directly to it.
EQ - Flat page
This page allow 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 key will abort the sequence.
pressing this allows an individual fader insert or a selected block of
faders to be switched in and out of circuit.
