4. MENU STRUCTURE AND EDITING
Fig. 4.9: Setup ß In/Out
The inputs can also be linked using the parameter INSTEREO
LINK. Thus, all settings of one input can be transferred to another
input, or to all inputs.
Fig. 4.10: Setup ß In/Out
When this function is On, the display provides a warning note
that shows both the new link to be activated and the name of the
inputs that will be overwritten (black field). Use the data wheel to
edit the link to be activated (black field). The values of input A will
be transferred to the following inputs.
Tab. 4.2: In Stereo Link
When you edit a setting of any input, while a link is activated, all
edits are directly transferred to the linked inputs. In the case of the
IN STEREO LINK function, this also includes the DELAY values
(see chapter 4.3.2).
Use the parameter IN A + B SOURCE to select the type of
input signals: ANALOG or AES/EBU (digital: via input A only).
4.2.2 DLY-CORR./AUTO-ALIGN
Fig. 4.11: Setup ß Dly-Corr./Auto-Align
As the speed of sound depends on the air temperature, the
parameter DELAY CORRECTION on this SETUP page can be
used to adjust the DCX2496 to the ambient temperature, ensuring
proper delay characteristics at all times. The available value range
is from -20°C to 50°C (-4°F to 122°F)
and will be taken into account
only as long as DELAY CORRECTION is ON.
With the AUTO ALIGN function you can delay the output signal
automatically by a certain amount, so as to eliminate phase
cancellations caused by speaker alignment. For example, when
the diaphragms of several speakers are not in the same phase it
leads to cancellations due to arrival time differences. Identical
signals are radiated from different positions, so that wave crests
coincide with wave troughs. If only one of these signals is delayed,
this misalignment can be compensated.
If the arival time differences are smaller, a short signal delay
will be enough to eliminate them (SHORT DELAY). However, if
the speaker cabinets are placed several meters away from each
other, not only can phase cancellations occur but so can audible
run-time differences. To remove these, youll have to use
considerably higher delay values (LONG DELAY). The LONG
DELAY calculation, however, works only with a minimum distance
of four meters.
If, for example, a speaker is connected with incorrect polarity,
AUTO ALIGN will detect andif POLARITIES is oncorrect this
error automatically.
Use the parameters SHORT DELAY, LONG DELAY and
POLARITIES for the automatic correction of output signals. As
soon as at least one parameter is set to YES, pressing OK will
take you to another sub-menu. If not (all parameters set to NO),
you will be warned that the process cannot be executed.
Fig. 4.12: Setup ß Dly-Corr./Auto-Align
In the AUTO-ALIGN sub-menu you can mute or open all outputs.
Be sure that at least two outputs are open (UNMUTE OUTPUTS
TO ALIGN), otherwise no delay values can be calculated, and a
warning message will be displayed.
Fig. 4.13: Setup ß Dly-Corr./Auto-Align
If at least two or more outputs have been opened and OK has
been pressed, the cursor will jump to ADJUST NOISE LEVEL
and you can hear some test noise. Use the data wheel to adjust
the test noise. The level will be read at the outputs. Press OK to
trigger the measuring process. The DCX2496 calculates the run-
time differences, phase shift and polarity. The OUTs are
automatically adjusted to the optimum delay values calculated.
This process cannot be executed if the test noise level is too low.

4.2.3 COPY
Use the COPY function to copy parameter settings to other
pages. For example, you can transfer the EQ or gain settings
from one channel to another, which saves you a lot of time.
Fig. 4.15: Setup ß Copy
The parameter COPY MODE determines whether only single
pages (PAGE) or the complete channel settings (WHOLE
CHANNEL) will be copied. Select PAGE mode with the PARAM
button and then select the source channel (SOURCE) plus the
SOURCE PAGE to be transferred to another channel. If you select
just one page, the channel to be overwritten (DESTINATION PAGE)
will appear automatically under the parameter DESTINATION.
Please enter the channel to which the data should be copied to
(DESTINATION CHANNEL).
