10. Link mode / content of link channels
Here you can appoint, which audio signal is on the link A + B (adjustable for each
channel). If you choose the menu item „source“ the input signal is also on the link socket
available, that means input signal = output signal (independent if there is an analogue or
digital input signal). If you
do not
choose the menu item „source“, you will get always a
digital link signal on the link socket (all link-possibilities for channel A + B are listed
below).
The link of channel C + D can always reproduce the input signal of these channels
(always analogue), that means input signal = output signal.
Digital link-signal
Display shows:
A and C (digital stereo out - of A+C)
or
d1
A:C/d1
B and D (digital stereo out - of B+D)
or
d2 B:D/d2
A+B (digital mono out - sum. of A+B)
or
d1 mono A+B/d1 mono
C+D (digital mono out - sum. of C+D)
or
d2 mono C+D/ d2 mono
C+D always (digital stereo out - of C+D)

A+B+C+D
Example 1:
You will drive an actively or a passively channelled PA system with your DA 428 (the stereo input
signal is analogue and the subwoofers are driven mono). Please plug in the left input signal to
input A and the right input signal to input B of DA 428.
On input C + D you will connect the analogue stereo-signal of group 1+2 from the mixing desk
e.g. for a digital recorder.
After adjust the „input mode“ (see page 11), please set the following „link mode“ for link A:
link A = C+D always – works as AD-converter (analogue-stereo in, digital-stereo out)
Example 2:
You will drive 12 passively channelled PANO Line Array elements with two DA 428 (the stereo
input signal is analogue). Additionally you need a center-cluster because your audience area is
very width. This center-cluster consists also of 4 PANO Line Array elements. Please plug in the
left input signal to input A and the right input signal to input B of the first DA 428. Now you have to
route output A – output C of the first DA 428 to „A/d1(L)“ = left audio signal for the left 6 elements
(connect always two together). Out D you have to rout to „A+B/d1(L+R)“ = sum. Of channel A+B.
With this signal you can drive the both upper elements of the center-cluster.
After this, please set the following „link mode“ for link A + B of the first DA 428:
Link A = A+B/d1 mono – the left + right analogue audio signal will be sum. and digitalized
link A (analogue-stereo in, digital mono out);
for both lower elements of the center-cluster of the second
DA 428 on output D
Link B = source – the right audio signal will be linked (analogue in, analogue out);
for the right 6 elements of the second DA 428 on output A - output C
