9. Routing of input channels
Here you can set the routing for each input channel. This process depends on the input
signal (analogue or digital). That means, if you have chosen the input mode „digital“
(corresponds only for channel A, because this input channel can operate with a digital
audio signal, too; see page 14), the routing possibilities will be automatically switched to
digital (see table).
In the following table you will find all adjustable configurations (per channel), which can
be chosen.
Input signal
Display shows:
analogue or digital
A
or
d1(L) A/d1(L)
B
or
d1(R) B/d1(R)
B always (always analogue)
B
always
A+B
or
d1(L+R) A+B/d1(L+R)
Example 1:
You will drive an actively channelled PA system with your two DA 230 (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 the first DA 230. Now you can link the input signals digitally to
the second DA 230 (link mode for channel A of the first DA 230: A:B/d1).
Adjust the „input mode“ for channel A of the first DA 230 to „analog“ or “auto detection”
(see page 14). After this, please select the following routing of the first DA 230 (amplifier for the
subwoofer):
Out A = A+B/d1(L+R) – left subwoofer (mono signal: sum A+B = -6dB)
Out B = A+B/d1(L+R) – right subwoofer (mono signal: sum A+B = -6dB)
Adjust the „input mode“ for channel A of the second DA 230 to „digital“ or “auto detection”
(see page 14). After this, please choose the following routing of the second DA 230 (amplifier for
the top units):
Out A = A/d1(L) – left top unit(s)
Out B = B/d1(R) – right top unit(s)
Example 2:
You will control an actively channelled bass array with your two DA 230 (using a digital input
signal). Please plug in the digital input signal to input A of the first DA 230. Now you can link the
input signal digitally to the second DA 230 (link mode for channel A of the first DA 230: source).
Adjust the „input mode“ for channel A for both amplifiers to „digital“ or “auto detection”
(see page 14). After this, please select the following routing for both DA 230:
Out A = A+B/d1(L+R) – left subwoofer (mono signal: sum A+B = -6dB)
Out B = A+B/d1(L+R) – right subwoofer (mono signal: sum A+B = -6dB)
