4.2 Amplifier

GB
Connect the power amplifiers or units for further
signal processing to the XLR connections OUT-
PUTS (22).

4.3 Computer

For remote control of the DSM-260 via a com-
puter, connect the computer via a USB cable to
the jack (17).
Alternatively, the unit may be controlled via
the RS-485 interface. Connect the RS-485 out-
put of the computer to the jack RS-485 IN (19);
the contact configuration is shown in figure 2.
The output jack RS-485 OUT (18) may be con-
nected to the jack RS-485 IN of another DSM-
260 in each case. Thus, up to 32 units to be con-
trolled may be connected in a chain.
If several units are connected and longer
control lines are used, the control output of the
last unit of the chain should be provided with a
terminating resistor (120 Ω resistor between pins
2 and 3 of the connection) to prevent interfer-
ence during signal transmission.

4.4 Mains connection

Connect the supplied mains cable to the mains
jack (14) and the mains plug to a socket (230 V~/
50 Hz).

5 Operation

5.1 Switching on / off

Prior to switching on the connected power ampli-
fiers, connect the DSM-260 with the POWER
switch (13). The adjustments of the last opera-
tion are loaded and the name of the last configu-
ration loaded from the memory is shown.
CAUTION The DSM-260 offers very flexible
possibilities of configuration. For
example, an output configured for
controlling a tweeter may become
the bass frequency output in
another configuration.
To prevent any overload of the speakers, prior to
switching on the power amplifiers, always check
if the configuration loaded of the DSM-260 cor-
responds to the speaker constellation con-
nected.
After use, switch off the unit with the POWER
switch. All adjustments will be maintained.

5.2 Basic setting (System Utilities)

The DSM-260 is adjusted via a menu in the dis-
play (1). The menu is called for the general sys-
tem settings with the button UTILITY (6), the
menus for the adjustment of the inputs and out-
puts are called by the selection of the input or
output with the corresponding button (10). To
navigate through the menu and to change the
adjustments, use the buttons ENTER (4), ESC
(5) and the rotary knob NAV/ PM1 (2). A menu
item can be selected with the rotary knob. The
button ENTER calls the submenu or confirms an
input while the button ESC returns to the higher
menu level without accepting a change. To
change parameters, the two rotary knobs PM2
(3) and PM3 (7) are available in addition. If the
*
display shows behind an option, this corre-
sponds to the present adjustment.
An overview of the menu "UTILITY" is shown
in figure 3 on page 3.

5.2.1 Model configuration

To create a new configuration for which no
model has been stored as a "Program"
( chapter 5.5.1), it is possible to revert to the
following three model configurations:

Changing Xover
The outputs are now assigned to the inputs
and named corresponding to the model con-
figuration. All parameters are reset to stan-
dard values (amplification of input and output
set to 0 dB, filters deactivated, the points of
activation of compressor and limiter at the
highest values, the delay times set to 0, nor-
mal phase). As a precaution, the outputs are
muted for the time being and have to be
switched on individually and manually.
5) To exit the menu, press the button ESC (5)
twice. It is also possible to directly change to
the adjustment of an input or output with one
of the buttons (10).
Important: When selecting a model configura-
tion, only the names of the outputs and the
assignment of the outputs to the inputs are pre-
set. For using the DSM-260 as a crossover net-
work, always adapt the filters to the speakers
used prior to the application (
as the operation of a speaker outside its fre-
quency range may lead to distortions and over-
load of the speaker.

5.2.2 Selecting a signal source

The unit has inputs for analogue (23) and digital
(20) signals which may be used alternatively.

5.2.4 Unit for signal delay

The signals of all inputs and outputs can individ-
ually be delayed. This is e. g. useful if speakers
are placed at different distances from the listen-
ers. To balance the delay time of the sound, the
signal of the speaker located nearby is delayed
so that it does not reach the listener earlier than
the signal of the speaker located far away.
To spare the user the trouble of calculating
the delay time of the sound, the delay can alter-
natively be entered not only as a time indication
but also as a distance. The device calculates
with a sound speed of 340 m / s.
