Setup
Before turning on the R&S DDF205, please make sure that the following con-
ditions are fulfilled:
●Covers are in place and all fasteners are tightened.
●Fan openings are unobstructed.
●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are correctly connected and not overloaded.
●The R&S DDF205 is dry and shows no condensation.
Non-observance may cause damage to the R&S DDF205 or other devices in
the setup.
The R&S DDF205 is supplied completely assembled except for the handles and
mounting brackets, which must be attached by the user.
1.2 Setup
1.2.1 Bench Operation
Equipment cooling
Do not expose the R&S DDF205 to humidity. Leave at least 50 mm of empty
space along both side panels in order to ensure proper equipment cooling.
There are no special requirements for desktop use. To facilitate access to the front
panel elements, you should raise the front of the R&S DDF205 by folding out its
standing feet.

Risk of injury
The feet may fold in if they are not folded out completely or if the R&S DDF205
is shifted. The feet may break if they are overloaded. Fold the feet completely
in or completely out to ensure stability of the R&S DDF205 and personal
safety. To avoid injuries, never shift the R&S DDF205 when its feet are folded
out. The overall load (the R&S DDF205's own weight plus that of any devices
stacked on top of it) on the folded-out feet must not exceed 500 N. Place the
R&S DDF205 on a stable surface. Secure any devices stacked on top of it
against slipping (e.g. by locking their feet on the top front frame). When the
R&S DDF205 is standing on its folded-out feet, do not work under it and do
not put anything under it as this would pose a risk of personal injury or material
damage.
The R&S DDF205 can be used in any of the positions shown here.

1.2.2 Rack Mounting
Ambient temperature
The R&S DDF205 should be used in an area where the ambient temperature
does not exceed –10 °C to +55 °C (DDF205 without front control panel) or
0 °C to 55 °C (DDF205 with front control panel), respectively. The
R&S DDF205 is fan-cooled and must be installed with sufficient space along
the sides to ensure a free flow of air. Make sure that there is sufficient space
for hot air to escape from the R&S DDF205. To ensure sufficient cooling do
not attach telescopic rails to the sides of the unit.
1.2.3 In-vehicle Mounting
For use in vehicles, the R&S DDF205 can be powered directly from the vehicle's
battery via the DC input.
1.2.4 EMI Protective Measures
In order to avoid electromagnetic interference (EMI), the R&S DDF205 may only be
operated when it is closed and all shielding covers are in place. Use only appropriate
shielded signal and control cables with proper termination.
1.2.5 Connecting the R&S DDF205 to the Power Supply
Connect the R&S DDF205 observing the following sections and instructions for use.
The R&S DDF205 is suitable only for DC operation.
1.2.5.1 Connecting to the Power Adapter
The R&S DDF205 is connected to the AC supply 100 V to 240 V via an external
AC/DC power adapter and to the socket X1 (10 VDC to 32 VDC) on the rear panel.
Recommended connector: Neutrik® Speakon® NL4FX (see the figure below).

Installing the connector:
1. Insert the Speakon® NL4FX connector into socket X1 on the rear panel.
2. Turn the connector clockwise until it is locked in place and secured by the safety
latch.
Removing the connector:
1. Press and chuck back the safety latch of the Speakon® NL4FX connector.
2. Turn the connector counterclockwise and withdraw it.

1.2.5.2 Connecting to the DC Source
The R&S DDF205 is connected to an external 10 VDC to 32 VDC source (e.g.
battery) via connector X1 on the rear panel. Recommended connector: Neutrik®
Speakon® NL4FX, see chapter 1.2.5.1, "Connecting to the Power Adapter",
on page 8.
DC supply voltage
Make sure that the available supply voltage is between 10 V and 32 V.
Observe correct voltage polarity when connecting. Incorrect polarity may blow
the fuse on the DC converter inside the R&S DDF205 or damage the
R&S DDF205.

1.2.6 Power On and Off
The DC power connection X1 is located at the top left corner of the
R&S DDF205 rear panel. With the DC power connected, the
R&S DDF205 is in STANDBY or READY state, depending on the
state of the STANDBY toggle switch at the front panel of the
R&S DDF205 when it was last switched off. The standby power is
below 0.8 W.
1.2.7 STANDBY and READY
The STANDBY key is located at the bottom left corner of the front
panel. With the DC power connected, press the STANDBY key
briefly to switch the R&S DDF205 from the STANDBY to the READY
state and vice versa. In STANDBY state, the amber LED on the right
will turn on and only the power switch circuit is being powered. In this state, it is safe
to remove the DC power and disconnect the R&S DDF205 from the AC/DC power
adapter. In READY state, the green LED on the left is on. The R&S DDF205 is ready
for operation. All modules are being powered and the R&S DDF205 initiates its
startup procedure.
DDF205 without front control panel
In the case of DDF205 without front control panel, the green Power LED dou-
bles as a 'Fail' status LED. In conditions of failure, the LED will turn red instead
of green, as shown in the figures below.
