Explanation of graphical symbols

The lightning symbol within a triangle is intended to alert
the user to the presence of uninsulated "dangerous
voltages" within the unit’s chassis that may be of
sufficient magnitude to constitute a risk of electric shock
to humans.

The exclamation point within a triangle is intended to
alert the user to the presence of important operating and
service instructions in the literature accompanying the
product.

Before using this product, carefully read the
applicable items of the following safety instructions.

1. Keep these instructions for future reference.

2. Read these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Keep water or other liquids away from the unit. Do not place
liquid filled containers, for example beverages, on top of the
unit.

6. Do not operate the unit while it is wet or standing in liquid.

7. Always operate the unit with the chassis ground wire
connected to the electrical safety earth. Do not defeat the
safety purpose of a grounding-type plug. A grounding-type
plug has two blades and a third grounding prong. The third
prong is provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for replacement of
the obsolete outlet.

8. Do not use this unit if the power cord is damaged or frayed.
Protect the power cord from being walked upon or pinched,
particularly at the plugs and the point where it exits from the
apparatus.

9. The unit is intended for use in a 19" rack. Follow the mounting
instructions. When a rack on wheels is used, exercise caution
when moving the loaded rack to avoid injury from tipping
over.

10. Unplug this apparatus during lightning storms or when unused
for long periods of time.

11. Lay all cables connected to the unit carefully so that they
cannot be crushed by vehicles or other equipment and that no
one can either step on them or trip over them.

12. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way
such as:
– Power-supply cord or plug is damaged.
– Liquid has been spilled into the unit.
– An object has fallen into the unit.
– The unit has been exposed to rain or moisture.
– The unit does not operate normally.
– The unit was dropped or the chassis is damaged.
– Do not remove top or bottom covers. Removal of the covers

will expose hazardous voltages. There are no user
serviceable parts inside and removal may void the warranty.

13. Use the mains plug as the disconnecting device and keep it
readily accessible. If the mains plug is not readily accessible
due to mounting in a 19" rack, then the mains plug for the
entire rack must be readily accessible.

14. An experienced user must always supervise the equipment,
especially if inexperienced adults or minors are using the
equipment.

The d&b DS20 is a 16 output channel break-out box connecting
the Milan audio network to the AES3 digital audio standard.

In addition, 4 x AES3 input channels are provided for use as a
simple break-in box, e.g. at Front of House.

Configuration and control of the device is performed using the

from one single software platform. You can find download
information for this (free) software at

www.dbaudio.com.

The DS20 is mainly intended for use within the d&b Touring rack
assemblies.

NOTICE!

Acoustic interference and malfunctions may occur if the unit is
operated in the immediate vicinity of high-frequency transmitters
(e.g. wireless microphones, mobile phones, etc.). Damage to the
device is unlikely, but cannot be excluded.

Before starting up the device, please verify the shipment for
completeness and proper condition of the items.

If there is any sign of obvious damage to the unit and/or the
