DigitalBooster DB-4
The DigitalBooster DB-4 is a short-circuit protected
Power-Amplifier (Booster) for digital Model Railway
Layouts from the Digital-Professional-Series!
The DB-4 amplifies the digital formats of Märklin-
Motorola, mfx®, M4 and DCC.
DB-4-G Part-No.: 080073
>> finished module in a case <<
The DigitalBooster DB
-
4 provides a
maximum digital current of 2.5 or 4.5
Ampere and amplifies the digital
formats of Märklin-Motorola, mfx
®
,M4
and DCC.
The DB-4 can operate with several
digital command stations by using the
5-poles booster bus, the CDE booster
bus or the Roco-booster bus.
The DigitalBooster DB-4 receives the
power supply not from a classical
model railway transformer but from
the switched mode mains power
supply DB-4 PowerSupply. On this
unit is the stabilized digital track
voltage adjustable between 15 and 24
Volt, suitable for all track gauges.
This product is not a toy! Not suitable for children under 14 years. Improper use will imply danger or injuries due to
sharp edges and tips! Please store this instruction carefully.

2. DB-4 connection to the Digital-Command-Station or to other
Booster:
The galvanic separated boosterbus connections enables the application of the
DigitalBooster DB-4 in connection with several command stations by using the
5-poles Boosterbus, the CDE-Boosterbus or the Roco-Boosterbus.
The DB-4 is no Booster-Adapter. A change of the bus-system is impossible. The
booster-bus used for the connection of the first DB-4 to the digital command station
has to be used furthermore.
The below table indicates the possible connections to the available command
station.

2.1. DB-4 connection via the 5-poles Boosterbus:
The DigitalBooster DB-4 can be connected by use of the 5-poles boosterbus cable
(order code: Kabel Booster 1m, Part-No.: 000123), to one of the command stations as
per above table or to other boosters (e.g. DB-4, DB-2, 6015, 6017, Power 2, Power 3).
The first booster shall be always connected to the command station by use of a 5-poles
boosterbus cable. The second booster shall be connected to the first one and so on.

DigitalBooster DB-4 – Manual
- 4 -
Please connect a plug of the 5-poles boosterbus cable onto the command station or to
the previous booster. The connection of the plug is correct at the Control Unit,
Intellibox, TWIN-CENTER, Märklin Booster 6017, Power 2 and Power 3 if the direction
of the cable shows to the bottom. For the Märklin Booster 6015 is the correct position
of the Boosterbus-Cable showing to the top.
The second plug of the boosterbus cable has to be connected at the DigitalBooster DB-
4to the pin bar ST1 with the marking “IN”.
Please attend that the white single wire of the 5-poles cable corresponds to the white
marking at the pin bar ST1.
The plug position of the 5-poles boosterbus cable is correct on the DigitalBooster
DB-4 if the twisted cable has a direction away from the booster.
If a following booster shall be connected with a 5-poles boosterbus cable to the
DigitalBooster DB-4 this has to be done via the pin bar ST2 (“OUT”).

3. DB-4 connection to the Switched Mode Mains Power Supply DB-4-
PowerSupply:
The DigitalBooster DB-4 shall not get the power supply over the socket BU1 from a
classical model railway transformer but from the Switched Mode Mains Power Supply
DB-4-PowerSupply.
The DigitalBooster DB-4 has been matched to the Switched Mode Mains Power
Supply DB-4-PowerSupply and should be operated only together with this particular
unit.
At first adjust the voltage selection switch of the DB-4-PowerSupply to a voltage
between 15 and 24 Volt. This voltage is corresponding to the digital voltage of the
DigitalBooster DB-4 for the supply to the rails.

DigitalBooster DB-4 – Manual
- 7 -
If there are several output plugs supplied with the Switched Mode Mains Power
Supply DB-4-PowerSupply please select the plug 5.5X2.1. This plug has an outside
diameter of 5.5mm and a bore diameter of 2.1mm. The outside pole is negative and
the inner pole is positive.
Please attend as well to the instruction supplied together with the DB-4-PowerSupply.
4. DB-4 connection to an Own Track Section:
The DigitalBooster DB-4 is a power amplifier for your digital model railway layout.
The digital current of the DigitalBooster DB-4 is available at the clamp KL1 next to
the two light emitting diodes.
The DB-4 supplies digital current to the own track section via this clamp. This section
has to be electrical separated from the adjoining track sections because those
receive their supply from the digital command station with integrated booster or from
further booster.
4.1. 3-Conductor Track System:
If the manufacturer of your digital command station permits a common layout ground
(“brown”) the center conductor of the 3-conductor track has to be isolated at the
cross over joints from one to the next booster electrical circuit. The isolated center
conductor gets the supply from the connection “red” of the clamp KL1 of the
DigitalBooster DB-4.

If the manufacturer of the digital command station does not permit a common layout
ground (“brown”) it is required additionally to isolate the rails at the cross over joints.
If the manufacturer of the digital command station stipulates mandatory the installation
of a rocker switch at the cross sections of the center conductor this switch has to be
installed.
Alternative is it possible to use our Booster Keep Separate Module BTM-SG for the
cross over joints. This module separates electrically definite the booster sections
without rocker switch and provides the possibility to drive at slow speed at the cross
over sections.
