Chapter 3_Installing the DBC-1200 Lite
3.1 Housing mounting
There are two options for mounting the DBC-1200 Lite amplifier:
1. Using integrated side brackets
Integrated side brackets can be used as shown below. The holes are suitable for bolts or screws
with maximum diameter of 6 mm.
2. Rear mounted using integrated screw holes
For mounting directly onto a cabinet back panel, the rear 6 mm bolt holes (M6) can be used with two 6 mm
threaded bolts (see following picture). Ensure when using this method of mounting that the bolt’s threaded part
is no longer than 10 mm in length when protruding through the back board that the amplifier will be mounted onto.
The total length of the bolt to be used is 10mm + back board depth + washer depth. (M6 bolts are not delivered
with the amplifier).

3.2 Installing coaxial (RF ports)
The DBC-1200 Lite amplifier has one input RF port and two non power-passing RF output ports (Port 1 and Port 2).
All RF ports are PG11 threaded and are protected by plastic dust covers which must be removed before installing
the coaxial connectors.
The amplifier can be factory equipped with PG11 to 5/8” adapter rings. Unused ports must be closed with an end plug
or coaxial connector to ensure the DBC is water tight
Technetix double spring technology has the following advantages:
!BeCu spring contact with NiSn plating provides a secure, simple and repeatable installation
!Less sensitive to human error such as incorrect screw torque
!No cold flow (a screw will get loose over time)
!The spring will adjust to temperature changes while maintaining a perfect connection.
Installing the coaxial connectors
1. Cut the connector pins to a length between 28-32 mm (total) as shown on the drawing of the amplifier (Fig. 1).
IMPORTANT: the total pin length = pin length and connector thread length.
2. Push the connector pin firmly in the port hole (Fig. 2). The amplifier is equipped with a double spring contact, so
no screw is needed to fasten the coaxial connector pin.
3. Tighten the connectors into the housing in accordance with the connector manufacturer’s specification.
The recommended torque force for the PG-11-5/8 adapter ring is 15-16 Nm and 11-13 Nm for the coaxial connectors.
Pin length 28-32 mm

3.3 Closing amplifier lid
When closing the amplifier lid please first use a hex key to tighten the four hand bolts lightly in the
following sequence:
Then, using a torque wrench set to a torque value of 6 Nm, go round again in sequence and tighten
to the final torque setting.
Following this sequence ensures:
1. The rubber gasket between the lid and the amplifier housing is sealed correctly, providing a sound, watertight seal
to prevent water ingress.
2. There is a good RF seal between the RF gasket in the lid and the amplifier housing to prevent RF ingress/egress.
3. Good lid to housing contact for the dissipation of amplifier heat is required. The lid acts as a radiator when
it is correctly secured, keeping the amplifier operating temperature down within parameters when installed
as recommended.

3.4 Power supply
The DBC Lite-1200 has the following power supply options:
IMPORTANT: the power supply and fuses are not field replaceable.
3.5 Powering up the amplifier
1. Verify if the voltage present is in accordance with the amplifier specifications and the network design drawing
calculation. Please make sure that the presence of input voltage is in accordance with amplifier specifications and
network design drawing calculation.
2. The output ports should be connected first and the input port last as this will power the amplifier.
3. Connect the earthing/grounding wire (Fig. 3) (in accordance with local electrical installation regulations)
on the right-hand side of the housing. The maximum diameter of the grounding wire is 3.8mm.
4. Remove the AUX DS 0 dB attenuator temporarily to protect the amplifier from eventual high input RF levels.
The attenuator can be re-installed once the electronic input and interstage attenuator have been configured to
10 dB or more (as a starting point).
5. Switch on the power and check that the status LED is steady green when power is present.

Output splitter selector
Referring to the network design documentation, configure the output splitter by installing a 0 pad/attenuator into
the last three of five holes on the right-hand side (to pass all RF into port 1) or the first three holes on the left-hand
side (to pass all RF into port 2). Alternatively, install a relevant 2-way splitter or directional coupler.
Diplexer and diplexer upgrade
Referring to the network design documentation, verify that the diplexer has the correct band split.
Make sure that the output diplexer (right diplexer) has metal screening installed.
Output diplex shielding is required to meet the specified flatness specifications up to 1.2 GHz.
In the initial production of the DBC-1200 Lite the RF shield is glued to the diplexer. In later batches the shield
is held in place by a plastic clip.
The glued diplexer can be removed in the field and re-used on a standard diplexer for a future diplex upgrade.
(Removal of a glued diplexer is described in a separate document).

IMPORTANT: If the output RF levels are above 109 dBµV level
do not switch to low power mode as this will result
in BER and poor MER.
Hybrid in low power mode :
The maximum RF output level loaded with 120 QAM channels 8 MHz
is 109 dBµV (49 dBmV) with 9 dB tilt
IMPORTANT: When output RF levels are below 109 dBµV level
you may switch to low power mode as this will
result in lower power consumption (2-3 watts less
power usage.

1. Complete the diplexer type and end frequency
Amplifier template should be set to: Free (Fig. 10). The amplifier name field is not supported for the DBC-1200 Lite.
To prevent overdriving the RF amplifier, select 10 dB for the pre and interstage attenuator and EQ settings to 0 dB
(Fig. 11).
Once these values are set in the application, click on send to amp to set these values electronically.
Re-install the AUX-Ds 0 dB attenuator, the amplifier input will now be protected by the 10 dB attenuators.

Fig. 13
Fig. 12

2. Configuring downstream
In the example below the RF output level is 111 dBµV with 9 dB tilt.
Connect the field meter to the output directional -20 dB test point and verify the input tilt. With the pre-stage
equaliser set the RF output level to flat.
Read the RF channel level (+ 20 dB from test point)
For example: RF output port reading is 108 dBµV
The calculated input RF port level is: 108dBµV - 44 dB (gain) +10dB (pre-stage)+10 dB (interstage) = 84dBµV
The input level at the first amplifier stage should be 72 dBµV
Pre-stage attenuator should be set to: 84-72dBµV= 12 dB
Adjust interstage EQ end interstage attenuator to obtain the desired RF output port level (Fig. 12).
3. Configuring upstream
Alignment with return path sweep set up equipment:
The return path gain of the amplifier is 25 dB (with 0 dB attenuator settings)
Set the return path sweep generator output to the required return path / upstream alignment level plus 20 dB to
overcome the test point insertion losses.
Finally, adjust the amplifier upstream tilt and the attenuation in the BLL software (Fig. 13) to obtain a flat sweep
response at the correct level for the upstream network design.
