CONFIGURATION
DCF-1 uses LCD panel as the interface to change the settings and configuration. User can easily modify the parameters by using the buttons on
DCF-1 without any other devices. However, before starting to configure, set your country first in order to load the frequency plan accordingly
(see 3.2.3 Set Country).

Setting Instruction:
3.2.1 Input (Configuration Introduction)
DCF-1 is suitable for collective antenna application with its own booster, filter, combiner, channel converter, equalizer, and amplifier. Moreover,
there are 4 VHF/UHF inputs and 1 FM input in this device to receive different terrestrial TV/FM signals.
Pre-Amplifier
Under the level of each inputs (RF-IN1 to RF-IN4), user can choose to turn on/off the amplifier.
The pre-amplifier option increases the signal power, but it also increases the system noise and may degrade the signal quality. Misusing pre-
amplifier could significantly increase distortion and consequently reduce the signal quality in the output. Therefore, it is recommended to know
the signal quality on the input side (gain, tilt, bandwidth and noise figure) when applying pre-amplifier to measure its impact on the output side.
Recommendation: Turn on the Pre-Amplifier only when the input signal level is too low (Lower than 60 dBμV). The user may refer
to the automatic input signal power level measurement when adding a channel on DCF-1.
NOTE:
If target channel’s signal level is low but other high level channels in the same band could saturate Pre-Amplifier and cause poor signal quality. Refer to
all receiving channels quality to decide whether to turn on pre-amplifier or not.

Each input port (RF-IN1 to RF-IN4) is capable of supplying 12V, 100mA (max.) to an active antenna. The user may choose to turn on/off the
power on each input port based on the nature of the antenna (passive or active) of user’s choice.
