MODEL: DCF-1
Zinwell Digital Channel Filter
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).

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.

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.
Antenna Power

Antenna Power
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.

However, before starting to configure, set your country first in order to load the frequency plan accordingly (see 3.2.3 Set Country).
- Page 2 NOTE: Due to automatic LTE filter selection capability of DCF-1, each input port can receive VHF or UHF band signal only. To program it, the user needs to choose an input port and associate a channel to it, and DCF-1 will automatically lock to VHF/UHF band based on the command. In above case, the user has chosen CH28 and that will lock RF-IN1 to receive UHF band signal only.
- Page 3 Output power level can be adjusted from 93 dBμV ~ 113 dBμV Slope rate can be changed from 0 ~ -9 dB The Output Level is for the total channel power, the more channels are added to the DCF-1, the lesser output power you should give to each channel.
