INTRODUCTION
Product description
- Scans all channels, amplifies the weak signals while keeping the strong channels
- All output channels have an equal and stable output power
- Treats even the most difficult situations with adjacent channels
- Channels with the same frequency can be amplified in and re-located to the LTE band (switchable)
- Fully automatic channel scan and process function upon double power start-up.
- Fully automatic recognition of the applied country channel plan
- SAW filters for LTE (4G or 5G) protection on all inputs
- Outdoor weatherproof mast-head housing
- DC Power over coax
- All ports ESD protected
Package contents
- 1 Smart Amp (ref. 7473L1 – 7473L2 – 7474L1 – 7474L2)
- 1 Power Supply 12V (ref. 2437)
- 1 wall clamp

HARDWARE INSTALLATION
Installing the Smart Amp
- Connect your Terrestrial antennas to the Smart Amp*
- Connect the Smart Amp output to the Power Supply
- Connect your TVs to the Power Supply
Important: Mount the module vertically to a wall in a well-ventilated room and leave a minimum space of 15 cm around the product to guarantee maximum ventilation of the product
- The Smart Amp does not allow pass-through DC-power for pre-amplifiers or active antennas
Duplicate channel switch OFF:
The weakest channel is rejected. See the example below:
CH30 > CH30
CH40 < CH40
➔ CH30 is transmitted
➔ CH30 is rejected
➔ CH40 is rejected
➔ CH40 is transmitted
Duplicate channel switch ON:
The weakest channel is converted to LTE band. See the example below:;
CH30 > CH30
CH40 < CH40
➔ CH30 is transmitted
➔ CH30 is converted to LTE band
➔ CH40 is converted to LTE band
➔ CH40 is transmitted
LTE Filtering
LTE1 = LTE800 = 4G (REF. 7473L1 & 7474L1) Everything above 790MHz is filtered out:
LTE2 = LTE700 = 5G (REF. 7473L2 & 7474L2) Everything above 694MHz is filtered out:
How Autoscan works:
- Plug-in Power Supply
- Status LED will blink green when scanning
- Status LED solid green when auto scan ready (This can take up to 20 seconds)
- Status LED red when an error during the scan. Unpowered and repower within 6 seconds to restart auto scan
- WARNING: do not turn off the power during SCAN
How to force channel scan:
(FORCE CHANNEL SCAN = RESET = REPROGRAM)
- Unpowered and Repower within 6 sec (Status LED will blink when scanning)
- If power interruption (>6 sec) = no reprogram = settings are kept
