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. 7472L1 – 7472L2)
  • Optional: Power Supply 12V (ref. 2437)

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

How Autoscan works:

• Plug-in Power Supply.
• The 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 error during the scan. Unpowered and repower within 6 seconds to restart the auto scan.
• WARNING: do not turn off the power during SCAN.

How to reprogram or force channel scan

• When a power outage causes missing channels on your TV, a reset is needed
• Reset: pull out the power supply and put it back in within 6 seconds
• The status LED will blink when re-scanning
• If a power interruption lasts longer than 6 seconds, there is no channel scan and the initial settings are kept
• Important note for installers! Do not cut the power plug and insert the power supply directly into a power cabinet/power strip. Make sure the end-user or installer can easily and safely unpower and repower the device.

LTE Filtering
LTE1 = LTE800 = 4G (REF. 7472L1) Everything above 790MHz is filtered out :

LTE2 = LTE700 = 5G (REF. 7472L2) Everything above 694MHz is filtered out :

Duplicate channel switch OFF:

Weakest channel is rejected. See example below:

• CH30 > CH30
  • ➔ CH30 is transmitted
  • ➔ CH30 is rejected
• CH40 < CH40
  • ➔ CH40 is rejected
  • ➔ CH40 is transmitted

Duplicate channel switch ON:

Weakest channel is converted to LTE band. See example below:;

• CH30 > CH30
  • ➔ CH30 is transmitted
  • ➔ CH30 is converted to LTE band
• CH40 < CH40
  • ➔ CH40 is converted to LTE band
  • ➔ CH40 is transmitted

SAFETY INSTRUCTIONS

To prevent fire, short circuit or shock hazard:

• • Do not expose the unit to rain or moisture.
  • Install the unit in a dry location without infiltration or condensation of water.
  • Do not expose it to dripping or splashing.
  • Do not place objects filled with liquids, such as vases, on the apparatus.
  • If any liquid should accidentally fall into the cabinet, disconnect the power plug.

To avoid any risk of overheating:

• • Install the unit in a well-aired location and keep a minimum distance of 15 cm around the apparatus for sufficient ventilation
