Blake BLATLA11 Terrestrial Launch Amplifier

Introduction

Product Summary

• The Blake triple-filtered BLATLAll is a compact and powerful multiband launch amplifier designed for distributing terrestrial television signals in residential and commercial applications such as homes, hotels, and student accommodation environments.
• This low noise 2.5dB (Typical) DVB-T/T2 750 launch amplifier complies with the RED2104/53/EU Class l(L).
• It is an energy-efficient (4.5W) device incorporating sophisticated triple-filtering technology to significantly reduce interference from 4G, 5G, and TETRA signals.

Features 6 Benefits

• Compact design and low energy consumption: Ideal for discreet placement and energy efficiency. Optimized for minimal space, while maximizing performance.
• One single input (F-type) is provided for FM/VHF/UHF. The recommended triplexer for this launch amplifier is the 4G, 5G filtered BLACOM31T (available separately)
• Triple Filtering: Eliminates interference from 4G, 5G and TETRA for exceptional signal quality.
• Variable gain control: Optimises signal strength for various cable lengths and signal weaknesses.
• Suitable for digital and analogue signals: Supports traditional and modern digital terrestrial TV signals.
• Powers masthead amplifier: Provides up to l00mA at 12V to power compatible masthead amplifiers such as the BLAMHDllH.
• Dual colour LED indicators: Provides clear visual indication of operational status, green showing normal operation and amber indicating a short circuit or log periodic connected.
• If the LED is amber, the amplifier circuit will continue to function, but no power will be supplied to the masthead amplifier, if in use.
• Consumes low power, making it cost-effective for continuous operation.
• Safe and reliable operation: Complies with the Radio Emissions Directive 2014/53/EU (meets the harmonised standard EN 303 354 for Class l 470-694MHz so no filter is required) and features proper grounding provisions.

Applications

• Distributing terrestrial TV signals in homes, hotels, and student housing.
• Boosting weak TV signals for improved reception.
• Overcoming signal loss due to long cable runs.

Tips

• Follow our advice to fully utilize our products:
• b) Always use the minimum gain required to avoid signal distortion.
• b) Mount the amplifier in a clean, dry, and well-ventilated location as close to the TV aerial as is feasible. Avoid places prone to high humidity, elevated temperatures, or dust accumulation.
• b) Properly ground the amplifier using a minimum 4mm2 earth bonding cable.
• b) Use F-connectors designed for standard “100” type coaxial cable.
• b) Hand-tighten F-connectors to avoid damaging the unit
• b) Utilise the provided screw slots to mount the amplifier securely (screws not supplied)

Safety Instructions

Overall safety instructions

• Ensure your amplifier is safe to use by matching the plug to your local outlet, using surge protection, and regularly inspecting the power cord for damage.
• Keep it in well-ventilated areas, secure all connections, protect it from liquids, and allow for cooling after extended use. Always consult the manual for detailed guidance.
• Power Safety
  • Ensure the amplifier’s plug matches your local outlet type. Never force a plug into an incompatible outlet.
• Ventilation
  • Keep the vents free of dust buildup. Dust can impede airflow and contribute to overheating.
• Connections
  • Ensure all cables, including the power cord, antenna connections, and speaker wires, are securely fastened. Loose connections can cause electrical issues and potential fire hazards.
• Liquids
  • Keep the amplifier away from liquids and moisture. Spills or damp environments can damage the electronics and pose a shock hazard.

Troubleshooting

• My amplifier is not powering on
  • First, verify that it is powered on and receiving the correct input signal level. Adjust the gain control as specified in the user manual.
  • Additionally, confirm that the amplifier is operating within its designated frequency range for best results.
• I have distorted output
  • Reduce or increase the gain control setting on the amplifier. Then check for excessive input signal overloading the amplifier.
• I am experiencing overheating issues
  • If the amplifier feels excessively hot, turn it off and let it cool down completely. Ensure proper ventilation around the amplifier.
