Fracarro 4-SAT Amplifier with A.B.L.A. Model: AMP435SA ABLA (271173) Satellite Booster 4 Input Auto Signal Adjust, Gain 16-36 dB, Fixed Slope 6dB for SMATV & L-Band Medium to Large Satellite Systems

Product Overview:
Revolutionize and seamlessly stabilize your building's SMATV satellite distribution system with the FRACARRO AMP435SA ABLA (Code: 271173). This professional-grade head amplifier features intelligent A.B.L.A. (Automatic Building Level Adjustment) technology, acting as a smart signal guardian that automatically adjusts and maintains a constant output level even when input signals fluctuate. Supporting 4 satellite inputs and delivering a high output level of up to 121dBμV with built-in overload protection, it is the ultimate, high-efficiency solution for MATV/SMATV systems in medium to large buildings, as well as long-distance wiring between multiswitches. It ensures every room enjoys crystal-clear, uninterrupted entertainment.

Key Features & Specifications:
- A.B.L.A. (Automatic Building Level Adjustment) Technology: This standout, proprietary technology automatically keeps the output level constant at your predefined setting, regardless of any fluctuations or changes in the input signal strength.
- Smart LED Status Indicators: Dedicated A.B.L.A. LEDs light up when the automatic output adjustment is operating correctly. If the input signal drops too low, the LED goes out, and the device smoothly transitions into a standard fixed-gain satellite amplifier (36dB).
- High Performance & Isolation: It features 4 SAT inputs and 4 SAT outputs across a 950-2150 MHz bandwidth. Delivering a powerful maximum output level of up to 121dBμV and an excellent port-to-port isolation (≥35dB), it effectively minimizes inter-port interference.
- Flexible & Secure Powering Options: The unit can be remotely powered via the Satellite lines 1 (VL), 2 (HL), and 3 (VH), or directly via the side DC connector. It includes a current overload protection system and allows power direction control via a side-mounted dip switch.
- Easy Installation: Designed for effortless setup, it comes equipped with new adjustment trimmers and standard, color-coded inputs for clear identification. An external power supply unit, PSU1430F (14V, 3A), is also included in the package.

Applications:
Thanks to its powerful amplification and automatic level-stabilization capabilities, this model is perfectly suited for:
- Medium to Large Scale MATV / SMATV Systems: Ideal for condominiums, hotels, apartments, or office buildings where satellite signals must be distributed across a large number of rooms.
- Long-Distance Connections Between Multiswitches: Perfect for multi-switch networks covering long physical distances where cable loss is inevitable. This amplifier boosts and equalizes the signal to maintain consistent strength across the entire network.
- Environments with Unstable Source Signals: In areas where satellite dish signals fluctuate due to weather conditions or interference, the A.B.L.A. system ensures that end-user devices (such as satellite set-top boxes in each room) receive a rock-solid, high-quality signal—eliminating screen flickering and signal loss.
