Fracarro 4-SAT Line Amplifier with A.B.L.A. Model: SWA435SSA ABLA (271172) Satellite Booster 4 Input Auto Signal Adjust, Gain 16-36 dB, for SMATV & L-Band Medium to Large Satellite Systems

Product Overview:
Seamlessly elevate and stabilize your building's SMATV satellite distribution system with the FRACARRO SWA435SSA ABLA (Code: 271172). This professional-grade line amplifier integrates intelligent A.B.L.A. (Automatic Building Level Adjustment) technology to automatically control both signal strength and slope levels, maintaining a constant output even when input signals fluctuate. Supporting 4 satellite inputs and delivering a high output level of up to $121\text{dB}\mu\text{V}$ with built-in overload protection, it offers the most efficient solution for MATV/SMATV systems in medium-to-large buildings or long-distance wiring between multiswitches. This ensures every viewing point receives a crystal-clear, stable, and uninterrupted signal. (Note: As a line amplifier, the external power supply PSU1830 is not included in the package).

Key Features & Specifications:
- Dual Intelligent A.B.L.A. Technology: Supports independent adjustment of both output level and slope for each satellite input, allowing the device to maintain your predefined output level at all times despite input signal fluctuations.
- Smart LED Status Indicators: Dedicated A.B.L.A. LEDs light up when the automatic output signal adjustment is operating properly. If the input level drops too low, the LED goes out, and the unit automatically switches to operate as a standard fixed-gain satellite amplifier (36dB).
- High-Level SAT Tilt Adjustment: Provides up to 15dB of satellite tilt adjustment to effectively compensate for high-frequency signal losses caused by long cable runs.
- Excellent Performance & Isolation: Features 4 SAT inputs and 4 SAT outputs across the 950-2150 MHz bandwidth. It delivers a maximum output level of up to 121dBuV and achieves an outstanding port-to-port isolation (SAT-SAT Isolation > 35dB) to minimize cross-channel interference.
- Flexible & Secure Powering Options: Supports remote power delivery through satellite lines 1 (VL), 2 (HL), and 3 (VH), or direct connection via the side DC connector. Voltage passage is managed via a side DIP switch, and the unit features a double power supply port for enhanced system robustness along with current overload protection.
- Easy Installation: Equipped with new adjustment trimmers and standard, color-coded inputs for straightforward setup. The compact product dimensions make it easy to fit into existing distribution lines.

Applications:
Thanks to its automatic line amplification and slope compensation capabilities, this model is perfectly suited for:

- Medium to Large Scale MATV / SMATV Systems: Ideal for installation in condominiums, hotels, apartments, or office buildings where satellite signals need to be distributed across a large network of backbone cabling to multiple floors and rooms.
- Long-Distance Connections Between Multiswitches: Perfect for multi-switch networks covering extensive cable distances where "signal attenuation" and "high frequencies fading faster than low frequencies" (Cable Loss & Slope) occur. This unit acts as a line amplifier to boost, adjust tilt, and stabilize the signal to maintain uniform strength across the entire network trunk.
- Environments with Unstable or Dropping Signals: In areas where weather conditions or extensive coaxial line drops cause signal strength to fluctuate, the A.B.L.A. technology locks the output signal constant. This ensures that end-user satellite boxes operate smoothly without screen stuttering or signal loss.
