Pristine Balanced Distribution. Pure Signal Integrity for Multi-Amplifier Systems.

The HAS-3LB-1F-3M is a premium XLR balanced line selector engineered for distributing a single balanced signal to up to three output destinations. Whether you are managing multiple power amplifiers or comparing high-end active monitor speakers, this selector provides the ultimate transparency and reliability required for the finest audio chains.

Key Features

• ■ Precision Balanced Distribution (1 to 3)
  Designed to route one balanced input to one of three balanced outputs. This model switches all three lines—Hot (Pin 2/3), Cold (Pin 3/2), and Ground (Pin 1)—simultaneously, maintaining the electrical integrity of your balanced circuitry.
• ■ SEIDEN Gold-Plated Rotary Switch
  At the heart of the unit is a professional-grade SEIDEN (Japan) rotary switch with gold-plated contacts. It offers exceptionally low contact resistance and a robust mechanical feel, ensuring silent and reliable switching for decades.
• ■ Professional Neutrik Terminals
  Equipped with genuine Neutrik XLR connectors (1 Female input / 3 Male outputs) for secure, low-loss connections. Combined with high-purity Oxygen-Free Copper (OFC) internal wiring, it delivers the shortest possible signal path.
• ■ Superior Japanese Engineering
  Features a 4mm thick solid aluminum front panel and a 40mm solid aluminum machined knob. The rigid chassis provides excellent shielding and stability, standing up to the heaviest high-end balanced cables.

Applications

• Amplifier Selector: Connect 1 balanced pre-amplifier to up to 3 different power amplifiers.
• Speaker Comparison: Switch one source between 3 pairs of active monitor speakers without unplugging cables.
