The 1U rack-mounted 4-channel passive isolated microphone splitter is designed for broadcast applications, distributing and isolating microphone-level signals between broadcast vehicles and remote equipment. Each input channel on the MLTSP1X3 provides one direct output plus two transformer-isolated outputs.

Every isolated output features a front-panel ground lift switch. Input connectors (XLR female) are located on the front panel, while output connectors (XLR male) are positioned on the rear panel. The interface includes a positive locking mechanism to prevent accidental cable disconnection.
