Interconnect your 2- and 4-wire intercom systems with this 2/4 Wire Converter from Hollyland. The converter features 3-pin XLR inputs for 2-wire or 4-wire intercom systems such as ALTAIR, ClearCom, Hanson, Syscom and Datavideo, and it is powered using the intercom system over a 12 to 36V 2-wire connector. Other features include voltage and static protection, electrostatic discharge (ESD) testing to avoid damage, and distance compensation switches that support cable lengths up to 656′. The unit measures 1/4 RU and can be daisy-chained with up to three other units to create an environment for four sets of intercom connections with a 1 RU form factor.


  • One Button for Echo Processing: One button designed for echo processing with the Digital Signal Processing (DSP) technology for echo elimination, easy and convenient.
  • 4W Audio Gain Adjustment: Ultrahigh ±6 adjustment range to effectively adjust the volume of both the wired and wireless system.
  • High-Definition Sound Quality: Interconnect with several wired and wireless intercom systems while retaining high-definition sound quality.
  • 4-Set Combination for 1 RU Standard Setup: Supports standard 1/4 RU structure accessory for 4 sets of 2/4 wire connections for flexible daisy-chain and broader communication coverage.
  • 2-Wire Connection for Direct Power Supply: Direct power supply from a 12 to 36V 2-wire connection with the wired system, no additional power supply needed.
  • Terminating Resistor Switch: The 220-ohm terminating resistor switch supports effective interconnection between SYSCOM 1000T and different models of Datavideo wired intercom systems.
  • Distance Compensation Switches: Two distance compensation switches for easy distance setup to meet up to 656′ cable length between the wired system and the converter.
  • Voltage and Static Protection: The voltage-protection design effectively prevent damage to the equipment by overvoltage input, while an electrostatic discharge (ESD) ±6000V test avoids ESD damage in dry or humid environments.
  • Compatibility: The 2-wire interface is compatible with ALTAIR, Hanson, ClearCom, RTS, Datavideo, and other types of wired intercom systems.
