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.

The 2-wire interface is compatible with ALTAIR, Hanson, ClearCom, RTS, Datavideo, and other types of wired intercom systems.
