Hollyland 2/4 Wire Converter for Intercom Systems
RM1796
Key Features
– Interconnect 2/4 Wire Intercom Models
– Distance Compensation up to 656′
– Static and Voltage Protection
– 3-Pin XLR Jacks for 2/4-Wire Systems
– 4W Gain Adjustment, HD Audio Quality
– Echo Processing, 2-Pin 12 to 36V Power
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
