USB – POWER
The interface features a USB Type-B port and a 2.1 mm, 12 V, 1 A external power input, plus USB power, status, and external power LED indicators.
DMX Ports
The unit features 2 Neutrik XLR3 ports carrying the same DMX universe (512 channels). Each output is independently isolated and amplified for easier installation and greater system protection.
System Protection
What sets our equipment apart?
Opto-Isolated DMX Signal on Every Channel
Optocouplers create an optical barrier between each output channel and the interface control circuit. This electrically isolates both stages and protects them from electrical issues such as voltage spikes.
ESD Filters on DMX Inputs and Outputs
ESD filters help prevent unexpected behavior, malfunctions, and damage caused by electrostatic discharge, ensuring stable and reliable operation.
DMX Stage Voltage Isolated by External Power
In addition to optical isolation, complete output-stage protection requires separating the input and output power supplies. This is achieved with the external power supply.
EMI Filters on DMX Inputs and Outputs
EMI filters help prevent malfunctions and damage caused by electromagnetic interference, ensuring nearby equipment does not affect normal device operation.
Main Features

1 Universe
The TZ-1U provides one 512-channel DMX universe through two outputs, simplifying system installation.
Supported Operating Systems
Compatible software is available for multiple operating systems, including Windows, Linux, and macOS.
Dual DMX XLR Output
A built-in opto-isolated splitter provides two fully isolated outputs carrying the same DMX universe.
Maximum Devices per Output: 32
This limit is determined by the 120-ohm DMX impedance and the DMX512 USITT standard.
