Functional Overview

The ARTDMX A28 (CA-EN28) is designed for DMX-512 control signal amplification. It's especially designed for connections of DMX receivers (moving heads, color changers, dimmers etc.) in a daisy-chain configuration, and is suitable for applications in which the DMX-512 signal is weakened over long-distance transmission. ARTDMX A28 will efficiently buffer and magnify the DMX signal, ensuring the DMX data transmission is accurate and reliable.
