  • Page 2 Two RF modes for reliable transmission Two RF modes for reliable transmission The DWZ Series provides two selectable RF modes. Simply choose the one that makes best use of your actual 2.4 GHz RF environment: Wide Band Hopping mode This mode reduces interference to other wireless equipment used in the same environment such as WiFi. There’s no need for advanced technical knowledge about radio frequency. Wide Band Hopping mode also supports additional error correction for more secure transmission*1. Narrow Band Hopping mode This mode helps to avoid interference from other devices – for example, 2.4 GHz wireless remote controllers that are commonly used for lighting control. This enables frequencies to be coordinated when using multiple wireless systems simultaneously*2. *1 Audio delay: Approx. 6 ms *2 Audio delay: Approx. 3 ms © 2004 - 2021 Sony Corporation.

  • Page 3 Intelligent Feedback Reducer function Intelligent Feedback Reducer function The Sony Intelligent Feedback Reducer can suppress unwanted feedback (howling) with high-performance DSP and Sony’s unique algorithms designed to eliminate feedback before it becomes unbearable. Up to 1024- band suppression filters are continuously tuned automatically in real time, eliminating feedback and avoiding deteriorating the original signal; this delivers the highest quality sound that can be enjoyed by presenters, vocalists and audiences. You can freely select the audio outputs to which you want this feedback reduction filter to apply – for example, you can output original audio to the main PA system, while processed audio is delivered to your monitor speakers. Stable transmission Stable transmission Interruptions in reception (signal dropout) can be a problem with wireless microphone transmission systems. With the DWZ Series, however, dropouts are reduced to a minimum. Utilizing a space diversity reception system, stable reception is achieved by using dual-antenna inputs / reception circuits. These receive signals over two different paths and automatically select the stronger RF signal for output. Highly secure transmission Highly secure transmission The ZTX-HR70 offers AES 128-bit standard encryption technology to secure transmitted signals and avoid being intercepted by others.
