Getting Started with GLX-D Digital Wireless – Part 3: Adjusting Gain

Setting the gain has never been easier with audio levels and gain settings visible on the receiver’s display.  “OL” indicates that the gain needs to be reduced – a simple matter of using the system’s gain buttons to increase or decrease the gain.  This short video shows you how.

    I have the glx tuner and also bought the rackmount version because I was told that I could use both packs for either system however I’ve found that the transmitter pack for the rack version distorts . Is there a gain adjustment on the pack? Because one pack is just fine

      Hi, Todd. There is no gain adjustment on the pack itself. One thing would be to make sure that the system gain on the receiver (GLXD4 or GLXD6) is not set too high – in most cases, keep it set at something close to 0 dB. Our customer service team would be happy to advise you further on what may be causing the distortion. Please contact them at
