Crestron QM-AE QuickMedia™ Audio Extractor Problem Solving Troubleshooting The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative. QM-AE Troubleshooting TROUBLE POSSIBLE CAUSE(S) CORRECTIVE ACTION The QM-AE is not receiving power. Improper power supply. Use only Crestron power supplies for Crestron equipment. PWR LED does not illuminate. The QM-AE is not receiving power.
QuickMedia™ Audio Extractor Crestron QM-AE Appendix: QuickMedia Installation and Compensation Installation Notes You must pass audio through from transmitters to receivers even if you are not using the audio signal. The information required for auto-compensation is transmitted along with the audio. In addition, the QM Link signal indicates that the QM cable is connected and that an audio signal is present on the cable.
Crestron QM-AE QuickMedia™ Audio Extractor Auto Compensation with a Self-Peaking Receiver Crestron's innovative self-peaking audio circuit eliminates the need to peak the audio signal. Without self-peaking the same peak and boost values are applied equally to the video and audio signals. When these signals travel the same path, this arrangement is satisfactory. However, when video and audio travel to a receiver from different paths, unequal cable lengths are created.
QuickMedia™ Audio Extractor Crestron QM-AE Compatibility Charts Under certain circumstances, the audio and video may be acceptably peaked even though the audio and video path lengths are different. Because the audio signal is digital, and more forgiving than the video signal, it may be possible to peak the video and have functioning audio. It is difficult to predict outcomes because it is dependent on the difference in cable lengths, the video rates, and acceptable video quality.
Crestron QM-AE QuickMedia™ Audio Extractor KEY: 9 = Good operation. 1. = Operation depends on video rates and if the audio and video cable lengths are closely matched. 2. = In these cases, if the audio and video (although from different sources), switch together consistently, the system will operate normally. If the audio and video switch inconsistently, operation then depends on the video rates and how closely the audio and video cable lengths match. * = Device with self-peaking.
