Care and Maintenance Problem Microphone is encountering feedback. Aux output does not sound right. Unable to send T4S/T8S audio to a computer through a USB connection. T4S/T8S is not responding to flash drive. What to do • Orient the microphone so that it is not pointing directly at its respective loudspeaker. • Try a different microphone. • Try a different position for the L1 system and/or vocalist on stage. • Increase the distance from the L1 system to the microphone. • Reduce the HIGH frequencies by adjusting the zEQ on the microphone channel. • Try notching out a particular frequency that could be causing the feedback by adjusting the Para EQ on the microphone channel. • Temporarily bypass any audio effects used (Mod, Delay, Reverb) to see if they might be contributing to the feed-back problem. • Check if the Aux output is configured for the desired tap point for each input channel. Refer to "Routing Input Signals to the Aux Output" on page 21. • Verify that each input assigns the desired signal level to the Aux output. • Check that the USB cable is properly connected to the mixer and computer. • Try a different USB cable. • Make sure the mixer is turned on. • Verify that the desired mixer input channels are assigned to the left and right USB output channels. See "USB to PC" in the Prefs menu. • Make sure that the Trim level of the respective input channel is turned up enough so that the green LED is on, indicating that there is a strong input signal. • Check the Input and Output level meters under the Prefs menu to confirm that there is a signal at both the input and output stages. • Verify that your computer USB input is working by connecting another USB-compatible audio device. • If you are using recording software on a computer, check the software requirements. You may need to configure the software settings for 48 kHz/24-bit operation. • To determine if there is an issue with your flash drive, connect a different brand flash drive English - 45
