Specifications Setup Quick Package Contents Package Compatibility Charts Compatibility 17 18 InformationSetup InstructionsQuick ReferenceSpecificationsPackage ContentsPackage ContentsInformation LT-800 Troubleshooting Troubleshooting The LT-800 has no power Make sure the LA-207 power supply is connected to a power source and is connected to the jack marked “Power Input”. Make sure the POWER button is pressed in. There is no audio or the audio level is too low Make sure that your audio source is properly connected to Input 1 and/or Input 2. The Input 1 or Input 2 switches must be in the correct position for the appropriate input level. For example: if you are using the output of a mixer on Input 2, the switch should be in the -10dBu position. If it were to be in the +10dBu position, the level would be too low. Also, check the Input knob to ensure it is properly adjusted. You should be able to see the VU meter deflect on Input 1 or Input 2 corresponding with the input level of the audio source. You can listen to the audio source by connecting a headset to the front panel jack and adjusting the Monitor volume control. If the level of audio into the transmitter is low and can’t be corrected using the level input switches, the audio processor can be turned on to boost the signal (see page 8 to set, page 12 for description of Process Mode). The audio is distorted Check to make sure you have the input level select switches in the proper position. You may be providing too much audio level for the input stage to handle. Make sure the SQ mode is set correctly on both the LT-800 and the receivers you are using. If your receivers do not have SQ, make sure the SQ mode is turned off (see page 8). There is hum in the audio Make sure you have properly grounded the audio source to the LT-800. Check the connections from the audio source to the LT-800. If you can, try to use a balanced audio source -this will reduce the chance of creating hum. Connect a ground wire from the LT-800 to ground and/or to the ground of the source audio. There is a tone The Test Tone button has been pressed (its LED light is on). Push the Test Tone button to turn off the tone. The Audio Input 1 sounds “tinny” If you are using an unbalanced audio source, make sure Pin 3 on the XLR or the ring on the .” plug is grounded (see page 9). I cannot pick up the signal on the receiver Check to make sure the receiver and the transmitter are using the same frequency band (i.e. 72 MHz or 216 MHz) and that they are on the same channel. Make sure the LT-800 has an antenna connected. Ensure that the receiver has an antenna (for portable products the headset is the receiving antenna). I can pick up the signal on the receiver, but it sounds like it’s not tuned in Check to make sure the transmitter and receiver are on exactly the same channel. It’s a good idea to lock the channels once they have been set. To lock the LT-800, press the UP button for 3 seconds (see page 10).
