Carvin UH6000 Instruction Manual - Page 7

The AF LEVEL LED DISPLAY (5) on the receiver will light up to 5 LEDs for all input signals. Occasional flickering on and off during use of the top red LED indicator in this display is normal, however if the red LED stays on continuously, turn down the instrument volume or the INPUT LEVEL CONTROL (33) on the transmitter, or noticeable distortion may result. (Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are used with any wireless system. For this reason, the supplied INSTRUMENT CORD (28) has a factory installed capacitor inside the 1/4" plug. This capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them: 1) Make sure all guitar volume and tone pots are clean and all contacts are solid-this is very important. 2) Provide extra filtering with a 47pf capacitor soldered across the hot to ground terminals of the guitar's volume and tone pots.) 6.Microphone Use (with either a lavalier or headworn microphone) Secure the connection from the LAVALIER (30) or HEADWORN MIC CORD (29) by turning the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not place it too close to the mouth-a distance of about six inches usually works best. To use the headworn mic, place it on the head and adjust the boom so that the mic is about one inch to the side of the front of the mouth. When ready to speak, slide the OFF/STANDBY/ON SWITCH (31) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above receiver instructions. [Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omnidirectional mics pick up sound equally from all directions and are prone to feedback if not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that are farther from the sound source, such a lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or headworn models that are used close to the mouth]. 10 FRONT PANEL REAR PANEL 12 3 4 56 78 9 10 11 12 13 14 9 15 16 17 1.
