OPERATION WGT Instrument Bodypack Transmitter 1. Snap open the BATTERY COMPARTMENT (25) and insert a fresh 9V BATTERY (26), observing the correct polarity. Close the compartment. The WGT-15 is provided with a 3.5 mm LOCKING JACK (27) for connecting the INSTRUMENT CABLE (28). To secure the connection, turn the metal slip ring on the plug clockwise to thread it on to the jack. To unplug, reverse the process. Slip the transmitter into a pocket or clip on to your clothes or instrument strap. (Note: As the cord to the instrument also serves as the antenna, be sure to extend it fully for maximum range. Rolling up or shortening the cord may reduce the effective operating range.) 2. Turn on the WGT by sliding the OFF/STANDBY/ON SWITCH (29) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (30) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED either will not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. 3. The WGT transmitter is now ready to use. The TX DISPLAY LEDs (7) on the 401X Quad receiver should now be lit, indicating a received signal from the transmitter. Adjust the volume of the receiver as per the Audio Output Instrument Connections section of the above 401X Quad receiver instructions. The AF LEVEL LED DISPLAY (7) on the 401X Quad receiver will light up as if the input signals are getting stronger. Occasional flickering on and off during use of the LED indicator is normal. However, if the LED stays on continuously, turn down the instrument volume control or noticeable distortion may result. For ultra high-gain instrument sources such as active bass pickups or even extra hot guitar pickups, an attenuation pad may be required to eliminate unwanted distortion. (Note: The INPUT LEVEL CONTROL (31) is not operable because it is preset and switched internally at the factory to instrument GT input mode. The control is only used for Headworn Mic (HM) and Lavalier (LT) input modes). (Note: Scratchy noises can sometimes occur when some electric guitars/basses 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 produce 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 220 pF capacitor soldered across the hot to ground terminals of the guitar's volume and tone pots.) 12
