Setting Up and Using Your VHF TD Series/ VHF Series System

9.Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. Next, make sure that your transmitter is unmuted by setting its Audio switch to “On.” Then set the Volume knob on the VR3TD or VR3 fully counterclockwise. If you are using the VH3 transmitter or if you are using the VT3L transmitter with a connected lavalier microphone or headset, speak or sing into the mic at a normal performance level while observing the VR3TD or VR3 front panel AF Level meter.

If you are using the VT3 transmitter with a connected instrument, play the instrument at normal performance level while observing the VR3TD or VR3 front panel AF Level meter. If the “100%” (unity gain) segment is lighting steadily, with just occasional higher excursions, the audio level is correctly set. If not, use the supplied plastic screwdriver to slowly adjust the VH3, VT3L, or VT3 Gain control (trimpot) until the VR3TD or VR3 AF Level meter “100%” (unity gain) segment lights steadily (with occasional higher excur- sions). Then slowly raise the VR3TD or VR3 Volume knob to the 2 o’clock position (unity gain) and, finally, set the volume of your amplifier/mixer until the desired level is reached. If you are using a VT3L beltpack transmitter equipped

with a lavalier microphone, note that correct lavalier placement is critical to sound quality. We recommend that you place it as shown in the illustration on the right— as close to your mouth as possible but off to one side (to minimize nasality) and unobstructed by clothing. Bear in mind also that

omni microphones (mics which pick up signal from all directions) are more prone to feedback problems than unidirectional (cardioid or supercardioid) ones; in general, you can avoid feedback by taking care not to use any microphone directly in front of a PA speaker

(if this is unavoidable, try using an equalizer to

attenuate those high- or mid-range frequencies which are causing the feedback “squealing”).

10.If you hear distortion at the desired volume level (or if the “125%” segment LED in the AF Level meter is lighting frequently), first check that the VR3TD or VR3 rear panel Audio Output Level switch is set correctly. Next, make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details). If you still hear distortion, do the following:

•If you are using a VH3 handheld transmitter or an VT3L transmitter with connected lavalier microphone or headset, its Gain control has been factory preset to provide optimum level for the particular microphone model being used and so no adjustment should be necessary. Any distortion present should therefore simply be a matter of the microphone being too close to the mouth; try moving it further away. If this does not solve the problem, use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VH3 or VT3L slowly counterclockwise until the distortion disappears.

•If you are using a VT3 transmitter with an instrument such as electric guitar or bass, lower the output level of the instrument until the distortion disappears. Alternatively, you can use the supplied plastic screwdriver to turn the Gain control (trimpot) on the VT3 slowly counterclockwise until the distortion disappears.

Note that, following this setup procedure, you can always lower the Volume knob of the VR3TD or VR3 in order to further attenuate the output signal if necessary.
