Setting Up and Using the

Series One 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 AF Level knob on the UR1 fully clockwise (to its “10” setting); this is unity gain. If you are using the UH1 transmitter or if you are using the UT1L transmitter with a connected lavalier microphone or headset, speak or sing into the mic at a normal performance level while slowly raising the volume of your amplifier/mixer until the desired level is reached. If you are using the UT1G transmitter with a connected instrument, play the instrument at normal performance level while slowly raising the volume of your amplifier/mixer until the

desired level is reached. If you are using a UT1L 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	UT1

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, first check to see whether the yellow “Peak” LED on the UR1 is lit. If it is not, 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 the yellow “Peak” LED is lit, do the following:

•If you are using a UH1 transmitter, use the supplied plastic screwdriver to turn its Microphone Input Level control (trimpot) slowly counterclockwise (towards the “Min” position) until the distortion disappears.

•If you are using a UT1L transmitter with connected lavalier microphone or headset, its Audio Input Level control has been factory preset to provide optimum level for the particular lavalier or headset 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 Audio Input Level control (trimpot) on the UT1L slowly counterclockwise until the distortion disappears.

•If you are using a UT1G 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 Level control (trimpot) on the UT1G slowly counterclockwise until the distortion disappears.

Note that, following this setup procedure, you can always lower the AF Level knob of the UR1 in order to attenuate the output signal if necessary.
