Setting Up and Using Your VM1 System

13.Conversely, if you hear a weak, noisy signal at the desired volume level, again 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 it is and the signal coming from the VM1 is still weak and/or noisy, do the following:

•If you are using a VH3 transmitter, use the supplied plastic screwdriver to turn the Level control (trimpot) on the transmitter slowly clockwise (towards the “Max” position) until the signal reaches an acceptable level.

•If you are using a VT3L transmitter with connected lavalier microphone or headset, its 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 weakness of signal should therefore simply be a matter of the microphone being too far from the mouth; try moving it closer. If this does not solve the problem, use the supplied plastic screwdriver to turn the Level control (trimpot) on the VT3L slowly clockwise until the signal reaches an acceptable level.

14.Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the VM1 on. Then restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent— if it is, skip ahead to the next step. If it isn’t (that is, if you hear some noise), you may need to adjust the VM1 SQ (squelch) control, located in the battery compartment. When the SQ control is at its minimum setting, the VM1 system always provides maximum range without dropout; however, depending upon the particular environment your system is used in, you may need to reduce that range somewhat in order to eliminate band noise when the transmitter is turned off. To do so, use the provided screwdriver to rotate the SQ control completely clockwise (to the “Min” position), then slowly turn it counterclockwise until the noise disappears. If no noise is present at any position, leave it at its fully clockwise “Min” position (so as to have the greatest overall range available).

15.When first setting up the VM1 system in a new environment, it’s always a good idea to do a walkaround in order to make sure that coverage is provided for your entire performance area. Accordingly, turn on both the transmitter and VM1 receiver. If you are using a video camera, use the supplied velcro strip to attach the VM1 to the side of the camera. If not, physically place the VM1 in the position in which it will be used. Next, with the transmitter unmuted, walk through the entire area that will need to be covered while speaking, singing, or playing your instrument. As you do so, you will find that the orange “A” and “B” LEDs on the VM1 occasionally switch on or off, always showing you which antenna is receiving the stronger signal. The basic rule of thumb for all wireless audio systems is to always try to minimize the distance between transmitter and receiver as much as possible and also to try to maintain “line of sight” between the two (that is, the person using the transmitter should be able to see the receiver). Always try to minimize the distance between transmitter and receiver as much as possible so that the strongest possible signal is received from all planned transmission points.
