Setting Up and Using the Synth Series 6 System
6. Next, select the Group and Channel for your transmitters and receivers. When two or more
transmitters and receivers are being used at the same location, all devices must be set to the same
Group (though each transmitter/receiver pair must use its own Channel) or intermodulation noise may
occur. Turn off the power to the UT6 or UH6 transmitter (using its Power On-Off switch) and use the
procedure described in the "UR6D System Settings" section on page 9 in this manual to set the Group
and Channel for each UR6D receiver, observing that receiver's RF Level display as you do so. If any
segments light (with the transmitter off), the selected Channel may be receiving interference and is
probably unsuitable for use (one segment lighting is insignificant). Select a Group that has the greatest
number of suitable Channels (that is, Channels where no segments light with the transmitter off).
See Appendix A on page 57 in this manual for more information. When you have decided which Group
and Channel you wish to utilize, turn the UT6 or UH6 transmitter's on (using its Power On-Off switch) and
use the supplied plastic screwdriver to set the same Group and Channel while observing the transmitter's
Unavailable LED. If this LED lights, you cannot use the selected Group and Channel—choose a different
one instead and set the UR6D receiver to match it.
7. When first setting up the Synth Series 6 System in a new environment, it's always a good idea to do a
walkaround while experimenting with different Group and Channel settings and observing the UR6D's
RF Level display—you may find that some cause more segments to light up than others (the more
segments light, the stronger the signal). Always pick the Group that has the greatest number of clear
Channels and the Channel providing the strongest signal. The basic rule of thumb for successful
wireless installations 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 (so that the person using the
transmitter can see the receiver antennas). You may also be able to improve RF reception by relocating
the receiver or repositioning the receiver antenna or (in the case of the UT6) the transmitter antenna.
8. Once you've settled on your Group and Channel assignments, it's time to set the audio levels.
If you are using the UH6 transmitter or the UT6 transmitter with a connected lavalier or headset
microphone, make sure it is unmuted (the Mute indicator in the UR6D display section should not be lit).
Then speak or sing into the mic at a normal performance level while using the supplied plastic
screwdriver to turn the Mic level control (trimpot) on the transmitter slowly clockwise until the "10"
segment (second from right) on the AF Level meter of the receiver lights most of the time. If you are
using the UT6 transmitter with a connected instrument, play the instrument at normal performance level
while using the supplied plastic screwdriver to turn the Instrument level control (trimpot) on the transmitter
slowly clockwise until the "10" segment (second from right) on the AF Level meter of the receiver lights
most of the time. This segment corresponds roughly to 0 vu.
9. Turn on your connected amplifier and/or mixer and set it to a low listening level. While continuing to
sing or speak into the mic at normal performance level (or while continuing to play an instrument
connected to the UT6 at normal performance level), slowly raise the receiver AF Level knob clockwise to
approximately the "4" position. Finally, slowly raise the volume of your amplifier and/or mixer to normal
listening level. When using the UT6 with some connected instruments, you may find that the signal
overloads when the AF Level knob at the "4" position; to remedy this, you can either lower the AF Level
(by turning the knob counterclockwise) or you can set the receiver's rear panel Audio Output Level switch
to the "-60" position. If you hear interference or noise, try changing channels or use the receiver rear
panel Antenna Attenuation switches to reduce the sensitivity of the antennas.
10. If you wish to keep the audio output signals from Receiver 1 (RX1) and Receiver 2 (RX2) separate,
make sure the Output Mixing switch on the rear panel is in the "Off" position. If you wish to mix the two
signals together, set the switch to the "On" position; the two output signals will then be mixed together
(at the relative levels determined by their front panel AF Level controls) and routed to all four balanced
and unbalanced output jacks.
