performed (by pressing and holding the UP or DOWN button), a clear Group/Channel˝
will be chosen and appear on the display. It will be one of the 207 predesignated
frequencies available in your system (see page 31). The SCAN function takes the
guesswork out of finding the best available frequency and is also handy for adding more
systems into the mix.
Group/Channel˝ can also be controlled manually from the menu. Activate the menu (see
previous page). When GROUP˝ appears, press SET. The current Group˝ will be displayed.
Press either the UP or DOWN button to scroll to another Group˝ and then press SET. The
new Group˝ will be saved and will appear on left side of the display.
Hint: The word CHANNEL˝ will appear to the upper right of the number. This means the
display is in Channel mode. The menu displays Group/Channel˝ as the default. Press the
SET button (quickly) and the Frequency˝ will appear on the screen. After 5 seconds it will
default back to Group/Channel˝. To set Frequency˝ as the default display see Display˝
(pg 18).
To change the channel, go to CHAN˝ in the menu (it’s next in line after GROUP˝) and
press SET. The current channel will be displayed. Scroll through the channels and select
the one you want, then press SET. The same applies if Frequency˝ has been selected as
the default.
LEVEL
This setting allows for additional gain control over the receiver. The factory setting is +6, a
good gain setting for Audix dynamic microphones. The VX5 condenser microphone has
much more output than a dynamic microphone and is better suited in the -6 or -9 range.
Hint: The key to a good sound with the least amount of noise and distortion is finding
the balance between the mixer, the receiver and the capsule gain. A soft singer, for
example, will require more gain on the mixer and receiver, which could potentially add
some noise into the system. Fine tuning the receiver setting can be helpful in these cases.
A loud singer, on the other hand, will require less gain and possibly a gain reduction on
the transmitter itself for control over distortion.
SQUELCH
Squelch is an important design facet of a wireless circuit. It mutes or suppresses noise
from the receiver in the absence of a desired signal. Typically, the lower the squelch, the
less signal it takes to activate the receiver. The higher or tighter the squelch, the higher
the signal required. Squelch also affects operating distance. Unless you run into extreme
conditions where you need more or less operating range than normal, we recommend
keeping the squelch around the factory setting of +15.
