UHF Wireless Digital Hybrid TM Receiver
SETUP WINDOW
In the SETUP window, the UP and
DOWN buttons scroll through a list of
five possible destinations: EXIT,
LEVEL, TONE, TXBAT and PHASE
INVERT. Each of these destinations
allows a variety of settings to customize the receiver
operating parameters. Press MENU at the screen shown
here to return to the main window.
The LEVEL setup screen shows the
audio output level of the receiver in
dBu. Use the UP or DOWN buttons to
change the level. Range is from -50
to +5 dBu in 1dB steps. Press MENU
to leave this screen.

The TONE setup screen enables an
audio test tone at the receiver output
for precise level matching with other
equipment. The first screen prompts
you to press the UP button to enable
the tone at the receiver output jack.
The next screen that appears allows
the level to be adjusted in 1dB steps
using the UP and DOWN buttons.
When the audio test tone is enabled,
the received audio is muted and an internally generated
1kHz test tone is routed to the XLR connector. Since
there is only one audio output level setting for both
received audio and tone, the level set here will be retained
in the receive mode (it will supersede the setting made in
the LEVEL setup screen). The test tone has 1% distortion
and is intended for confirmation of output levels only. To
exit the test tone screen and stop the tone press the
MENU button.

The TXBAT setup screen allows you
to select the exact battery being used
in the transmitter to provide more
accurate battery level monitoring.
Four different types of batteries are
commonly used in Lectrosonics transmitters: 9 Volt
alkaline, 9 Volt lithium, AA alkaline, and AA lithium.
Correctly set, this will ensure that adequate warning will
be provided in advance of battery failure. Press MENU to
leave this screen.
The output PHASE setup screen
allows the audio output phase to be
inverted. The UP and DOWN buttons
can be used to toggle between normal
and inverted phase. Press MENU to
leave this screen.

The SmtNR setup screen places the
Smart Noise Reduction algorithm in
one of three modes. In the OFF
position, no noise reduction is
applied, for complete transparency. In
the NORMAL position (factory default
setting), a moderate amount of noise
reduction is applied, dramatically
reducing hiss with virtually no dis­
cernible side effects. In the FULL
position, the transparency is superior
to the Lectrosonics noise reduction
system used for many years in the
195 and 200 series systems. Try switching between the
three modes to decide what setting is correct for your
application. Refer to the Smart Noise Reduction section in
the GENERAL TECHNICAL DESCRIPTION chapter for
more detailed information about this feature.
