UHF Wireless Digital Hybrid TM Receiver
LEVEL, TONE, TXBAT, PHASE, SmtNR (in 500 Series
mode only), TUNING and COMPAT. 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.
LEVEL
The LEVEL setup screen shows the
audio output level of the receiver in
dBu. Use the SEL Up or Down
buttons to change the level. Range
is from -50 to +5 dBu in 1 dB steps.
Press MENU to leave this screen.
LEVEL
-50 dBu
TONE
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 SEL Up or Down buttons.
When the audio test tone is enabled, the received audio
is muted and an internally generated 1 kHz 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.

TXBAT
The TXBAT setup screen allows you
to select the exact battery being
used in the transmitter to provide
more accurate battery level monitor­
ing. 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 ad­
vance of battery failure. Press MENU to leave this
screen.
TXBAT
9V ALK
In native 500 Series mode as well as in the 300 Series
compatibility mode, the TXBAT menu offers six choices:
9V ALK - Transmitter uses a 9V alkaline battery. Monitor
voltage with battery icon in main window.
9V LTH - Transmitter uses a 9V lithium battery. Monitor
voltage with battery icon in main window.
9V TIM - Transmitter uses a 9V battery. Display its
voltage normally in the battery level window but monitor
its status with the battery timer in the main window.
AA ALK - Transmitter uses a AA alkaline battery. Monitor
voltage with battery icon in main window.
AA LTH - Transmitter uses a AA lithium battery. Monitor
voltage with battery icon in main window.
AA TIM - Transmitter uses an AA battery. Display its
voltage normally in the battery level window but monitor
its status with the battery timer in the main window.
The 9V TIM and AA TIM settings are most useful for
NiMH batteries as they do not exhibit reliably identifiable
voltage drops as they discharge.
In compatibility modes other than 500 Series and 300
Series, no battery telemetry information is available so
the TXBAT setup screen offers only two choices:
NOTIMER - Display no transmitter battery status in the
main window.
TIMER - Monitor the transmitter battery status with the
battery timer in the main window. To reset the timer, hold
MENU and DOWN for one second.
PHASE
The output PHASE setup screen
allows the audio output phase to be
inverted. The SEL Up or Down
buttons can be used to toggle
between normal and inverted phase.
Press MENU to leave this screen.

SmtNR
The SmtNR setup screen (available
in 500 Series compatibility mode
only) places the Smart Noise Reduc­
tion algorithm in one of three modes.
In the OFF position, no noise reduc­
tion is applied, for complete transpar­
ency. In the NORMAL position
(factory default setting), a moderate
amount of noise reduction is applied,
dramatically reducing hiss with
virtually no discernible side effects.
In the FULL position, the transpar­
ency is superior to the Lectrosonics
noise reduction system used for
many years in the 300 series sys­
tems. 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.

TUNING
The Tuning Setup Screen allows
selection of one of four factory set
frequency groups (Groups A through
D), two user programmable fre­
quency groups (Groups U and V) or
the choice to not use groups at all.
TUNING
NORMAL
In the four factory set frequency groups, eight frequen­
cies per group are preselected. These frequencies are
chosen to be free of intermodulation products. (See
Frequency Coordination.)
