Setup Window
In the Setup window, the SEL Up
and Down buttons scroll through a
list of eight possible setup screens:
EXIT, LEVEL, TONE, TXBAT,
PHASE, SmtNR (in 400 Series
mode only), TUNING and COMPAT. Each of these
destinations allows a variety of settings to customize
the receiver operating parameters. Pressing the MENU
button accesses whatever setup screen is identified in
the Setup window. Pressing the MENU button whenever
EXIT is displayed returns the user to the Main Window.
LEVEL
The LEVEL setup screen displays
the audio output level of the receiv-
er 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 the MENU button to leave this screen.
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
SEL 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 and 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
monitoring. Four different types of
batteries are commonly used in Lectrosonics transmit-
ters: 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.
Use the SEL Up and Down buttons to select the trans-
mitter battery. Press MENU to leave this screen.
In native 400 Series mode as well as in the 200 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 volt-
age 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. Moni-
tor 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 identifi-
able voltage drops as they discharge.
In compatibility modes other than 400 Series and 200
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.
Note: To reset the battery timer, press and hold
MENU and SELECT Down together for one
second.
PHASE
The output PHASE setup screen
allows the audio output phase to
be inverted. The SEL Up and Down
buttons can be used to toggle be-
tween normal and inverted phase.
Press MENU to leave this screen.
SmtNR
The SmtNR (Smart Noise Reduc-
tion ) setup screen (available in 400
Series compatibility mode only)
places the Smart Noise Reduction
algorithm in one of three modes. In
the OFF position, no noise reduc-
tion is applied, for complete trans-
parency. In the NORMAL position
(factory default setting), a moder-
ate amount of noise reduction is
applied, dramatically reducing
hiss with virtually no discernible
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.
