also be enabled on the transmitter.
Talkback works the same way in either the SWITCHED
or RATIO diversity modes, but ONLY works in the NU
HYPR compatibility mode.
NOTE: When Talkback is enabled, only receiver 1 and
a blinking TB will appear in the Main Window.
COMPAT
The IFB SER compatibility mode allows the receiver to
be used with Lectrosonics wireless IFB transmitters in
the same frequency band that may be available in the
future.

TUNING
In addition to the NOR (normal) mode, this screen also
allows selection of two user programmable frequency
groups (Groups u and v).
•
NOR
allows selection of all frequencies that the
receiver picks up. Each press of the UP or DOWN
button will step in 100 or 25 kHz increments to the
next frequency.
• u, v allow up to 16 user-selected frequencies to
be stored in each group. Each press of the UP or
DOWN button will step to the next stored frequency
in the group.
NOTE: The TUNING setup screen only selects the
tuning mode (NORMAL or Group Tuning). Frequencies
are chosen through the frequency setup screens as
shown below.

When any tuning mode
other than NOR is
selected, the frequency
screen will include the
selected tuning group
number.
If the selected frequency is not in the tuning group, the
tuning group indicator will blink.

NOTE: When a tuning group is selected, the available
frequency selections will be limited to those that are in
the tuning group.
In a compatibility mode other than HYBRID, no battery
telemetry information is available, so the TXBAT setup
screen offers only two choices:
•
---
(no timer) - Display no transmitter battery status
in the main window.
•
TIM
- Monitor the transmitter battery status with the
battery timer in the LCD Main Window.
NOTE: To reset the timer, set the TXBAT mode to
anything other than 9VT or AAT, then back to the
desired mode.
USING THE GROUP TUNING MODES
Press MENU to select receiver 1 or 2.
When a tuning group is
selected, a letter will appear
next to the frequency.

The group letter in the display will blink if the selected
frequency is not included in the group.
The letter will blink when
a frequency outside of the
tuning group is selected.

When no frequencies are stored in groups u and v, the
UP and DOWN buttons will function the same as in the
NOR mode.
When only one frequency is stored in group u or v, the
UP and DOWN buttons will not change the frequency. In
this case, hold the MENU/SEL button in and then press
UP or DOWN to scroll to the desired frequency.
To add a frequency to tuning either group u or v, Select
the desired frequency, then hold the MENU/SEL button
in and then hold the UP or DOWN button in until the
letter stops blinking.
To delete a stored frequency, select it with the UP and
DOWN buttons, then hold the MENU/SEL button in,
then hold the UP or DOWN button in until the letter
starts blinking.
STEPSIZE
Selects the frequency increment on each receiver to 25
kHz or 100 kHz.
SmtNR
This setup screen is available only in the Digital Hybrid
COMPAT (compatibility) mode. Select the desired mode
while listening to the audio to of one of three choices:
•
OFF
provides no noise reduction for complete
transparency, which is useful in controlled environ-
ments with very little high frequency noise such as
an indoor motion picture production set.
•
NOR (normal)
applies a moderate amount of noise
reduction to noticeably reduce hiss from subtle
sources such as electret microphones.
•
FULL
is very similar to the Lectrosonics noise
reduction system used for many years in legacy
analog systems. Hiss from electret microphones
and some environmental HF noise are suppressed.
PHASE
This setup screen allows the audio output polarity to be
inverted to match other microphones or audio sources.
