SRb5P and SRb Dual Receivers
LECTROSONICS, INC. 16
Main Window
The appearance of the LCD Main Window will change
according to which diversity mode is selected:
• SWITCH (2-channel mode) splits the screen to
indicate activity and levels on both receivers and
transmitters.
• RATIO combines the audio outputs of both receiv-
ers to deliver a single audio channel.
With the DIV MODE set to
SWITCH, two audio channels
will be displayed.
With the DIV MODE set to
RATIO, a single audio channel
will be displayed.
Frequency Screen
Press MENU/SEL from the Main Window once for Re-
ceiver 1 and twice for Receiver 2. The selected receiver
is denoted in the upper left corner of the screen.
Press BACK to move from
Receiver 2 back to Receiver 1,
and again to return to the Main
Window
1 80
652.800
2 AF
657.500
In this example, the upper screen denotes that receiver
1 is set at 652.800 MHz, requiring that any transmitter
with hex switches be set at 80 for this frequency. Lectro-
sonics transmitters with LCD interfaces allow frequency
to be set in MHz or hex settings.
Press the UP and DOWN buttons to change the fre-
quency of the receiver. When the tuning mode is set to
NORMAL, the UP and DOWN buttons tune in single
channel increments. In the group tuning modes, the UP
and DOWN buttons step through the pre-coordinated
frequencies. (see the section on the next page entitled
Using the Group Tuning Modes)
Setup Screens
From the Main Window, press MENU/SEL three times
to enter the setup screens. Press UP and/or DOWN to
scroll through the available items and press MENU/SEL
to enter the desired screen. For those items that allow
separate settings for each receiver, press MENU/SEL
repeatedly to toggle back and forth between Receiver 1
and Receiver 2, then press the UP and DOWN buttons
to select the value or option, then press BACK to return
to the previous screen.
SHORTCUT: Hold the MENU/SEL button in while
pressing the UP or DOWN arrow to jump in 16
channel increments (1.6 MHz steps).
Menu Items
LEVEL
This setup screen displays the audio output level of the
receiver in dBu when the transmitter is fully modulated.
Press the MENU/SEL button to toggle between receiver
1 and receiver 2. Use the UP or DOWN buttons to
change the level. Range is from -50 to +5 dBu in 1 dB
steps. Press the BACK button to leave this screen.
The output levels at the two jacks may be set indepen-
dently, regardless of the diversity mode setting.
SCAN
This function provides a fast and reliable method of
finding clear channels for each receiver. Press SEL to
start the scanning. Follow the procedure outlined in the
navigation map on the previous page and on the page
entitled Scanning for Clear Frequencies for instructions
on using the scanner to find clear channels.
DIVMODE
The SWITCH diversity mode (dual channel mode) al-
lows the two internal receivers to operate independently
on different frequencies and settings with two different
transmitters. Diversity reception uses an antenna phase
switching technique on each receiver. When this mode
is selected, the setup screens will prompt you to select
the receiver to be adjusted.
The RATIO mode combines the two internal receiv-
ers to pick up the same transmitter and mix their audio
outputs for ratio diversity reception. Diversity reception
mixes the audio outputs in a ratio panning mode. In this
mode, the setup screens will prompt you for a single
value which will automatically be set for both receivers.
COMPAT (includes Talkback mode)
The
COMPAT setup screen selects the type of transmit-
ter used with the receiver. The available modes are:
• HYB is used with Lectrosonics Digital Hybrid trans-
mitters. This is the default setting and should be
used if your transmitter supports it. This mode offers
the best audio quality.
• 100 for Lectrosonics 100 Series transmitters.
• 200 for Lectrosonics 200 Series transmitters.
• IFB for Lectrosonics IFB transmitters.
• M.3, M.6 and M.7 are compatible with certain non-
Lectrosonics transmitters. Contact the factory for
details.
• HYB/TB selects the Talkback mode where the
audio is switched to channel 2 when the talkback
button on the transmitter is pushed.
When the Talkback mode is selected, the receiver is
configured so that the program audio output is on chan-
nel 1 and the talkback output is on channel 2.
The
Talkback mode is used only with a matching trans-
mitter such as the HH hand held model that includes
this feature. See transmitter manual for details.
