QUADRA
Transmitter Menus
To access the setup menus, press the MENU/SEL but­
ton at the upper left of the membrane panel. To back
up one level or return to the Main Window, press the
BACK button. The arrow keys along the right side of
the control panel allow you to navigate between menu
options and to adjust specific parameters within the
menu windows.
When the desired menu item is highlighted, press the
MENU/SEL button to enter the setup screen.
Selecting 2 Channel
or 4 Channel Operation
The Chan. Setup screen allows you to select whether
the transmitter operates in 2 Channel or 4 Channel
mode. This determines the width of the RF carrier, and
thus how many frequencies can be used in one place
at one time. In 2 Channel mode, the RF carrier is 2
MHz wide, thus yielding 8 available operating frequen­
cies. In 4 Channel mode, the RF carrier is 4 MHz wide,
thus yielding 4 operating frequencies.
NOTE: for the system to operate, the transmitter
and receiver must be in a compatible channel
setup (2 ch. vs. 4 ch.) Furthermore, note that
for the receiver to work in a Split Mode, the
transmitter must be in the 4 Channel mode.
Tuning
Once you have selected a channel setup, you can
choose an RF operating frequency. Generally, it is best
to use your receiver to determine the best operating
frequency with the tuning method described on p. 9. To
then select the matching operating frequency on your
M4T transmitter, use the up/down arrows to highlight
Tuning on the menu list, then press MENU/SEL. Here,
you can select from four operating frequencies in the 4
Channel mode or eight operating frequencies in the 2
Channel mode.
Once you have selected a matching operating fre­
quency, the blue LED on the front of your IEM receiver
should light up, indicating an RF signal lock.
Input Type
This screen allows you to choose between analog and
digital inputs, depending on your source from the
mixing console. From the main menu, use the up/down
arrow buttons to highlight Input Type. Press the
MENU/SEL to enter this page. Here, you have three
choices: All Analog, 1&2 Digital, and All Digital.
Because XLR inputs 1 and 2 also double as dual-
channel AES/EBU digital inputs, only these three
choices are possible.
NOTE: the M4T inputs are set to All Analog as
a factory default. If you send digital signals to
the input without changing the Input Type, the
system will transmit a loud white-noise signal to
the receiver. Also, if the receiver inputs are set to
Digital, and you are sending analog signals to
the inputs, there will be no audio present.
