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.
