Front And Rear Panels - Lectrosonics D4 Series Instruction Manual

D4T/D4R

Front and Rear Panels

On both the D4T and the D4R, the front panel interface
contains a power switch, an LCD display and eight
push buttons. The D4T has one antenna jack and the
D4R has two. The D4R front panel also contains a jack
for headphones.
When the units are powered on, an initial introduc-
tory splash screen is displayed; the Main Window then
appears and remains on the LCD until a setup screen
is selected. The Main Window shows four audio level
meters, one for each channel. (In two channel mode,
only two meters are shown.) Each audio meter bar
graph will switch to display the word CLIP to warn of
possible overload distortion at high levels. The D4R
receiver Main Window also includes an RF level meter,
headphone volume control and channel indicator.
Button functions are context-sensitive, but as shown
in the illustrations, the FUNC and BACK buttons may
be used to enter and leave various menus and setup
screens. No other buttons are active in the D4T's Main
Window – they are only used for setting up the D4T.

receptacle and the USB port (for firmware updates).

EBU digital signals. Jacks 3 and 4 are for analog
