7) Set Receiver Audio Output Level
The audio output can be adjusted from -50 dBu (mic
level) to +5 dBu (line level) in 1 dB steps. It is best to
use an output level high enough to drive the connected
device to an optimal level without the need for addition-
al gain. If the receiver is set to full output and the level
is still not sufficient to drive the connected device to an
optimal level, then some gain will need to be applied
by the connected device.
A built-in tone generator makes matching the output
level to the connected device easy and accurate.
1) Navigate to Audio Level in the LR receiver menu
and press MENU/SEL to enter the setup screen.
Use the arrow keys to reduce the level to minimum
(-50 dBu).
2) Turn on the 1k tone (MENU/SEL + UP arrow) in
the Audio Level setup screen.
3) On the connected device, set the input to "line
level" if available. Turn the input gain control (e.g.
record level) all the way down.
4) Gradually increase the output level on the receiver
while observing the input level meter on the con-
nected device. Increase the level until the input
level meter indicates 3 or 4 dB below maximum.
This "optimal level" will protect against overloading
the input with a very loud peak in the audio.
5) If this optimal level cannot be achieved, even with
the receiver output turned all the way up, increase
the input gain control on the connected device
gradually until this level is achieved.
Once this level match has been set, leave these set-
tings alone and make adjustments from one event to
another with the input gain control on the transmitter.
Firmware Update
As of the date of this writing, the firmware update pro-
gram runs only on a Windows operating system.
Updating the firmware is simply a matter of download-
ing a utility program and file from the web site and
running the program with the receiver connected to a
computer via the USB port.
Go to www.lectrosonics.com/US. Click on SUPPORT
in the top bar, then click on L-Series in the catego-
ries list. Click on the link labeled Firmware Updates
at the bottom of the screen. Download the Firmware
Updater program zip file and extract it to a temporary
folder on your computer. Then download and extract
the firmware zip file (e.g. lrv1_16.zip) and extract it to a
temporary folder on your computer.
Hold down the UP and DOWN arrow buttons on the
receiver while powering it up. The receiver will display
UPDATE to confirm it is in this mode. Plug in the USB
cable and run the utility program. The program will
automatically detect the receiver and prompt for the
location of the firmware file. Point at the file and click
on Start. The process takes about 90 seconds.

Antenna Orientation
The antennas are most sensitive perpendicular to the
axis of the whip. The pattern is a toroidal (donut) shape
surrounding the antenna. A cross section of the pattern
is depicted in the illustrations below.
The best orientation is to keep the antenna whips
elevated and oriented vertically to provide a circular
pattern around the transmitter and receiver. The whips
can point up or down.
The receiver can be mounted horizontally and swivel-
ing antennas can be adjusted to keep the whips in a
vertical orientation, as shown in Fig. 2.
It is also good practice to keep the antennas away
from metallic surfaces.
