Portable Wireless Sound System

INSTALLATION AND OPERATING INSTRUCTIONS

1. Connect the power cord from the power

supply to the Power Input Jack.

Power Input Jack

DIV ANT

MAIN ANT

2. Attach the antennas or antenna cables to the

MAIN ANT and DIV ANT BNC connectors.

3. Press the POWER/PREV MENU button to

turn on the unit on. Check to see that the LCD
displays the Power Up Sequence.

LCD

POWER/PREV MENU

This is a sequence of three screens:

Lectrosonics
R400 V XX where VXX is the current

firmware version installed

Block XX where XX is the frequency tuning

range block number

After the Power Up Sequence is displayed, the
Main Window appears and the R400 is ready
for operation.

4. Ensure the receiver and transmitter are set to

the same Compatibility Mode, then, for units
with Firmware Version 1.5 and later, use
SmrtTun™ to locate a clear operating
frequency. Otherwise, use the Scan function
to locate a clear channel, or manually set the
receiver operating frequency via the Freq
setup screen. Then set the Transmitter
Frequency Select Switches to match the
receiver's operating frequency. (See R400
Menu Selections.)

5. Turn the

transmitter on and
verify that an RF
signal is indicated
on the LCD.

6. Connect an audio

cable to the BAL
AUDIO OUT XLR
jack.

7. Refer to the associated transmitter operating

instructions and adjust the transmitter gain.

Warning

This is perhaps the most important step in the set up

procedure.

In general, adjust the transmitter gain so that
the voice peaks will cause the audio
modulation level indicators on both the
receiver and transmitter to show full
modulation on the loudest peak audio levels.

Audio Level Bar

Normal levels should cause the R400's audio
level bar to fluctuate fully resulting in the best
possible signal to noise ratio for the system.

Note

A common mistake is to use the transmitter audio gain

control to set the overall audio level of the entire

system. The transmitter gain control is not a volume

control and must be set independently of the overall

system audio level. The transmitter gain control is only

used to set the proper modulation of the transmitter. It

is used to match the transmitter to the type of

microphone and the sound levels that will be present at

that microphone. We encourage users to either

disconnect the rest of the sound system or turn the

sound system gain to minimum to prevent either

feedback or overload as the transmitter gain is set.

Only after the transmitter gain control is set should the

gain of the rest of the audio system be adjusted to

achieve the desired sound or signal levels.

8. Use the Level or Tone menus to adjust the

audio output level to match the required input
level of any connected devices (camera,
mixer, recorder, etc.). The adjustment range is
from -50 dBu to +5 dBu in 1 dB steps.

Note

The test tone output is especially useful for an exact level

match. With the test tone running, adjust for the maximum

desired peak level using the metering on the connected

device.

9. If desired, access the LockSet menu to lock

the R400 front panel controls to prevent
inadvertently modifying the receiver settings
during operation.

PROGRAMMING USER GROUPS

For users who do their own frequency coordination, the
R400 offers two user-configurable frequency groups. Up
to 16 frequencies can be stored in a user group. Use the
following procedure to add or remove frequencies from
either user group (User Grp U or User Grp V).
