Attaching a Microphone or Musical

Instrument and Adjusting Audio Levels

The front panel Modulation LEDs indicate input level

and limiter activity. (See Modulation LED Signal Level

Table.) Since the distortion introduced by the limiter is

minimal and full modulation is assured, occasional red

flickering of the -20 LED is desirable.
Different voices or instruments will usually require dif-

ferent settings of the AUDIO LEVEL control, so check

this adjustment as each new person uses the system.

If several different people will be using the transmitter

and there is not time to make the adjustment for each

individual, adjust it for the loudest voice.
Musicians also vary their volume depending on the na-

ture of the music. It is suggested that the transmitter be

adjusted for the passage with the loudest volume.

1) If necessary, install a fresh battery.
2) Insert the 5-pin into the input jack. Ensure the pins

are aligned and the connector locks in (it will click).

For those using a musical instrument, insert the 1/4

inch plug on the other end of the instrument cable

into the appropriate jack on your musical instru-

ment.

3) Mute the main sound system or amplifier and rotate

the AUDIO LEVEL control on the transmitter to

maximum counterclockwise (Off).

4) Set the transmitter Power switch to ON.
5) For microphone users, position the microphone in

the location where it will be used in actual opera-

tion.

For musicians, adjust the instrument volume con-

trols to the highest levels that would be used during

a performance.

Selecting the Compatibility Mode

The LMa transmitter is capable of working with Lec-

trosonics 400 Series Digital Hybrid Wireless

, 200

Series analog, 100 Series analog and some non-Lec-

trosonics analog wireless receivers (contact the factory

for details). The transmitter must be set to the operating

mode of the matching receiver, which is easily done us-

ing the supplied screwdriver and a battery.

NOTE: The unit is supplied from the factory as a

400 series transmitter.

1) Ensure the battery is good.
2) Turn OFF the transmitter.
3) With a small screwdriver (one is included with your

unit), set the Frequency Select Switches to CC. (for

Change, Change).

4) Toggle the power switch ON briefly – just long

enough for the LED’s to light up and then turn it

OFF.

5) Change the Frequency Select Switches to one of

the following settings:

• 100 Series mode:

1,1

• 200 Series mode:

2,2

• Mode 3:

3,3

• 400 Series mode:

4,4

• IFB Series mode:

5,5

• Mode 6:

6,6

6) Toggle the power switch ON, then OFF again.
7) Change the Frequency Select Switches to 0,0.
8) Turn the transmitter ON to complete the operation.

The LEDS will blink to indicate the selected com-

patibility mode. Immediately after power up, all

LEDs will blink together red, then green, followed

by the audio level LEDs (-20 and -10) blinking to

indicate the mode.
The LEDs will blink:
• Once for 100 Series mode

• Two times for 200 Series mode

• Three times for some other receivers

• Four times for 400 Series mode

• Five times for IFB mode

• Six times for Mode 6

Note: Each time the transmitter is turned on, the

Modulation LEDs will confirm the current operating

mode with the number of blinks listed in Step 2.

The mode setting will not change until it is reset

with the procedure listed above.

Attention: During the procedure to set the

compatibility mode, each step between toggles

of the power switch must be performed within

ten seconds, or the procedure must be started

from the beginning.
