Selecting the Compatibility Mode and Power (SMV & SMQV ONLY)

SM Series transmitters will work with all Digital

Hybrid Wireless®receivers in the native, compand-

orless mode. They are also capable of working with

200 Series, 100 Series and IFB analog receivers,

plus some other brands of analog wireless receiv-

ers (contact the factory for details).

Note: RF transmission is prevented while selecting Compatibility

Modes. Also, the SM exits the Compatibility Mode screen to Standby

Mode. (See Standby Mode, this section.)

Note: The unit comes from the factory conﬁgured as a 400 Series

transmitter.

1) Set the receiver’s audio controls to minimum.

2) Power up the SM and observe the Boot Sequence. If the Compatibility

Mode for the SM does not match the corresponding receiver, then power

off the SM transmitter.

3) From a power off condition, press and hold the Up arrow, then press the

AUDIO and FREQ buttons simultaneously.

4) The LCD will display the current Compatibility Mode. Use the Up or

Down arrow buttons to set the Compatibility Mode to match the corre-

sponding receiver.

or 250mw).

Setting Transmitter Operating Frequency

The Operating Frequency of the SM is displayed

either in MHz or as a two-digit hexadecimal num-

ber. Pressing the FREQ button toggles between

the two display modes. The frequency can be set

with the unit in Standby Mode or while powered up

for normal operation.

Note:You must ﬁrst ﬁnd a clear frequency

with the receiver, then set the transmitter to

match.

To change the Operating Frequency of the SM

Series transmitter:

1) Press the FREQ button to enter this screen.

Note: The default display is in MHz. Pressing the FREQ button again

displays the operating frequency as a two-digit hexadecimal number.

2) While holding the FREQ button, use the Up or Down arrow buttons to

move the operating frequency up or down in 100 kHz increments from

the current setting. Holding the Up or Down arrows will cause rapid

scrolling through the frequencies.

Note: The operating frequency displayed on the LCD wraps as it

reaches the upper or lower end of its range. Thus, if you intend to

move the operating frequency from the lower end of the range to the

upper end, it may be faster to do this by using the Down arrow until the

frequency wraps to the upper end.

Adjusting the Low Frequency Roll-off

Repeatedly press the AUDIO button until the LF

roll-off adjustment screen appears. Then press and

hold the AUDIO button while selecting the desired

roll-off frequency with the UP and DOWN arrows.

The roll-off frequency can be set to 35, 50, 70, 100, 120 and 150 Hz.

Attaching a Microphone and Adjusting Gain

The front panel Modulation LEDs indicate limiter ac-

tivity. (See chart below.) Once set, the transmitter’s

audio level setting should not be used to control

the volume of your sound system or recorder levels.

This gain adjustment matches the trans-

mitter gain with the microphone’s output

level, the user’s voice level and the micro-

phone’s position. The audio input level can

be set with the unit in Standby Mode or

powered up for normal operation.

Note: Different voices will usually require different settings of the

AUDIO control, so check this adjustment for each person using 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.

1) With the SM powered off, insert the microphone plug into the Audio Input

Jack, aligning the pins and ensuring that the connector locks.

2) Place the SM in Standby Mode, or if the unit is to be powered up and ad-

justed, mute the main sound system prior to powering up the transmitter.

3) Position the microphone in the location where it will be used in actual

operation.

4) Observe the SM audio level LEDs while speaking or singing into the

microphone at the same voice level that will be used during the program.

While holding the AUDIO button, press the Up or Down arrow buttons

until the both the -20 and -10 LEDs glow green, with the -20 LED oc-

casionally ﬂickering red (+0 dB to +10 dB range during peaks).

Note: Setting the audio level too high reduces the dynamic range of the

audio signal. Setting the audio level too low may cause hiss and noise

in the audio.

5) If the unit was set up in Standby Mode, it will be necessary to power up

the SM and adjust the remaining components of the audio system prior to

use.

Locking or Unlocking the Control Panel

The Lock mode protects the transmitter from

accidental changes to its settings.

1) Ensure the SM setup is complete.

2) Simultaneously press both the Up and Down

arrow buttons to start the Lock timer. When

the timer reaches zero, “Loc” is displayed and

the controls are locked.

Important: The only ways to unlock a locked transmitter are to remove

the battery or unlock it via the remote control. It cannot be unlocked

or powered off using the buttons. The remote control will work only if

the transmitter was previously conﬁgured to respond to the remote

control.The unit will always power up in “unlocked” mode.

Battery Installation

We recommend using lithium or high-capacity

rechargeable batteries for longest life.

Note: Standard zinc-carbon batteries marked

“heavy-duty” or “long-lasting” are not adequate.

The battery status circuitry is designed for the volt-

age drop over the life of lithium batteries.

To install new batteries:

1) Turn the Battery Cover Plate Opener counter-

clockwise, open the battery compartment and remove any old batteries.

2) Insert the new battery (or batteries) into the housing, positive (+)

terminal ﬁrst.

Important: On dual-battery transmitters, BOTH

batteries go positive (+) terminal ﬁrst.

3) Replace the Battery Cover Plate and tighten the Opener.

Conﬁguring for Remote Control Use

Some transmitter settings can be changed with the

Lectrosonics RM Remote Control. However, you

must ﬁrst conﬁgure the SM Series transmitter to

accept commands from the RM:

1) Press and hold the Down Arrow Button then

power on the transmitter by pressing the

Audio and Freq buttons simultaneously.

2) The LCD will display the status, either “rc ON” or “rc OFF.” To change the

setting, press the Up or Down arrow button.

3)Power Off the transmitter by pressing the Audio and Freq buttons simulta-

neously. The RC setting will persist when you Power Up the transmitter

again.

Note: SM Series transmitters with ﬁrmware version 1.6 and later are

factory set to “rc ON” by default.

Conﬁguring for Power Restore (SMV & SMQV ONLY)

When using external power source through a

battery eliminator, Power Restore will return

your transmitter to settings it had before it was

powered off. This eliminates the need to power on

through the unit itself.

1) Press and hold the Down Arrow Button then

power on the transmitter by pressing the

Audio and Freq buttons simultaneously.

2) The LCD will display the status, either “rc ON” or “rc OFF.” Press “AUDIO”

or “FREQ” key to scroll to the “PbAc 0” setting and use arrow keys to

turn to “PbAc 1” for on.

3)When power is restored the unit will turn on with previous settings.

RM Remote Control Operating Instructions

The RM gives you remote control of SM Series transmitters using an audible

tone delivered to the transmitter’s microphone. When the SEND button is

pressed, a “dweedle” tone will play from the RM speaker and the parameter on

the transmitter will be set immediately. The transmitter must be conﬁgured to

accept commands from the RM (see page 6). Adjustments can be made to set:

• Audio input gain

• Frequency

• Lock or Unlock modes

• Sleep mode ON/OFF

In the power saving sleep mode, power consumption drops to 20% of normal.

Powering the RM On and Off

Press the AUDIO and FREQ buttons together brieﬂy.

Principles of Operation

The RM user interface is organized into pages which are accessible via the

AUDIO and FREQ buttons. Once on a page, settings can be adjusted with the

UP and DOWN arrow buttons. Only the speciﬁc function displayed is altered.

The AUDIO button cycles through 4 pages:

1) Aud - set transmitter’s audio level

2) SLEEP/unSLP - cause transmitter to sleep or wake up

3) Loc/unLoc - lock or unlock transmitter’s buttons

4) Loud - adjust RM speaker volume (press SEND button for a sample tone)

The FREQ button cycles through 3 pages:

1) CH - set transmitter’s channel (using block-independent hex code)

2) b - select a block number (optional — uncovers page 3)

3) 000.000 - set transmitter’s frequency in MHz (avail. if a block is selected)

Note: The speaker should be uncovered and

held within a few inches of the transmitter’s

microphone. The longest usable range is about

6 feet, depending on the microphone and volume

settings.
