Using talkover.
Press the red button to use the “talkover” feature, which auto-
matically lowers the volume of all other inputs (including optional
CD) when speaking on the microphone.
When to use talkover.
Use talkover when making voice announcements over music or other program
material being played through the sound system (without having to manually
adjust the other volume controls). When you stop speaking into the micro-
phone, the volume on other inputs smoothly returns to normal in 3 seconds.
Note: The talkover feature is assigned to optional wireless mic 1 if installed;
otherwise, it is assigned to the mic 1 XLR input.)
CD/MP3 player operation.
See separate instructions for operation and features of the CD/MP3 player.
Setting the EQ controls.
Use the 3 equalizer tone controls to adjust for best sound quality and clarity. The
top-center mark indicates a ‘flat’ response.
For outdoor / voice applications:
Set the voice switch to “loud” for outdoor and other applications where powerful
voice projection is needed.
Turn the “low” control to the 9 o’clock position for maximum voice clarity
(reducing the bass level will also increase battery life).
For indoor and/or music playback:
Set the controls to the flat (12 o’clock) position, then adjust for desired sound
quality (be sure the voice switch is in the “normal” position).
Set the voice switch to the “normal” position when playing music and for most
indoor applications.

Getting started.
Whether you’re a first-time user or an experienced presentation professional, the Sound
Machine SM-4neo was designed with you in mind. Easy to use and loaded with features,
you’ll need only a few minutes to set up and begin operation. This user guide is full of
valuable information — please read it!
!! Charge the battery!
Your SM-4neo is shipped with the battery fully charged. If stored for more than
two weeks before use, plug it in to top off the battery. See “Charging the battery”
on page 5.
1. Set up the sound system in front of your audience.
Proper set-up is important. For best sound distribution, put the unit on a
speaker stand or table so the sound projects over the audience.
Connecting an SM-4C Companion Speaker.
For expanded crowd coverage, connect unpowered
companion speaker SM-4C to the speaker output
jack on the lower panel of the Sound Machine.
Note: The speaker output is designed
specifically for use with the Sound Machine SM-4C companion
speaker and SC50-4W or SC100-4W cable — DO NOT use other
type external speakers or damage may result!
2. Plug a microphone or audio source into an input jack.
Connect a microphone, tape player or other source to the matching input jack;
turn down the corresponding volume knob
before turning on the SM-4neo.
(See “Choosing an Input” on pages 6-7
for more information on input selection.)
If using the optional wireless microphone
system, use the corresponding knob to
control the input volume.
Note: See separate instructions for operation of the CD/MP3 player.

3. Turn the power switch ON
(plug in power cord for AC operation).
Observe LED indicators to confirm
battery level and power.
Battery Power (upper LED’s): The green light indicates the battery is at or
near full charge and ready to use. The yellow light means 30-60% usage
remains, and red means less than 30% remains and that the battery should
be charged before use (see “Charging the battery.” )
AC Power (lower LED): The SM-4neo automatically runs on AC power when-
ever the unit is plugged in and turned on. The green indicator on the bottom
row will light indicating full AC operation.
4. Adjust the volume level and sound quality.
Increase the volume of the input being used to desired level (be sure the
microphone or input source is turned on!) Adjust equalizer and set voice
switch as necessary (see pages 6, 7 and 9 for more details).
Charging the battery.
!! For maximum operating time, charge the battery after
EVERY use.
While it does not harm the battery if the unit is left in a partially discharged
state, over time the battery's self discharge will result in a low battery.
Optimum charging is achieved when the battery is charged between 0 and 40
degrees Centigrade (32 - 104° F). If the outdoor environment is unusually
warm or cold, bring the system indoors before charging. (The Sound Machine
may be left plugged into an AC outlet during storage for optimum results.)
Charging the battery.
Turn the system “off” and plug the cord into a standard AC outlet
to charge the battery. The unit automatically begins charging,
indicated by the flashing charge LED.
When the charge LED lights steady, the battery is fully charged
and the unit is ready for use or storage.

Dual wireless system set-up.
Follow these steps to set-up a Sound Machine with two wireless systems:
1. Turn the sound system “on”, and turn all transmitters “off”.
2. Perform Automatic Frequency Selection on the first receiver (see page 11).
3. Turn the first transmitter “on.”
4. Perform Automatic Transmitter Setup (see page 11).
Leave the first transmitter on. Repeat for steps 2-4 for the second system.
!! Note: Be sure that only one transmitter’s IR port is exposed when syn-
chronizing a system.
Manual Frequency Selection (receiver only)
To manually select a group or a channel, press and hold the channel button.
The display alternates between the group number and the channel number.
Releasing the channel button while either number is displayed makes that
displayed number flash. Then, press the channel button while the number is
flashing to increase the setting by one.
To activate the newly-selected group or channel, simply wait until the number
stops flashing.
Receiver locking feature.
The wireless receiver has a locking feature which prevents accidental channel
changes.

Wireless system set-up.
Each transmitter and receiver pair must be the same frequency, or channel. The
Shure wireless system uses transmitter setup to synchronize the transmitter and
receiver channels.
Note: transmitting devices such as cellular phones may interfere with wireless
audio transmissions. Keep transmitters and receivers away from these and
other potential sources of interference.
Single wireless system set-up.
1. Automatic Frequency Selection: Press and release the channel button.
This scans for a clear channel and sets the receiver to that channel.
2. Automatic Transmitter Setup: Turn transmitter “on”. Open the transmitter’s
battery compartment to display the infrared (IR) port (see pages 9 and 10).
With the transmitter IR port exposed to the wireless receiver, press and
release the sync button until the red light stops flashing on both receiver
and transmitter.
When the receiver’s ready light glows green, the system is ready for use.
Close the transmitter battery compartment.
