System Overview  
The DELTA X10 and X12 Wireless Sound Systems are powerful, rugged, and durable amplification systems designed for medium  
to large-sized groups both indoors and out. The systems contain inputs for up to two UHF wireless microphone receivers,  
optional integrated CD Player, two inputs for wired microphones, and an input for a line level audio source coming from a DVD  
player, TV/VCR, Computer, etc. There is also a line output to connect to an external source such as a mixing console, an assistive  
listening system or a recording device. Users can also connect to a passive speaker or a powered speaker in order to cover a  
larger area. The systems operate on rechargeable battery power for up to 10 hours, and can also be plugged into AC power if  
longer run-time is desired. An optional 12VDC cigarette lighter adaptor provides the ability to operate the systems using the  
battery in your car in situations where there is no AC power available.  
The wireless receivers contain 100 user-selectable frequencies ranging from 620 MHz to 745MHz. Each receiver contains a Clear  
Channel Scan feature (a touch of a button automatically selects a clear frequency), low battery indicator (for the transmitter), and  
adjustable squelch control. The systems are available with a variety of handheld, lapel, and headset microphones.

CHARGING THE BATTERY  
After unpacking the unit for the first time, please charge the batteries for at least 10 hours before operation. The battery charger  
is built in as an integral part of the system. To charge the batteries, plug one end of the IEC power cable into the MAINS  
connector and plug the other end into an AC outlet (90-264VAC, 47-63Hz).  
1. CHARGING STATUS LED: The Charging Status LED will light up when external power is supplied. The color of the LED  
indicates the charging status as follows:  
• RED means fast-charge mode. The batteries are very low or completely discharged.  
• ORANGE means trickle-charge mode. The batteries are not yet fully charged.  
• GREEN means no charging. The batteries are fully charged.  
NOTE: If the batteries are low and there is an AC outlet available, you can connect the AC  
mains and operate the system as normal while the batteries are charging. However, to fully  
charge the system, it should be switched OFF until the CHARGING STATUS LED turns green.  
DETERMINING BATTERY STATUS  
2. BATTERY STATUS LEDs: The Battery Status LEDs indicate the amount of charge available even when the AC mains are  
disconnected. Whenever the batteries have enough charge to operate the system, the green OK LED will light. As the  
batteries discharge, the red LOW LED will begin to glow, and the green OK LED will stay lit. When the red LOW LED is  
glowing brightly, the battery is very low. Once the batteries discharge to an unusable level, the system will shut off and you  
will need to connect to an external power source.  
NOTE: It is possible to operate the system from a 12VDC external source when the batteries  
are fully discharged and no AC power source is available. A special adaptor cable allows  
connection directly to a car cigarette lighter. Contact LightSPEED for more information.  
SYSTEM POWER  
3. The POWER switch has three positions as follows:  
A. ON Position: The green ON LED will light and the power amps will be active. This is the normal mode of operation  
with the internal and external speakers producing sound.  
B. OFF Position: No LEDs will light and the system is off.  
C. MUTE Position: The green ON LED and the amber MUTE LED will light and the power amps will be disabled. This is  
a special mode of operation in which all of the controls and functions work as normal, but no sound is produced by

1. MASTER VOLUME: The MASTER VOLUME control is used to set the overall level of the audio going to the speaker(s).  
Each individual input has its own level control, and all of these input signals are combined (mixed) into one signal that flows  
through the MASTER VOLUME control.  
2. LIMIT: The LIMIT LED lights up to indicate when the limiter is active. The limiter helps to prevent distortion which can  
cause damage to the speaker system. The level of the signals coming from the inputs (microphones, CD player, LINE IN) is  
‘watched’ by the limiter circuit. The limiter instantly reduces the signal to a safe level if it becomes too large. When the limiter  
light is on, the power amplifier has reached maximum power.  
3. VOICE OVER MUSIC: This is a special feature that automatically reduces the level of the LINE/CD inputs whenever sounds  
are produced at any of the four microphone inputs (WIRELESS MIC 1, WIRELESS MIC 2, MIC 1 IN, and MIC 2 IN). After a  
few seconds of silence on the microphones, the LINE/CD signal will slowly return to its original volume level. This is handy  
for events that require background music with occasional announcements.  
The VOICE OVER MUSIC control sets the amount of reduction in level that occurs when the circuit is triggered by a micro-  
phone signal. For less reduction of the LINE/CD signal, turn the VOICE OVER MUSIC control clockwise. To disable VOICE  
OVER MUSIC, turn the control fully clockwise.  
4. TONE CONTROLS: The LOW and HIGH controls provide the ability to cut or boost the corresponding frequencies in the  
LINE/CD signal. These controls do not affect the microphone signals.

WIRELESS MICROPHONE OPERATION ... detailed operating instructions for receivers and transmitters are provided later  
in this manual.  
1. RF Indicator Lights: When both the system and the transmitter are on and operating on the same channel you will see  
an RF Indicator Light (either A or B) on the receiver.  
2. Volume Adjustment: While speaking into the microphone, slowly turn the up the volume on the receiver (while paying  
attention to the MASTER VOLUME). Remember that if the MASTER VOLUME is turned all the way down, no sound will  
come from the system regardless of the setting on the receiver volume.  
NOTE: Do not stand directly in front of the DELTA X speaker with the microphone on. This will result in  
feedback (‘squealing’ or ‘howling’). It is best to stand behind or off to the side of the unit when setting volume  
level. Detailed information about setting up wireless receivers and transmitters is provided later in this manual.  
3. Squelch Adjustment: In areas that may have very high radio frequency traffic, it may be necessary to adjust the  
squelch level to block out potential interference.  
• Maximum squelch (full clockwise) reduces system reception range, but also reduces the  
potential for system interference.  
• Minimum squelch (full counterclockwise) increases reception range, but also increases  
the potential for system interference.  
NOTE: In most cases it will not be necessary to adjust the squelch level.  
The Clear Channel Scan function will take care of most interference problems.  
4. Transmitter Low Battery Indicator: This LED will light to indicate the batteries in the corresponding  
transmitter are low and need to be replaced or recharged.

WIRED MICROPHONE OPERATION  
1. MIC IN: Connect the wired microphone into one of the XLR input jacks labeled MIC 1 IN and MIC 2 IN.  
2. LEVEL: Rotate the level control clockwise to increase the volume (while paying attention to the MASTER VOLUME).  
Remember that if the Master Volume is turned all the way down, no sound will come from the system regardless of the setting  
on the MIC IN LEVEL.  
3. LOW CUT Filters: These adjustments allow you to reduce the level of the low frequencies on each wired microphone  
input, making for a crisp and clear voice replication. The low cut filters affect only the associated wired microphone input.  
They do not affect the overall tone of the Delta X system.  
• To reduce the low frequency sounds (increase the low cut) turn the dial clockwise (towards “speech”) with a flat blade  
screwdriver.  
• If you desire a fuller sound for instruments or otherwise, turn the dial counterclockwise (towards “music”).  
NOTE: Do not stand directly in front of the DELTA X speaker with the microphone on. This will result in feedback  
(‘squealing’ or ‘howling’). It is best to stand behind or off to the side of the unit when setting volume level.  
Detailed information about setting up wireless receivers and transmitters is provided later in this manual.

CD PLAYER OPERATION  
Note: Detailed information about using the CD player is provided later in this manual.  
1. Volume Adjustment(LINE/CD LEVEL): While playing a disc, slowly turn up the LINE/CD LEVEL control until you reach the  
desired volume. Remember that if the MASTER VOLUME is turned all the way down, no sound will come from the system  
regardless of the setting on the LINE/CD LEVEL control.  
2. Voice Priority(VOICE OVER MUSIC): Audio coming from the CD player and the LINE IN jacks will automatically drop in  
level when sound is produced at any of the microphone inputs. When there is no more sound at the mic input(s), the audio  
from the CD player and/or the LINE IN jacks will come back to its original level. Adjusting the VOICE OVER MUSIC control  
changes the amount of drop in level that occurs when there is sound at the mic input(s).  
3. Tone Controls: The LOW and HIGH tone controls can be used to cut or boost the lows and highs in the audio coming from  
the CD player and the LINE IN jacks. These controls do not affect the audio coming from the microphone inputs.

CONNECTING TO ANOTHER DELTA X10 OR DELTA X12  
Using ACTIVE LINK, you can double the available inputs and double the sound level by connecting two Delta X10 or Delta X12  
units together. When connected properly, the sound from both Delta X systems is ‘shared’ between them.  
1. System Power Switch  
2. Control panel Active Link jack  
3. Active Link Cable  
4. Active Link Ground Lift Cable  
ACTIVE LINK cables are available from LightSPEED Technologies in various lengths. Before connecting the ACTIVE LINK cable,  
make sure the power to both Delta X systems is OFF. Put the Delta X systems in the locations that you have chosen, then  
connect the ACTIVE LINK cable between them.  
Note: If both Delta X systems are connected to AC mains power during operation, there may be an audible hum  
in the audio. If this happens, you will need to connect an ACTIVE LINK GROUND LIFT cable (provided) to one of  
the two Delta X units.

CONNECTING EXTERNAL SPEAKERS  
The Delta X10 and Delta X12 systems have two internal power amplifiers to drive loudspeakers. One amplifier normally drives  
the internal speaker and the other amplifier is dedicated for external passive speaker(s).  
1. EXTERNAL SPEAKER A SWITCHED: When you connect an external speaker to this amplifier, the internal speaker will be  
bypassed and only the external speaker will have sound.  
2. EXTERNAL SPEAKER B: When you connect an external speaker to this amplifier, the internal speaker will continue to  
produce sound along with the external speaker.  
Each external speaker connection will handle a load impedance of 8 Ohms or higher. You can connect a single 8 Ohm speaker or  
two 16 Ohm speakers in parallel to each external speaker output.  
Note: If the amplifier output cuts out on loud sounds, check the impedance of the external speaker(s).  
Loads of less than 8 Ohms will cause the amplifiers to shut down in order to prevent damage.

DETAILED OPERATION - WIRELESS RECEIVER  
Power up the Delta X system and wireless receiver(s)  
1.POWER: Push the POWER switch on the base unit back panel to the ON (or MUTE) position.  
2.ON LED: The ON LED will light.  
3.Receiver Volume: Rotate the Power/Volume knob on the receiver module clockwise to turn on. Leave the volume at a low  
level for now.  
4.Frequency Group: When the receiver power is first switched on, the frequency group of the receiver will be shown briefly  
as letters on the LED display. (See frequency group chart on page 30)  
Channel Selection - Wireless Receiver  
Each receiver has 100 user-selectable channels to choose from. You can select a channel either manually or by pressing the  
SCAN button which will automatically select a clear channel.  
5.Clear Channel Scan (Recommended): Make sure the transmitter(s) is OFF before pressing this button. When this button  
is pressed, the receiver will cycle through all 100 channels and select a clear frequency (this process takes about 20  
seconds). Once the receiver selects the clear channel, you will need to select the same channel on the corresponding  
transmitter (handheld or belt-pack).  
If You Have a Second Receiver (WIRELESS MIC 2): Verify that WIRELESS MIC 1 is operating on a clear channel, and the  
transmitter for WIRELESS MIC 1 is turned ON. Make sure the transmitter for WIRELESS MIC 2 is turned OFF, and then press the  
“SCAN” button on the WIRELESS MIC 2 receiver. After the WIRELESS MIC 2 receiver selects a clear channel, set the WIRELESS  
MIC 2 transmitter (handheld or belt-pack) to the selected channel.

8. SQUELCH ADJUSTMENT: In areas that have very high radio frequency traffic, it may be necessary to adjust the squelch level  
to block out potential interference.  
• MAXIMUM SQUELCH: (full clockwise) reduces the system reception range, but also reduces the potential for radio  
frequency interference.  
• MINIMUM SQUELCH:(full counterclockwise) maximizes reception range, but also increases the potential for radio  
frequency interference.  
Installing or Replacing a Receiver Module: Make sure the power to the  
Delta X system is turned OFF. Remove the two screws securing the module  
or filler panel using a small Phillips screwdriver. To remove the module,  
use a small flat-blade screwdriver. Carefully insert the blade under the face  
plate edge and nudge it outward. Grasp the edges with both hands and slide  
outward. Install the new module by aligning it with the guide rails and sliding  
all the way in to engage the connector at the rear of the module.  
Replace the two screws.

1. Transmitter Mute: The MUTE switch turns the transmitter’s audio signal on or off. The audio is off when the red LED is  
flashing.  
2. Gain Adjust: When changing microphones or users, it may be necessary to adjust the transmitter gain based on differing  
microphone sensitivities and voice levels.  
• To adjust the microphone gain, turn the MT dial clockwise to increase the gain and counterclockwise to decrease the gain.  
• If you are using a high impedence source, such as a guitar, it will be necessary to adjust the GT dial. Using a high  
impedance source requires a special cable. Contact LightSPEED Technologies for more information.

To play a disc, gently insert it into the CD slot. The CD  
player will ‘grab’ the CD and load it automatically. While  
the CD player ‘reads’ the track and time information, the  
display shows dashes.  
Note: Use PAUSE instead of STOP to maintain the playback  
position. Once STOP has been pressed, the playback will

quickly and hear ‘snippets’ of audio that you can use to listen  
for the desired position.  
To remove the disc from the CD player, press the EJECT  
button.  
After a few seconds, the LCD screen will change to a  
display showing the number of tracks, the total playing  
time of the disc, and a grid showing up to 16 tracks that  
will be played. The grid is very useful when programming  
playlists.

Trouble Shooting Guide  
No sound when using any input (CD player, Line In, Wired Microphones, Wireless Microphones):  
1. DELTA X main power should be turned ON. The green ON LED should be lit. If it does not light when the system is switched  
on, the battery is most likely too weak and needs to be plugged into the charger.  
2. Make sure the main power switch is set to ON and not MUTE.  
3. Check the setting of the MASTER VOLUME control. This control sets the amount of audio coming out of the speakers. If it is  
set to minimum, no sound will be produced.  
No sound when someone speaks into the wireless microphone:  
3. Microphone/transmitter power should be turned on. If the LCD display does not show, the batteries are most likely too weak.  
Plug the microphone/transmitter into the charger (if the batteries are rechargeable) or replace with alkaline batteries.  
NOTE: Do not attempt to charge alkaline batteries! This can result in severe damage to the transmitter that will  
NOT be covered under warranty!  
4. The transmitter and receiver should be set to the same channel and the blue RF LED (A or B) on the receiver should be lit.  
5. Verify that the receiver and transmitter are in the same frequency group.  
• Turn the receiver off and then on again. The letter code for the frequency group will be shown briefly on the LED display.  
• Open the battery compartment of the transmitter and find the frequency group sticker. The letter on the frequency group  
sticker must match the letter code shown on the receiver display.  
6. Make sure the red LED (on the belt-pack transmitter) is not flashing.  
The wireless microphone is experiencing drop-out or interference:  
1. The wireless frequency being used may not be a clear channel. Turn the transmitter off and press the SCAN button on the  
receiver to find a clear frequency. Then make sure to select the same channel on the transmitter.  
2. Squelch adjust on the receiver is set too high. If this squelch is set too high (fully clockwise), this can drastically reduce the  
range of the transmitter, resulting in more frequent dropout.  
3. Squelch adjust is set too low. In areas of severe interference (large downtown urban areas, airports, military bases, etc) it  
may be necessary to turn the squelch up slightly to avoid outside interference.  
4. Transmitter is out of range of receiver. The transmitters do have a maximum range of about 300-350 feet in an open field  
environment. This range can be dramatically reduced indoors and when large objects (such as a wall) may be obstructing the  
path directly between transmitter and receiver. If this is the case, it may be necessary to position the two closer together.  
5. Batteries are very weak. Just before the batteries are about to die, the overall performance of the system can degrade  
dramatically. Make sure to check the battery status of both the transmitter and DELTA X system.
