CONGRATULATIONS!

Congratulations on your purchase of the Delta X6, the easy-to-use public

address system designed for gymnasiums, auditoriums, cafeterias and other large

meeting areas.

The Delta X6 contains inputs for up to two UHF wireless microphone receivers, one

input for a wired microphone and one input for a line level audio source coming

from a CD/DVD player, TV/VCR, Computer, etc. There is an adjustable-level audio

output to connect into an external source such as an assistive listening system or

recorder. Users can also connect to a passive speaker, in order to cover a larger area.

The system operates on AC power. The entire system and accessories ﬁt nicely in the

rugged carrying case, which makes it highly transportable and lightweight.

The wireless receivers contain 100 user-selectable frequencies ranging from 620 MHz

to 694.79 MHz. Each receiver contains a clear-channel scanner (a touch of a button

automatically selects a clear frequency), low battery indicator (for the transmitter), and

adjustable squelch control. The system is available with a variety of handheld, lapel,

and headset microphones.

When this button is pressed, the receiver will cycle through all 100 channels and select a clear frequency. (This process takes about 20 seconds.)

B) Once the receiver selects the clear channel, you will need to

select the same channel on the corresponding transmitter (handheld or belt-pack). See pages 11 and 16 for instructions.

If you have a second receiver:

A) Verify that Wireless Mic 1 transmitter and receiver are ON

and set to the same clear channel.

B) Make sure the transmitter for Wireless Mic 2 is turned OFF.

C) Press the SCAN button on the Wireless Mic 2 receiver.

D) After the Wireless Mic 2 receiver selects a clear channel, set

the Wireless Mic 2 transmitter (handheld or belt-pack) to the elected channel. See pages 11 and 16 for instructions.

3. Manual Channel Selection:

A) Pressing the left CHANNEL button changes the ﬁrst number (0-9).

B) Pressing the right CHANNEL button changes the second number (0-9).

Battery Type

The transmitter will operate with either standard AA alkaline batteries or nickel metal hydride (NiMH) rechargeable batteries. Since these types of batteries have different characteristics, it is important to set the transmitter to the appropriate type of battery being used so that the Battery Life Indicator will operate properly.

To change the Battery Type setting:

WARNING: Do not use NiCad batteries! They will not charge properly and may cause damage to the transmitter.

TROUBLESHOOTING GUIDE

If you review these instructions and still have questions, write down the serial number and model number of your system and call Lightspeed Technical Services at 800.732.8999, 5 a.m. – 5 p.m. PST.

NOTE: Most problems are directly related to low battery power. Please run through the “Battery Check” items ﬁrst. For remaining troubleshooting, use known good, fully-charged batteries.

No sound when someone speaks into the wireless microphone:

1. Delta X6 power should be ON. The

GREEN LED should be lit. If it does not light when the system is switched on, make sure the AC power supply is plugged in.

2. Microphone/transmitter power should be ON.

If the LCD display does not show, the batteries are most likely too weak. If the batteries are rechargeable, plug the microphone/transmitter into the charger. If the batteries are alkaline, replace them with new alkaline batteries

WARNING: Do not attempt to charge

alkaline batteries. They can overheat and expand, creating a signiﬁcant hazard and damaging the warranty. (This is not covered by warranty.).

3. The transmitter and receiver should be set to the same channel.

The BLUE RF LED (A

or B) should be lit.

4. Make sure the MUTE light is not ﬂashing.

Switch the transmitter/microphone off of MUTE.

5. Verify that receiver and transmitter are in the same frequency group.

Turn the Delta X6 OFF and then ON again. The letter code from the frequency group will blink on the receiver module. Open the battery compartment on the transmitter and be sure that frequency group printed on the sticker matches the frequency group letter code that blinked when the Delta X6 powered ON. If the letters are different, ﬁnd a microphone or belt-pack with the same frequency group as the receiver indicates when the Delta X6 is turned ON.

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 select the same channel on the transmitter.

2. Transmitter is out of range of receiver.

The transmitters have a maximum range of about 300-350 feet in an open ﬁeld environment. This range can be dramatically reduced indoors and outdoors when large objects (such as a wall) may be obstructing the path directly between transmitter and receiver. If so, position the two closer together.

3. Batteries are very weak. Right before

the batteries are about to die, the overall performance of the system can be drastically lessened. Check the battery status of the transmitter.

Low Volume or Feedback:

1. Ensure microphone is positioned appropriately.

2. Check volume level on the ampliﬁer. If the

volume is too high, feedback will occur. Adjust accordingly.

RF Indicator Lights: When both the system

and the transmitter are ON and operating on

the same channel you will see a BLUE glow-

receiver.

This LED will light to indicate the batteries in

the corresponding transmitter are low and

need to be replaced or recharged.

Adjusting the squelch level may be necessary

to block out potential interference in areas

that have that have very high radio trafﬁc.

NOTE: Do not stand directly in front of the Delta X6 speaker with the microphone on. This will result in feedback or ‘squealing.’ It is best to stand behind or to the side of the unit when setting volume level.

NOTE: In most cases it will not be necessary to adjust the squelch level. The system already has a clear channel scanner to take care of most interference problems.
