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.

Each Receiver has 100 user-selectable channels to choose from. You can either select a channel
manually or by pressing the SCAN button, which will automatically select a clear channel.
2. When the system is switched on, the receiver will have two letters
flashing on the screen to indicate the corresponding frequency
group. (See Helpful Hint below)
3. Clear Channel SCAN (recommended):
A) 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.)
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).
C) Once a frequency is selected, you will need to select the same channel on the
corresponding transmitter (handheld or belt-pack). See pages 11 and 16 for instructions.

Battery Life Indicator
The battery life is shown on the primary screen of
the LCD. The 7-step fuel gauge acts as a detailed
guide to show the actual life of the battery.
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.
Lightspeed recommends Panasonic or Energizer batteries. Duracell may not work.

Replacing the Batteries:
1. Unscrew the end cap to reveal the battery
compartment.
2. Remove or replace the batteries as shown. The
microphone requires two AA sized batteries
stacked end to end.
3. Note the polarity in the battery compartment.
Recharging the Batteries (NiMH Rechargeable Batteries ONLY):
Make sure there are NiMH rechargeable batteries in the transmitter before
plugging in the charger.
IMPORTANT: Replace batteries with the same
type, (alkaline or NiMH), that were installed
in your Handheld Microphone. Lightspeed
recommends Panasonic or Energizer batteries.
Duracell may not work properly.
WARNING: Do not attempt to charge alkaline
batteries. They can overheat and expand,
creating a significant hazard and damaging the
transmitter. (This is not covered by warranty.)
