SWAT-2.4 Manual 1
Earthquake Sound Corp. | (800) 576-7944 | www.earthquakesound.com
Introduction
SWAT 2.4 is a wireless audio transceiver that allows you to play audio material from your audio source
player to almost any speaker wirelessly. Hard wiring your speakers to your sound source is costly and
time consuming. SWAT 2.4 makes install a snap but does not compromise sound quality for convenience.
It is extremely versatile and perfect for apartments or outdoor settings. It even has microphone capability
so you can transmit voice as well.
SWAT 2.4 consists of a Transmitter (a unit that connects to the source) and a Receiver (a unit that
connects to the amplifier or powered speaker). The SWAT 2.4 Transmitter connects to a stereo, MP3
player, computer, or any other device that can play audio through a 3.5mm stereo jack or RCA output. The
Receiver is then connected to an amplifier or a powered speaker through an RCA input. Multiple
Receivers can connect wirelessly to one Transmitter if you want the music to play in different areas or on
multiple systems. Extra Receivers can be purchased separately.
Once the Transmitter and Receiver are paired, the Receiver will receive signals from the Transmitter
automatically. If there is any interference on the current channel, all you have to do is change to the
channel of the Transmitter; the Receiver can sense the frequency change and will adjust automatically. It
has 20 available channels, more channels than any other wireless transceiver has to date. There is also a
one in 20 million chance that the pairing channel will interfere with a different signal.
Both the Transmitter and the Receiver must be connected to a power source of which there are two
options. One is the DC power supply which connects to any wall outlet, and the other is USB.

maintenance instructions in this
accompanying literature.
Unpacking system components
• Keep the original carton and packing materials for future
shipment or storage.
• Check for any visual signs of damage. If you encounter any
concealed damage, consult your Earthquake Sound dealer
before proceeding with unit installation.
• Retain the sales receipt as it established the duration of the
limited warranty and provided information for insurance
purposes.
System installation considerations
There are several factors to consider before installing Earthquake
Sound’s SWAT 2.4.
• What are the intended listening zones?
• What system options and accessories might be required for
features such as local sources, etc.?
• From where in each zone will the listener prefer to control the
system? Where will the remote gains be located? Where will the
speakers be located?
• Where will the source equipment be located?
Connection tips
• Keep all power cords away from all signal cables to prevent
humming from induced noise.
• Choose reliable signal cables cords (Earthquake Sound also
specializes in high-performance RCA cables and patches).
• All speaker wires that are ran through the walls should be twisted
type to reduce potential hum noise pick up.
• Label both ends of all wires with the corresponding room
location.
• It is best to use a grounded electrical outlet to power the
amplifier. Lack of input ground reference could be unsafe.
Consult with your electrical contractor about proper grounding.

Powering Your SWAT 2.4
Connection of power to Transmitter: the Transmitters are strictly tested before delivery to ensure the
•
highest quality possible. They are matched and ready to work as soon as they are plugged in and
switched on. You can connect the 110/220 Power Supply to the Transmitter and connect the other end to
a wall outlet. Or, you can use a USB cable and power it through your computer. The LED will remain on,
indicating that the Transmitter is working properly.
• Connection of power to Receiver: the Receivers are strictly tested before delivery to ensure the
highest quality possible. The Receiver has the same powering options as the Transmitter. When
powered and switched on, the LED light remains off, indicating that the receiver is working properly. If the
LED light is on, the Receiver cannot receive the signal or there is a working problem.
• Audio Connection: Turn to the next page for instructions on connecting your SWAT 2.4 to audio devices.
Pairing the Transmitter to Receiver
Before SWAT 2.4 is shipped, the Transmitter and the Receiver are already paired. However, here are
instructions for point to point pairing in the event that they are not paired or they lose connection. There
are also instructions for point to mass pairing (connecting one Transmitter to multiple Receivers).
Point to Point Pairing (Connecting 1 Transmitter to 1 Receiver)
• Press and hold down the CH buttons on both the Transmitter and the Receiver at the same time for more
than 3 seconds, until the LED lights are on. The Transmitter light will flicker for 5 seconds indicating that
the Transmitter and the Receiver are pairing.
Note: If successfully paired, the LED light on the Transmitter will flicker 5 times and the Receiver will
flicker 3 times. Normally the LED light will then turn off if the receiver is successfully paired with the
transmitter.
Point to Mass Pairing (Connecting 1 Transmitter to multiple Receivers)
• Connecting the Transmitter: Press and hold down the CH button for more than 3 seconds until the
LED light turns on, then release the button. The light will flicker for 5 seconds, within these 5 seconds
press and hold the CH button again. The LED light will keep flickering indicating that the Transmitter is in
mass-pairing mode.
Note: DO NOT release the CH button until the Transmitter has paired with all of the Receivers.
• Connecting the Receivers: While holding down the CH button on the Transmitter, press down the CH
button on the Receiver for more than 3 seconds. After you release the button, the light will flicker for 5
seconds indicating it is finding the Transmitter. Once the Receiver has paired with the Transmitter, the
LED light will flicker 3 times. When it is done pairing, the LED light will turn off. Repeat this process for
each of the Receivers. Once all the Receivers have been paired, release the Transmitter CH button.
Channel Changing
The SWAT 2.4’s state of the art technology includes an effective anti-jamming feature, which is able to fully
shield the interference from common cordless telephones, mobile phones, walkie-talkie/two-way radios,
and many other wireless facilities, leaving clear, high-fidelity, wireless audio frequency. However, in the
rare cases when the wireless Transmitter tries to broadcast through the wrong channel, you can simply
press the CH button and select a different channel. This is why the SWAT 2.4 offers 20 channels, more
than any other transceiver on the market. It also has a channel tracking mode, in which the Receiver will
automatically find the Transmitter's channel after it is changed.
• To manually change the channel, the Transmitter and the Receiver channels must be changed
simultaneously.
• To automatically change the channel, pair the Transmitter and Receiver as described earlier (hold down
the CH button on each unit at the same time for 3 seconds, until the LED light flickers).
