Important safety instructions
◼READ, KEEP and HEED these instructions.
◼CLEAN ONLY with dry cloth.
◼DO NOT block any ventilation openings. Allow sufficient distances for adequate ventilation
and install in accordance with the manufacturer’s instructions.
◼DO NOT install or place near any heat sources such as open flames, radiators, heat registers,

⚫Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface
cables when connecting to computer or peripheral devices).
FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment
should be installed and operated with a minimum distance of 0.5 centimeters between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
The antennas used for this transmitter must be installed to provide a separation distance of at least 0.5 cm from all persons
and must not be co-located or operating in conjunction with any other antenna or transmitter.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1).This device may not cause harmful interference, and
(2).This device must accept any interference received, including interference that may cause undesired operation

Important usage instructions
◼To cope with the complicated 2.4GHz wireless environment, the line-of-sight distance
between the microphone and the receiver should be shortened to ensure that the signal is not
blocked.
◼When one receiver is used with two microphones, it is recommended that the microphones be
set to A-SCAN mode. (Please refer to P13)
◼When two receivers are used with four microphones, the microphones should be set in F-
CH01~F-CH04 modes respectively and the modes cannot be repeated. (Please refer to P13)
◼The A-SCAN mode and F-CH01~F-CH04 mode cannot be mixed in the same system.
◼When the system encounters interference or signal interruption, try the following:
The microphone enters the A-SCAN function page and scans to search for the best
available channel.
The receiver should be kept at least 5 meters away from other WiFi, Bluetooth or 2.4GHz
devices in use.
Keep the distance between the microphone and the receiver at least 2 meters.

Instructions
Antenna installation
Install supplied 2.4GHz receiver SMA antenna A and B at SMA connectors on the front panel.
Please make sure the antennas being firmly tightened otherwise the reception quality might be
affected.

Receiver placement
1. The receiver should be at least 1m above the ground and
1m away from a wall or metal surface to minimize
reflections.
2. The transmitter should also be at least 1m away from a
wall or metal surface to minimize reflections.
3. The transmitter should also be at least 1m away from the
receiver. Keep antennas away from noise source such as
motors, automobiles, neon light as well as large metal
objects.
4. The receiver should be at least 5m away from 2.4GHz wifi
or other 2.4GHz transmitting devices.
5. Power voltage should not below 12V DC or above 15V DC. Deficient current causes unstable
operating voltage or malfunction and over current shortens the product life and possibly
damages circuits.
Rack mounting
The receiver can be cabinet-mounted by either one or two units. If only one receiver is to be
mounted, an optional kit is available and it's installed as shown in Fig 1. If two receivers are to
be mounted, they can be assembled by another kit and installed as shown in Fig 2.

Equalizer setting
Equalizer adjustment is actually used to increase or reduce the high/mid/low frequency
component of the speaker's restored sound. It is so-called raising or attenuating treble/bass via
frequency-specific volume controls to improve human voices or make musical instruments’
sound more prominent. According to the scale values on the screen, UP button is to increase
and boost and DOWN button to decrease and attenuate.
Adjust the level of high frequency (Treble), mid frequency (Mid), and low frequency (Bass)
respectively. All signals have been balanced by the high and low sounds after entering the
receiver so it is not necessary to adjust the equalizer during the output to the speaker. It is
recommended to maintain the value of BASS, MID and TREBLE at 0 dB.

Audio output connection
INDIVIDUAL balanced output
MIXED unbalanced output
XLR connector provides
balanced audio output signal
from this jack to the
mixer/amplifier. Use an audio
output cable with “XLR” or
“Cannon” connector, connect
one end to the balanced
output jack of the receiver,
and the other end to the “MIC
IN” jack of the mixer/
amplifier. (Fig 3)
¼” PHONE PLUG connector provides unbalanced audio
output signal from this jack to the mixer/amplifier. Use an
audio output cable with ¼” PHONE PLUG connectors.
Connect one end from the unbalanced output jack of the
receiver, and the other end to the “LINE IN” or “MIC IN”jack
of the mixer/ amplifier.
Level switch setting
◼When connecting to the LINE /AUX IN of a mixer/amplifier,
switch to “LINE” position (Fig 4). DO NOT use the “MIC”
position as they may not deliver a sufficient high output
level.
◼When connecting to the “MIC IN” jack of a mixer/amplifier,
switch to “MIC” position (Fig 5). Overload distortion may
occur at the wrong level position.
