IMPORTANT SAFETY INSTRUCTIONS
Danger
Exposure to extremely high noise levels may cause a
permanent hearing loss. Individuals vary considerably to noise
induced hearing loss but nearly everyone will lose some
hearing if exposed to sufficiently intense noise for a sufficient
time.
The U.S. Government's Occupational Safety and Health
Administration (OSHA) has specified the following
permissible noise level exposures:
DURATION PER DAY (HOURS) 8 6 4 3 2 1
SOUND LEVEL (dB) 90 93 95 97 100 103
According to OSHA, any exposure in the above permissible
limits could result in some hearing loss. Earplugs or protectors
in the ear canal or over the ears must be worn when operating
this amplification system in order to prevent a permanent
hearing loss. If exposure in excess of the limits as put forth
above, to insure against potentially harmful exposure to high
sound pressure levels, it is recommended that all persons
exposed to equipment capable of inducing high sound pressure
levels, such as this amplification system, be protected by
hearing protectors while this unit is in operation.

1. AUX IN: Use this stereo input to connect an external audio device such as an MP3, CD player or computer for playback. Note: Right
and Left channels are summed to mono on this input.
2. MIC Input: This XLR input is designed for low-impedance microphones or equipment that has a mic-level, balanced output.
Note: This input sends 9-volt phantom power. This is used to provide power to condenser microphones. Phantom power will not
damage any dynamic or non-condenser microphone.
3. LINE Inputs: These ¼-inch unbalanced inputs may be used to connect high-impedance microphones, keyboards, drum
machines and other audio devices.
4. Volume: Use these controls to adjust the volume level of each channel and the relative balance between them.
Note: This control affects the level of the OUT jack.
5. Low: Determines the emphasis of bass frequencies. Turning this knob clockwise creates a deeper, warmer tone. If you
need a brighter sound, reduce the bass by turning counterclockwise.
6. High: Turned clockwise, this control accents treble frequencies to produce clearer, crisper sound. Turn counterclockwise to make the
sound softer and less bright.
7. Master Volume: Controls the overall volume of the LP1440.
Note: Does not affect the level of the OUT jack.
8. IN: This balanced XLR Jack is a line level input that bypasses the preamp controls. Use a standard XLR mic cable to connect a
balanced line level output to be amplied through the LP1440. This signal is summed with the other inputs, and that signal can be
controlled by the master volume.
Note: The shield connection (pin 1) on this jack is connected to chassis ground. It is not lifted.
9. OUT: This balanced XLR Jack is a line level output of all the input signals, including the IN jack. It is used to send your signal to an
external mixer or PA system. Use the Channel Volume controls to get the right balance for the mix of the channels. The IN jack’s signal
will be passed directly to the OUT jack. The Master Volume controls the loudness of the mix through the cajon, not the OUT jack.
Note: The shield connection (pin 1) on this jack does not connect to chassis ground. It is lifted.
10. Bluetooth LED: Indicates that a Bluetooth equipped device has successfully paired with the LP1440.

LP1440:
BLUETOOTH PAIRING INSTRUCTIONS
To connect your Bluetooth device to the LP1440 Bluetooth receiver for the rst time, navigate to the Bluetooth settings menu on your
Bluetooth enabled device. Ensure that Bluetooth is enabled and your LP1440 is powered on.
Perform a scan for available devices. Select and pair to the LP1440 in the list of available devices.
Enter 0000 for the passcode if prompted. Once paired, a connection can be established. Depending on the device, future
connections may be established automatically when a previously paired Bluetooth device is in range of the LP1440 Bluetooth
receiver.
The Bluetooth receiver in the LP1440 is an A2DP device and will work with other A2DP compatible Bluetooth devices including most
smart phones. Additional hardware and/or driver software may be required for computers with integrated Bluetooth adaptors due to a
lack of support for A2DP devices by some operating systems.
A2DP protocol only allows for one to one device connections. Therefore, only one Bluetooth device can be connected to the LP1440
at a time. Similarly, a Bluetooth device can only be connected to one LP1440 at one time. Plugging a 1/8” connector into the AUX
jack disables the LP1440 Bluetooth receiver.
11. CHARGING LED: LED indicates “rapid charge” stage and will turn off when unit enters “oat charge” stage. It is recommended to
charge for 12 hours after use. Battery charges even if the unit is ON under normal volume conditions. When played loud, the battery
will stop charging to allow higher power demand. To resume charging, uplug AC power cord, then reconnect after 10 seconds.
12. BATTERY LEVEL INDICATOR: During use, the BATTERY LEVEL indicator LED’s show the remaining battery power. When the
red light on the left is on, turn off the unit and recharge to avoid excessive battery drain.
13. AC Power Cord Receptacle: Insert the AC cord rmly into the AC receptacle. Power circuit is on whenever AC cable is
connected to unit and plugged into wall. Be sure to use the cable provided with your LP1440. The power cord can be removed for
storage or replacement if damaged.
Note: Replace the AC cord if its protective jacket is damaged or ground pin is damaged or removed.
14. Power: This switch activates power to the battery powered product.
Note: Power is supplied to the unit for charging even if Power switch is off.
BATTERY:
IT IS RECOMMENDED THAT THE BATTERY BE RECHARGED AFTER USE TO PROLONG THE BATTERY LIFE.
FREQUENT CHARGING WILL NOT HARM YOUR BATTERY, AND WILL ENSURE THAT THE BATTERY IS FULLY
CHARGED AND READY FOR ITS NEXT USE. STORING BATTERY NOT FULLY CHARGED WILL SHORTEN
BATTERY LIFE.
-Always charge for 12 full hours after heavy use.
-The battery does not need to be fully discharged before recharging.
-For best results, recharge the unit as soon as possible after use.
-It is best if battery is fully charged before storing for long periods of time. Store in a cool, dry place.
Additional Features: Here are a few additional features designed to prolong the life of your Battery Powered PA.
Standby Mode: Power amplier goes into Standby Mode after 20 minutes of non-use with POWER ON to extend battery life. Power
Amp turns back on 1/2 second after input signal is detected.
Protection Mode: When driven to extreme distorted levels the amplier will go into Protection Mode (Amplier will momentarily mute
audio to protect speakers and electronics).
-It is recommended to stop using the unit under battery power when red Battery Level LED is on.
