Rechargeable Batteries

Rechargeable lead-acid batteries are the same type used in automobiles. As with your car battery, how you use this battery has a significant impact on its lifespan. With proper use and treatment, a lead-acid battery can last for years. Here are some recommendations for getting the longest life from the internal battery.

General
Fully charge the battery before using the speaker.

Usage
Charge the battery completely after each use.

Storage
For best product longevity, do not store at exceedingly hot (greater than 90 °F / 32 °C) or exceedingly cold (less than 32 °F / 0 °C) temperatures.
It is acceptable to leave your speaker plugged in. This will not overcharge the battery.
If you leave the battery level low and do not charge it for 6 months, it may permanently lose capacity.

Repair
If the battery fails to charge, contact Alto Professional at altoprofessional.com.

Disposal
Bring the unit to a recycling center or dispose of in accordance with local ordinances.

Alto Professional and inMusic are not responsible for the misuse of its products caused by avoiding compliance with inspection and maintenance procedures. Please also refer to the included safety and warranty manual for more information.

Caution: To reduce the risk of electric shock, do not connect Uber to a power outlet while the grille is removed.

Stand-Mounting

Always install loudspeakers in accordance with applicable electrical and building codes.
Install the loudspeaker according to its maximum weight. Check the specifications of your stand or pole to ensure it can support the loudspeaker’s weight. Also, observe all safety precautions specified by the manufacturer.
Do not mount multiple loudspeakers on the same stand or pole.
Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully extend the legs of tripod-style stands, and ensure its legs do not present a trip hazard.
Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn, damaged, or missing parts.
Always be cautious in windy, outdoor conditions. You may need to place additional weight (e.g., sandbags) on stand’s base to improve stability. Do not attach banners or similar items to any part of a loudspeaker system. Such attachments could act as a sail and topple the system.
Unless you are confident that you can handle the loudspeaker’s weight, ask another person to help you lift it onto the stand or pole.
Make sure your cables are out of the way of performers, production crew, and audience so they will not trip over them, pulling the loudspeaker off the stand or pole.

Sound Level

Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S. Occupational Safety and Health Administration (OSHA) has specified permissible exposures to certain noise levels. According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in hearing loss. When using equipment capable of generating high SPL, use hearing protection while such equipment is under operation.

Features

Front Panel

Combo Inputs with Volume Control: Use a standard 1/4″ (6.35 mm) TRS or XLR cable (not included) to connect your sound source to each input. Use the Volume knob to adjust the level of each one.
Line/Mic Switch: Use this switch to set the Input to accept either a Line-level or Mic-level sound source.
Note: When using an instrument with passive pickups, set the switch to the Mic setting. When using an instrument with active pickups, set the switch to the Line setting.
Bluetooth® : The Bluetooth LED will be lit when a device is paired to Uber. This LED will not be lit when Uber is first powered on (unless it was previously paired with a device). Press the Bluetooth button to disconnect a paired Bluetooth device.
Auxiliary Input with Volume Control: This stereo 1/8” (3.5 mm) input can be used to connect a CD player, MP3 player, or other audio source. The Volume control adjusts auxiliary input and Bluetooth volume.
Master Volume Control: This adjusts the loudspeaker’s main mix volume, which includes Instrument/Microphone Inputs, Auxiliary Input, and the audio of a paired Bluetooth device.
Line Out: Use a standard 1/4″ (6.35 mm) TRS cable ( not included ) to connect this output to the input of another loudspeaker. The Line Out is post-Master Volume Control.
USB Charging Port: Connect your device’s charge cable here to charge it. USB charging only functions when the unit’s power is turned on.
Note: To charge smartphones and tablets faster, put the device’s screen to sleep.
Power Switch: Use this switch to power the loudspeaker on or off. Make sure all Volume knobs are set to “zero” before powering it on. When the loudspeaker is powered on, the Power LED above it will be lit.
Charge Indicator: This LED will illuminate when Uber is connected to AC power to indicate it is charging. Once charging is complete, the LED will go off.
Battery Level Indicator: While the unit is powered on, these four lights indicate the power left in the battery. Battery life varies based on volume and usage.
Power Cable Input (rear panel): Insert the included power cable here to charge the unit. Please note that when the power cable is connected, the battery will still charge while the unit is in use.
NFC (Near-Field Communication) (top panel): Touch and briefly hold your supported and enabled device to the NFC logo to pair the device. See Pairing a Bluetooth Device Using NFC for more information.

Operation

Pairing a Bluetooth® Device

Turn on your Bluetooth device.
Turn on Uber using the power switch. If you have previously connected to another Bluetooth device, Uber will reconnect.
Navigate to your Bluetooth device’s setup screen, find Uber and connect.
Note: If your device requires a passcode or PIN, enter 0000.
The Bluetooth LED will light up solid when it is “paired.”
If your Bluetooth device is not able to connect to Uber, press the Bluetooth button on Uber to break previous Bluetooth connections and reset the Bluetooth module.
Start playback from your Bluetooth device.
To disconnect a connected Bluetooth device and connect to another Bluetooth device, press the Bluetooth button. Repeat Step 3.
Note: If you experience trouble connecting or playing music, update your device’s OS.

Pairing a Bluetooth Device Using NFC

NFC (near-field communication) allows data exchange from devices, such as pairing, by gently bumping them together. Check in your device’s manual to see if this feature is supported.

To use NFC to pair with Uber:

In order to use NFC, your device must be turned on and unlocked.
Enter your device’s Settings menu and check that NFC is turned On (one-time step).
Power on Uber.
Touch and briefly hold your device to the NFC logo located on Uber’s top panel.
Follow the pairing instructions that appear on your phone. If a passcode is required, enter “ 0000 ”.
To unpair, gently bump your device against the NFC logo.

Using the Aux Input

Connect your smartphone, MP3 player, or similar device to the Aux Input. Adjust the output volume on your source device and then adjust the overall volume using the Aux Input Volume Control on Uber.

Troubleshooting

If the sound is distorted: Try lowering the volume control of your sound source, musical instrument, or microphone. Also, try to reduce the overall volume of Uber using the Master Volume knob.

If there is too much bass: Try adjusting the tone or EQ control on your sound source to lower the bass level. This will allow you to play the music louder before clipping (distortion) occurs.

If there is a high-pitched whistling noise when using microphones: This is probably feedback. Point the microphone away from the speaker.

If you can’t hear the microphone over the music volume: Turn down the music volume from your source.

If you can’t hear your instrument: Check the setting of the Line/Mic switch. If you are using an instrument with passive pickups, set the switch to the Mic setting.

If you can’t play music from a flash drive: The USB port is only for charging USB devices.

The Maximum Permissible Exposure (MPE) level has been calculated based on a distance of d=20 cm between the device and the human body. To maintain compliance with RF exposure requirement, use product that maintain a 20 cm distance between the device and human body.
