Input Wiring
Safety Overview
• RCA Connection:
• Common Audio Connections supplied typically for Mixers, and Compact Discs.
• XLR Connections:
• XLR is the Industry Standard Connectors for Microphones;
robust and relatively simple to install. There are several ways to connect to
the system.
• Balanced Operation:
• Pin 1 Connection to the Grid (Signal Ground)
• Pin 2 Connection to + signal (Live)
• Pin 3 Connection to - signal (Return)
• The Pin Number is identied on the XLR Connector. XLR Connections are
relatively easy to connect. X = Ground (Pin 1), L = Live (Pin 2)
and R = Return (Pin 3)
• Connect Jumper (XLR Plug) by the following order:
• Terminal (-2, Left) with (-1, Right) = Negative
• Terminal (+2, Top) with (+1, Bottom) = Positive
Before connecting the speaker, make sure the system is off, and the controls are on
the minimum level. If not set to minimum setting, the probability of
damaging internal components is extremely likely.
CAUTION:
Do not place the microphone against the speaker, it can cause feedback echo and it
will damage the system.
— Do not overheat the system
— Do not expose to direct heat for long periods of time
— Verify that the voltage switch is set to the corresponding voltage in your
country. (110 Volts default setting)
— When not in use, unplug the power cord, or switch off
— Use appropriate mounting brackets to avoid bodily harm
— Protect from any water or liquids
— Never try to repair unit yourself
— Keep out of reach of children, as there is high voltage and could
cause injuries.

Important Safety
- Do not use this system near water
- Clean with a dry cloth
- Do not block any ventilation opening
- Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades with one wider than the other. A grounding-
type plug has two blades and a third grounding prong. The wide blade or the
third prong is provided for your safety. If the provided plug does not t into your
outlet, consult an electrician for replacement of the obsolete outlet.
- Protect the power cord from being walked on or pinched, particularly at plugs.
- Unplug this unit during lightning storms or when unused for long periods of time.
- Do not expose this equipment to dripping or splashing and ensure that no objects
lled with liquids, such as vases, are placed on the equipment.
- The speaker system contain a 36 mm receptacle cup to allow mounting on
tripod stands.
- Check the stand or pole specication to be certain the device is designed to support
the weight of the speaker.
- Do not attempt to place more than one speaker system on a stand or pole.
- Always be cautious in windy, outdoor conditions. It may be necessary to place
additional weight (i.e. sandbags) on the base of the stand to improve stability.
- Be cautious of where you place the speaker system, certain frequencies will cause
the unit to vibrate the cabinet and move from it’s original position.

Operation
Pairing a Bluetooth Device
The Alphasonik Speaker includes Bluetooth functionality, and as such, is congured
to automatically launch in “Discoverable Mode” upon launching the Bluetooth mode,
to make the device itself detectable by other Bluetooth-Enabled devices, such as a
mobile phone or tablet.
When in Discoverable mode, look for the device “M912BT and/or M915BT”, then
connect. No PIN is required to initially pair your device with the speaker.
Once your device indicates a “Connected” status with the speaker, you may now begin
streaming audio from your device.
You can also control the Playback functions by using your device.
To pair with another device, you must rst “Un-pair” the last connected device. You can
also pair with a new device at startup.
Powering the Unit On
• Connect the power connector to the corresponding power input.
• Turn the VOLUME controls down and turn the POWER switch to the ON position.
• This unit may be connected to another active Alphasonik speaker so that
multiple speakers can be connected and playing at the same time from
a single source. (Connect the XLR cable to the XLR output of the main
speaker and connect the other end of the XLR cable to the secondary
speaker’s XLR input. *XLR cables is required - (not included & sold separately)
• Switch-On the audio source, then the unit
