Additonal safety advice

• Never force or push any objects into any of the receptacles or openings of the Loudspeaker other than the correct connector.

• Do not power NAXOS Loudspeakers from a generator or inverter.

• High powered loudspeaker systems can produce excessive sound levels which can cause permanent hearing damage or hearing loss. Exposure to such sound levels at close proximity or at levels which feel uncomfortable for extended periods should be avoided.

• Before connecting AC power or any external equipment to the loudspeaker, ensure that all controls
  are set to their minimum positions.

• NAXOS Series loudspeakers are capable of reproducing considerable bass (low frequencies) which can cause gradual movement or creeping of the speaker cabinet at high volume levels and could result in the loudspeaker falling. If used on a raised, low friction surface such as a stage or table, we strongly recommend that the loudspeaker cabinet is placed on a non-slip mat or secured to prevent such movement.

Remove the electric plug from the outlet when the devices is not to be used for extend periods of time, or during electrical storms. When removing the electric plug from the device or an outlet, always hold the plug itself and not the cord. Pulling by the cord can damage it. When transporting or moving the device, always use two or more people. Attempting to lift the device by yourself may damage your back, result in other injury, or cause damage to the device itself. Before moving the device, remove all connected cables. When setting up the device, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Do not use the device in a confined, poorly ventilated location. Make sure that there is adequate space between the mixer and speaker cabinet, make sure to allow adequate space between the can result in overheating, possibly causing damage to the device(s), or even fire. so could result in damage or personal injury. Avoid setting all equaliser controls to their maximum. Doing so may cause feedback and may damage the speakers. Do not expose the device to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel cabinet deformation or damage to the internal components. Do not place the device in an unstable position where it might accidentally fall over.

Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electronic devices. Doing so may result in noise, both in the loudspeaker itself and in the TV or radio next to it. When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage. When turning the power off, the device should be turned off FIRST for the same reason. Do not insert your fingers or hands in any gaps or openings on the device (vents, ports, etc.). Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device (vents, ports, etc.). If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified service personnel. Do not use the device for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician immediately. Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors.

Interference From Cell Phone
Using a cell phone near the speaker system can induce noise. If this occurs, move the cell phone further away from the speaker system. Air blowing out of the bass reflex ports is normal with heavy bass content. Always turn the power off when the device is not in use. The performance of components with moving contacts, such as switches, volume controls and connectors can deteriorate over time. Consult qualified service personnel about replacingg defective parts.

Connecting and Using NAXOS Loudspeakers

First things first!

1. Before connecting the power or signal cables, mount or position your NAXOSLoudspeaker where you intend to use or try it, do not carry it with any cables connected.

2. Set the MIC/LINE and BT/AUX input levels to minimum, the Master EQ controls to their mid positions, then connect the AC power and switch on the Loudspeaker.
   Note : To prevent “thump” at power-on,NAXOSspeakers use a Soft Start Power Supply incorporating a two second delay between switch-on and any indication of power.

3. Connect your source or host device as follows

Connecting a Dynamic Microphone or Wireless Microphone System:

1. Note: The MIC/LINE inputs of your NAXOS Loudspeaker will be set to LINE mode from new and need to be switched to MIC mode.
2. Using a small screwdriver or similar implement, with care, switch your chosen MlC/LINE1 or MICILINE2 input to its “IN” position by gently pushing the recessed Line/Mic button. This will set the input to MIC mode.
3. Connect your microphone or wireless microphone receiver via the chosen TRS jack or XLR input of your NAXOS Loudspeaker.
4. Ensure that your wired microphone or wireless microphone system is switched on and that its volume control is not set to minimum.
5. Speak into the microphone while slowly increasing the level control of the corresponding MIC/ LINE NAXOS input until you hear your voice in the speaker.
6. Always keep the microphone away from the speaker when using increased levels to avoid acoustic feedback squealing/howling.

Connecting a Sound Mixer:

1. The wired inputs of your NAXOS Loudspeaker will be set to LINE mode from new, therefore it should be ready for connection to a sound mixer. But this can be confirmed as described in the previous paragraph if required.
2. Connect your sound mixer to the Loudspeaker via its TRS jack or XLR inputs. Note: for stereo reproduction from a stereo source, you will require two matching BX Loudspeakers connected as one for each of the Left and Right stereo channels.
3.  Ensure that your chosen sound mixer is outputting a signal and that its volume is not set to minimum.
4. Slowly increase the level control of the corresponding MIC/LINE inputs. You should hear music from the Loudspeaker.

Connecting a Laptop, Tablet or Smartphone by Cable:

1. Using the relevant cable, such devices can be connected by wire to any of the NAXOS Loudspeaker’s inputs, but the most common way is to use a simple and readily available 3.5mm mini jack to mini jack stereo cable.
2. Connect one end of the mini jack cable to your desired device and the other end to the Aux input of the NAXOS Loudspeaker.
3. After ensuring that there is music playing on your device and that its volume is not set to minimum, slowly increase the BT/AUX, you should hear music from the Loudspeaker.

Connecting via Bluetooth:

1. Ensure that the Bluetooth on your chosen host device is turned on.
2. On your NAXOS Loudspeaker, long press the Pair button for 2 seconds, the Pair blue LED should begin to flash rapidly.
3. Refresh the Bluetooth of your host device and look for ” NAXOS 10A DSP,NAXOS 12A DSP ,NAXOS 15A DSP” relevant to your NAXOS model, then pair and connect with it.
4. Once the connection has been established, the Pair blue LED of the Loudspeaker will remain lit continuously to indicate a successful connection.
5. Ensure that your host device is playing music and that its volume is not set to minimum.
6. When slowly increasing the level of the BT/AUX control of the Loudspeaker you should hear your source musiC.

TWS (True Wireless Stereo) Connectivity

When connecting your host device to a single NAXOS loudspeaker using Bluetooth, both the left andright channels of a stereo signal will be combined and played through the single Loudspeaker. However, using two NAXOS Loudspeakers, the TWS function allows them both to be connected wirelessly as a stereo pair to the same host Bluetooth device as described below. This assumes that both Loudspeakers have been connected to AC power and are switched on. Note: The NAXOS Loudspeaker first paired to your host device will become the Left stereo speaker.

1. Pair and connect the first NAXOS Loudspeaker to your host device as described in the previous paragraph (connecting via Bluetooth). This will become the Left speaker.
2. Switch on the second NAXOS Loudspeaker and set the BTIAUX level to minimum.
3. Long press the Pair button on the second Loudspeaker for 2 seconds, the Pair blue LED should begin to flash rapidly.
4. On both Loudspeakers, press the TWS button once, their TWS green LED’s should begin to flash rapidly.
5.  On the first Loudspeaker, press the TwS button once more, the TWS green LED’s on bothLoudspeakers should remain lit constantly to indicate a successful TWS connection. The Pair blue LED of the second speaker should no longer be lit.
6. Ensure that your host Bluetooth device is playing music and that its volume is not set to minimum.
7. When slowly increasing the level of the BT/AUX control of the Loudspeakers you should hear music from them both. The volume of both speakers can be controlled by your host device.

DSP Modes
Your NAXOS Series Loudspeaker incorporates a DSP (Digital Signal Processing) system which has 4 preset modes of equalisation (tone control) to suit your intended mode of operation. Pressing the Curve button on the DSP Parameter Control area of the panel will scroll through the available modes as follows:-

• Standard- For general music or mixed voice/music reproduction use.
• Vocal Boost- When using only microphones for public address.
• Live For live band music performances.
• Stage Monitor When using the loudspeaker horizontally in stage monitor applications

Bass and Treble adjustment
The Bass and Treble controls are provided for additional adjustment of the equalisation where required and are effective using all inputs of the speaker. The Line Out XLR connection is not affected by the Bass and Treble settings.

Note: When increasing the desired volume level, it is possible to reach an overload situation sooner as a result of a higher Bass setting or excessive bass content in music. This can be improved by reducing the Bass level control of your NAXOS Loudspeaker.

Linking Speakers by Wire

NAXOS Loudspeakers can be linked together by connecting the LINE OUT of one Loudspeaker (the master) to a MICILINE input of the next (the slave) using an XLR female to male or XLR female to jack cable. Several speakers can be connected together in this way if required.

Note: When linking by wire, the MIC/LINE input of the slave speaker must be set to LINE mode as described previously. Also, this configuration will not enable true stereo operation.

Overload Warning

NAXOS Loudspeakers incorporate some degree of overload protection, but over driving is still possible and can cause severe damage to the Loudspeaker. Such damage is not covered by warranty and correct use remains the responsibility of the user The SIG/LIMIT LED on the upper right of the amplifier panel will light or may flicker Green toindicate the presence of an input signal during normal use. However, should it light RED, this is an indication of excessive input signal or that the Loudspeaker is being over driven. In this case, the signal level from the connected device and/or the respective MIC/LINE or BT/AUX level must immediately be reduced to avoid damage to the Loudspeaker.

Transporting, Mounting and Installing BX Loudspeakers
The NAXos 10A DSP Loudspeaker has a top carrying handle and the NAXOS 12A DSP and NAXOS 15A DSP models have side and top carrying handles.For safety they should only be carried using these handles. The cabinets are robust but they must be lifted, handled and placed onto hard surfaces with care. All models can be mounted onto a standard 35mm pole using the integral receptacle in the cabinet base with hand locking hand bolt.Two M6 points are provided in the top of the NAXOS 10A DSP cabinet and M8’s in the top and bottom of the NAXOS 12A DSP and NAXOS 15A DSP. AIl fixing points are covered by easily removable cosmetic caps during production.

Care and Maintenance

No adjustment or maintenance of NAXOS Loudspeakers is necessary and cleaning should only be done using a dry, non-abrasive cloth or dry dusting brush.

Warranty

NAXOS Series Loudspeakers are warranted in the EU only for one year from the date of supply or delivery against faulty parts or manufacturing defects. The warranty excludes electrical or mechanical faults or damage as a result of over driving by excessive input signal, excessive AC voltage, abuse, misuse, or failure to observe the operating guidelines detailed in this manual.
