CONNECTIONS

PASSIVE VERSION

The NEXT Audiocom Pro Series speakers, in the passive version, have a nominal impedance of 8Ω. Use a Neutrik NL4 to connect the amplifier to the speaker. On the speaker side connect the wires to 1+/1-. To avoid speaker damage, be sure to deliver not more than 500W to Pro12 and 700W to Pro15.

Connections Induction

Above is a stereo connection of the speakers to the amplifier.
Below is a parallel connection of the speakers to the amplifier.

Connections Induction

When connecting multiple speakers in parallel, be sure to follow the amplifier’s specifications in relation to the minimum allowed impedance. Most amplifiers allow for a minimum 4Ω impedance which corresponds to two Pro Series speakers connected in parallel.

ACTIVE VERSION

You can connect any instrument, microphone, CD Player or audio mixer to the active Pro Series input. The Pro speakers can be connected between each other using the “Mix Out” connector. An active external subwoofer can be added to extend the system frequency response.

You can use your mobile device to play wireless music, using the bluetooth technology, to one Pro speaker. The Pro speakers can be connected between each other using the “Mix Out” connector. An active external subwoofer can be added to extend the system frequency response connecting it as the example above.

PRESETS

PRESET LIST

FLAT – Speaker’s Flat Response – use this preset in live performances for clarity of voice and instruments.
HF BOOST – Speaker’s EQ for Long Distances – use this preset when long throw is needed or when used on very absorbent room (dead room).
MUSIC – Speaker’s EQ for Music Reproduction – use this preset for recorded music playback and electronic dance music applications.
WALL – Speaker’s EQ for Wall Applications – use this preset when the speaker is installed on the wall/ceiling using the wall bracket or U-Braket.
HPF 100Hz – Speaker’s High Pass Filter – use this preset to enable the HPF when using the speaker with a subwoofer. It will change the speaker’s high pass filter to 100Hz Linkwitz-Riley 24dB/oct.

PRESET CHANGING PROCEDURE

Press the Preset button once to change the preset among Flat, HF Boost, Music and Wall.
Press and hold the Preset button for 2 seconds to activate the High Pass Filter (100Hz). All the presets can be used with or without HPF.

BLUETOOTH PAIRING/UNPAIRING

To turn off the bluetooth on the speaker press and hold the pair button for 3 seconds.

HANDS-ON

INSTALLATION

GENERAL CONSIDERATIONS

The NEXT Audiocom Pro Series speakers are ready to be installed in a variety of different environments and applications. Each speaker can be hanged using 12 different hanging points, U-bracket (not included), wall bracket (not included and only available on Pro12 passive version) and ceiling bracket (not included and only available on Pro12).
Remember to rotate the HF horn when installing the Pro Series horizontally.

PREPARATION

Listed below is the hardware equipment needed to install the Pro Series.

U-BRACKET INSTALL INSTRUCTIONS

The U-Bracket has a total angle adjustment span of 115º.
Depending on the adjustment bolt used, the final speaker’s angle may vary.

(1) 100º to -15º
(2) 10º to -105º
(3) -80º to -195º

Remove the two bolts from the top of the speaker. Remove the bolts from the pole flange and remove it. Install the new screw flange provided with the u-bracket and fasten 3 bolts (the selected adjustment bolt will be fastened later on).
Mount the U-bracket at a designated location on the wall or ceiling (when mounted horizontally on the wall, the UP arrow must be pointing upwards). The screws are inserted into the holes provided on the bracket. Use the correct fasteners for the surface on which the bracket is to be mounted.
Insert the large (M8) bolts into the center threaded holes (speaker’s top and bottom). These should stay up just high enough so that the intended slot in the bracket can be hooked in.
Add the additional (small) safety/adjustment bolts and washers. This is placed in the rotation slot of the bracket. Do not totally fasten it.

Adjust the speaker angle and totally fasten the bolts.

WALL BRACKET INSTALL INSTRUCTIONS

A two-axis wall bracket can be used on the Pro12 passive speaker. The adjustment angle span will vary according to the selected pan and tilt angles. The maximum tilt angle is -30º.

Disassemble the wall bracket into the two main parts. Mount the bracket part at a designated location on the wall or ceiling. The screws are inserted into the holes provided on the bracket. Use the correct fasteners for the surface on which the bracket is to be mounted.
Remove the 6 bolts from the speaker’s back. Install the other part of the wall bracket.
Attach the speaker + wall bracket set into the already installed wall part. Insert the bolts but do not fully tighten them.
Adjust the pan and tilt angles and fully tighten the indicated bolts on the image.

SUSPENDED INSTALL INSTRUCTIONS

Remove the M8 bolts from the speaker where it’s pretended to hang from. Insert the M8 eye bolts and fully tighten them.
The speakers can be hanged vertically or horizontally. Always use a safety cable.

SUSPENDED INSTALL INSTRUCTIONS

HF HORN ROTATION PROCEDURE

To mantain the original vertical and horizontal coverage of the speaker (80º x 50º), when installing it horizontally, the high frequency horn must be rotated by 90º.
Remove the grill unscrewing the 4 screws on each side and pulling it out. Remove the 8 bolts from the horn, and pull it.
Rotate the horn by 90º and reinstall it. Place the grill back on.

HF HORN ROTATION PROCEDURE

SERVICE

TROUBLESHOOTING

PASSIVE VERSION

Problem: No sound coming from the speaker

Action to Solution:

Check volume levels on the amplifier and signal sources and the connections between them. If your amplifier has signal detection or measuring visuals, test if it is reacting to the signal source. If everything seems to be ok, connect another speaker known to be working to the amplifier. If it works, the wiring to the Pro Speaker may have problems.
Check that you have the correct pair of wires connected to the speakers you are trying to work with. Look for signs of damage if possible and check that the wires are correctly mounted on the connector and the connecter is correctly inserted on the speaker.

Problem: Little to no Bass

Action to Solution:

This happens most of the times when two or more speakers near each other, are wired out of polarity. In this case low frequencies will cancel each other acoustically. Check that the “+” on the amplifier, is connected to the 1+ on the NL4 and the “-“ marked on the amplifier terminal is connected to the 1- on the NL4.

ACTIVE VERSION

Problem: Buzzing, hissing or humming
Action to Solution:

If there is noise and no program material is playing, check your entire signal chain for the bad component. It can also be a matter of poor grounding or a ground loop. Check and correct the system grounding.

Problem: No sound from microphone on CH1
Action to Solution:

Check if the microphone is a condenser one. If it is, change to a dynamic one or use an external phantom power for condenser microphones.

Problem: Sound is distorting with PEAK led OFF
Action to Solution:

Reduce the level from the audio source, such as the mixer, increase the level on the input potentiometer.

Problem: Sound is distorting with PEAK led mostly ON
Action to Solution:

Reduce the level on the input or audio source

Problem : Too much low end when installed on wall or ceiling
Action to Solution:

Due to wall and/or ceiling reflections the bass response is increased. To linearize the low end, select the Wall preset.

Problem: Poor high frequency response
Action to Solution:

Probably the room is too absorbent or you are listening from a long distance. To increase the HF frequency response, select the HF Boost preset.

Problem : Poor low frequency response
Action to Solution:

Probably the High-Pass Filter is enabled. Press and hold the PRESET button for two seconds to disable de HPF.
