MULTI-PURPOSE FEATURE
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 amplier 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.
Above is a stereo connection of the speakers to the amplier.
Below is a parallel connection of the speakers to the amplier.
When connecting multiple speakers in parallel, be sure to
follow the amplier’s specications in relation to the
minimum allowed impedance. Most ampliers allow for a
minimum 4Ω impedance which corresponds to two Pro Series
speakers connected in parallel.

INSTALLATION
GENERAL CONSIDERATIONS
The NEXT Audiocom Pro Series speakers are ready to be
installed in a variety of dierent 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 (see the instructions on page 6).
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 nal 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 ange and remove it. Install the new
screw ange 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.
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.

TROUBLESHOOTING
PASSIVE VERSION
Problem: No sound coming from the speaker
Action to Solution:
- Check volume levels on the amplier and signal sources and
the connections between them. If your amplier 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 amplier. 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 amplier, is connected to the 1+ on the NL4 and
the “-“ marked on the amplier 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 reections 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.
