General Safety Instructions:
Loudspeakers produce a static magnetic eld even if they are not connected or are not in use. Therefore make
sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which
may be impaired or damaged by an external magnetic eld. Persons with cardiac pacemakers must maintain a
safe distance.
The minimum recommended safety clearance is 1 m.
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems
are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels
(from approx. 90 dB SPL) can cause hearing damage if people are exposed to it over a long period.
All connected cables must be laid in such a way that they cannot be crushed by objects and that nobody can
step on them! Replace damaged cables immediately and do not use them!
Use only accessory parts specied by Voice-Acoustic or original accessory parts from Voice-Acoustic. Check all
cabinets and accessories regularly for wear and replace them if necessary.
Do not set up the loudspeakers in places where they are permanently exposed to moisture, dust, dirt or direct
sunlight.
Care
Wipe the surface of loudspeakers only with a damp cloth and pure water. In case of heavy pollution, repeat the
above procedure several times if necessary. Do not use any chemical additives or aggressive detergents, as
these may harm and damage the surfaces.
Transport and storage
When transporting and storing the unit, it is important to ensure that the surface and front grill of the loudspe-
aker are not damaged. Moisture can penetrate through exposed wood surfaces and cause the wood to swell.
A bent or broken front grill will no longer adequately protect the sensitive speaker membranes. In addition,
appreciable dust deposits may considerably impair the functionality of a loudspeaker membrane. For this rea-
son, the loudspeakers should be transported and stored in a safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from Voice-Acoustic:
■Transport and rain cover for Modular-15, left and right (Art.-Nr. 501501100 und 501501200)
■Heavy duty ightcase for up to 2 x Modular-15 (Art.-Nr. 501503000)
Note: The original packaging is unsuitable as permanent storage and transport packaging!
Warranty
The warranty period is 24 months from date of delivery.
On our choice we will eliminate any lack of conformity with repair or with replacement of the faulty goods. The
place of performance for warranty services is Voice-Acoustic headquarters in Dörverden. In case of remedy of
defects, the buyer shall bear all costs resulting from transportation of the goods to Voice-Acoustic headquarters
in Dörverden.
The ordering party is not entitled to remedy the defect by itself or to organise a replacement and to charge
such activities to Voice-Acoustic. In case of self remedy by the ordering party the warranty given by Voice-
Acoustic becomes void.
Warranty doesn’t apply to parts of wear and tear, such as threaded points, such as threaded points, ying
tracks, tilting pole socket, rubber feet and the SpeakON®connectors.

Connections
The speaker has four loop-through Neutrik NL4 SpeakON®IN/OUT connectors. They use the 1+/1- connection
pins. Additional loudspeakers can be looped through via the second connector. The SpeakON®connectors at the
top and bottom of the loudspeaker are ideal for easy connection in monitor mode.

Introduction
Setup
The Modular-15 loudspeaker is designed for standing, vertical and horizontal operation. A variety of accessories
is available from Voice-Acoustic to securely attach the loudspeaker safely on tripods, distance rods or hanging
it from on trusses, ceilings and walls. Ensure that the loudspeakers are securely attached to prevent personal
injury and damage of property.
Connecting cables
When connecting the cables to the loudspeaker, ensure that the polarity (+/-) and pin assignment (1/2) is
correct. Incorrect connection results in a signicant change in the loudspeaker sound characteristics and may
damage the compression driver.
The two connection sockets on the back of the loudspeaker can be used to link multiple loudspeakers on a
single amplier. Note that parallel connection reduces the total impedance (Ω) seen by the amplier. The total
impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the
amplier.
Voice-Acoustic recommends to use the available 4 x 4 mm² Speakon cables for mobile use.
We recommend wiring the basses with at least 4 mm² in installations. The cables of the tops in installations
must be suciently dimensioned according to impedance, power and cable length.

Operation
The Modular-15 is exclusively intended for operation with Voice-Acoustic system electronics with internal DSP
controller: the HDSP power ampliers or powered by the free 800 W amplier channels of the self-powered sub-
woofers.
Make sure the appropriate preset has been selected before connecting the speaker to the system power amp or
self-powered subwoofer.
Using the wrong preset can damage parts of the loudspeaker.
Note: If the Modular-15 is not operated on the intended Voice-Acoustic system electronics, the manufactu-
rer‘s warranty for the loudspeaker expires!

Page 8 of 14Manual Modular-15 - 2018-07 EN
Forming a Array
For maximum exibility, the user can choose between two dierent beam angles, 60° x 40° or 90° x 60°. The
system ampliers of the HDSP series and the controller boards of the self-powered subwoofers contain specic
settings as presets for both beam angles.
Horns 60° x 40° or 90° x 60° are tted as standard. If you want to use two Modular-15 side by side in an array
(only with 60° x 40° horn), the horns must be rotated to avoid interference.
Note: The two loudspeakers are always joined together on the side walls with the largest contact surface. So
that the handles are inside and the bass ports outside.
Modular-15 in array with horn 60° x 40° (v x h) interference occurs

Horn 60° x 40° seen from the front
To turn the horn, remove the M6 x 40 mm countersunk head screws with which the horn is xed. Then turn the
horn with driver by 90° and screw it on again.

Easyy mechanics
Tool-less ight mechanism for clicking in and exact alignment of the
loudspeaker in the horizontal and vertical axis.
1. Pull the two locking bolts (A) upwards and let them engage by
turning them slightly.
2. Insert the Easyy mechanics into the ying track (B).
3. Slide the mechanics backwards as far as it will go.
4. Let the two locking bolts snap into the intended holes on the
ying track.
Note: Notice that the two locking pins (A) are engaged to pre-
vent the Easyy-Mechanics from slipping out.
Installations with Easyy mechanics
Installation with self-lock clamp (C) on trusses.
1. Mount the self-lock clamp to the Easyy mechanics using an
M10 threaded screw and lock nut.
2. Hang the clamp and holder into the mechanics using ball lock
bolts.
3. Hang the loudspeaker into the truss.
4. Adjust the inclination by xing the holder on the top hole rail
with the ball locking pin.
Installation with universal suspension arrangement for ight mecha-
nics (D) on high ceilings
1. Mount the universal suspension arrangement for ight mecha-
nics with an M10 threaded screw and lock nut to the mounting
of the Easyy mechanics.
2. Hang the suspension device and holder into the mechanics
using ball locking bolts.
3. Hang the loudspeaker into the installed chains.
4. Adjust the inclination by xing the holder on the top hole rail
with the ball locking pin.
Note: The inclination depends on the hole in which you x the
Easyy mount on the hole rail!

Mounting on box wall or traverse holder
1. When mounting the brackets on the wall (A) or truss (B), fol-
low the manufacturer‘s operating instructions.
2. Place the loudspeaker with the tilting pole socket on the wall-
and truss holder.
3. Adjust the inclination with the tilting pole socket.
Note: The tilting pole socket snaps into place by the weight of
the loudspeaker. If you want to adjust the tilt, you have to raise
the loudspeaker slightly.
Monitoring with Modular-15
Two monitoring angles, 50° and 20°, are available for monitor
operation with the Modular-15. The SpeakON®connectors at the
top and bottom of the loudspeaker are ideal for easy connection in
monitor mode.
