We live in a universe of sounds.

Sounds to be captured and reproduced, which can just accompany our life, but can also be exalting

and exciting. We were convinced we could reproduce this universe of sound in a new way – which is

why we created Verse. New manufacturing technologies for amplifiers and loudspeakers, combined

with a full digital control from the input socket up to the loudspeaker coil, made us decide to accept

this challenge. In fact, Verse is total sound purity, giving results whose quality is unrivalled in such

small dimensions.

Verse systems are built to astonish for their incredible quality and, thanks to their compactness and

light weight, can always fit in alongside you anywhere. Follow us in our new venture and make it

yours, re-discovering your universe of sounds.

OPEN SYSTEMS FOR OPEN MINDS

THANK YOU FOR CHOOSING A VERSE PRODUCT.

THIS GUIDE WILL GIVE YOU INFORMATIONS AND USEFUL TIPS FOR A CORRECT USE OF YOUR

D:SUB SYSTEM.

THE VERSE STAFF WISHES YOU GOOD WORK AND... HAVE FUN!

LOOKING AFTER THE PRODUCT

• Never apply excessive force to the structures or controls (knobs, switches).

• Do not stress the speaker in transit or during use.

• Do not place the device close to heat sources, in damp or dusty places or

close to strong magnetic fields.

• When possible, do not place the speaker close to units which generate strong

interference, such as radio and TV sets, monitors, etc.

• Never insert objects or liquids of any kind inside the device, for any reason.

• Clean using a soft brush or an air jet only; never use detergents, solvents or

alcohol.

• When disconnecting cables from sockets, always take hold of them by the

connector and not by the cable itself, and when winding take care to avoid

knots or twisting.

• Do not expose the speaker to direct sunlight.

CONNECTING TO THE MAINS

• To avoid the risk of electric shock, do not make connections with wet hands.

• Make sure that the mains voltage is the same as that indicated on the control

panel.

• Connect the speaker to a mains socket with earth contact.

CONNECTING TO A MIXER

• Always use good quality screened cables.

• Before making the connections, check that all the speakers you are about to

connect are switched off. You will avoid noisy, if not hazardous, signal peaks.

IN CASE OF MALFUNCTION

• In case of malfunction, contact only an authorised service centre.

Verse speakers are developed from the idea that speech and music satisfy us

when they are intelligible, undistorted and pleasant to listen to.There’s no

such thing as a system suited to one musical genre or another – these are just

illusions caused by our personal taste. A real sound system can follow you

anywhere: whether you’re in a lounge bar accompanying an aperitif, in a

traditional theatre, or just outdoors with a few instruments or a large

orchestra.

In order to do this we applyed the latest design and manufacturing

technologies, and DSP processing, and that's what gives Verse systems a huge

reserve of dynamics, which can be heard when the need arises.

The experience of listening to Verse will enable you to discover many new

horizons - a real uniVerse:

• natural, dynamic low frequencies that are not pumped up, but give an

unforgettable physical sensation

• a great natural reaction to equalization, to satisfy users’ personal taste,

thanks to the great reserve of dynamics and the capacity of the new

transducers

TECHNOLOGY

DIGITAL AMPLIFIERS

The new digital technology totally changed the way a professional audio

amplifier is developed. No other way make possible to give great power and

long term reliability.

Remarkable heat reduction and outstanding weight decrease make digital

amplifier, that equip VERSE D:SUB, efficient, powerful and less heating. The

output stages of the amplifiers typically run at 95% efficiency, dissipating only

5% of the input energy as heat.

Moreover the efficiency doesn't depend on the output level, and Since

standard music has an average power density of 40% of the maximum level,

conventional amplifiers can easily generate 10 times more heat than VERSE

ones for the same volume of sound.

To grant reliability and durability, VERSE amplifiers are provided with short-

circuit protection, thermal protection with fan-speed control (that avoid

temperature rising over 60° C) and amplifier disactivation system thus

preventing amplifier breakdown if temperature rise to intolerable values.

And also: protection circuit to cancel direct current component, protection

from ultrasonic components in input and output. The I.T.P (Intelligent

Thermal Protect) is warranty of perfect-working and long-lasting speakers.

TOP QUALITY COMPONENTS

Together with high performance amplifiers, VERSE decided to put speakers

conceived specifically to do their best with a so remarkable reserve of power.

The woofer are made with neodymium magnets that allows the highest force

factor and excursion capability, and with ventilated voice coil gap for reduced

power compression. With such components it's easier to obtain huge

excursions, "present" and dynamic bass, high acoustic pressure and mild

weights.

DIGITAL PROCESSING

The processing system included in every D:SUB loudspeaker is based on a

performing DSP processor with PC-based remote control using dedicated

software. Sophisticated and innovative processing algorithms have been

implemented to ensure total protection of all system components without

sacrificing the dynamic of the sound source. Digital Limiters switch on when

transducers safety conditions or maximum amplifier power are going to be

exceeded, preventing the loudspeakers from being supplied with higher

volume input signals.

The processing unit includes as well a multi-band compressor, a delay line,

six full parametric equalizers and a dynamic loudness controller. The digital

delay line makes it possible to compensate for vertical alignment differences

between subwoofer and satellites or to create distributed lines of speakers

whose output reaches the listening point simoultaneously, eliminating echo

effects.

The multicomp processor and the Dynamic Loudness section can be extremely

useful for the system's dynamic EQ. While the Dynamic Loudness try to adapt

the output level according to the well known "Fletcher&Munson" curves, in

order to keep the original sound richness also at low level signals, the

Multicomp offers a more deep capability to modify and manipulate the

dynamic range of the audio signal.

A six band full parametric EQ may be used to tune the overall audio response

to the need: adapting the frequency response to the ambience, to the musical

genre or speaker voice, to the peculiar use of the moment, to personal tastes,

etc.

D:SP EDITOR

To easily customize every parameter of your loudspeakers a PC editor

program is available. This allows to connect to the speakers, editing

equalizers and parameters, but also displaying levels, and checking the status

and "health" of every single loudspeaker connected to this network, showing

real time temperature, signal overloads, limiter activities and other status

information of the D:SUB.

1 & 5. LEFT/RIGHT LINK: sends to the output the same signal coming from

LEFT/RIGHT INPUT connector. This allow the cascade connection of different

devices to the same sound source.

2 & 6. LEFT/RIGHT INPUT: XLR input socket for connection of the signal to be

amplified.

3. RS485 OUT : Etherconn connector to connect to the digital network. Use to

connect to the RS485 IN input of the next speaker along the daisy chain.

4. RS485 IN : Etherconn connector to connect to the digital network. Plug here

the cable coming from the RS485 OUT connector of the previous speaker in

the daisy-chain, or the USB-485 interface (D:SP INTERFACE) output if the

speaker is the first in the chain.

7. LEDs:

- ON LED: indicates that the speaker is On.

- Prot. LED: indicates that the internal amplifier switched to protection mode

due to a fault of the amplifier itself or of the connected speakers (please call

the technical support).

- Temp. LED: indicates that the internal amplifier switched to protection

mode due to excessive heating. In this condition, the amplifier supply half

the normal power. Please reduce the input signal to allow the restore of

normal load conditions.

- Comp. LED: indicates activity of the compressor. If the signal passes over a

safety threshold, the compressor guarantees a good quality playback without

acoustic distortion, damping the appropriate signal frequencies. The system

operates in total safety. If the LED is constantly On, there is an excess of

signal. In this case, please reduce the incoming signal level.

- Sign. LED: indicates that the signal is present.

8. Gain: to adjust the signal gain in range from -35dB to 0dB.

9. Mains In: connect the mains cable supplied from the factory with the

loudspeaker to this socket.

10 & 12. AC Power Out: easily connect up to other two VERSE speakers to the

mains. Pay attention not to exceed the limit reported on the chassis near to

the connectors.

11. POWER: Switches the power on/off.

SCREW

All the D:SUB series speakers are equipped with a powerful DSP (Digital Signal

Processor) which manages the entire signal processing flow. Some of the advanced

functions are ready to use via the simple interface made out of LED-lighting

switches, accessible when removing the "DSP" panel as shown in the figure. Every

function, described below, can be activated pressing the proper switch. When the

LED is on the DSP function is activated.

The list of LED-switches follows with a description:

- 180° ph.: invert the phase of the input signal.

- User: activates the "user settings", prepared with the proper software editor,

D:SP EDITOR sold separately. Whenever the previous setting is not adequate to

the peculiar use case, it can be deactivated, switching back to the factory

settings.

Note: The "User" preset is not set by factory, which means the speaker

configuration remains the same either the User LED is turned On or Off,

until a user setting is not configured.

The Powercon connectors make the system very practical and, thanks to the LINK

OUTPUT on each enclosure, avoid the problem of having to run a power feed to each

element.

All VERSE Systems are provided with special customized cables made of a pair of

powercons and balanced XLR connectors. Therefore it is possible to provide for

signal and power a VERSE D:SUB from another VERSE D:SUB or a VERSE D:SIDER.

Subwoofers feature a double output link to simplify the left and right audio channels.

Please note: the purchase of a spare VERSE speaker (i.e: not buying it in a -k system)

doesn't include the customized cables.

Configuration 2. 2-channels 2-SUB connection

In addition to the DSP functionalities, directly accessible on the speaker,

described in the previous paragraph, it's possible to control in a broader way

the speaker of the D:SUB series using an RS485 remote control interface and a

personal computer. An optional USB-485 interface (D:SP INTERFACE) and a

personal computer software (D:SP EDITOR) are available to the purpose. In this

way it's possible to control a large amount of parameters within the signal

processing and to monitor in real time important aspects of the speakers

functioning.

With a single USB-485 it is possible to connect in daisy chain up to 127

different speakers.

For a complete description please refer to the D:SP EDITOR + D:SP INTERFACE

user manual. It is anyway possible to have a preview of the available

functionalities, installing on a personal computer the DEMO version of that

software, that can be found in the attached CD or be downloaded from the

official site www.verseaudio.com

Note: to connect the D:SUB speakers to the network use only high quality

Ethernet cables of the CAT5 type.

An example of a daisy chain network for the VERSE D:SUB systems is shown in

figure below.

Warning: even if the digital D:SP Verse network is made of common

Ethernet cables, IT IS NOT an Ethernet network, therefore IT IS NOT

possible to connect the D:SUB speakers to Ethernet devices. It is, instead,

necessary to make use of the proper VERSE D:SP INTERFACE (USB-485),

available as optional.

This manual assumes that the owners and/or users of a VERSE System are

knowledgeable and experienced in the areas of Pole use with loudspeaker

systems. The suspension of large, heavy objects on a Pole in public places is

subject to numerous laws and regulations at the national/federal,

state/provincial, and local levels, that are not addressed in this manual.

However, the user must assume responsibility for making sure that use of any

VERSE system, its components and all the poles and associated hardware in

any particular circumstance or venue conforms to all applicable laws and

regulations in force at the time.

WHEN USING POLES, BE SURE TO OBSERVE THE FOLLOWING PRECAUTIONS.

CHECK THE POLE SPECIFICATION TO BE CERTAIN THE DEVICE IS DESIGNED TO

SUPPORT THE WEIGHT OF THE SPEAKER. OBSERVE ALL SAFETY PRECAUTIONS

SPECIFIED BY THE MANUFACTURER. MAKE SURE THAT THE SURFACE ON WHICH

THE SYSTEM IS TO BE STACKED IS FLAT, STABLE AND SOLID. ROUTE CABLES SO

THAT PERFORMERS, PRODUCTION CREW, AND AUDIENCE WILL NOT TRIP AND

TOPPLE THE SPEAKERS. INSPECT THE POLE AND ASSOCIATED HARDWARE

BEFORE EACH USE AND DO NOT USE EQUIPMENT WITH WORN, DAMAGED, OR

MISSING PARTS. DO NOT ATTEMPT TO PLACE MORE THAN ONE VERSE D:SIDER

LOUDSPEAKERS ON A POLE.

ALWAYS BE CAUTIOUS WHEN DEPLOYING THE SYSTEM OUTDOORS.

UNEXPECTED WINDS MAY TOPPLE A SYSTEM.

AVOID ATTACHING BANNERS OR SIMILAR ITEMS TO ANY PART OF A SPEAKER

SYSTEM. SUCH ATTACHMENTS COULD ACT AS A SAIL AND TOPPLE THE SYSTEM.

UNLESS YOU ARE CONFIDENT THAT YOU CAN HANDLE THE WEIGHT OF THE

SPEAKER, ASK ANOTHER PERSON TO HELP YOU GET IT ONTO THE POLE.

Whenever the VERSE speakers are placed on a pole, using a properly arranged

subwoofer speaker as support, the maximum stable height, granting stability

and no toppling of the system, depends on the subwoofer speaker

dimensions. Provided that the users are charged by responsibility of a correct

installation and by thorough stability check, a reference guideline is given by

the following table:

The acoustic characteristics of the room/environment in which a sound system is used have

sometimes very significant effects on the overall sound produced.

Thanks to its special technical features (such as the optimal width of its dispersion range),

with the VERSE D:SUB some of the most common problems can be reduced or prevented.

However, some factors should be borne in mind as they may help to optimise its

performance.

• Do not place speakers in the corners of a room or in recesses (e.g. niches), since this

causes an increase in the low frequencies, producing sounds which are redundant or

blurred.

• Do not place speakers against a wall, as this also causes an increase in the low frequencies,

although less pronounced than that produced in a corner or niche.

N.B.: on the other hand, this phenomenon may sometimes be used to advantage to

reinforce the low range, but it must be employed carefully and in a controlled way.

• Do not place speakers straight on a stage, a floating floor or any other support with

cavities, as this tends to trigger resonances that alter and interfere with the overall sound.

N.B.: solid supports should always be used when possible, or a speaker stand.

• Remember that high frequencies have a high level of directivity and a much higher

absorption coefficient than low frequencies. Therefore, to guarantee that the signal

reaches the listener in an intelligible form, position speakers so that they are in a direct

line with the audience (clearly visible) about ½ metre / 1 metre above the audience’s heads.

• In buildings with a lot of reverberation (places of worship, gymnasiums, etc.) first of all

keep the sound reflections down using materials which absorb sound (carpets, curtains,

special panels, etc.). If this is not possible or is not sufficient, do not simply turn up the

volume, because this will also increase the volume of the reflected sound, and may make

the situation even worse. The best solution is to use more speakers, placed around the

room and closer to the audience (e.g. front+back; front+sides; front+sides+back).

N.B.: in these circumstances it may prove necessary to use the integrated delay line

provided with the D:SUB internal DSP processor realign the timing of the sound of the

various speakers (i.e. to overcome the delays caused by the sound propagation time),

ensuring that the sound heard by the audience will be free from “echo”.

Example: since the speed of sound is about 344 metres a second, sound takes about 1/10

of a second to travel 30 metres. Therefore, a listener close to a “back” speaker 30 metres

from the “front” speaker would hear the sound from the “back” speaker about 1/10 of a

second before the sound from the “front” speaker: in other words, he would hear two

identical sounds 1/10 of a second apart. To ensure that the two sounds strike the ear of

this specific listener at exactly the same time, the sound of the “back” speaker will have to

be delayed by 1/10 of a second using the D:SUB Delay line.
