1. IMPORTANT REMARK

Congratulations! You are the owner of a carefully designed and manufactured equipment. We

thank you for having purchased our DPC processed system.

It is VERY IMPORTANT that you read this manual before connecting the unit in order to obtain its

maximum performance.

We recommend our authorised Technical Services whenever any maintenance task should be

needed so that optimum operation shall be achieved.

1.1. Safety Precautions

The DPC is capable of delivering maximum sound pressure levels greater than 150dB SPL at 1

meter. These sound pressure levels can cause permanent damage to human hearing. Protect your

ears when working at high power next to the system.

The DPC is a closed sound system designed to operate exclusively with ECLER amplifiers and the

DP300 digital processor, not only offering a well-balanced sound, but also ensuring perfect operating

safety. Using other components than the specified ones, be it from ECLER or from other manufactures, will

both worsen the system performance and mean a risk of serious damage to your loudspeakers.

The mids-highs enclosures DPC215 should be connected with 4-core cables. DO NOT use

conventional 2-core cabling (see paragraph 3.4)

2. INTRODUCTION

The DPC7000 (DIGITAL PROCESSED CABINET) has been specially designed for fixed or

mobile installations where high sound pressure levels and exceptional audio quality is required. We are

talking about a processed system capable of delivering a maximum SPL level of 150dB/1m.

The system consists of two DPC215D midrange / high frequency enclosures, four DPC118

subwoofer enclosures, the DP300 processor and following amplifiers, according to the version:

DPC7000D DT6800 DT4800 DPA600

DPC7000P* DPA4000T DPA2500T DPA600

The digital loudspeaker processor ECLER DP300, apart from actively dividing the audio

spectrum into three bands, equalizes each of these bands, allows accurate phase correction and delay

on each way. Additional system protection is provided with the use of a built-in compressor/limiter. The

DP300 can be remotely configured via the included software and can be set-up to either suit the D or P

version of the DPC7000. For further information about the DP300 processor, please refer to its specific

user manual.

This process is combined with the anticlip circuits from the high frequencies amplifier DPA600

and the A2SP (Analog Autogain Signal Processor). The A2SP is an Autogain protection and intelligent

anticlip system controlled by an VCA (Voltage Controlled Amplifier) and is included with the DPA2500T

and DPA4000T amplifiers. This anticlip system has different operation levels depending on the transient

signal type.

STEP BY STEP THROUGH THE DPC7000

REDUCED DIMENSIONS AND WEIGHT HIGH PERFORMANCE

In the last years, the evolution of professional sound systems has been certainly influenced by

two facts: The reduction of acoustic cabinet size and the ever increasing output power of amplifiers.

Systems are now lighter, smaller and more portable, while the sound quality approaches more and more

that of a Hi-Fi system. Electronics is the key of this advances. The components generally called

"processors" are able to push a sound system to its limits. These intelligent electronic systems,

sometimes contained in the amplifier itself, but in most cases mounted into dedicated processor units,

constantly monitor the systems operating conditions. The result is a total reliability as far as the systems

behaviour is concerned, which is the main obsession when installing professional sound systems.

THREE-WAY SYSTEMS: THE PERFECT SOLUTION

This is the optimal system to achieve faithful voice and music reproduction. It's a fact that the

human ear is more sensible in the central portion of the audible spectrum, which enables us to easily

recognize any kind of irregularity in this frequency range. This justifies the need for a dedicated driver for

the reproduction of the human voice, which ranges from 200 to 1500Hz).

The overall structure of the DPC systems is based on two cabinets: The first one only reproduces

the lowest frequencies below 150Hz, while the second one reproduces both the midrange (from 150Hz

to 1500Hz) and the high frequencies (from 1500Hz to 22kHz).

FOLDED HORN TECHNOLOGY

The design of practical and easily transportable loudspeaker enclosures for the reproduction of

low frequencies using folded horn configuration has always been a challenge for acoustic designers. An

accurate reproduction of very low frequency signals involves very long horn lengths (e.g. 6.9 meters for

50Hz. Folding the horn is the only solution to overcome this physical inconvenience.

The DPC7000 employs a highly effective bass reproduction system based on two complementary

enclosures, which should be placed so that their lateral triangular marks are face to face (see paragraph

3.1.). The DPC118 enclosures employ an incredibly efficient tractix type folded horn design. This

approach permits the use of longer horns which amplify the bass frequencies while keeping the

enclosure size to a minimum and thus making them easily transportable. On the other hand, this

acoustically optimized system guarantees high efficiency and low distortion. The final result is an

enclosure that offers 6dB more per Watt on average than a standard bass-reflex enclosure with two 18’’

drivers. As a consequence, less enclosures and less amplification are necessary for a given installation.

The 18’’ speakers (45.7 cm) mounted on the DPC118 employ a powerful neodymium magnet and

a 100mm voice coil. The speaker is able to withstand maximum excursions up to 20mm and input power

of 1200W AES.

6

DIRECT RADIATION WITH TWIN SYSTEMS

Very high radiation levels can be achieved with this method, which consists of mounting two

identical drivers into the same enclosure. The drivers need to be perfectly matched in their

characteristics, as otherwise unwanted mutual loading may develop. This technique represents a 3dB

radiation increment in comparison to single driver configurations.

Both 15'' (38,1cm) speakers feature 100mm voice coils and withstand maximum excursion up to

4mm. For the high-frequency way, a neodymium motor has been used along with a 2'' ferrofluid voice

coil and a titanium diaphragm coupled to a plastic-moulded antiresonant constant-directivity "phase plug"

diffusor. These pieces are placed between the diaphragm and the horn throat, avoiding cancellation of

certain critical frequencies. The high frequency driver is mounted in d’Appolito configuration, i.e. placed

between the two 15’’ speakers.

ACOUSTIC ENCLOSURES

Wood and construction

If the employed components represent 51% of the success of an acoustic system, the remaining

49% belongs to the acoustic enclosure and its construction. The plywood panels used on the DPC is

very stiff and light. The boxes feature braces which minimize coloration caused by surface vibration.

Constructed with 15mm plywood, the midrange and high-frequency cabinets include a wooden ring

inside the box which snugly fits around the tweeter motor thus reinforcing its subjection and protecting

the diffusor from possible impacts or vibrations. Its trapezoidal shape has a 6° angle on each side. The

low frequency cabinet is built from 18mm birch plywood. Both enclosures feature inset handles to make

transporting and handling easier.

Absorbers

Inside the box, stationary waves can originate and affect the sound purity. One way to minimize

this effect is to use absorbers. DPC cabinets use antiallergic, oncologically inoffensive synthetic fibre

glued onto the inner box walls.

Painting

A new resin-based chemical component provides a high durability treating, being scratch and

bump resistant.

Hardware

The loudspeakers are protected with a foam-covered metal grille (foam on inside), preserving

them from dust and splashings. This assembly is solidly attached to the enclosure with screws. The

midrange and high frequency cabinets feature two adjustable fittings on the top and bottom side which

allow the use of a flying suspension system. (see 3.2)

Preinstalled fittings for mounting most wheel types found on the market. (See paragraph 3.3)

Connection panel with SPEAKON® connectors.

VERSIONS AND ACCESSORIES

Apart from the basic version consisting of acoustic cabinets, amplifiers and the processor unit, a

complementary version is available for upgrading purposes: The DPC7000 PC/DC. The only difference

lies in the fact that this version does not include the DP300 processor, as bigger systems need just one

of these units.

It is also possible to fit all system electronics into a flight case (ref EPC FL). 10m connection

cables are included apart from the internal wiring and connection panel.

bypassed) or master device (DP300 working).

EPP AINT 15m multicore cable for interconnecting two EPP LINT or successive units.

3. INSTALLATION

3.1. Placement and mounting

The acoustic characteristics of the room, hall... and the number of

assistants must be taken into account. General rules valid for any case:

Place the acoustic cabinets on solid and firm surfaces. The bass

reinforcement cabinets DPC118 should be paired so that their marks are

face to face (see diagram), ensuring optimal low frequency reproduction.

The Bass enclosures are more efficient when placed directly on the floor in

landscape orientation rather than vertical, elevated or hanged. We

recommend to stack the bass cabinets vertically for a better sound quality.

Be sure that there is not any obstacle between the mid-treble

cabinets and the audience; the high frequencies are extremely directive and

any obstacle represents an attenuation. For a big audience, the higher you

place the mid-treble cabinets, the better sound propagation you will get.

Although all the DPC cabinets protect the loudspeakers with a grille and a

foam do not expose the system to the sun for long periods and avoid the

rain.

3.2. Rigging speaker enclosures

Following general guidelines must be considered:

- Always place acoustic enclosures on solid and firm ground.

- No obstacles should lie between the loudspeakers and the

audience.

- High frequencies, as opposed to low frequencies, tend to be

much more directional and any obstacle in the acoustic wave path

represents attenuation in the frequency response of the system.

The midrange and high frequency cabinets DPC215 feature an

effective flying system consisting in four adjustable tracks, the same

types as used in air cargo equipment (ISO 7166 standard). These

tracks allow flying one or two rows of enclosures, directly hanging the

second row directly from the first one. Four tracks are fitted at the

cabinet walls, two at the top and two at the bottom. These fittings are

additionally fixed to the lateral walls via internal metal braces. The

bottom tracks not only allow hanging additional enclosures, but also

permit a tilt of the system.

8

The enclosure will acquire

different tilt as a function of the

chosen link. Following table shows

the tilt angles for one single

enclosure. It the tilt angle is not steep

enough, tilt it further by using the

bottom rails.

In case two rows are utilized,

we recommend tilting the assembly

from the bottom track.

Each position of the

aeronautic specified cargo restraint

track has a maximum load capacity of

180kg, considering the enclosure is

correctly flown, as shown in the

diagrams.

The tracking system works in

combination with Ecler ADP cargo

restraint double stud and ring. (Adam

Hall Ref. 5740).

The total load capacity of the

structure (track + ring) is limited by

this track and is 180kg per anchor point. (360kg total).

Always make sure that the anchor points are firmly attached to the rail and locked.

3.3. Mounting the wheels

In case the system is to be used

for mobile applications, we recommend

the QRA and WH200 accessories.

The QRA consists of four fittings,

which once attached to the cabinet in the

appropriate locations, allow the quick

assembly and disassembly of the castor

wheels, thus avoiding annoying vibrations

during sound reproduction.

The WH200 is a four-piece castor

wheel set, suitable for the QRA.

3.4. Connecting the system

Connection to the acoustic cabinet. This connection must be done with, at least, 3mm cable (we

recommend 6mm). The amplifier output and the acoustic cabinet input connectors are 4 pin SPEAKON

(see diagram A). The mid-treble cabinet will be connected as follows:

Treble + > Pin 2+

Treble - > Pin 2-

Mid + > Pin 1+

Mid - > Pin 1-

The bass reinforcement cabinet only uses pin 1+ and pin 1-.

3.5. Interconnecting two or more systems

With one single DP300 base unit you may interconnect up to 10 DPC7000 PC/DC systems

(complementary unit without processor). You just have to use the Stack outputs found on any amplifier.

These Stack outputs should be connected to identical amplifiers. IMPORTANT

: The successively

interconnected amplifiers must be adjusted with identical settings as the amplifiers which are directly

connected to the DP300.

Another option is to use complete DPC7000 systems configured as master or slaves, depending

on the functional requirements. For that purpose we have designed the EPP LINT and EPC AINT

multicore, which let you interconnect several DPC units, configuring them as master or slave. The

master system will inhibit all the system associated processors. (See diagram B/C)

A set of small switches placed at the left side of the EPP LINT circuit board help you to use one

system for different configurations when stacking systems. It is for instance more convenient to use each

power amplifier rack in mono mode when working with even numbered systems (2, 4, 8…) (see diagram

B).

On the other hand, when working with odd numbered systems (3, 5, 7, 9…), one system would

operate in stereo (MASTER system) and the rest in mono mode (see diagram C).

Following this advice will in both cases minimise cable runs, as each power amplifier rack can be

placed next to the speakers, which is the most recommendable situation.
