1. IMPORTANT REMARK
Congratulations! You are the owner of a carefully designed and manufactured equipment.
We thank you for having purchased our EPC200 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.
2. INTRODUCTION
6000 W PROCESSED SOUND SYSTEM
The EPC (ECLER PROCESSED CABINET) 6000 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 offering 5032W RMS/4Ω/1kHz/1%/THD, capable of
delivering a maximum SPL level of 147dB/1m.
The system consists of two EPC215D midrange / high frequency enclosures, two
EPC218D subwoofer enclosures, three SPM* Technology power amplifiers (PAM600,
PAM2000 and PAM2600) and the EPC200 processor. This last component, apart from actively
dividing the audio spectrum into three bands, equalizes each of these bands and allows
accurate phase correction on each way. To complete the process, each SPM amplifier includes
an additional ANTICLIP circuit with an optimally chosen THD threshold setting for each
loudspeaker.
STEP BY STEP THROUGH THE EPC 6000
REDUCED DIMENSIONS AND WEIGHT HIGH PERFORMANCE
In the last ten 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.

With this technology (Switching Power Mosfet), developed and patented by ECLER, S.A., ECLER
introduced in the early 90s a new concept to the world of professional audio: The use of switching field
effect transistors. The use of these parts for audio applications represents a firm and spectacular
enhancement comparing to conventional amplifiers. These advantages can be outlined as follows:
Lower internal resistance than bipolar transistors, which leads to less heating of the amplifier and
more powerful and controllable bass.
Conventional Mosfets have a 4 to 7 times bigger internal resistance than switching Mosfets.
The extremely high speed of these devices gives a transparency to the upper frequencies till now
only achieved by tube amplifiers. This fact also reduces TIM (transitory intermodulation) to very low levels.
