I - INTRODUCTION

The Basics of Signal Processing

At the outset of radio broadcasting the only technical constraint imposed on the audio signal was to ensure that the electrical value of peaks was limited in order to guarantee maximum modulation while respecting legal specifications.

Rapidly the necessity to reduce the dynamics of the signal became necessary if only to increase its reproduction and the audio quality in the diverse areas where radio was listened to.

Today, the increased competition between radio stations has brought the need to resort to more and more sophisticated equipment to process the modulation by rendering the spectre much denser.

The DBP 7+4 that you have just bought is part of the latest generation of audio sound processors. The DBP 7+4 is doted with unique algorithms which process the audio signal, not in the temporal field as other units but in the frequency field by using FFT. The new DBP 7+4 is in a class of its own in all respects;

 The heart of the FFT processor has been totally revamped and, as a result,

much improved.

 New functions have been brought in to enhance precision and to make the

settings more flexible.

 The architecture of the programme has become far more stable.  Modifications have been brought hardware wise thus improving the

exchange of digital audio data.

This manual will help you to rapidly take control of your DBP 7+4 and to master its power to obtain a modulation that is dense yet natural.

II - INSTALLATION

Dedicate one hour to the installation.

WARNING : IDT declines all liability should the rules of installation below not be

respected.

 Physical Installation

As you will have noticed all IDT products are of a 19 inch format so that it fits into dedicated racks. The following indications must be respected.

We advise using a rack-mount; however, the front panel was designed to be sturdy enough to be self-supporting with the four screws firmly implanted.

The ventilation of your processor : the ventilation has been studied to make sure that all heat generated is evacuated. Air is sucked in by two ventilators, placed on the right and is expired at the rear and to the left of the unit. These ducts should absolutely not be obstructed. Make sure that your processor is placed where hot air can be evacuated. The ideal location is in an open rack, dry area where, ideally, it is not exposed to high temperatures (behind a window with bright sunshine, a radiator, amplifier etc).

IDT processors have been tested to work in environments where the temperatures go from 0°C to 45°C. IDT Sound Processing Corporation cannot guarantee that its processors work perfectly outside these temperatures.

 Electrical Installation :

Good grounding: IDT processors are CEM certified guaranteeing that the

equipment can function in an electro-static environment. The key is to make sure that the equipment is properly grounded as results please fix all 4 screws of the front panel to the rack to allow. All IDT processors also have a ground connector at the rear of the unit which allows a connection to the rack.

NB : don’t forget to connect the ground link of the rear panel to the rack!

The right fuses : The fuses in the power supply are, standard, 2AT 250V. In

case of use on a 115 Vac. network they should ideally be changed for 4AT 250V. The equipment needs an AC power supply of 115 Vac or 230 Vac 50/60Hz and must be properly earthed. There is an earth screw on the equipment for that purpose. Should the equipment not be in use for a certain period it should be unplugged. .

The right Cable : IDT are supplied with standard IEC AC cables. The cables are French standard. This cable should be changed to respect the electrical standards of your country. IDT Sound Processing Corporation cannot guarantee any breakdowns should a non-standard cable be used.
