I - INTRODUCTION

After years of success on the digital sound market with the DVP IDT decided to go further by proposing fully equipped, highly efficient processors taking up a minimum of space at the best price possible.

The 1U range from IDT has been designed to meet the needs of broadcasters by proposing powerful processors using Sharc DSPs ® from Analog Devices ®, a technology which gained the « Cool Stuff Award » award for IDT at the NAB, Las Vegas in 2000. This range proposes IU rack processors, thus using a minimum amount of space but with the power of a rack 3, 4 U or even more! Thanks to the up-gradable nature of the processors, both hard and software wise, they are without doubt the most complete and cost-effective solution on the broadcast market today.

The Digital Encoder Plus @ FM is full digital.

This manual will guide you through the set up of the DEP that you have just received.

 WEEE

WARNING

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.

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

 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 fuses with high power of cut

(ceramic body), 2AT 250V. In case of use on a 115 Vac. Network they should ideally be changed for fuses with high power of cut (ceramic body) 4AT 250V. The equipment needs an AC power supply of 115Vac or 230Vac 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.

II-1 - Connections

XLR audio in / Out

The I/Os of the DEP are linked by" XLR 3 Pin" connectors The wiring is the following:

Pin number 1 = Ground Pin number 2 = Hot Point

in number 3 = Cold Point P

 XLR Input

As with any professional audio unit the inputs are female so you need to use a male XLR to bring the audio into the DEP.

The DEP has a balanced electronic input. IMPORTANT: the input can receive balanced and imbalanced signals

 XLR Output

The audio output connectors are male so you need female XLRs to take the signal out of the DEP.

As for the input the DEP has a balanced electronic output. IMPORTANT: the output is protected against unbalancing (cold point to ground), so if needs be you can use this type of link.

 Specifications:

Local Switches/GPIO

The "Local Switches & Alarms" is aimed at switching presets by local switch and the feeding of the LEDs. On the DEP the connector is a SUB D 25 points.

The DEP allows the switching between presets. This is done by the grounding of one of the 8 pins of the connector. The switching can be done by a continuous contact or by a fugitive contact.

The DEP can also set off alarms (which can be parameterised by the Master Gate) on the 24 pins.

Access the « Local Switch » window in the Master Gate, go to the « SETUP » menu then select « LOCALSWITCH – GPI/O ».

When you have placed your cursor on one of the pins of the connector it will change colour to show which pin has been selected. .

When you click it you will access the various programmable functions of the connector. In the example below we will set pin 1 of the connector to switch a preset.

Window of the programmable commands.

The next window shows that pin n°1 of the connector is programmed to switch to the preset Mid + APC + HF Opt.

In the same way you can programme outgoing information or alarms. In the example below we have programmed the pin n° 14 of the connector an alarm

will be set off if the TX1 Level goes over 75 kHz.

The window below indicates the programmation of the pin n° 14 that we have just done as well as other programmations.

When a command is effective or an alarm has been set off this will be indicated by a red LED on the connector.

In the example above an alarm shows that the modulation of the TX2 is under that fixed by the TX2 programmation.

You have correctly installed the « Master Gate ». All you have to do now is link up to the processor.

II-4 – Connecting your processor to a PC

There are several ways to connect your PC to an IDT processor:

 Direct connection (Serial port RS232) Connect the serial cable (supplied) to the RS232 serial port of the PC (female

connector) and to the male RS232 port of your processor. (front or rear of the unit). Warning: DO NOT MISTAKE THIS PORT FOR THE MODEM PORT!

 By Modem Connect the Modem to the « modem » port of the processor. The necessary cable

is not supplied by IDT Sound Processing Corporation. IDT Sound Processing Corporation can only guarantee that the modem connection works correctly with modems that are HAYES compatible (US robotics for example).

 By TCP/IP If you have taken the Ethernet option with your processor you can connect via

TCP/IP. In this case fix an RJ45 class 5 cables to the RJ45 port on the rear of your processor. You can use a straight cable to link to a hub or a Switch or a to link directly to the network card of your PC or your router (ADSL for example).

Configuring the connections

The first thing to do is to launch the « Master Gate ». To do so click one of the icons created during the installation of the programme.

A screen will appear and the programme will look for the processors connected to the serial ports of your computer.

1. Direct connection

Normally, nothing has to be done to get the connection. When the application is first launched the programme will display the processors connected to the serial ports of the computer.

Choose the processor you want to link up to and double click its name. If you want to re-launch the detection of the processors click the « Serial Port »

icon on this screen.

If the connection doesn’t work make sure your serial ports are configured as follows;

To access these parameters go to the Peripherals Management window and double-click the COM port that you want to parameter.

Different configurations can work but IDT Sound Processing Corporation cannot guarantee that everything will be without problem.

2. Connection by Modem

To link up by modem, click the « Modem » icon on the Welcome screen of the Master Gate. The following screen will appear which is a kind of phone book of the processors you can connect to.

By clicking « New Entry », you can add a processor by entering the name of the programme, the town where the equipment is located and, above all, the phone number to call.

NB: IDT processors automatically reply when there is a call on the line connected to the modem. Make sure you are well protected by passwords.

3. Connection by TCP/IP

To link up by TCP/IP, as for the modem, you can click on the « IP Connection » icon of the Welcome screen of the Master Gate. « IP book » is displayed and the phone book of the processors you are connected to by TCP/IP.

By clicking « New Entry », you can add a processor by entering the name of the program, the town where the equipment is located and, above all, the IP address of the Ethernet card.

NB: As for a modem connection, the processors reply to each request, so think about protecting them with passwords!

To link up via TCP/IP, you need to know the IP address of your processor.

 DHCP

By default, the Ethernet cards supplied by IDT Sound Processing Corporation are configured to always request an IP address from DHCP server on the network you’re linked to. You should then ask the network administrator to give you the IP address attributed to your processor, and possibly to create a DHCP reservation for this address to make sure it’s never changed.

If your processor has a fixed address attributed to it and you wish to return to an automatic configuration of the TCP/IP parameters, you should follow the following steps and select « Dynamic addressing (DHCP) » in the Address Parameter screen of the processor.

 Attribution of a fixed IP address for your processor.

If your network does not have a DHCP server and you connect directly (by a crossed RJ45 cable) to the processor, or if this is imposed by your administrator you can attribute a fixed address to your processor.

To do so you must have installed the « IP Remote Manager » software. Connect your PC to the RS232 serial port located next to the RJ45 of your processor.

Launch « IP Remote Manager » via the shortcut in the Start menu: « programs, IDT Sound Processing, Tools, IP Remote Manager ».

Click the Serial Port button ». The software will scan all the serial ports of your PC to find the processor. The software will then display the results of the search:

Select your processor and click « next ».

NB: This window can be useful for your network administrator. He can read the MAC addresses of your processors, essential to create DHCP reservations.

On this window you’ll be able to give your processor a name (NETBIOS) and a fixed IP address. Ask your administrator to give you the other parameters (Subnet mask, gateway…) to ensure that communication can be established between your PC and the processor. This window will also allow you to return to a dynamic address assigned by a DHCP server.

By default, the TCP communication of our processors is 5001. This parameter can be changed. Ask your network administrator before making any modifications. This port can be re-directed via a firewall or a router for remote internet connections. Here again your administrator can help configure the equipment for this kind of connection.

 Firewall / Access control :

The IDT Sound Processing Corporation Ethernet cards have a simplified firewall which accepts or refuses connections coming from several IP addresses. These parameters should be set up with your network administrator.

To finish click « End ».The programme will then send the configuration to your processor after you have confirmed.

The processor can now communicate via TCP/IP by using the fixed address.

 SNTP synchronization

The Ethernet cards of IDT Sound Processing Corporation processors allows the synchronization SNTP (Simple Network Time Protocol). This function so allows synchronizing the hour of your processor as well as the integrated functions as the RDS.

On this screen, you specify the Time Zone, the IP address of the SNTP server, the interval of synchronization in minutes then the activation or not of the synchronization.

III-2 – The first settings

The first thing to do is to set the levels to correspond to you transmitter and to the standards applied in your country.

1. Setting the levels

WARNING ! ! !

Do not make these modifications while the DEP is linked to a transmitter. Make the settings with the TX1&2 unplugged or you could have over modulation.

 Setting the TX level

Click the « Level » icon in the central bar. Adjust the reference levels of TX1 and TX2

Then adjust the TX output level depending on the legal modulation levels of your country (generally 75 KHz).

IDT understood that you could need to parameter the second TX output to send the reference 19 KHz to an RDS encoder, for example. You can, thus choose a back-up multiplex output with this option.

If these results do not correspond to the levels measured by external equipment consult « Calibration of your processor ».

 Setting the analogue and digital levels

Still in the « Level » window, adjust the analogue and digital I/O levels to avoid any distortion of the sound before processing.

If your DEP is in a processing chain and that you are using the analogue or digital outputs of your processor don’t forget to set the output levels depending on the equipment your DEP is linked to. .

In this way you will avoid any peaks into or out of the DEP.

2. The Presets

The Digital Encoder Plus @ FM is delivered with a list of Factory Presets. These presets constitute the departure point for your sound settings and correspond to different radio programme categories. You can go, quite simply to the category that corresponds to your programme type but we strongly advise or to go through the different categories of Factory Presets to have a full idea of what is on offer.

Processing on the we call a which correspond.

WARNING: as the product evolves there are new Factory Presets which will

always refer to a version of layer even if we do all we can to ensure

compatibility between the various layers.

III-3 - Calibration process

To ensure that standards are met and to conform to other equipment in your audio chain our processors can be calibrated.

This process is quite simple and will take just a few minutes of your time Calibration is advisable when there are measurement discrepancies, when the

machine has not been used for some time or when there has been an electrical problem.

WARNING! This process will cut the audio signal and will replace it by a « sinus »! Don’t start this ON AIR.

Start by clicking « Calibration process» in the «Advanced » sub-menu of the « Setup » menu.

A series of windows will appear to help you through the process. Before starting link up TX1 and TX2 to measurement equipment. The

measurements can be in dBs, Volt peak to peak or in Volts.

To calibrate the processor click « Next », and the next screen will appear.

The first stage is to calibrate the main TX, (TX1). To set the DC, you have to first obtain 0V DC. 2 cursors allow you to obtain this measurement, « Coarse », and « Fine », to get the precise value. Then click « next ».

The next 2 stages are similar but concern the TX2.

Once you’ve adjusted the levels click « quit ». We advise you to save the calibration file on your hard drive or floppy so you can access it immediately.

Warning:

- A calibration file is dedicated to one processor. You will not be able to transfer file to another processor.

- Moreover the measurements may differ from one machine to another.

It is, imperative then to do a full calibration on each unit.

IMPORTANT :

In FM the stereo signal is transmitted by a carrier which takes care of the L+R information and a sub-carrier modulated by the difference L-R. This means of transmission, called Multiplex is, as a rule, robust. However when there are multi-path problems of the high frequency signal (generally due to an indented geographical situation) receivers (e.g. car radios) can find it difficult to get a clear signal. If you give to much breadth to the "Stereo Boost" Plug-

In you can increase significantly these multi-path problems.
