GREETINGS!

Welcome to the Crown DP3 Audio Processor, the first digital audio processor

designed exclusively for the Crown Broadcast transmitter line.

The DP3 applies the same advanced design philosophy as the entire Omnia

family, to yield performance and flexibility never before available as an internal

transmitter option.

The DP3, like all Omnia products, delivers crystal-clear highs, thundering bass

and amazing loudness, with none of that “digital grunge aftertaste!”

The DP3 is a fully digital system that is available as an upgrade to current Crown

transmitters, and as a new product option for either our industry standard FM

transmitter line, or our FMX digitally controlled transmitters.

DP3’s flexibility is built-into the design. Instead of keeping the processing

algorithms on a set of EPROM’s or proprietary potted modules, the system’s DSP

(Digital Signal Processing) resources are entirely configured through software

contained in the DP3 card.

Even fundamental rearrangements of the system architecture can be easily

accomplished in the field by using the web-browser based remote control

application, via ETHERNET connection.

1 SECTION 1: DP-3 FIELD INSTALLATION

The Crown-Omnia DP3 Processor Card can be ordered as part of a new Crown

Broadcast transmitter, or it can be ordered as an upgrade for installation in a currently

owned Crown transmitter. In the first case we worry about installing the card. In the

second case you do.

Still, do not worry much. The DP-3 has been designed for straightforward, even easy,

installation into all Crown transmitters. “Easy installation” can be slippery terminology

when applied to complex technical items, but we think we can back it up here.

If you are upgrading a transmitter you already own, first of all let us congratulate you on

your decision to add the state-of-the-art audio processing of the Crown-Omnia DP-3 to

your broadcasts. Although we have been pleased over the years with the response we

have gotten from users of our basic processor design, we are very excited about the

addition of Omnia processing power to Crown transmitters.

The DP-3 adds many new possibilities to the sound of your radio. From Omnia presets

to your own personally tweaked signature audio, your broadcasts will never sound better.

PC control of the processing elements, along with programmable addresses for your

personal presets, give flexible new processing tools to every kind of user.

And even though we believe the DP-3 installation will be crystal clear and classic in its

simplicity, please take a few minutes to read through this chapter before proceeding with

the installation.

1.1 UNPACKING – VERIFYING PARTS

By now, you’ve gotten the DP-3 processor card out of its shipping pack. Check for

damage to report to your dealer. Be sure to inspect the DP-3 and shipping carton for any

shipping damage, which must be reported to your carrier for any claims.

The DP-3 shipping box includes the following items:

• DP-3 processor card

• DP-3 Operating Manual- which you are reading now.

• Warranty Registration Card (fill it out and return it)

• ETHERNET Cable
