INTROdUCTION TO ThE dSPXTREmE
The BW Broadcast DSPXtreme is a new generation of digital audio signal processor that can be used to process
audio ready for FM and digital broadcasting such as HD Radio, DAB or internet radio.
Using the latest multi-band DSP technology the DSPXtreme offers a versatile and powerful tool in creating a loud
punchy on-air presence.
The DSPXtreme has been designed and built from scratch using a new approach to the design of a digital audio
processor that incorporates the most up to date components. Cutting edge technologies allow the DSPXtreme to
produce equvivalent results to other processors in the market but in a more cost effective way. The advances we
have made have allowed us to pass the savings on to our customers.
What's Under the Lid?
The DSPXtreme is driven by fast ARM7 and ARM9 micro-controllers which control an array of specialised ana-
logue and digital circuits. These include 24-bit A/D and D/A converters, analogue level control circuitry, 24 x 24
bit DSP's, an ethernet port, an RS232 port, a trigger port, two 3" TFT LCD screens (one of which is touch sensi-
tive), three sample rate converters, a headphone jack and memory devices to hold the software and firmware.
The Processing Architecture!
After input selection the 24-bit digital audio signal is passed through conditioning circuitry before being pre-
sented to the RMS levelling block. The four band windowed RMS leveller corrects for input level variations and
also improves consistency. The output of the AGC feeds the EQ and bass enhancement sections before being
split into six bands by linear phase time aligned filters. The six bands are processed by dynamic audio limiters
on each band. The unique dual processing paths allow simultaneous processing for FM and digital radio. Look-
ahead limiting and distortion cancelling clipping ensures your signal is kept to a strict maximum while maintaining
crystal clear sound. A supersonic sample rate DSP stereo encoder provides MPX generation with fantastic stereo
separation.
The easy to use front panel touch-screen control system and a separate metering screen, afford the user with
ease of use and setup.
Comprehensive control of every processing parameter is available to the user both from the front panel control
system and by remote (computer) control.
With superb specifications and big and loud on-air presence, the DSPXtreme is a clear winner.
