The BW DSPX is a new generation of digital audio signal processor that can be used to process audio ready for
FM and digital broadcast.
The DSPX is the first UK designed and manufactured multi-band digital broadcast processor. Using the latest
multi-band DSP technology the DSPX offers a versatile and powerful tool in creating a loud punchy on-air pres-
ence.
The DSPX has been designed and built from scratch using a new approach to the design of a digital audio proc-
essor that incorporates the most up to date components. Cutting edge technologies allow the DSPX to produce
similar results to other processors in the market but in a simpler 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 DSPX is driven by a fast 8 bit micro-controller which controls an array of specialized analogue and digital
circuits: These include 24-bit A/D and D/A converters, analogue level control circuitry, 18 x 24 bit DSP's, an
Ethernet port, a trigger port, 2 x RS232 ports, 200 LEDS (metering), an LCD screen, 2 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 a wideband AGC processing block to nor-
malize input levels. The output of the AGC feeds the EQ and audio shaping sections before being split into four
bands by linear phase time aligned filters. The four bands are processed by a further four AGC'S before being
fed to 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 control system and LED metering display, 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 and by
remote (computer) control.
At a fraction of the size, weight and price of its rivals, the DSPX is a clear winner.
