IntroductIon to the dSPXmInI-hd
The BW Broadcast DSPXmini-HD is a new generation of digital audio signal processor that can be used to proc-
ess audio ready for digital broadcasting such as HD Radio, DAB or Internet streaming. Using the latest multi-
band DSP technology the DSPXmini-HD offers a versatile and powerful tool in creating a loud punchy on-air
presence.
The DSPXmini-HD has been designed and built from scratch using a new approach to the design of a dig-
ital audio processor that incorporates the most up to date components. Cutting edge technologies allow the
DSPXmini-HD 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 DSPXmini-HD is driven by a fast 8 bit micro-controller which controls an array of specialised analogue and
digital circuits: These include 24-bit A/D and D/A converters, analogue level control circuitry, 6 x 24 bit DSP's,
an ethernet port, a trigger port, an RS232 port, an LCD screen 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 split to
four bands by linear phase time aligned filters. Each band is processed by multiband RMS leveller which corrects
for input level variations and also improves consistency. Each band is further processed by dynamic audio lim-
iter. The following precision look-ahead limting ensures your signal is kept to a strict maximum while maintaining
clean and natural sound.
The easy to use front panel control system with LCD 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.
At a fraction of the size, weight and price of its rivals, the DSPXmini-HD is a clear winner.
