BW DSPXtra Stereo Encoder & 6 band digital broadcast processor

The DSPXtra-HD 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 DSPXtra-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 DSPXtra-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, 22 x 24 bit DSP's, an ethernet port, a trigger port, a USB port, an RS232 port, over 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 conditioning circuitry before being presented to the Ariane RMS levelling block. The four band RMS leveller corrects for input level variations and also improves consistency. The block also can provide stereo enhancement or restriction with its 'matrixed' mode of operation. 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. Multiband look-ahead limiting plus precision final look-ahead limiter ensures your signal is kept to a strict maximum while maintaining consistent and clear sound.

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 control system and by remote (computer) control.

At a fraction of the size, weight and price of its rivals, the DSPXtra-HD is a clear winner.
