BW Broadcast DSPX-AM

AM Audio Processor

The DSPX-AM gives you a competitive edge—and builds listenership and revenue—by enabling you to achieve the tailored sound and loudness needed to make your station distinctive. The four-band and wideband AGCs, both with intelligent gating, along with a four-band, program-dependent limiter are enabled by a processing core using 16 DSPs with a combined power of over 1 giga-MIPS. Parametric bass enhancement, asymmetrical clipping, tilt EQ and AM low-pass filtering contribute further to keeping your station’s sound consistently loud and artifact free.

The dual processing paths make the DSPX-AM effectively two processors in one, feeding both your analog transmitter and a digital service, such as HD Radio, DAB, DRM or an Internet stream. The AM analog path has a multi-band distortion-controlled clipper, while the second path, tapped via analog and AES/EBU digital output connectors, incorporates a bit rate optimized, look-ahead limiter.
