The high-quality integrated audio processor is more than an audio
limiter found on most transmitters. It has all of the features of
expensive broadcast processors, including:
Slow gain-riding section (AGC). This will optimise all sources for
equal volume over time. So if one studio operator drives the
mixing desk louder or quieter than others, the level will
compensate accordingly.
Multiband Compressor Limiters. Bass, mid and high frequencies
of programme material are split and processed differently. This
avoids the ‘pumping’ associated with single-band limiters, where
higher frequency sounds are affected by bass powerful content.
Final HF limiting and distortion-cancelled composite clipping
ensures that deviation can be optimised, without ‘overshoot’ to
above 75kHz.
DSP FIR 15kHz audio filtering maintains audio high frequencies
up to 15kHz, but preserves the Pilot signal at 19kHz, and the
RDS sub-carrier at 57kHz.
The menu includes the ability to select from 3 pre-sets, so that
broadcasters can choose the audio style that best suits their station.
