This versatile, DSP-based INOmini meets multiple broadcast needs. Quick menu-driven, application-specific setup for: NRSC, European or shortwave AM broadcast; Traveler’s Information Service; monaural US or European FM; analog SCA services. 3-band processing has selectable crossovers, EQ and tight limiting with pre-emphasis protection. The DSP-based 223 is an addition to the firm’s INOmini line. Features include gated and windowed ‘gain-riding’ AGC, 3-band compression with adjustable EQ, and a fast ‘lookahead’ final limiter coupled with overshoot-controlled multi-cutoff output filtering to suit a variety of uses.
The 223 has a very intuitive menu-driven user interface. All modes employ protection-limited pre-emphasis and bandwidth constraint specific to the service selected. The triband compressor section has selectable turnover frequencies, and a unique ‘smooth vs. loud’ adjustment gives clear-cut control over program density.
The compact 1/3-rack-size unit integrates with other Inovonics INOmini products, including RDS encoders and decoders, AM/FM/HD-Radio confidence monitors with IP control and streaming audio, and other economic problem-solvers for broadcasters. Although the 223 replaces a legacy AM-only processor, the versatile new unit finds ready application with other broadcast services as well.
