This versatile, DSP-based INOmini meets multiple broadcast needs. Quick menu-driven, application-specific setup for: NRSC, European or shortwave AM broadcast; Travelers 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 firms 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.Main Features:Ideal for: US/NRSC AM, Worldwide AM, Shortwave, US/Euro Monaural FM, TIS, and analog SCA.Easy menu / jog-wheel setup from the front panel.Performs AGC, 3-Band Compression, Peak Control, and Output Filtering specific to the selected application.User-adjustable compression, EQ, limiting, and program density.DSP lookahead limiting offers tight peak control without clipping.USB connector enables fast firmware updates in the field.Headphone jackSpecifications:Operating Modes: NRSC-compliant asymmetrical AM processing with 10kHz, 9kHz, 7kHz, and 5kHz (9-pole Cauer) cutoffs. TIS asymmetrical AM processing with 5kHz (9-pole Cauer) cutoff. FM processing (monaural) with 75s/50s pre-emphasis and 15kHz (7-pole Cauer) cutoff.
