The Poseidon is a 5 band digital processor with 30 pre-programmed equalization curves, offering 10 additional equalization curves that can be personalized. The personalized equalization curves can be easily saved and recalled. Each editable parameter is user friendly, allowing even inexperienced technicians to operate sound changes. The settable parameters are: Super Bass Type, Super Bass Level, Bass Compressor, Mid1 Compressor, Mid2 Compressor, Mid3 Compressor, High Compressor, Broadband Density, and Brilliance. In addition to the 10 personalized presets, Poseidon features a bass enhancer that can be settable through Super Bass Type and Super Bass Level, and a noise gate with variable threshold. Poseidon is totally remote controllable through serial ports directly by PC or via satellite.

Poseidon features two independent serial ports uncoupled by opto-isolators. This assures maximum immunity from other equipment noise. Digital input is optional. Standard are: stereo enhancer and digital stereo generator MPX . Poseidon digital input and RDS modulator are optional .The Digital Input can be connected in two ways: through a balanced XLR connector or a standard fiber optic connector. This input supports AES3/EBU, S/PDIF, IEC60958, EIAJCP1201 protocols with 32KHz, 44.1KHz, 48KHz, 96KHz sample rate. The digital input does not require any special setting since Poseidon can recognize the injected digital signal and configure it automatically.

Poseidon integrates a top quality digital stereo enhancer featuring all the settable parameters needed to reach the acoustically desired effect (Effect Depth, Effect Band, Effect Level). The stereo enhancer inside Poseidon allows maximum expression of the stereophonic effect. Because the stereo enhancer is built-in to Poseidon, all parameters are controlled and optimized to assure maximum modulation stability and a 3-D sound effect.  The MPX (composite) stereo generator inside Poseidon is completely digital, so the MPX signal is obtained through DSP. Nicom offers radio stations a top digital technology solution by integrating a digital stereo generator into the audio processor instead of the widely used analog one. The stereo generator inside Poseidon increases its performances by directly processing the digital signal and ensuring perfect modulation control, while an external analog stereo generator, inserted in the chain, would adversely affect the original sound signal. The top performances of the stereo generator inside Poseidon makes it on of the best on the market at this time.

Poseidon has an optional digital RDS modulator which ensures top performance as compared to analog RDS generators now available on the market. The RDS programming is achieved through the Poseidon software in the custom made RDS page. The available services are listed in the technical specifications.  Nicom is now able to replace the cumbersome analog equipment, which has always been necessary in the past, with the Poseidon, presenting to radio stations an all digital audio chain and the purity of digital sound.
