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.
