The Orion-462dsp is the processor that many AM and
FM radios were looking for to enter to the digital era, still having
little money. With the 462dsp an excellent audio quality is obtained,
impossible to reach with standard analogical processing.
The coverage area of your radio, both in AM and FM,
will be increased up to 50 %. The processor supports analogical balanced
inputs and digital AES-3 inputs (optional). It has dual output: MPX
out for FM transmitter and simultaneous balanced analog outputs for
It has 30 memories to store your favorites processing programs (20 preset
memories, factory adjusted to go immediately On-Air). All adjustments
can be made, in few minutes, from the front panel, using a scrub wheel
and following the instructions on the LCD panel. You can assign a password
to the system to avoid that somebody changes your adjustments. Also,
the processor has a RS232 port to connect it to a computer for remotely
commute the programs. The 462dsp replaces 10 audio processors, thus
surpassing to many digital processors of greater cost.
We have applied in this unit our 35 years of experience developing audio
processors for broadcasting, because we are the older world company,
with more experience in this field. The 462dsp is 100% digital, equipped
with several DSP units (Digital Signal Processor) that have a total
power of 2700 MIPS (million calculations per second). But, which is
more important, the 462 uses the fourth generation of DSP, that eliminates
the rough digital sound and annoying artifacts, characteristic of the
digital processors of the present market. The unit uses converters of
24 bits @ 192 KHz and the processing is made in 48 bits, to eliminate
the truncate errors that the audiophiles do not wish to listen... We
recommend you to listen our Demos of sound. You will verify that the
462 is the only processor that offers the crisp sound of the digital
technology, bringing deep bass and high stereo definition, characteristics
of the sound of hi-end Audiophile Audio Systems.
462dsp has included a digital SC-100 stereo coder with the new oversampling
technology. Model 462-AM, for AM transmitters, is mono and has two independent
balanced XLR outputs for main and spare transmitters. It complies with
the NRSC-1 and NRSC-2 recommendations for AM and have up 150 % asymmetry

Blocks diagram description
Ten processing stages of the 462dsp replaces
10 audio processor units. They are:
SUBSONIC FILTER: Suppress audio frequencies below 25 Hz, to avoid
distortion on the receivers. 2-EXPANDER: Increases the dynamic range of the program signal on
the air, suppressing the background noise taken by the microphones. 3-GATED COMPRESSOR (AGC) Gated compressor
with broadband range and slow action to maintain constant the level of
audio. Free to your operators of the responsibility of continuously readjust
the level of the faders! 4-PEAKSIMETRIZER
Works based on Khann-Bonello criteria. It duplicates the radiated
power for the human voice, avoiding the asymmetry produced by effect of
the vocal cords characteristics. 5 - MULTIBANDCOMPRESSOR: Operates
in 4 bands, increasing the loudness perceived by ours ears. It grants
strenght sensation and loud and solid sound quality. 6 - MULTIBANDLIMITERS
This limiter acts over fast peaks, working in 4 bands to reach an
inaudible action. 7 - 4 BANDSEQ: The audio equalizer
works controlling the sound energy (not the level) to obtain an effect
impossible to reach with conventional equalizers. 8 -DIGITALSTERO CODER: Our
exclusive 16x oversampling technology gives the 462 a direct MPX
link to the FM exciter.
For the first time, the ear is not able to perceive the 0,003%
distortion of the stereo coder. With 95 dB dynamic range and 65 dB channel
separation, we guarantee a digital audio quality on-air.
9-SUPERMODULATION: This technique, created
by Solidyne, is based on MPX processing, and allows to obtain up to 150%
of audio signal in each stereo channel, but maintaining in 100% the deviation
of the FM carrier.
10-Digital AES-3 In/Out Optional AES-3 digital Inputs and Outputs
with simultaneouns analog output for IBOC and DRM digital FM transmission
coder of the 462dsp also was object of a new vision, different from
the used by other great brands. In order to obtain those specifications,
that will astonish your Radio engineers, and your own ears, we have
chosen to create a new technology doing oversampling at 608 Khz, that
allows us to send very high the overtones of the MPX process, being
able to set the cutoff filters to 320 KHz (instead of conventional
67KHz). It manages a perfect phase response with 75 dB channel separation
and distortion below 0.003 %, free of alias and spurious components.
462dsp has option for digital inputs and outputs (AES3). Also have MPX
output and simultaneous analog balanced output for Internet streaming.
RDS generator is also an optional feature
old problem of the humming
due ground loops
does not exist in our processors,
because the MPX out is differential
and provides 45 dB
of hum cancellation.
facility that you will not find in any other processor is the MIC Start
input. It allows that, whenever the microphones are opened, the 462 changes
to a special VOICE program that allows obtaining the perfect processing
for the voice of your speakers. At the same time, the RS232 / USB interface
from PC allows the air automation software controlling the 462 in order
to change to one of the 30 stored programs that best fit the musical style.

transmission, with NRSC1 equalization and low-pass cutoff filter,
commutable between 7,5 kHz & 5 kHz. Both A.M. outputs allow asymmetric
modulation to increase the power and coberture of the emissions. While
the negative modulation keeps always at 100%, the positive one can vary
digitally between 100% and 150%, controllable from LCD screen. The advanced
asymmetric clipping system with double stage of Log clipping, an invention
of Solidyne, allows to increase to the transmitted power. The 462dsp/AM
fulfills standards NRSC-1 & NRSC-2 of spurious irradiation
