COMPANY HISTORY

The SEED began as SEED srl, based in Tuscany, Italy. It was founded by Managing Director Michele Marani a specialist developer of custom DSP applications, in 1996. Today the company has evolved into a global business with a strong R&D team composed on highly qualified engineers located in Italy and China. Currently Seed Asia Ltd owns an internationally registered Trade Mark for its own Audio Products ”MARANI” and it develops and produces all Marani Brand products related to the professional audio market. Thanks to SEED’s highly qualified team, it also produces original design manufacturer (ODM), for international clients supporting them from concept to finish product. Product sectors include: and above all innovative audio processing, focusing on HD recording, karaoke effects, guitar and amp modeling algorithms, speech intelligibility and acoustic feedback processors, professional equalizers, compressors and general effects. SEED has become a leader for electronic and product part sourcing, allowing purchasing and manufacture to be flexible in volume, with high quality control and ensuring excellent prices.

DPA2655QRT

DPA2655QRT is a high performance 2-IN/6-OUT digital

speaker management system. Designed for maximum

versatility, it provides all the processing and control

necessary for both live and fixed installation use. Providing for

any crossover configuration, it offers 2 analog inputs, 6

analog outputs and a digital S/PDIF input, managed by a

powerful DSP Engine, in addition to high performance 24Bit

AD/DA Converters. Each input channel provides a choice of

EQ with 5-band Parametric equalization, Gain control and

configurable Delay. Each output offers up to 5-band of

parametric equalization, in addition to the crossover filters

which themselves provide slopes from 6dB/Octave up to

24dB/Octave. Each output path also features RMS

Compressor, Peak Limiter and configurable Delay. The

DPA2655QRT supports a full matrix mixing mode where

inputs may be routed/mixed in any ratio to any output. For

CLP2600

CLP2600

The is a Professional Multi Band Compressor/ CLP2600

Limiter performing a compression process on 3 different

bands offering excellent sonic quality for any application from

studio recording to live sound or broadcast. It is a powerful

dynamic processor that offers sampling rates up to 48kHz,

with a 24-bit digital signal path, that can be used in dual

channel, stereo or mono mode. The has been CLP2600

carefully designed to improve the overall signal dynamic

performance with the 3 RMS compressors per channel in

addition to the Peak Limiter function to minimize dangerous

signal peaks. The True RMS level detection per each of 3

bands, provides the most natural-sounding dynamics

processing available, allowing the Compression processes to

avoid the overhead or attenuation effects around the bands

limit frequencies, thanks to different ratio, threshold or

time-constant settings in the three frequency bands.The

CLP2600 also includes Gain, Phase Control, Delay, Noise

Gate, AGC and 5-band parametric EQ per input channel,

offering unprecedented control and making the the CLP2600

most versatile and useful tool to use for any application. The

all Audio Processes are Marani proprietary algorithms,

already well known in the PRO Audio Industry. Additionally the

CLP2600 features all the best from the digital world such

as factory and user presets. Finally it can be connected via

USB and RS485 by using the control remote PC software

setting all parameters and creating favorite presets.

Eliminator performing a Feedback detection based

Notch Fi lters Automat ic p lacement for h igh end

“Musica l”app l icat ions, or a feedback El iminat ion

based on a precise frequency shi ft of the overal l

band, for high end “Vocal”applications.The DFP225

is a powerful digital feedback detection device that

can be used in dual channel,stereo or monomode.

The has been carefully designed to protect DFP225

aud io events f rom f eedback prob l ems that can

occur between loudspeakers and open microphones.

Notch Filter Mode: the system can be set up for

automatic detection, or be configured manually and

according to user settings. The feedback system

a n a l y z e s a l l f r e q u e n c i e s i n t h e s i g n a l p a t h ,

determines the cause of the Larsen ef fect and

cancels it by implementing up to 25 real-time high

steps, a l lowing the user to change the DFP225

sens it i v i ty to aud io feedback accord ing to your

situation requirements. The parameter settings of

the 25 notch f i lters per channel remain in EEprom

memory, but i f i t i s requ i red tokeep them as a

setting for future reference they must be saved in

a user memory preset. Frequency Shift Mode: in

this mode, the input signal is frequency shifted in

order to avoid the sequent “gain arise on Air”, after

the loudspeakers, due to sum of equal bands.This

method is AVOIDING the feebdack to occur, instead

“Frequency modification” introduced by the method,

alterating the original tone of the full signalband, it

is suggested to be used for Vocal applications, but

even very good a lso for musica l ones, be ing the

frequency shift actually pretty small, ranging from

1 up to 4.5 Hz, and distributed proportional ly on

the overall band, so not modifying the original ratio

between the harmonics. The frequency shift amount

can be selected by the user with continuity through

the avai lable Freq. Shift Control.The has DFP225
