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

includes 2 highly efficient Switch Mode Power Supplies with
PFC, each independently powering a set of 4 channels. The 8
output stages use the well-known Class D - full bandwith
PWM modulator obtaining ultra low distortion, high efficiency
and also equipped with a full set of circuit protections.
Designed to meet the most demanding multi-zone
application sound systems, it provides a full set of value

inputs with Phantom power supply, 8 Line outputs,
supporting a full matrix mixing mode where inputs may be
routed/mixed in any ratio to any output. also provides MDA88F
a variety of Eqs, Noise Gate function, Gain control, X-over,
RMS compressor, Peak Limiter and Delay. In addition Mic inputs
include a Feedback Eliminator, based on a powerful “Pitch
Shifting” algorithm, particularly suitable for voice applications.
Automixing function automatically adjusts input level to make
operating easier using either NOM (Number of Open Mics)
attenuation function or Gain Sharing algorithm. In addition
Ducking process enforces a "priority order" of open Mics in
order that high-priority inputs attenuate lower-priority inputs.
For remote configuration and control the can be MDA88F
connected via Ethernet, USB or RS485 by using the control
remote PC software. In addition, it can be managed by an
Apple iPad® device, using the dedicated DPA880xT software
setting all parameters and showing real time levels. For
complex systems, 8 digital IN/OUT ports are provided for GPIO
Integration. Furthermore the can be connected via MDA88F

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.

based on a precise frequency shi ft of the overal l

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

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

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

“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
