design and develop high-quality Class-D / PWM amplifiers and Switch-Mode
power supplies for use in a broad range of consumer and pro-audio
New DELTA SERIES .
Recently we have developed a new series of pwm amplifiers called the
Delta-series taking class-d amplifiers a step forward in audio quality ,
also compared with good linear amplifiers.
It is sort of hybrid between analog and switching amplifiers, input stage
is discrete class-d, modulator is discrete delta/sigma modulation, drivers
are high voltage and high current drivers, output is after the filter and
is again very analog in nature.
Frequency response is linear from 10Hz to 30 kHz and is widely independant
of load impedance, noise and THD is very good , EMI is very good, square
wave response is very good, like a good analog amplifier.
We focus here on the DELTA series of amplifiers, and we offer them as
ready made modules, modules made OEM or as designs for your own
production, contact us for more details and pricing.
Audio quality and reliability is the best in the business and our
designs meet the EMC requirements of today.
We offer these designs as "of-the_shelf" designs or as custom designs if
you require specs and features not allready found in the existing designs.
We can offer the designs as board designs for your own casing or we can
offer "turn-key" designs including metalwork design, cases etc.
Digital Signal Processing DSP
We offer custom designs for DSP boards with very high audio
performance, as an example 1-2 inputs, 4 outputs, crossovers, eq, delay
We offer of-the shelf designs or custom designs for
PWM amplifiers from 100W to 5000W pr channel , half-bridge and full-bridge designs
Combo-boards with PWM amplifiers + switch-mode supplies from 250W to
4000W or more, half-bridge and full-bridge designs
including bi-amp designs with active crossovers etc.
Multi-channel amplifiers , like 4 x 150W , 6 x 150W , 4 x 300W , 6 x 300W
The amplifiers can be combined with SMPS (switch-mode supplies) , either
on-board or as a separate board, same applies to PFC and DC-DC converter.
Mode Power Supplies (SMPS)
We offer designs for
Switch mode power supplies from 250W to 3600W,
half-bridge and full-bridge.
Factor Correction (PFC)
3600W power factor correction board
Switch Mode Power
Supplies with power factor correction (SMPS/PFC)
switch-mode power supplies with power factor correction
DC-DC converters ,
DC500 12V input , 2x60V DC output , 500W
All designs come with schematics, pcb layout, gerber files, bom and
calculated manufacturing cost/unit.
