Digital amplifier modules from CAD AUDIO DK

CAD AUDIO DELTA series analog/digital amplifier modules is a new development in audio amplifiers designed to raise the bar of performance among digital amplifers as such.

CAD AUDIO DELTA series are sort of a hybrid amplifier with an analog input/frontend, analog output, analog feedback and a switching amplifier "inside", this gives several advantages like the high efficiency know from class-d amplifiers and the true hifi audio quality mostly associated with good linear amplifiers.

15 Hz til 30 kHz power bandwidth (- 0.5 dB) largely load independant , <0,05THD+N, -100 dB noise floor, square wave reproduction like a good analog amplifier , high damping factor, very low noise etc etc
They operate from 2x15V and upwards and the dont need an aux 12v supply.

EMI and RFI are excellent (unlike other types) , the amplifiers and completely stable with or without load and will drive a 2 ohms load without problems. The amplifiers have protection circuitry to protect the amplifier and the load but no protection like current clippers or other that degrade the audio quality.

And the most important part , true HIFI audio quality where you dont have to choose between dull and boxed-in sound (like you-know-who) or more agressive and squeaky sound (like you-know-who).

We wish to challenge designers of digital amplifiers; design and build an amplifier that outperforms or just equals our DELTA type amplifiers in terms of specs,performance and audio quality.

DELTA amplifier modules can be powered from a linear or a switch-mode power supply, with their high power supply rejection its not critical at all.

Of course these amplifiers are also suited to a range of professional applications and we plan to use them in our DPA rack amplifiers , and in our DSA speaker amps and we will also offer the designs for licensing.
