INTRODUCTION

D2 amplifiers are Class-D High Efficiency Power Amplifiers

with fixed Loudspeaker Management. D2 amplifier range

represents the latest technology in Class-D amplifier design

featuring extremely high fidelity sound with frequency-

independent harmonic distortion performance, very low

noise floor and low total weight.

D2i is 2 in 4 out amplifier to be used as an independent

system amplifier or together with D80DSP fed by D80DSP

AUX Outputs. It is a dedicated system amplifier for i3 and

i5 with subwoofers XD10 and XD12 featuring crossover for

bi-amp operation.

D2i amplifier is fitted with fixed system controllers for the

specific loudspeaker including high-pass and low-pass filters,

parametric EQ and state-of-the-art optical limiter circuit.

Both channels are powered by separate switch-mode power

supplies featuring over-current and over-voltage protection

and optimized low noise cooling system.
