D1-AMPS

D1 AMPLIFIERS with “ASP”
D1 amplifiers are Class-D High Efficiency Power
Amplifiers with fixed Loudspeaker Management
included. D1-series features latest technology in Class-D
amplifier design including extremely high fidelity sound
with frequency-independent harmonic distortion
performance, high efficiency design and very low total
weight. Speaker preset filters are done in analog domain
(ASP = Analog Signal Processing) resulting in zero
latency, wide bandwidth and natural transparency.
All D1 amplifiers are fitted with user variable speaker
specific presets for specific loudspeaker including
high-pass and low-pass filters, parametric EQ and very
transparent optical limiter circuit. Filters can also be
bypassed if additional DSP is used such as aux outputs
of D80DSP.
All models are powered by auto mains voltage sensing
switch-mode power supply with over current and over
voltage protection system and optimized cooling
system.
