Introduction
The NuForce DDA-100 is a Direct-Digital Integrated Amplifier that marks a new juncture in digital sound.
The innovative new design converts the digital audio signal into analog form at the last possible stage—
the PWM amplifier output—giving listeners the same level of performance as far much more expensive
audio gear. The DDA-100's inherently low distortion and noise floor remain in the digital domain from
beginning to end, resulting in a remarkably wide dynamic range, crystalline clarity and amazing detail—all
for an affordable price.
The DDA-100 doesn't require the typical DAC stage found in most of today's digital audio
products. Rather, its PWM power amplifier stage is modulated directly by the incoming signal, and the
digital-to-analog conversion takes place at the speaker outputs. In effect, the PWM power amplifier stage
operates as a power DAC.
This effectively eliminates the DAC-related problems that have plagued serious listeners in the
past. Fewer parts result in a more direct signal path, resulting in benefits passed along to you: exquisite
sound at an affordable price.
Features:
l
96kHz input sampling rate.
l
3GB/s over-sampling rate for smoother, more natural reproduction.
l An on-chip clock reference signal for synchronizing incoming digital audio data. Data re-clocking
results in ultra low jitter performance.
l
100% linear frequency and phase response (+/- 0.1dB from 20 to 20kHz).
l
Signal-to-noise ratio > 95dB A-weighted
l
High-quality, audio-grade parts throughout.
l
Accepts four digital sources via one USB, one coaxial and two optical inputs that provide exceptional flexibility
for your home audio and A/V needs.
