Lyngdorf Audio MkIV Stereo Amplifier User Manual


 
- 7 -
Introduction
Lyngdorf Millennium is the world's first true-digital power amplifier where digital audio data
is converted directly into sound without analog amplification or conventional low-level D/A
conversion involved at any step.
The core technology is based on patented EQUlBlT™ processing and output modules.
The Lyngdorf Millennium is a modular design, a platform for state-of-the-art music
reproduction. This means that you can add functions or upgrade the performance, as the
technology becomes available. This manual will expand together with your Millennium. If
you take the time to register your investment, we guarantee that you will get information
about future upgrades and expansions.
Features:
Hardware:
Clocking of the PWM modulator is running in master mode at increased sampling
frequency which insures optimal performance in the audio band compared to other
implementations
Ultra low phase noise / low jitter clock system extends the dynamic range and gives
extremely low jitter
All digital signals on the PCB are noise optimized regarding transmission line load
to reduce interference to clock systems.
Built in Audio DSP’s for Equalizers, crossovers delays etc.
New Digital transceiver supporting 192kHz single wire interface
New Asyncronous Sample Rate Converter with internal conversion rate always
clear of 1:1 conversion problems.
Optimized low jitter clock system
PC interface for programming, control and upgrades
High-end Balanced DAC line out for active system setup
Performance:
THD+N level -107dB A-weighted both channels driven at -60dB@1kHz
THD+N level -104dB with both channels driven at -60dB@1kHz
THD+N < 0.01% @1kHz 10W in 8 Ohms (<0.02% from 1-150W)
THD+N < 0.015% @100W from 20-20 kHz
Dynamic range 107dB digital plus 26 dB PSU variation - totals 133 dB
DAC line out Dynamic range 116dB A-weighted
DAC line out SN+THD ratio -105dB @ FS -1dB Output Both channels driven @
1kHz
DAC linearity 20-20kHz +/-0.02dB
ASRC THD+N -140dB (20Hz-Fs/2) Dynamic range 144 dB
Software:
PC Interface for control of all built in functions, remote accessible via RS232
interface. Firmware upgradable from PC, DSP control software.
8 Presets with full storage of all filter parameters for A/B testing, different seating,
music modes etc.
20 band Parametric Equalizer and delays up to 7 meters per channel.
