MOON 750 D Digital-to-Analog Converter / CD Transport
Introduction
Your MOON 750D DAC / CD Transport incorporates many innovative significant design features to achieve its “world class”
level of performance. This is an abbreviated list of the more important features:
ESS Technology SABRE 32 Reference DAC/Digital Filter (ES9018S) working in 32-bit Hyperstream™ to achieve
unprecedented jitter immunity and low-level linearity via a patented Time Domain Jitter Eliminator.
Digital Audio Signal Processing using M-AJiC32 (MOON Asynchronous Jitter Control in 32-bit mode)
Proprietary CD drive system mounted on our M-Quattro gel-based 4-point floating suspension for vibration damping,
allowing ambient and spatial cues in your recordings to come to life like never before
Full unsolicited RS-232 bidirectional feedback.
Four (4) digital inputs (AES/EBU, S/PDIF, TosLink and USB) allowing for a connection to virtually any digital source
Two (2) digital outputs – AES/EBU and S/PDIF
Separate digital and analog power supplies, each with their own toroidal transformer
A virtually jitter-free digital clocking system.
Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every chip
(i.e. OpAmp, DAC, Digital Filter, etc.) in the audio circuit’s signal path – 24 stages in all.
Optional external power supply available in the near future.
Four-layer pure copper circuit PCB tracings; The advantages include better ground and power supply circuit layouts
resulting in a much shorter signal path and dramatically improved signal-to-noise ratio.
Extremely rigid chassis construction to minimize the effects of external vibrations.
Accurate matching of the very finest quality electronic components in a symmetrical circuit design.
Designed to be powered up at all times for optimal performance.
Low operating temperature for a longer than normal life expectancy.
Installation & Placement
The MOON 750D Reference DAC / CD Transport is very heavy. It requires reasonable ventilation to maintain an optimum
and consistent operating temperature. Consequently, it should be placed in a location with empty space around it for proper
heat dissipation. As well, it should be placed on a solid level surface. You should avoid placing it near a heat source or inside a
closed cabinet that is not well ventilated as this could compromise the DAC / CD Transport’s performance and reliability.
In the event that the surface you have chosen isn’t perfectly level, each of the four (4) cones on your 750D are height
adjustable; carefully using your fingers, you can either raise each leg by turning the cone underneath clockwise, or lower each
leg by turning it counterclockwise.
We strongly recommend that you leave these cones mounted to the component at all times for reasons related to both
performance and aesthetics.
