The 610LP combines customized parts in an ultra-refined audio circuit which is fed by a unique power supply. This over sized power supply, located within the main chassis, is housed in a satin coated, steel isolated enclosure which eliminates all traces of AC artifacts. Located within this enclosure is a high quality toroidal transformer, a 'pi-type' filter to reduce AC transmission noise and multiple stages of voltage regulation. These factors result in a power supply that exceeds the performance of a battery power supply with respect to both audio signal-to-noise ratio and voltage regulation.

A highly configurable phono preamplifier, the MOON 610LP offers selectable gain, impedance loading, capacitance loading and equalization curves, all accomplished using DIP switches found on the bottom panel. These switches are located directly in line with the circuit at optimal locations to yield the shortest possible signal path. These adjustments, in conjunction with an excellent overload margin, allow the 610LP to work with virtually any available phono cartridge.

Made In Canada.

Available in Black, Silver or Two-tone.

Design Features:

  • Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC in the audio circuit’s signal path – 24 stages in all.
  • 64 impedance loading settings from 12.1Ω to 47kΩ.
  • 16 capacitance loading settings from 0pF to 1120pF.
  • 16 gain level settings from 40dB to 70dB.
  • Selectable equalization curves for RIAA and IEC standards.
  • Fully compatible with 820S external power supply.
  • Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%.
