Introduction - Musical Surroundings NOVA III Owner's Manual

1.0) INTRODUCTION

Our 3rd generation Michael Yee design, the Nova III features an updated discrete,
dual mono audio circuit with maximum 65dB of gain and a new power supply
design that Yee describes as "effectively eliminating the wallwart". The Nova III
incorporates a large, regulated power supply providing greater dynamics and image
dimensionality, instead of batteries as in previous generations. Further performance
enhancements are available by adding the optional $650 Linear Charging Power
Supply, originally developed for our $5,000 SuperNova III.
Featured AUDIO CIRCUIT highlights:
• Discrete dual-mono circuit
• Super Matched Pair/Low Noise input devices
• Multiple gain settings on rear panel with 65dB maximum
• Extensive resistive loading settings on rear panel
• Improved Ground System
• Micro-processor control for Mute and Subsonic functions
• Michael Yee proprietary Subsonic filter
NEW POWER SUPPLY design:
• Super Low Noise voltage regulation
• Isolated DC to DC converter
• Dual Inductor de-coupling
• 10 x 1000µƒ capacitors for 10,000µƒ of regulation
• Made in California
The Nova III is a complete phonograph preamplifier with RIAA equalization that
amplifies the output signal of either a moving coil or moving magnet phono
cartridge to a nominal "line level". The Nova III may be used with a receiver or an
integrated amplifier. If you use separate components, a line level control unit
(preamp) is required before the power amp, since there is no built-in volume
control for the Nova III. The Nova III's power supply is external and connects to the
wall with the supplied wall mount transformer.
The Installation of the Nova III is quite simple and involves:
a) Setting the two rear panel configuration settings (one for each channel) for
Gain and Input Loading (see section 2).
b) Placing the unit (see section 3).
c) Connecting the power source (see section 4).
d) Connecting the Audio Inputs and Outputs (see section 5).
