6.0) USING YOUR NOVA III
If you have followed the above instructions along with mastering the following two
user options, your Nova III is ready to play music. Simply cue down your cartridge
on a favorite record, select the correct input on your receiver, integrated amp or
pre-amp, and slowly bring up the volume level. Then sit back and enjoy the music.
6.1 Subsonic Filter
Some records have sonic components due to cutting artifacts or off center "center
hole" that are low in frequency and causes woofers to move at a worrisome way.
These subsonic components can cause distortion such as "Doppler Shift".
Implementing a subsonic filter usually involve adding quite a lot of electronics which
can degrade the sonic integrity. The Nova III has a very novel implementation of a
subsonic filter where a subsonic filter is implemented with OpAmps, but the audio
portion of the signal is "stolen" from the OpAmps before the OpAmps can degrade
the signal but the low frequency noise is already removed. This "stolen signal" is
then amplified by the Nova III's discrete circuitry. This allows the Nova III preamp
section to pristinely amplify the signal.
The Nova III has a button for alternating between Normal and Subsonic Filter
modes.
The system automatically mutes when the Subsonic filter is activated or is
deactivated. This is a 5 second mute.
The LED indicates the Subsonic Filter is activated.
6.2 Mute Selection
The Nova III has a button for alternating between Normal and Mute modes.
The LED indicates the Mute Mode is activated.
The Mute Mode cannot be changed if the Mute is activated automatically by the
Subsonic Filter selection. The user must wait approximately 5 seconds for the
automatic mute to change back to unmute automatically.
