General Use

Before playing a record, make sure that both of the tonearm VTA thumbscrews are slightly
tight.

Allow at least 20 hours of break-in time.

The motor will make some low-level noise. This will not get into the system. The motor and
bearings will become quieter as you use your Prime Signature. Place the motor on a mouse
pad for better isolation if this bothers you.

If you notice hum in the system, remove the turntable to phono section interconnects and
replace them with very cheap, standard VCR interconnects. These are well shielded and
should eliminate the hum. If the hum goes away, get quality, well shielded interconnects.

After at least one year of use the platter bearing should be re-lubed with PTFE super grease.
The motor will need to be lubricated with 1 drop of 40-weight motor oil below the black
drive pulley and right on the brass piece.

You can experiment with mats but you need to adjust the VTA setting when doing this.

Possible Problems:

Noise in the system: a hum or buzz:

o

The answer is to ground the motor and system properly. A line filter that floats the grounds will not
allow proper grounding of the phono system, the phono system must be grounded! Phono is not like
a CD player and if this is your first table or your return to vinyl after a decade or so you must
remember that phono amplification can be 1,000 times higher than CD or streaming so any noise that
gets into the system will be amplified much more. Kill the noise with proper grounding and your
system will sound better.

A pop on motor turn on or turn off:

o

In some systems the phono section is not well shielded and will pick up the EMF created by the switch
opening to turn off the turntable. If your system is like that you can get into the habit of muting (the
preferred method as you should really do that) or you can experiment with capacitors across the
on-off switch. We supply the table with a .001 microfarad cap, you can change it to a .01 microfarad
cap and it may eliminate to lower the problem to a tolerable level. A judicious grounding will many
times solve this problem also.
