Turntable Maintenance
The platter bearing is lubricated and ready to play out
of the box. After a year of use, it is recommended that
white lithium grease be applied to the ball bearing on
top of the spindle. To do this:
•
Remove the turntable belt and carefully lift and
remover the platter.
•
The ball bearing will be visible on the top of the
spindle.
•
Apply a small amount of white lithium grease.
•
Replace the platter and belt.
•
The belt will align itself when the platter turns.
Clean Your Stylus
Peak performance is achieved by maintaining a clean
stylus and record surface. A quality record cleaner and
stylus brush is recommended. If your records are kept
clean, brushing your cartridge will suffice to remove
accumulated dust if it is used after each play. Be sure
to either turn the volume down or select a different
input prior to doing this. Only use a back to front
motion when contacting the stylus during cleaning.
Anti-skate
The force of the needle in the groove will cause the
tonearm to want to move (or skate) towards the center
of the record. To keep the needle properly centered
in the groove an opposite force is applied. This is
called anti-skate. Your MTI100 is set up with properly
adjusted anti-skate. Make sure the thin cable passes
through the metal loop projecting out of the tonearm
support. There is a small gap to slip the cable in. No
other adjustments are needed.

Changing Speeds
The MTI100’s turntable motor spins at a precise
speed. Changing speeds of the platter between 33-1/3
rpm and 45 rpm is achieved by repositioning the belt.
With the turntable stationary, move the belt to the
lower, wider part of the pulley for 45 rpm. For 33
rpm, seat the belt just above the wider section.

Input Knob
Turning the Input Knob will scroll between five
possible inputs. An LED light will illuminate on the
current choice. Input choices are:
• Phono (PH)
• Bluetooth (BT)
•
Digital Coax (COAX)
•
Digital Optical (OPT)
•
Auxiliary RCA (AUX)
Volume Knob
Turn clockwise for more and counter-clockwise for
less volume. The volume will be set at the same
level as when the unit was turned off though near
maximum volumes will be scaled back to avoid
possibly unpleasant surprises. When the volume is
at the minimum setting, the MIN LED will light.
The MAX LED will light when the maximum
volume is achieved.
Pushing the Volume Knob will toggle the Mute
function on and off. When Mute is engaged, the
MIN light will flash. Remember, Pushing and
Holding the Volume Knob will place the MTI100 in
Standby when the unit is on.
About Those Tubes
The Preamplifier section of the MTI100 features
two tubes that can be seen glowing on the right of
the turntable. These tubes (12AX7 to be precise) are
expertly incorporated into the preamplifier circuit to
provide warm detailed playback.
