Kuzma Stabi M 130524 - Manual (Page 3)

General
STABI M is a modern turntable designed in a classic turntable style with the emphasis on
providing the best possible record playback.
The turntable's size allows even 12 inch tonearms to be mounted and covered with its massive
acrylic dust cover on spring hinges. The dust cover is constructed not to pick up any vibration
from loud music.
The turntable is assembled from various solid parts of aluminium, making the construction
rigid and absorbing vibration. On the outer sides of the main structure are solid aluminium
plates, which give the turntable mass and further increase structural rigidity and damping.
The covered spikes within the legs allow horizontal levelling of the whole turntable.
The top aluminium plate under the platter, has an elastically underhung main frame and
motor system below. This is insulated from the outer main turntable's structure via four big
elastic dampers, which allow for fine horizontal levelling of the platter and tonearm.
The platter is constructed from two pieces of 40mm thick aluminium with an acrylic
damping plate sandwiched between making a very inert support for records.
The bearing has an inverted shaft with a ruby ball which gives precise, low noise rotation to
a supporting subplatter.
The main frame carrying the main bearing and massive aluminium armboard, is bolted
together from solid aluminium blocks forming a unique damped rigid support.
The motor system: The DC motor itself is specially mounted inside a brass cup and
aluminium plate. This motor assembly is enclosed and suspended inside a massive brass
motor housing. Thus the main frame is doubly insulated from the motor system and yet
still maintains rigidity, allowing for max. torque momentum to be transmitted via the stiff
plastic belt to the subplatter. This gives the platter a high torque drive with the positive
properties of belt and idler drives, while minimising the negatives one.
The external power supply: This controls the DC motor with precise frequency and it has
very fine speed adjustments. The control panel on the front plate of the turntable has
start/stop and speed change functions. The full speed of platter of 33rpm is reached in just
over 3 seconds. There is also a remote control start/stop function.
