The symbol stands for MU as that is the metal now
encasing the MT502 MK2 transformers. MU Metal is one of
the best shielding materials known. All step up transformers
are of a similar design. They have two transformers inside
to step up the low level signal from a moving coil cart. The
transformers are very expensive to manufacture, that is the
reason for the high prices of such items. Our transformers
are hand wound, potted, encased in an all MU Metal chassis and then placed into a copper chassis that has been gold
plated. This is all done one at a time, by hand.
CONNECTION:
INPUT: RCA's for connection to your turntable with moving
coil cartridge.
OUTPUT: RCA's for connection to a phono preamp with
RIAA equalization.
LIFT/GROUND SWITCH: This switch connects or disconnects the ground connection between the INPUT and OUTPUT RCA's. This might be useful for reducing ground loops.
SET THE SWITCH IN THE POSITION THAT SOUNDS
BEST.
TURNS RATIO SWITCH: This switch will allow you to select
between a low output moving coil cart and a very low output
moving coil cart. The 12:1 is designed to work with carts like
the Denon DL103 or 103R or similar. The 30:1 is designed
to work with carts that need more gain/level. The turns ratio
switch can be set to wherever you feel it sounds best. If you
have a higher output cart be careful not to confuse a level increase from the 30:1 setting with proper frequency response.
The 30:1 will make your cart louder. The MT502 or any cart
you connect to it will not ever be damaged by setting the
ratio switch in either location.
GROUND POST: For connection of your turntables ground
wire. In some cases the turntable ground wire might have
better results if connected directly to you phono preamp
bypassing the ground of the MT502. Try both ways and see
what sounds better.
Thank you for purchasing the MT502. We spent a considerable amount of time designing and developing the MT502.
Hundreds of hours listening and improving the design. We
hope you enjoy using the MT502, and that it makes listening
to your music collection rewarding. We sincerely appreciate
the opportunity to build a product for you and participate in
your love of quality music and sound. We love what we do
and we’re happy to help. All Bellari products are hand built in
Salt Lake City, Utah by people who care about high quality
music.
The MT502 is a moving coil to moving magnet transformer.
It converts low impedance output moving coil cartridges to a
higher impedance output for use with moving magnet preamps.
