BASIC
OPERATING PRINCIPLE OF THE VARIABLE PITCH STOCKER MECHANISM
1.When
the Disc 4 button on the front panel is depressed, the empty stocker
slot 4 is moved into the standby position. Lightly inserting the
disc engages the rails, automatically drawing the disc into the
unit.
2.When
the disc is in the play position, the swing arm moves in to set
the magnetic clamp into place. The rails and the swing arm retract,
and playback begins.
MAGNETIC
DISC CLAMPING
The disc clamp plays a crucial role in ensuring stable rotation,
a factor that Nakamichi's extensive research has shown to affect
not only tracking precision but also, ultimately, sound quality.
In the case of the MB-75, another major engineering challenge was
the development of an effective clamping system that could be accommodated
within the restricted chassis space. Conventional car CD players
use springs or other means to hold the rotating disc in place with
friction. Unfortunately, such methods enable harmful vibrations
to be transmitted from the chassis to the disc. The MB-75 employs
a novel Magnetic Clamping Chuck. This magnetic clamping system has
no direct contact with the chassis. The disc is effectively isolated
from external vibrations, resulting in precise, pure signal readout.

MOBILE CD
PLAYBACK WILL NEVER BE THE SAME
Playing a CD in your car has always involved compromises. You played one
disc at a time with an in-dash unit. Or, if you wanted multi disc playback
capability, you installed a separate changer usually inconveniently located
in the trunk. Nakamichi brings you good news: Those days are over! The
MB-75 is the world's first in-dash receiver with an integral 6-disc CD
changer.
YET ANOTHER
MUSICBANK
Nakamichi Mobile MusicBank changers have revolutionized automotive
CD playback. The MusicBank changer has done away with the loading
tray altogether, adopting a slot-loading mechanism that has brought a
new level of convenience to car CD changer operation. Furthermore, successive
generations of the MusicBank mechanism have brought about significant
reductions in size and complexity. With the introduction of the MB-75,
Nakamichi brings about yet another new era in mobile CD reproduction.
Its innovative design will forever change the way most of us will play
CDs in the car. Designed to fit into a standard single-DIN dashboard slot,
the MB-75 incorporates not only the changer but also a full-featured AM/FM
tuner and a 4-channel high-powered amplifier.
DIRECT LOADING
MECHANISM WITH PARTIAL EJECT
Using the MB-75 couldn't be easier. Nakamichi's proven and highly refined
Direct Loading Mechanism ensures convenient, reliable operation without
magazines or trays. Worried about your CDs? Don't be. The MB-75's MusicBank
mechanism handles them only by their edges, whether they are being moved
or stored within the changer. There is absolutely no contact with the
disc surface. There is even a unique Partial Eject feature for added disc
protection and operating convenience. With conventional slot-loading players,
pressing the eject button forces you to grab at the exiting CD. It's easy
to inadvertently touch the playing surface. To prevent such occurrences,
the MB-75 only partially ejects the disc. When you're ready to retrieve
it, you simply give the protruding edge a gentle push. The CD is then
fully and smoothly ejected, enabling you to secure it in the recommended
manner by the center hole and the edge.
The MB-75 MusicBank Mechanism in Action
3-D VISCOUS
SUSPENSION
Even the smoothest of automobile suspensions can't prevent shocks and
vibrations from reaching a dashboard-mounted CD player. Accordingly, the
MB-75 changer mechanism is protected by a sophisticated 3-D Viscous Suspension,
which provides extremely effective vibration absorption in all directions.
It prevents degradation of sound quality and virtually eliminates skipping
and muting.
ANTI-ROLL
SUSPENSION
What
if you're dashboard mount isn't perfectly horizontal? With many in-dash
CD players, you have to make cumbersome and time-consuming spring adjustments
to accommodate non-level mounting. Not so with the MB-75. It incorporates
an advanced Anti-Roll Suspension system that permits it to be mounted
at angles of up to ±30 degrees from horizontal without any adjustment.
Moreover, all disc position detection within the changer mechanism is
handled by optical sensors. Disc change and transport functions are thus
controlled with micron-order precision, assuring reliable, trouble-free
operation.
