PM4001 OSE

PM4001 OSE - Original Special Edition integrated amplifier

The famous in-house OSE tuning has it roots back in 1990’s. Based on a standard model we are re­examining all components to find in long and partly painstaking listening sessions the right balance of
the best components. Trying one component sometimes force to change another component that have
been previously determined. As a result, the PM4001 OSE gives tighter bass, clearer stereo images and a
wider sound stage. The original features such as phono input and two-pair of speaker connection with
the convenience of bi-wiring connection are still there. The OSE is easy to detect due to the Original SE
badge on the solid metal front and of course on the excellent sound quality.

Technological glossary:

Original SE
Our OSE products are based on exciting audio devices within
the Marantz range and are upgraded to very high standards.
Therefore our OSE products exceed every expectation. These
specially labeled products are designed with the greatest care
for construction and component use. Based on the PM4001 and
in line with our care for nature we have ensured that the
PM4001 OSE is environmental friendly as well, when disposed
of, after a lifetime of musical enjoyment. The OSE products
have really become a Marantz trademark in terms of value for
money.

Customized Components
Every Marantz product is designed with a fine ear and eye for
details. The designers have to know the characteristics of every
component. On paper the component might look excellent but
the result may fall short of the combined design expectations.
Therefore Marantz collects vast amounts of information upon
specifics component performance capabilities. The result
guarantees Marantz selects the appropriate components for the
specific design application. The sonic result is critically
acclaimed by international reviewers. In other cases it's simply
not possible to use standard components that meet the high
Marantz standards. These components will then be specially
made for Marantz only in co-operation with the Marantz
engineers.

Symmetric circuit architecture
To achieve the best possible sonic performance, signal paths
need to be short, direct and mirror imaged. The construction of
our circuitry provides improved stereo image by ensuring
symmetry between right and left channel layout. The tone
defeat circuit will insure shortest signal paths by passing tone
control board completely. The rigid chassis, solid metal
construction and solid metal front create an anti-resonant
environment.

Special selection of audiophile components to give the best
possible sound quality
Minimizes mechanical vibrations which can disturb the
sensitive audio signal
Sufficient real power capability to fill the room with musical
enjoyment
Listen to one source while recording from another
Allows tonal adjustment to personal taste
Bypasses the tone control circuitry and ensures the purest
sound quality
Two times identically lay out symmetric audio circuit
boards secure precise stereo imaging
For bi-wired connection of loudspeakers, or for multiroom
applications
Flexible system integration and total control via one system

Two pair of speaker outputs
In not all domestic environments the availability of one speaker
system is sufficient. The PM4001 OSE is equipped with the
possibility to connect 2 pairs of loudspeakers. The speaker
systems can be switched on and off by simply selecting the
speaker system on the front of the amplifier. Another option for
the second speaker connection is to provide a bi-wired
connection for your main loudspeakers. By doing so, this
provides each loudspeaker drive unit (bass driver and tweeter
unit) to have a separate and direct connection to the amplifier.
This reduces any influence the internal cross-over may exert
upon the music. In effect each drive unit has a separate and
independent filter network eliminating all crossover distortion.

In control of the system
To optimize equipment in terms of ease of use, Marantz has
designed the D-Bus system. Individual devices inform each
other, in order to automatically tune to the customers demands.
At the same time received remote control commands are
communicated via this bus. This enables equipment without IR­receiver, like a cassette deck or tuner, to be controlled via the
bypacked Marantz System Remote Controller.

Environmental friendly
Every electronic equipment product is built of single electrical
components that are made of different material and substances.
Marantz assure that the components used in our products are
free of any dangerous material or substance to keep our
environment clean. We have for example removed hazardous
substances like lead in the solder.
