High-end stereo amplification
Build to perform at a very high audiophile level, the PM14mkII now has a even more stable power amplifier by using the current feed-back power amplifier. Difficult loads are driven easily and with perfect control. Resulting in an amplifier that equals the highest achievements of Marantz designers and engineers.
A lot of problems occur during audiosignal transportation from source to amplification. To decrease the rise of disturbance, our reference PM14 has the option of balanced input connections. The audiosignal is than transported twice with opposite phase. Difference signal of both signals represents the original audio signal. If disturbance occurs, both signals will be disturbed in the same way but the difference signal remains te same. The disturbance does not affect the original audio signal.
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, including separate L/R solid heatsinks. Rigid die-cast chassis and solid metal construction creating an anti-resonant environment.
Relais switched input circuit
Audiosignal switches are extremely vulnerable for dust, causing distortion of the original signal. In general switches and soundcontrols are common sources of noise. Therefore Marantz is using special Relais Switched Input Circuits. These Relais are electronic switches with high quality contacts in a dustfree environment. A pure and noise free audiosignal is the result.
Linear drive power supply
Marantz' Linear Drive Power Supply (LDPS) makes sure that there will always be enough power available to drive the speakers even with the very highest dynamics. The LDPS also enables the amplifier to drive difficult speaker loads.
Toroidal Power Transformer
The power supply of any amplifier is like the heart of the product and is therefore the most expensive to produce. Therefore for all Marantz premium products Toroidal Power Transformers are used. These transformers have a higher efficiency then ordinary laminate designed transformers coupled with the advantage of extremely low electromagnetic radiation. Therefore noise and hum into surrounding circuitry is reduced to the absolute minimum. The sonic result speaks for itself.
Only the best is good enough! In order to use equipment from several brands together in one system, the audio industry made a signal pre-out standard. To convert the audio signal to this specification, every audio device has been equipped with Op-amps (operational amplifiers) for which integrated circuit are commonly used. Unfortunately these IC's do not match the very high requirements of Marantz. Marantz developed it's own discrete circuitboards. These HDAM's consists of discrete surface mount components with short mirror image L/R signal paths. These devices are doing exactly the same thing as the Op-amps, but outperform the regular integrated circuit Op-amps dramatically in terms of the Slew Rate, resulting in a much more dynamic, accurate and detailed sound.
Current feedback power amplifier
Unlike conventional Voltage feed back amplification, the Current feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.
Active 2 Gang Volume control
Active two gang Volume Control circuits ensure the best possible signal-to-noise ratio at normal listening levels. The active circuits, with negative feedback loop, adjusts gain relative to volume level, so that noise generated by the amplifier is reduced accordingly. The absence of active circuitry in most mainstream amplifiers means that lowering the volume level the noise level is unchanged.
WBT speaker terminals
WBT is a specialised company which is fully dedicated towards designing and producing high quality audio connectors. Their products are fully accepted as the reference for audiophile products. For this reason Marantz equips our premium products with WBT connectors.
Marantz amplifiers offer music reproduction in the purest form, right from the moment the device has been switched on. However for maximum performance, it is suggested the amplifier is given time to warm up. The Temperature indicator clearly displays when the amplifier works at the optimal operating temperature.
