Marantz Proprietary HDAM SA3 Technology: Marantz's exclusive HDAM
SA3 technology features
precision discrete components that provide wide dynamic range with low
distortion, outperforming conventional op-amp integrated circuit chips. HDAM SA3
modules are used in the digital audio converter stages as well as the critical
analog audio stage.
Current Feedback Amplifier: Marantz proprietary
current-feedback circuit, using discrete components, is adopted in the
pre-amplifier and power amplifier section of the PM7005. Equipped with multiple high
current wide range power transistors, the PM7005 features the ability to handle
low impedance speakers, and is rated at 60 watts per channel into 8 ohms and 80
watts per channel into 4 ohms. The output stages feature current feedback
(originated by Marantz) instead of voltage feedback, for the lowest distortion
and highest stability.
High Current Power Supply w/ Short Power Line Layout: Featuring a high current high capacity
shielded toroidal power transformer, the power supply section also employs high
current high speed Shottky Barrier Diodes, along with high current storage
capacitors that together provide wide dynamic range along with low impedance
drive capability. For strong momentary current supply, a short power-line layout
unifies the power circuit and output stage of the power amplifier section. This
layout allows connecting the large-current lines via the shortest route while to
arranging the left and right channels symmetrically.
Reference Quality DAC: The PM7005 is equipped with a reference class
CS4398 24-bit/192kHz DAC for exceptional sound quality of your digital audio
sources. The digital audio section is housed in a shielded compartment to
prevent interference with the analog audio circuit blocks.
Analog & Digital Inputs: In addition to four other analog line level
inputs, the PM7005 also features a dedicated phono input, for compatibility with
moving magnet turntables. Both optical and coaxial digital audio inputs are
provided, for compatibility with a wide range of digital audio sources (2ch PCM
only; 32-192kHz). There is also an analog record output. The
analog inputs/outputs and coaxial digital input are gold-plated for optimum
USB Type-B Port: The integrated amplifier can operate as a soundcard
for your Windows PC or Mac computer using its asynchronous USB-B port and built-in DAC which
allows for "bit-perfect" support of 24-bit/192kHz and DSD 2.8/5.6MHz
high-resolution audio. The PM7005 supports Windows 7/8 and Mac OSX 10.6.3 or
later. You will need to download a dedicated
USB audio driver for Windows PC.
Audio Settings: The Marantz PM7005 offers a variety of audio setting
to improve audio performance and enhance your listening experience.
- Source Direct Mode: The Source Direct function bypasses
unneeded circuit stages (such as the tone controls) for the most direct
audio path from input to output.
- Analog Mode: If Analog mode is turned on when playing
back an analog input source, power to the digital input circuit is turned
off. This prevents the analog signal circuit from being affected by noise
generated by the digital control circuit, resulting in high quality audio
- Tone Controls: This unit has a tone control function
for adjustment of bass (low frequency) and treble (high frequency) sound to
produce your preferred sound.
CD Direct Buffer Amplifier: This is a high-speed buffer amplifier
made with discrete components, which avoids interference between right and
left channels and can send the signals to the pre-amplifier with very high
Fully Discrete Headphone Amp: For superb sound quality with the widest
range of headphone types, the PM7005 features a fully discrete headphone
amplifier that is able to handle just about any headphone type, regardless of
impedance or sensitivity. The high quality gold plated 1/4" headphone jack is
compatible with audiophile and studio headphones and adapters.
Heavy-Duty, Gold-Plated Binding Posts: The PM7005 is fitted with four
heavy-duty, gold-plated binding post terminals for long life and
optimum signal transfer integrity. The binding posts will accept banana plugs
(single only), pin connectors, and bare wire (up to 10AWG).
Aluminum/Glass-Reinforced Resin Front-Panel: The integrated
amplifier's front-panel uses a carefully chosen combination of aluminum &
glass-reinforced resin to create a distinctive three dimensional appearance.
Indirect reflecting blue LEDs indicating input selection and heighten its
Remote Control: Featuring an easy to use ergonomic design,
the elegant remote control can also be user to control a Marantz CD player or
network player (sold separately). Remote input and output terminals let you
connect the PM7005 to other Marantz components, such as a Marantz CD player or
network player, allowing you to place the PM7005 out of sight (such as in a
cabinet) yet still providing full remote control capabilities.
Protection Circuit: The PM7005's Protection Circuit prevents
damage to devices within the power supply when an abnormality such as an
overload, excess voltage occurs or over temperature for any reason. If a
malfunction occurs in this unit, the power indicator blinks red and the unit
switches to standby mode.
Auto Standby Mode: With the Auto Standby Mode "On", this
unit will automatically enter the Auto Standby Mode after approximately 30
continuous minutes of no output from the speakers or headphones.
