Signature Rendu SE - single enclosure UltraRendu & linear power supply

Introducing the Signature Rendu SE, the absolute finest streaming USB source we have made. The Signature Rendu SE is the natural evolution of Sonore’s microRendu (computeraudiophile.com Product of the Year 2016) and Sonore’s acclaimed Signature Power Supply.

The Signature Rendu SE takes an Ethernet audio stream and renders it to a perfect, ultra-low noise USB feed to one’s USB DAC. While the microRendu is a revolutionary product, the Signature Rendu SE takes off from the microRendu concept, improving on it by refinement and attention to every detail.  The Signature Rendu SE takes advantage of a single chassis design, allowing close coupling of the power supply and processing board for the ultimate in ultra-low impedance and ultra-low noise power delivery. The Signature Rendu SE processing board uses a larger footprint to allow for more independent low noise voltage regulation stages (all main board regulators are now ultra-low noise linear types), and better physical separation of the Ethernet processing and USB output sections, further reducing noise and crosstalk. A new ultra-low phase noise (so called “femto”) oscillator is used to govern all processing and USB audio output.

HARDWARE FEATURES

• The internal power supply is a no compromise design featuring a custom wound, EI style transformer from Mercury Magnetics (made in the USA). This transformer effectively blocks AC line noise, providing a solid foundation of clean power.
• Ultra-soft recovery diodes and film capacitor damping assure a DC supply free of ringing artifacts, and massive power supply capacitance (50% more than used in even the Sonore Signature Supply) insures low impedance/low ripple power delivery to our main, discrete linear pre-regulator.
• A stainless-steel chassis divider protects the processing circuitry from both AC wiring and transformer based stray RF and EM interference.
• The Signature Rendu SE is housed in a beautiful audiophile custom chassis, (made in the USA) which is right at home alongside the finest audio components in the world.
• Upgraded custom footers with larger Sorbothane pads virtually absorbs all external micro mechanical interactions from migrating into the highly critical processor and re-clocker boards.
• Dimension: 12.75in (width) x 3in (height) x 10.25in (depth)
• Weight: 10lb
• Power input: 120VAC or 230VAC, 60Hz or 50Hz
• Power consumption: 25 VA
• Includes warranty card and manual

Foundation

4K Ultra HD Processor

The Foundation 4K UHD adds HDMI 2.0 and HDCP 2.2 technology to the
award winning Foundation processor. Designed to be upgradeable, existing
Foundation processors can be upgraded to the Foundation 4K UHD platform
at the Krell facility. The Foundation 4K UHD updates 4 of the 10 HDMI
1.4a inputs to HDMI 2.0/HDCP 2.2 capability. New on screen display
functionality adds status messages including volume, active source,
video resolution and audio format. System setup is accomplished from the
front panel or a network tablet/computer.

 

Additional functionality has been added to the second HDMI output. The
two HDMI video outputs are now independent and can be configured to send
different video signals to two individual displays. Both outputs
support 4K signals being simultaneously displayed.

 

Both HMDI outputs feature Audio Return Channel (ARC). With ARC, a
display device is able to send audio back down the HDMI cable to the
Foundation 4K UHD. Televisions with built-in web streaming capability
like Netflix or Pandora, can send the audio signal back to the
Foundation 4K UHD use the full home theater system instead of just the
TV's speakers.

 

Featuring the latest digital connectivity, the Foundation 4K UHD
maintains Krell's exacting standards for analog audio reproduction.

 

From decoding the latest lossless audio formats, extensive digital
switching, 3DTV pass-through, and more, the Foundation 4K UHD is fully
compliant with the digital age. The 7.1-channel processor also features
balanced audio outputs, automatic setup and room EQ, and Krell's
legendary robust hardware. A slim form factor exudes the Krell
aesthetic, while allowing placement in smaller equipment racks.

 

The Foundation 4K UHD features Krell's Automatic Room Equalization
System (ARES), to ensure the best possible performance from every
theater. ARES analyzes all the speakers in the system, their location,
phase, and distance from each other, to determine the best crossover
frequency, delay, and more. In addition, ARES incorporates the acoustics
of the room to determine unique EQ curves for each of the 7.1 output
channels. Unlike other room EQs, ARES can be programmed to only adjust
the troublesome low frequencies, leaving high frequencies unaltered.

 

The Foundation 4K UHD includes a new Krell development - Intelligent
HDMI switching. Intelligent HDMI switching is a combination of circuitry
and innovative software that optimizes HDMI operation. Various
parameters including the monitor's electronic ID and source video
resolution are stored in non-volatile memory. All 10 source inputs are
always active so source, channel, video resolution, and audio format
changes are instantaneous. The Intelligent HDMI design provides the
fastest signal recognition possible.

 

The Foundation 4K UHD passes video signals directly without any video
processing, ensuring bit-for-bit accuracy of the signal, up to
3840x2160. However, to simplify cabling, setup, and use, there is full
transcoding of the 2 composite and 3 component analog video inputs to
the HDMI outputs.

 

Krell designed the Foundation 4K UHD with flexibility and ease-of-use in
mind, with extensive routing capability of the audio inputs to the
various outputs. During setup, the specific paths will be chosen based
on how the user intends to use each source, displays, and audio output
channels.

 

The Foundation 4K UHD supports stereo and multichannel DSD decoding via
any of the 10 HDMI inputs. Playback options include DSD 2-ch Direct, DSD
Stereo, and DSD Multi modes. DSD 2-ch Direct converts a stereo DSD
signal to analog and directly passes it to the left and right analog
outputs. DSD Stereo first applies any left and right channel crossover
configured in the Foundation 4K UHD menu, converts the signal to analog,
and then sends it to the left and right outputs. DSD Multi supports
multichannel DSD recordings and utilizes all crossovers configured in
the Foundation 4K UHD menu. There is no configuration required as the
Foundation 4K UHD automatically recognizes a DSD signal and defaults to
the last used DSD mode for playback. Pressing the mode button on the
remote control or web server interface will cycle through all three DSD
modes.

 

The Foundation 4K UHD will allow owners to take full advantage of the
best audio soundtracks available, with decoding of Dolby Digital,
Digital Plus, Dolby TrueHD, DTS, DTS-ES Discrete, Matrix, and DTS-HD
Master Audio. In addition, a full suite of post-processing modes are
included, including Dolby Pro Logic IIx and DTS Neo 6. Krell's
proprietary surround modes, Party, General Admission, Front Row, and On
Stage, offer a different way to listen to favorite tracks.

 

The Foundation 4K UHD also offers features that make it perfect for
custom installation, such as 3.5mm jacks for IR input and 12-volt
trigger input and output, as well as RC-5 and optional rack-mount ears.
Additionally, the unit can be controlled with home automation systems
via RS-232 or the Krell web server through its Ethernet connection.

  Electrostatic Technology (How it Works): Where
  traditional loudspeaker technology incorporate cones, domes, diaphragms,
  and ribbons that are moved with magnetism, electrostatic loudspeakers
  employ charged electrons attracting and repelling each other. An
  electrostatic transducer consists of three pieces; stators, the
  diaphragm, and spacers. The diaphragm is what actually moves to excite
  the air and create music. The stator's job is to remain stationary and
  to provide a reference point for the moving diaphragm. The spacers
  provide the diaphragm with a fixed distance in which to move between the
  stators. As your amplifier sends music signals to an electrostatic
  speaker, these signals are changed into two high-voltage signals that
  are equal in strength but opposite in polarity. These high voltage
  signals are then applied to the stators. The resulting electrostatic
  field, created by the opposing high voltage on the stators, works
  simultaneously with and against the diaphragm, consequently moving it
  back and forth, producing music. This technique is known as push-pull
  operation and is a major contributor to the sonic purity of the
  electrostatic concept due to its exceptional linearity and low
  distortion.

  Hybrid Electrostatic Speaker: The MartinLogan
  ElectroMotion ESL X is a hybrid electrostatic loudspeaker that features a
  XStat CLS electrostatic transducer panel, an optimized Vojtko
  crossover, and two passive 8" woofers. Electrostatic panels are perfect
  for reproducing high, midrange, and midbass frequencies. However, both
  the size and the power requirements of deep bass frequencies are best
  served by traditional cone woofers. A phase and amplitude optimized
  Vojtko crossover (400Hz) ensures a seamless transition between the two
  sound reproduction philosophies. As a result, this speaker offers the
  best performance for high, mid, and low frequencies.

  XStat CLS Transducer:  The MartinLogan
  ElectroMotion ESL X features a 8.6" (w) x 40" (h) XStat CLS Transducer.
  This new XStat transducer builds upon the legacy of MartinLogan's
  electrostatic heritage with the incorporation of a myriad of technology
  and design innovations including CLS, MicroPerf, Generation 2
  Diaphragms, ClearSpars, Vacuum Bonding, and AirFrame technology. Through
  rigorous testing, this curvilinear electrostatic panel has proven
  itself to be one of the most durable and reliable transducers available
  today. Fabricated from a custom tool punched high-grade steel, the
  patented panel is then coated with a special polymer that is applied via
  a proprietary electrostatic bonding process. This panel assembly houses
  a membrane just 0.0005" thick. Ruggedly constructed and insulated, the
  panel is rated to easily handle 20 to 300 watts of power.

  
  
• CLS (Curvilinear Line Source): MartinLogan
  engineers discovered a simple solution to achieve a smooth pattern of
  dispersion from a smaller electrostatic transducer without degrading
  sound quality. By curving the horizontal plane of the electrostatic
  transducer, a controlled 30° horizontal
  dispersion pattern could be achieved, yet the purity of the almost
  massless electrostatic diaphragm remained uncompromised.
• Generation 2 Diaphragm: The diaphragm used in the
  ElectroMotion ESL X XStat transducer employs an extremely sophisticated
  conductive coating applied to the polymer surface at an atomic level
  using a plasma bonding process. A proprietary compound is driven into
  the surface of the polymer film in an oxygen free argon chamber. This
  process allows extremely uniform surface resistivity characteristics, an
  optically transparent surface, and a nearly massless diaphragm. This
  uniform surface resistivity controls the electrostatic charge on the
  diaphragm surface and regulates its movement.
• MicroPerf Stator: Although stators are the
  elements of an electrostatic driver that are supposed to stand still,
  they carry the audio signals that do the work of propelling the
  diaphragm back and forth to move air and produce sound. Because the
  stators sandwich the diaphragm between them, they must be perforated to
  allow sound to pass through. Yet they must also be rigid enough to
  remain absolutely stationary despite the strong electrostatic forces
  pushing and pulling at them during operation. MartinLogan's MicroPerf
  design optimizes this tradeoff by reducing the size of the individual
  holes and using many more of them than in a traditional electrostatic
  panel. MicroPerf almost doubles effective diaphragm radiating area
  without compromising structural integrity. The resulting increase in
  output capability and efficiency allows the XStat CLS panel to be made
  much smaller without sacrificing performance and lets you enjoy a
  substantial leap in bandwidth and dynamics.
• Vacuum Bonding + ClearSpar Spacers: To achieve the
  power, precision, and strength of the XStat transducer, two insulated
  high-purity carbon steel stators along with a proprietary plasma bonded
  diaphragm and ClearSpar spacers are fused into a curved geometry with an
  aerospace adhesive whose strength exceeds that of welding.
  MartinLogan's proprietary Vacuum Bonding process guarantees uniform
  diaphragm tensioning and extremely precise construction tolerances,
  resulting in precision, linearity and efficiency.
• AirFrame Technology: The XStat CLS panel is
  secured to speaker cabinet using MartinLogan's AirFrame technology. The
  extruded aluminum and composite AirFrame makes the panel extremely rigid
  while maximizing playable surface area and dipole sound radiation. At
  the same time, it provides electrical and acoustical isolation,
  minimizing intermodulation distortion caused by vibration and resonance.
  Overall, AirFrame technology enhances imaging, low-level sonic detail,
  accuracy, and efficiency.
• 
  

  Controlled Dispersion Sound Radiation: A key
  attribute of the ElectroMotion ESL X is its naturally dipolar radiation
  pattern. A true dipole, the EM-ESL X radiates sound with equal intensity
  from the front and back of its diaphragm, but the outputs are in
  opposite phase. As a result, sound waves rippling out toward the sides
  meet at the speaker's edge and cancel. That and the relatively large
  size of the ElectroMotion ESL X's electrostatic panel cause output at
  the sides to be very low relative to that of a conventional loudspeaker,
  which in turn minimizes side-wall reflections that tend to muddle sonic
  detail and stereo imaging. While the reduction in output to the sides
  contributes to the astonishing clarity, the energy reflected off the
  wall behind the speaker opens up and deepens the sound.

  Full-Range Operation: Another significant advantage
  of MartinLogan's exclusive electrostatic transducer technology is that
  no crossover networks are used above 400Hz, because they are not needed.
  The ElectroMotion ESL X consists of a single, seamless electrostatic
  membrane reproducing all frequencies above 400Hz simultaneously. This
  eliminates the crossover phase aberrations that are associated with
  traditional tweeter, midrange, and woofer systems. The result is a
  dramatic improvement in imaging and staging performance.

  Dual 8" Woofers w/ Ported Cabinet: Two precise 8"
  high-excursion, perfectly balanced, audiophile grade, doped-fiber cone
  woofers have been custom designed exclusively for The EM-ESL X by
  MartinLogan's in-house engineering team. These woofers precisely
  optimize cone suspension and magnetic flux field to produce high levels
  of bass output and simultaneous precise midrange. The custom woofers'
  rigid light-weight diaphragm eliminates cone flexure and maximizes
  response time to achieve remarkably low-distortion. The 8" woofers are
  housed in a non-resonant asymmetrical cabinet with a down-firing bass
  port for additional bass extension.

  Note: When you first begin to play the
  ElectroMotion ESL X speaker, it will sound a bit bass shy. This is due
  to the high-quality, long-life components used in the passive woofer.
  The custom-made woofer requires approximately 72 hours of break-in at 90
  dB (moderate listening levels) before any critical listening. The
  break-in requirements of the crossover components (and, to a lesser
  degree, the stator) are equivalent.

  Proprietary Vojtko Filtering: To seamlessly blend
  audio output from the high- and mid-frequency electrostatic panel to the
  low-frequency woofers the ElectroMotion ESL X features a proprietary
  Vojtko topology filter utilizing custom air core coil and low DCR steel
  laminate inductors, polyester film capacitors in series, and low DF
  electrolytic capacitors in parallel.

  Bi-Wirable Binding Post: The ESL X features
  bi-wirable binding posts and provide the ultimate level of flexibility
  for connection and setup. MartinLogan's proprietary tool-less binding
  posts simplify cable connection and management. Two sets are supplied;
  one connected to the electrostatic panel and the other feeding the
  woofer. You can choose to bi-amp the ESL X, or use jumper clips between
  the binding post sets for a single wire-connection. The binding posts
  will accept bare wire (16- to 8-gauge), pin-connectors,
  spade-connectors, and banana plugs (single only).

  Low-Voltage DC Power Supply: The ElectroMotion ESL X
  speaker uses an external low-voltage power supply to energize its
  electrostatic panel. The included power supply firmly inserts into the
  "DC Power In" receptacle on the rear-panel of the speaker and then to an
  AC wall outlet. The ElectroMotion ESL X speaker features a signal
  sensing circuit which will switch the ElectroMotion ESL X off after a
  few minutes of no music signal, and requires less than two seconds to
  recharge the panels when a music signal is present.

  Applications: The MartinLogan ElectroMotion ESL X
  floor-standing speakers can be used as stereo speakers or home theater
  front/surround speakers. The ElectroMotion ESL X speakers are ideal for
  medium and small rooms.

  Placement: The ElectroMotion ESL X speaker should
  be placed approximately 2' to 3' from the front wall (the wall in front
  of the listening position) and about 2' from the side walls. Your
  sitting distance should be further than the distance between the
  ElectroMotion ESL X speakers themselves. This will allow you to attain
  good center imaging and stage width. Generally, it is found that the
  ideal listening position is with the speakers slightly toed-in so that
  you are listening to the inner third of the curved transducer section. 

  Note: The front wall surface ideally
  should be one long wall without any doors, windows, or other openings.
  If you have openings, the reflection and bass characteristics from each
  channel can be different.

  Interchangeable Feet: The MartinLogan ESL X
  floor-standing loudspeaker includes four pre-installed rubber feet for
  tile and hardwood floors. You can remove the rubber tip from the
  pre-installed feet to reveal four metal spiked feet for carpeted
  flooring. The feet are threaded into the base of the speaker and can be
  adjusted to non-level surfaces.
