Isolation Base + Power Conditioner = Immediate Sonic Upgrade
PS Audio's PerfectWave PowerBase is a new product concept that combines an isolation base and a power conditioner together in one elegant component.
The tendency of all equipment to act like a microphone and re-amplify a delayed ghost image of what's playing on the loudspeaker is called microphonics. The audible effects of this ghost image are a loss of focus, decreased separation of massed instruments and voices, and a general smearing of the image.
Audiophiles have spent countless hours trying various cures, including cones, feet, spikes, platforms, bricks and discs. The PowerBase takes a different approach to vibration control by engineering a holistic multi-tiered system that includes both vibration dissipation and masking.
An Effective Approach to Vibration Dissipation
The key to effective mechanical isolation is to use multiple subsystems tuned apart by a magnitude difference, which dissipates the vibrational energy over a fairly broad spectrum. The PowerBase achieves this ideal by using two subsystems separately tuned apart by a factor of ten.
The first subsystem in the PPB is the base and suspension system itself. High durometer (very stiff) adjustable Sorbothane feet are attached to a specially damped 16 gauge steel and aluminum bottom chassis that forms the first level of energy dissipation in the system.
Mounted inside the base chassis is the second subsystem, formed from low durometer (soft) Sorbothane feet supporting a massive 20 pound damped 1/4" steel plate that forms a floating platform the equipment sits on.
The combination of a soft suspension supporting a high-mass floating platform coupled with a stiff suspension lower-mass body form a broad spectrum mechanical energy dissipation system that is extremely effective at reducing induced vibrations from the loudspeaker pair.
Vibrations generated in loudspeakers travel through the solid surfaces of the room as well as the air and induce ghost images in all the equipment in the room. The PPB can dissipate a broad spectrum of energy sent through solid surfaces in the room (such as the floor) through its double diffusion suspension system, but equipment sitting on the PPB is still exposed to airborne vibrations. This is also true for just about every isolation reduction product on the market today.
The PowerBase addresses airborne vibrations in a unique way that has proven to be quite effective. The PPB's massive floating equipment platform is designed to effectively couple any unit sitting on it to the diffused vibrations from the loudspeakers. This may at first seem counterintuitive to engineer the platform to actually couple the diffused vibrations rather than reduce them, but the design has effective purpose and improves system performance rather well.
Because it is nearly impossible to isolate the equipment in the room from airborne vibrations, the next best cure is to mask the effects of the delayed ghost image.
Masking is a simple system of adding back randomized noise to the signal. Our ear/brain mechanisms tend to ignore random uncorrelated audio in favor of correlated direct sound. In the same way that room diffusors work to enhance the stereo image and dither works to increase the apparent low level detail in digital music, coupling the diffused mechanical vibrations back into equipment sitting on the PowerBase helps mask any airborne vibrations picked up by your stereo system.
Complete Vibration Control
By combining both the mechanical vibration reduction system and tuned masking system in the PowerBase, the audible results are immediately obvious. Noticeably improved separation of instruments and voices from within the soundstage as well as a clear reduction of smearing and grunge in the music gives a new level of clarity and musicality rarely achieved with equipment in the same room as the loudspeakers.
Even the most exotic vibration control systems lack effective power cleaning facilities built into them and require an additional chassis, power cables and more.
AC power problems are inherent in both the wall voltage as well as the equipment itself. What's needed to improve the power is an effective one-way-gate that reduces power line differential and common mode noises and distortions at the source. The closer to the equipment, the shorter the connecting power cable between the equipment and the power filter, the better the sound quality of the system.
PS engineers designed a new low impedance passive common and differential mode filter that's built right into the PowerBase. Using large core magnetics and heavy gauge, low turn OFC windings, reductions of power line noise greater than 40dB can be achieved. The results are like a breath of fresh air to your system.
Power Problems Generated at the Wall
We're all aware that the power in our homes is never perfect and many times a detriment to the sound quality of our music systems. Noise from outside sources such as cell phones, satellite transmissions, computers and household appliances are polluting our power and being fed directly into our sensitive audio and video equipment. Lowering the level of induced power line noise and distortions without sacrificing dynamics and musical life is a challenge for any power filter, but the engineers at PS Audio have decades of experience tackling these issues effectively.
The power filter specially built into the PowerBase will not only restore life to your music through line noise reduction but will actually improve dynamics as well. Cleaner, better bass, lower noise and improved dynamics.
Power Problems Generated by the Equipment Itself
Not as many of us are aware that our own equipment can sometimes be our worst enemy when it comes to adding back power line grunge, but it's true. With few exceptions the power supplies in our equipment kick back current spikes and generate power line noises that can pollute other connected products on the same home power system. To effectively reduce their cumulative effect, PS engineers built a one-way-gate power filter for both common and differential mode noises generated by the equipment.
An Elegant Component-grade Solution
Think of the PowerBase as a double whammy for your system. It cleans up both mechanical and power line problems all in one elegant product that will stand the test of time for years to come. Performance levels of connected equipment will be immediately upgraded in terms of openness, spatial improvements, and a reduction of grunge and smearing.
