KAB SpeedStrobe
TURNTABLE SPEED TESTER
The KAB SpeedStrobe was designed to replace and improve
upon older strobe designs that relied on power line frequency. We also wanted
something that was easier to use and included the ability to actually measure
small amounts of error. Not just a go - no - go - test.
The KAB SpeedStrobe features a quartz locked illuminator
with 99.99% accuracy. And since it is battery operated, it works everywhere. No
need for 50 or 60 Hz versions. The Disc is silk screen printed on durable 20
mil PVC.
Instead of hypnotic bars, the KAB SpeedStrobe features the
actual speed numbers. In use, the desired speed is read directly from the disc.
no searching for the right band. Covers 16.66, 33.33, 45, 70.59 - 90 RPM. By
timing the drift of the display over one minute, accuracy can be measured to
0.03% Click here to read how strobes work.

Many Hi End turntables today still use hysteresis
synchronous motors which rely on the line frequency to achieve accurate
rotation. Using a conventional strobe to measure these turntables reveals a
flaw: If the line frequency is low, the turntable will run slow, but so will
the fluorescent light used to illuminate the strobe disc. Result: the strobe
may show the correct speed, even though it is wrong! There is a definite need
for an independent quartz crystal controlled illuminator.
The KAB SpeedStrobe is fully independent thereby
eliminating major sources of error. And the large disc is very easy to
read.

Measure Turntable Speed
Often! |
The really great features to take note of with the KAB
SpeedStrobe is the ease of use and absolute accuracy.
The KAB SpeedStrobe is unique in 2 ways. First, it does not
rely on line frequency like other strobe discs. We have heard our share of
stories that confirm what we have always suspected: line frequency variations
are common. And if your turntable uses a hysteresis synchronous type motor, it
will be susceptible to speed variations.
Second, conventional strobe discs use a series of hypnotic
bars that "freeze" in motion when the turntable is at the correct speed. Thats
fine for a turntable that can adjust its speed. But have you ever tried to time
those marks so you can measure accuracy? It is nearly impossible. The KAB
SpeedStrobe disc uses large easy to read numbers. It is very easy to time the
drift of this display. This lets you measure fixed speed turntables and
determine their accuracy. |
