The
Finest Tuning Equipment Money Can Buy.
Strobe
Center 5000-II
The
Peterson
Strobe Center 5000™....
is the most advanced tuning device ever developed. This
easy and fun to use tuner links the proven 12 window
strobe-tuning method to precision microprocessor digital
and motor control technologies, providing a versatile
tuning instrument with unsurpassed accuracy and features.
Its simple and intuitive operation makes it a pleasure to
use for all music educators, music students, musical
instrument maintenance professionals, manufacturers, and
other users with precision tuning applications.
The Strobe Center™ 5000 II is the
newest in the line of digitally-precise, 12-wheel (one
strobe per scale note) tuners produced by Peterson
Electro-Musical Products, Inc. These tuners permit
hands-free, instantaneous imaging
of note pitches as well as
simultaneous viewing of harmonies
and overtone frequencies in sounds. In addition,
programmable and preset
alternate temperaments and piano stretch tunings
make the SC-5000 II a truly universal tuning
device.

The
SC-5000 II includes the following hardware and
software enhancements over the original
Strobe Center 5000 12-wheel
tuner:
• Improved Image Clarity
- Changes in signal conditioning circuitry provide a
"cleaner", more random, blank image when no specific
acoustic input is sounding and a clearer "stopped image"
when a tone is present
• Factory-Preset Piano Stretch Tunings Included
- The SC-5000 has always permitted the creation and storage
of stretch files for use in tuning pianos, harps, steel
pan, and other instruments. Now 8 factory preset stretch
files—spanning from spinets to concert grand
pianos—have been added to greatly reduce or eliminate
the activity required to make use of this feature for piano
tuning
• Air Filtering and Fan Cooling Enhancements
- Air for cooling is now blown in through a snap-on fan
filter to help maintain long-term motor life. The filter is
easily removed for cleaning or replacing. Other cooling
system changes have noticeably reduced the overall amount
of "run noise" or acoustic noise that the unit produces
when running. This, in turn, permits clearer strobe images
at lower dynamic levels
• Automated Contrast Control and Easier Clarity
Control
- To accommodate wide variations in dynamic level, the
previous incarnation of the SC-5000 provided a 16-level
user control of contrast. This function is now internally
automated to make optimum viewing much more simple and
straightforward. Optimizing for very high or low frequency
sounds is still under manual control but is now a "one
button" operation. In addition, electronic filtering
advancements greatly reduce the need to ever exit the "HI"
clarifier selection (which is the factory power-up default)
• Fast Cent Value Advancing
- Beginning with software revision 1.05: While controlling
either global cent offset in the RUN screen or individual
note offsets under the File menus, pressing both the UP and
DOWN arrow buttons simultaneously will provide an immediate
"reset value to 0" operation. When either button is
depressed and held to continuously increment or decrement
these cent values, advancement will proceed, after one
initial step, at 5 times the currently set resolution.
These new features help to speed manipulation of the cents
parameter
The
SC-5000 II still includes all these useful features
found in the original SC-5000:
• Easy Transposition to the Key of C
- Strobe patterns appear at the correct note for all
instruments in B b, F, E b and C
• Selectable +2/-1 Pattern Shift for Upper and Lower
Register Notes
- Shifts the strobe patterns into the more visible middle
ranges. Bass notes are lifted 2 octave bands, and treble
notes are dropped 1 octave band in the strobe displays
• Digital Fine-Tuning Pitch Control for Precise
Measurement of Intonation Accuracy
• Tuning Accuracy Better Than 1/10 of 1/100
