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. 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 SC5000II includes all the
ultimate features such as: individual strobe disc displays for the 12 chromatic
tones, pre-programmed and programmable temperaments for tunings other than equal
temperament, stretch tuning for inharmonic instruments, and a built-in condenser
microphone.
Features of the Strobe Centre 5000 II:
VISUAL RANGE: Seven Octaves
from C=16.352 Hz to B=3951.064 Hz; Eight Octaves when using the
DISPLAY +2/-l Feature.
ACCURACY: Equal Temperament
Scale, All Pre-programmed Alternate Temperaments, Built-In Stretch Tuning
Tables, User Definable Temperaments and Stretch Tuning Tables are guaranteed
to be within 1 / 10 of 1 / 100 of a semitone (1 / 10 of one Cent, or 0.006%)
KEY SELECTION: Choice of Bb,
F, Eb (in addition to C) key signatures for instruments not tuned in C. Strobe
Patterns display in the note window corresponding to the note sounded for
instruments tuned in, B b, F, E b (and C.)
STROBE DISC DRIVES: Each of
the 12 strobe discs is driven by an individual microprocessor-controlled
computer-grade motor.
PRE-PROGRAMMED TEMPERAMENTS:
Equal Temperament, Pythagorean Tuning, Just Intonation-Major Mode, just
Intonation-Minor Mode, Quarter Comma Mean-Tone, Werckmeister-111, Kimberger-III,

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.
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
SEMITONE - Accurate to 1/10 of a Cent, or 0.006%
CALIBRATION TO ANY PITCH STANDARD -
A=440 Default.
