Strobe Center 5000 II

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, and Young Temperaments.
  • BUILT-IN STRETCH TUNING TABLES for Concert Grand, Studio Grand, Small Grand, Full Upright, Console Upright, and Spinet pianos.
  • CUSTOM DEFINABLE MEMORY - Capacity for either 225 Custom Temperament files or 32 Custom Stretch Tables, or a combination (such as 112 Custom Temperaments and 16 Custom Stretch files.)
  • ELECTRICAL SPECIFICATIONS - Operates on 105 -125 or 210-240 Volts AC 50/60 Hz. Sensitive built-in condenser microphone. 1/4" jack input - for external microphone or pick-up - with Mute-controlled Patch-Through Output.
  • CONTROLS - Power On/Off Switch (rear panel,) Digital Pitch Vernier Up/Down Switches, Mute, Enter, Display +2/-l Selection, Key Selector, 4 Menu-controlled Function Switches, Electro-Luminescent LCD screen with 80 Characters, 12 Strobe-Wheel Tuning Windows each labeled with the corresponding note of the chromatic musical scale.
  • SIZE: 19.lcm x 54.Ocm x 36.2cm. Custom crafted wood case covered in black Moroccan grain, scuff resistant leatherette. Detachable Cover includes retainer for removable power cord.
  • NET WEIGHT: 11.8kg
  • 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.
  • INDEPENDENT MICROPROCESSOR -Controlled Strobe Discs Allow Unprecedented Versatility.
  • QUIET OPERATION - No noisy gear drives.
  • LED STROBE LIGHT SOURCES.
  • NO CALIBRATION OR WARM UP PERIOD REQUIRED.
  • ALL SOLID STATE.
  • SELF-CONTAINED CONDENSER MICROPHONE.
  • EXTERNAL PATCH-THROUGH INPUT WITH MUTE.
  • SELECTABLE PRE-PROGRAMMED AND CUSTOM ALTERNATE TEMPERAMENTS.
  • PROGRAMMABLE STRETCH TUNING.
  • RUGGED CARRYING CASE WITH COVER.
  • DUAL VOLTAGE 110 V or 220 V.
