Peterson Strobe Center 5000-II Tuner
Accuracy within .001 of a semi-tone!

Peterson Tuners result from over 40 years of experience in making the finest quality tuning and ear training devices for the music industry. The engineers at Peterson, through extensive research, have made significant advances in strobe tuner technology. These advances have culminated in our current line of products. Peterson is the leading manufacturer of precision tuning equipment for the music industry worldwide.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 presentFACTORY-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 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.
