INTRODUCTION The peterson Strobe Center™ 5000 II is the most advanced tuning device ever developed. Precision microprocessor digital and motor control technologies have been combined with the 12 individual strobe-wheel tuning method to provide a versatile tuner with unsurpassed accuracy and features. The SC-5000 II is designed to be easier to read and even simpler in operation than its predecessor, the SC-5000.
The built-in microphone will pick up an instrument from across a relatively quiet room. However, if you are working in a noisy environment it may be helpful to use an external microphone to be more selective and point the microphone directly at the instrument you wish to tune. At this point you simply play the note you wish to tune. Each of the 12 tuning wheels is marked with a note corresponding to the chromatic scale.
2. PITCH UP / PITCH DOWN arrows - Precision digital Vernier Control permits you to sharpen or flatten the pitch of the SC-5000 to measure the correctness of your own intonation with an accuracy of 1/1000 of a semitone. You can adjust the tuner sharp or flat over a range of one half semitone (50 cents) each way, with selectable resolution of 1/10, 1/2 or 1 cent increments (1 cent equals 1/100 semitone).
tables for tuning pianos or other slightly inharmonic instruments. You may also enter your own preferred stretch configuration. You may then save this information into memory. The chosen stretch configuration in use is displayed on the LCD display screen whenever Stretch Mode is engaged. STEP-BY-STEP INSTRUCTIONS FOR USING THE Strobe Center 5000 1. EQUAL TEMPERAMENT TUNING a.
always active and is set to either Low or High, corresponding to the lower or upper musical registers. Although the SC-5000 II contains imaging improvements which yield good results even for low frequency sounds when in the factorydefault “HI” setting, the strobe patterns for very low notes can be further clarified by changing to the “LOW” setting. This is now a one button function. a. ADJUSTING THE IMAGE CLARIFIER KEY=C A=440 00 ¢ HI SETUP IMAG 1 2 3 Key #1 calls up the Setup Menu.
SETUP MENU PLEASE SELECT MODE OPTN 1 FILE 2 RUN DIAG 3 Key #1 will call up additional option menus. Key #2 will bring you to the temperament and stretch file choice menu. Key #3 will return the tuner to the Run Mode Key #4 will call up factory diagnostics. 4 ii. Press the #1 key which is labeled OPTN (meaning Options) and you will first see a screen for recalibrating the tuner to a different pitch standard.
rotational speed of each strobe disc is doubled beyond the normal tuning speed. The dark tuning indications are then shifted downward by one octave into the middle region of the tuning wheels. When in the Display +2 mode, press the Display key one more time and the tuner wheels are shifted to the -1 mode. Press the Display key one more time to return the Strobe Center 5000 back to the normal speed tuning mode.

Key #1 brings up the next screen menu. Key #2 updates selected values and returns to Run Mode. Key #3 lowers the pitch of A by 1 Hertz each time it is pressed. Key #4 raises the pitch of A by 1 Hertz each time it is pressed. RECALIBRATE TUNER? NOW A = 440 NEXT RUN 1 2 DOWN 3 UP 4 d.
5. CUSTOMIZING THE START-UP MEMORY SETTINGS If you desire the Strobe Center 5000 to always start-up in a different pitch standard than A=440, to a key other than "C" (band directors may desire B=, for example), or with different settings of the Image Clarifier and +2/-1 DISPLAY controls, it is easy to do. a. In the Run Mode menu, make the adjustment to the key you desire by pressing the KEY button as just described.
6. CHECKING INTONATION WITH THE SC-5000 When you desire to check your playing intonation, the tuner can assist in a very simple manner. You will need a partner to adjust the pitch of the tuner to match the intonation of the note(s) you are checking. When checking and adjusting your own intonation, it is useful to use an external microphone. Turn your back to the tuner while playing your note so you don't see the indications on the tuning discs while your partner is making the adjustments.
enhance the resolution to 0.1 cent increments, first release the ENTER key, then press and hold it again while you press either PITCH UP or PITCH DOWN. The display screen always presents enhanced resolution of 0.5 cents and 0.1 cents by showing a decimal point and place: "xx.x ¢". When the tuner is set for enhanced resolution, the PITCH UP/DOWN buttons increment the tuning adjustments of the tuner in steps of 0.5 cents or 0.1 cents. This permits intonation measurements with an accuracy of 1/1000 semitone.
Because the (twelfth root of two) mathematical ratios of equal temperament are not exactly in tune (in both the scientific and historic sense of whole number ratios between all the twelve musical intervals in the chromatic scale - and particularly for major thirds, fourths and fifths), many performers of fixed tuned instruments, such as harpsichords and organs, prefer to have the instrument tuned so that certain keys and intervals sound more perfectly in tune and "sweeter" to their ears and those of the aud

very different. This may be the reason why music from that era was based mostly on octaves, fifths, and fourths and for which this tuning is said to sound extremely good. JUMA - JUST INTONATION (MAJOR PITCH) was created after musicians discovered the sweet richness of the perfectly aligned harmonic partial tones in the major third whole-number frequency-ratio of 5/4. The tuning uses as many whole number ratio perfect fifths, perfect major thirds, and perfect minor thirds as possible.
