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). If you use this feature to stop a strobe pattern, after the tuner
wheel is stationary, the display indicates how many cents sharp or flat the tuner has been adjusted, giving you an exact
reading of the difference from correct intonation for each note observed. (These buttons are also used as select buttons
under some of the Temperament and Stretch Menu screens.)
3. EIGHTY-CHARACTER LCD MENU SCREEN - Simplicity and ease of operation are enhanced by the intuitive and
user-friendly menu screen displays which address all the functional features of the tuner.
4. FOUR MENU-DRIVEN FUNCTION KEY BUTTONS - These four keys are each defined by the specific menu-
screen information for each of the various operational modes of the tuner. They permit great flexibility and simple user
interaction with the Strobe Center 5000.
5. ENTER - This push button is used to select specific values of Pitch Up or Pitch Down deviations when editing
customized temperament and/or stretch tuning files used in specialized tuning applications. It is also used for some of
the user selections in the programming menu of the tuner.
6. MUTE - The Strobe Center 5000 may be used on-stage during a performance with the external Input patched through
to the Output. The Mute Mode disconnects the internal patch through path to permit silent on-stage tuning. The Mute
is a toggle function. Press the key once to engage the Mute Mode ("M" will be indicated on the display panel when this
feature is activated). Press the key again to restore normal patch through operation.
7. SELF-CONTAINED MICROPHONE & EXTERNAL PATCH THROUGH INPUT- The Strobe Center 5000 is
equipped with a built-in condenser microphone as a complete self-contained tuning center. The intonation of notes
sounded into this microphone will immediately be visible on the corresponding tuning disc. The front panel also includes
connectors for an external Input and patch through to Output. The internal microphone is automatically disconnected
whenever the external Input is used for an outboard microphone or other electrical input.
8. DISPLAY +2 / -1 - Improved pattern clarity is achieved for the hard to see lower and upper octaves by pressing this
key once or twice. The +2 Mode lifts the bass notes up by two octaves into the middle of the strobe discs for easier
readability. Similarly, the -1 Mode drops the treble notes down one octave on the strobe wheels. Combining this feature
with both Advanced Image Clarifier filtering and automated contrast adjustment makes the Strobe Center 5000 very easy
to use.
9. KEY - Selectable key signature is used to change the Strobe Center 5000 to the key in which your instrument is tuned.
You no longer have to transpose your note to the key of C. Press this button once, twice, or three times to adjust the tuner
between the keys of C, B=, F, and E=. Sound your note and the tuner will show your intonation on the tuning disc
corresponding to the note you are playing.
10. USER SELECTABLE PITCH - The International Standard Pitch of A=440 Hertz (cycles per second) can be raised
or lowered to any tuning frequency you desire. The adjustment range for Middle A (A4) is from A=350 Hz to
A=550 Hz. This modified standard pitch can be memorized in the Strobe Center 5000 so that the tuner starts up
calibrated for the selected pitch of your preference. The pitch currently selected for "A" is displayed by the LCD
indicator screen.
11. SELECTABLE TEMPERAMENTS - The microprocessor circuitry allows you to choose the equal tempered scale
or one from a list of seven preprogrammed non-equally tempered tunings. You may program and save personal custom
temperaments by entering the tempered values for each of the twelve notes in the chromatic scale in 1/10 of 1 cent
increments. The current temperament in use is shown in the LCD display panel whenever it is different from the equal
tempered scale.
12. STRETCH TUNING FROM STANDARD OR CUSTOM TABLES - The Strobe Center 5000 has 8 built-in stretch
