Remarks
The Powertune system is adjustable to a pitch
accuracy of .2 Cent. However, this will cause
tuning functions to take slightly longer, and in
live applications a relaxed accuracy is advisable.
There are 6 levels of setting. The factory preset
setting will show 4 green flashing LEDs, indicating
that you are using an accuracy setting of approx.
1 Cent, which is practical for most applications.
Relaxing this setting will cause the overall tuning
process to run at a faster rate, and this can be
useful in live applications. In the studio, you would
want the maximum accuracy measurable. In this
case, range will be changed and adjusted by
rotating the MCK. The high end of accuracy (.2 Cent)
is indicated by 6 green LEDs. The low end (i.e.,
fastest speed) is indicated by one green LED.
Even at the low end, accuracy of tuning is still
2.5 Cent! To store your chosen setting, press display
once. You will leave Setup Mode automatically.
