In order to increase operation safety only send the necessary
MIDI data to the S PECTRALIZER . Unnecessary information might
lead to system failure.
You can use MIDI to create a MIDI fade out, if you are
working with a digital console that does not provide master
inserts. The U
P and D OWN LED S illuminate indicating that a
volume change command is received.
You can also switch between presets with the MIDI program
change command. This can especially be useful, when you are
mastering a song, for example, that requires different settings
for chorus, refrain, or bridge. The A
PPLY LED illuminates indica-
ting that a program change command is received.

The O UTPUT LED chains are PPM (peak level) meters with
signal and clip indicators. The metering offers 1 dB resoltion for
the last 3 dB before 0 dB.
The first LED in the O UTPUT PPM meter is a signal (S IG .) LED
to indicate that a valid digital source is connected and detected.
This LED helps you to verify the signal flow within a digital
processing chain. If one S
IG . LED is not illuminating you have a
first indication of a faulty digital signal flow.
The last LED of the O UTPUT PPM meter is a C LIP LED. The LED
illuminates if the digital signal is too hot causing digital distor-
tion.
