In order to increase operation safety only send the necessary MIDI data to the SPECTRALIZER. 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 UP and DOWN LEDS 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 APPLY LED illuminates indica- ting that a program change command is received.

signal and clip indicators. The metering offers 1dB resoltion for

the last 3dB before 0dB.

The first LED in the OUTPUT PPM meter is a signal (SIG.) 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 SIG. LED is not illuminating you have a first indication of a faulty digital signal flow.

The last LED of the OUTPUT PPM meter is a CLIP LED. The LED illuminates if the digital signal is too hot causing digital distor- tion.
