Clari-Fi button: Press this button to engage Clari-Fi, which automatically applies the appropriate amount of Sound Restoration technology required by the signal coming into the amp, whether through high-level inputs, low-level inputs, or wirelessly. Leave Clari-Fi engaged since it automatically detects and restores compressed music files and will have no effect on uncompressed sources.
GTR AMPLIFIERS Setting the input level controls To match your amplifier’s input sensitivity (gain) to your source unit’s output level, we recommend the following procedure: A. Turn both input level controls counterclockwise to MIN (minimum). B. Play a dynamic music track through your source unit. Turn the source unit’s volume control to the 3/4 position. C.
