PASSIVE/ACTIVE INPUT JACK

This input jack is designed to accommodate both “passive” instruments, and most “active” instruments. A passive instrument has no built-in preamp and does not use a battery, while an “active” bass utilizes a battery operated preamp for gain, tone controls, or both. The Passive/ Active Input will work with all instruments having a maximum output of less than 1 volt RMS. Some active pickups, such as EMG, Bartolini, etc., use batteries for operation and will work per- fectly using this input. Additionally, instruments made by Pedulla, Tobias, Sadowsky, Modulus Graphite, etc., have active electronics that are suited for use in the Passive/Active input.

Generally speaking, try this input first. If you hear a small amount of distortion and the preamp clip LED is not activated, try using the Active input jack. If using the Active input does not correct any audible distortion, check the battery in your bass.
